Dieser Bericht erläutert die verschiedenen praktizierten Formen der Evaluierung und zeigt, dass „schlechte“ Evaluierung, zum Beispiel in Form von bloßen Vorher-Nachher-Vergleichen, zu verzerrten Bewertungen führt und typischerweise das Ergebnis beschönigt. Diese Schwächen bedeuten, dass die Träger finanzieller Bildungsmaßnahmen und die wirtschaftspolitisch Verantwortlichen die Wirkung ihrer Aktion eventuell überschätzen und die wahren Probleme nicht gut erkennen.

It allows quite disaggregate energy and emission analysis: Global Energy System Model (GENeSYS-MOD) uses a system of linear equations of the energy system to search for lowest-cost solutions for a secure energy supply, given externally defined constraints, mainly in terms of CO2-emissions. The general algebraic modeling system (GAMS) version of OSeMOSYS is updated to the newest version and, in addition, extended and enhanced to include e.g., a modal split for transport, an improved trading system, and changes to storages. The model can be scaled from small-scale applications, e.g., a company, to cover the global energy system. The paper also includes an application of GENeSYS-MOD to analyze decarbonization scenarios at the global level, broken down into 10 regions. Its main focus is on interdependencies between traditionally segregated sectors: electricity, transportation, and heating; which are all included in the model. Model calculations suggests that in order to achieve the 1.5–2 C target, a combination of renewable energy sources provides the lowest-cost solution, solar photovoltaic being the dominant source. Average costs of electricity generation in 2050 are about 4 cents/kWh (excluding infrastructure and transportation costs). %N 10 %P 1999-11-30 %V 10 %B Energies %B 10 (2017), 10, S. 1-28 %K Energieökonomik;Methodenforschung;Umwelt- und Ressourcenökonomik;Erneuerbare Ressourcen;Energiepolitik;Simulation;Ökonometrisches Modell %R http://dx.doi.org/10.3390/en10101468 %U http://hdl.handle.net/10419/200750 %0 Journal Article %8 13.12.2017 %M 9013065 %T Electrification of a City Bus Network: An Optimization Model for Cost-Effective Placing of Charging Infrastructure and Battery Sizing of Fast-Charging Electric Bus Systems %G Englisch %D 2017 %P S. 707-720 %Z DIWDok %F Aufsatz %F RefSSCI %1 DIW2017 %+ Alexander Kunith, Roman Mendelevitch, Dietmar Goehlich %A Kunith, Alexander;Mendelevitch, Roman;Goehlich, Dietmar %X The deployment of battery-powered electric bus systems within the public transportation sector plays an important role in increasing energy efficiency and abating emissions. Rising attention is given to bus systems using fast charging technology. This concept requires a comprehensive infrastructure to equip bus routes with charging stations. The combination of charging infrastructure and bus batteries needs a reliable energy supply to maintain a stable bus operation even under demanding conditions. An efficient layout of the charging infrastructure and an appropriate dimensioning of battery capacity are crucial to minimize the total cost of ownership and to enable an energetically feasible bus operation. In this work, the central issue of jointly optimizing the charging infrastructure and battery capacity is described by a capacitated set covering problem. A mixed-integer linear optimization model is developed to determine the minimum number and location of required charging stations for a bus network as well as the adequate battery capacity for each bus line. The bus energy consumption for each route segment is determined based on individual route, bus type, traffic, and other information. Different scenarios are examined in order to assess the influence of charging power, climate, and changing operating conditions. The findings reveal significant differences in terms of required infrastructure. Moreover, the results highlight a trade-off between battery capacity and charging infrastructure under different operational and infrastructure conditions. This paper addresses upcoming challenges for transport authorities during the electrification process of the bus fleets and sharpens the focus on infrastructural issues related to the fast charging concept. %N 10 %P 1999-11-30 %V 11 %B International Journal of Sustainable Transportation %B 11 (2017), 10, S. 707-720 %K Methodenforschung;Verkehr, Logistik und Tourismus;Ökonometrie;Verkehrsinfrastruktur;Verkehrsmittel;Verkehrsplanung;Transportlogistik;Öffentlicher Nahverkehr;Verkehrswissenschaft;Analyse;Öffentliche Investition;Private Infrastrukturinvestition %R https://doi.org/10.1080/15568318.2017.1310962 %0 Journal Article %8 01.03.2017 %M 9011758 %T Improving the Quality of Care for the Elderly Is of High Relevance for all Age Groups: Six Questions for Marco Giesselmann %G Englisch %D 2017 %P S. 109 %Z Sb 89 DIW Econ. %F Aufsatz %F Aufsatz %1 DIW2017 %U http://www.diw.de/documents/publikationen/73/diw_01.c.553791.de/diw_econ_bull_2017-09-2.pdf %A Giesselmann, Marco;Wittenberg, Erich %N 9 %P 1999-11-30 %V 7 %B DIW Economic Bulletin %B 7 (2017), 9, S. 109 %K Private Haushalte und Familien;Demographie und Bevölkerung;Methodenforschung;Wohlfahrtsstaat;Armut;Kulturökonomie;Politik;Volkswirtschaftliche Gesamtrechnung;Lebensqualität;Deutschland %U http://hdl.handle.net/10419/155381 %0 Journal Article %8 01.03.2017 %M 9011757 %T Policy Goals in the Eyes of the Public: Preservation of the Liberal Democratic Order Remains Most Important %G Englisch %D 2017 %P S. 97-108 %Z Sb 89 DIW Econ. %F Aufsatz %F Aufsatz %1 DIW2017 %U http://www.diw.de/documents/publikationen/73/diw_01.c.553789.de/diw_econ_bull_2017-09-1.pdf %+ Marco Giesselmann, Nico A.

In view of scientific and public discourses on prosperity, this report analyzes how voting-eligible Germans, the electorate, rated the significance of different policy areas in 2013 and again at the beginning of 2017. It is based on two representative surveys conducted together with Kantar Public (formerly TNS Infratest), in which respondents were asked to rate the relevance of various policy areas. The areas included were based on the ten social indicators favored by the study commission, “Growth, Prosperity and Quality of Life,” and 20 out of the 46 indicators the German government uses in its “Living Well in Germany” Report to describe quality of life. This report shows that the majority of German citizens do indeed view the areas which are described by the indicators as important policy dimensions. In both 2013 and 2017, “preserving democracy” had the highest relevance. In 2017, “improved care for old people” was number two, and a “more effective battle against crime” took (by a very small margin) third place, followed by “full employment.” While there is a high consensus on the importance of these four goals, the assessment of the importance of further policy goals varies greatly across people, and there are also clear systematic differences in the relevance of policy areas among different social groups. The issue of refugees does not appear as a policy goal in the classifications of the commission and the government, which iswhy it was not included in the survey. %N 9 %P 1999-11-30 %V 7 %B DIW Economic Bulletin %B 7 (2017), 9, S. 97-108 %K B59;D63;H11;I32;Z18 %K Private Haushalte und Familien;Demographie und Bevölkerung;Methodenforschung;Wohlfahrtsstaat;Armut;Kulturökonomie;Politik;Volkswirtschaftliche Gesamtrechnung;Lebensqualität;Deutschland %U http://hdl.handle.net/10419/155380 %0 Journal Article %8 28.02.2017 %M 9011742 %T Politikziele im Spiegel der Bevölkerung: Erhalt der freiheitlich-demokratischen Ordnung weiterhin am wichtigsten %G Deutsch %D 2017 %P S. 139-151 %Z Sb 89 Wochenbericht %F Aufsatz %F Aufsatz %1 DIW2017 %U http://www.diw.de/documents/publikationen/73/diw_01.c.553627.de/17-9-1.pdf %+ Marco Giesselmann, Nico A.

Angesichts wissenschaftlicher und öffentlicher Diskurse zum Thema Wohlstand analysiert dieser Bericht, wie die Wahlberechtigten in Deutschland die Bedeutung verschiedener Politikziele 2013 und zu Beginn des Jahres 2017 einschätzten. Grundlage sind zwei mit Kantar Public (vormals TNS Infratest) durchgeführte repräsentative Befragungen, in denen die Relevanz verschiedener Politikziele direkt ermittelt wurde. Die Auswahl der Ziele orientierte sich dabei an den von der Enquete- Kommission „Wachstum, Wohlstand, Lebensqualität“ ausgewählten zehn Wohlstandsindikatoren, die die Ergebnisse von Politik quantifizieren, sowie an 20 der 46 von der Bundesregierung ausgewählten Indikatoren, welche die Lebensqualität („Gut leben in Deutschland“) beschreiben sollen. Dieser Bericht zeigt, dass diese Indikatoren tatsächlich von den Bürgerinnen und Bürgern überwiegend als wichtige Politikziele angesehen werden. An der Spitze der Relevanz lag 2013 wie 2017 der Erhalt der Demokratie. Auf Platz zwei landet 2017 die Verbesserung der Pflege alter Menschen und den dritten Rang nimmt eine wirksamere Bekämpfung der Kriminalität ein, der ein etwas höheres Gewicht als Vollbeschäftigung zugemessen wird. Gleichzeitig zeigt sich, dass die Menschen verschiedene Politikbereiche erkennbar unterschiedlich gewichten. Zusätzlich wird deutlich, dass es auch systematische Unterschiede in der Relevanz von Politikbereichen bei verschiedenen sozialen Gruppen gibt. Nach dem Themenbereich „Geflüchtete“ wurde nicht gefragt, da die Zahl der Geflüchteten in beiden Indikatorensystemen nicht als Politikbereich enthalten ist. %N 9 %P 1999-11-30 %V 84 %B DIW Wochenbericht %B 84 (2017), 9, S. 139-151 %K B59;D63;H11;I32;Z18 %K Methodenforschung;Private Haushalte und Familien;Demographie und Bevölkerung;Wohlfahrtsstaat;Armut;Kulturökonomie;Politik;Volkswirtschaftliche Gesamtrechnung;Lebensqualität;Deutschland %U http://hdl.handle.net/10419/155389 %0 Journal Article %8 29.06.2017 %M 9012317 %T The Role of Morbidity for Proxy-Reported Well-Being in the Last Year of Life %G Englisch %D 2017 %P S. 1795-1809 %Z DIWDok %F Aufsatz %F RefSSCI %1 DIW2017 %+ Katharina Gerlach, Nilam Ram, Frank J.

Here, we draw from and test theoretical perspectives that health-related vulnerabilities undermine the experience and skills older adults typically use to maintain well-being (Charles, 2010). To do so, we examined how various morbidity factors shape final-year well-being trajectories. We applied change score models to retrospective proxy-reports from the Socio-Economic Panel (N = 1,776; age at death = 19–101 years; 47% women) and covary for characteristics of the deceased and the bereaved proxy. Terminal decline in proxy-reported well-being amounted to 0.57 SD in less than a year, with larger individual differences at 3 months versus 12 months before death. Declines were reportedly steeper for those in poor health, need of care, not dying from sudden causes of death, dying with cancer, and not dying at home. People who entered their final year with preserved well-being and cognition experienced steeper final-year decrements. Morbidity factors conjointly accounted for less than 20% of variance, indicating that health decrements shape final-year well-being in multifaceted ways, but are not the be-all and the end-all of why well-being declines for some, but not for others. Unique effects of particular morbidity factors were modest, suggesting that prevailing multimorbidity makes the particular conditions in part interchangeable. Extending self-report data typically available until 1 year before death, our findings suggest that proxy-based results move our understanding of terminal well-being decline further. %N 9 %P 1999-11-30 %V 53 %B Developmental Psychology %B 53 (2017), 9, S. 1795-1809 %K Demographie und Bevölkerung;Soziales und Gesundheit;Lebenszufriedenheit;Ältere Menschen;Methodenforschung;Befragung;Panel;SOEP %R http://dx.doi.org/10.1037/dev0000368 %0 Journal Article %8 21.02.2018 %M 9013341 %T Reasonable Sample Sizes for Convergence to Normality %G Englisch %D 2017 %P S. 7074-7087 %Z DIWDok %F Aufsatz %F RefSCI %1 DIW2017 %+ Carsten Schröder, Shlomo Yitzhaki %A Schröder, Carsten;Yitzhaki, Shlomo %X The central limit theorem says that, provided an estimator fulfills certain weak conditions, then, for reasonable sample sizes, the sampling distribution of the estimator converges to normality.

However, so far making data available has little impact on a researcher’s reputation. Thus, data sharing can be conceptualized as a social dilemma. In the presented study we investigated the influence of the researcher's personality within the social dilemma of data sharing. The theoretical background was the appropriateness framework. We conducted a survey among 1564 researchers about data sharing, which also included standardized questions on selected personality factors, namely the so-called Big Five, Machiavellianism and social desirability. Using regression analysis, we investigated how these personality domains relate to four groups of dependent variables: attitudes towards data sharing, the importance of factors that might foster or hinder data sharing, the willingness to share data, and actual data sharing. Our analyses showed the predictive value of personality for all four groups of dependent variables. However, there was not a global consistent pattern of influence, but rather different compositions of effects. Our results indicate that the implications of data sharing are dependent on age, gender, and personality. In order to foster data sharing, it seems advantageous to provide more personal incentives and to address the researchers’ individual responsibility. %N 8 %P 1999-11-30 %V 12 %B PloS one %B 12 (2017), 8, e0183216 %K Methodenforschung;Forschungsdaten;Open Access;Wissenschaftler;Wissenschaftliches Arbeiten %R https://doi.org/10.1371/journal.pone.0183216 %U http://hdl.handle.net/10419/200704 %0 Journal Article %8 07.08.2017 %M 9012471 %T "What Else Are You Worried about?" - Integrating Textual Responses into Quantitative Social Science Research %G Englisch %D 2017 %P 34 S. %Z Online;DIWDok %F Aufsatz %F RefSSCI %1 DIW2017 %+ Julia M.

Tools developed recently in the domain of natural language processing offer a wide range of options for the automated analysis of such textual data, but their implementation has lagged behind. In this study, we demonstrate straightforward procedures that can be applied to process and analyze textual data for the purposes of quantitative social science research. Using more than 35,000 textual answers to the question “What else are you worried about?” from participants of the German Socio-economic Panel Study (SOEP), we (1) analyzed characteristics of respondents that determined whether they answered the open-ended question, (2) used the textual data to detect relevant topics that were reported by the respondents, and (3) linked the features of the respondents to the worries they reported in their textual data.

Here, we want to make use of that. We employ a rich dataset provided by Media Tenor International, based on sentiment analysis of opinion-leading media in Germany from 2001 to 2014, transformed into several monthly indices. German industrial production is predicted in a real-time out-of-sample forecasting experiment and media indices are compared to a huge set of alternative indicators. Media data turn out to be valuable for 10- to 12-month horizon forecasts, which is in line with the lag between monetary policy announcements and their effect on industrial production.

We fill this gap by introducing the R package FFTrees. In this paper, we explain how FFTs work, introduce a new class of algorithms called fan for constructing FFTs, and provide a tutorial for using the FFTrees package. We then conduct a simulation across ten real-world datasets to test how well FFTs created by FFTrees can predict data. Simulation results show that FFTs created by FFTrees can predict data as well as popular classification algorithms such as regression and random forests, while remaining simple enough for anyone to understand and use. %N 4 %P 1999-11-30 %V 12 %B Judgment and Decision Making %B 12 (2017), 4, S. 344-368 %K Private Haushalte und Familien;Methodenforschung;Entscheidungstheorie;Entscheidung;Heuristisches Verfahren;Prognoseverfahren %U http://hdl.handle.net/10419/201523 %0 Journal Article %8 08.03.2017 %M 9011819 %T Design of Reforms with Time-Inconsistent Voters %G Englisch %D 2017 %P S. 748-761 %Z DIWDok %F Aufsatz %F RefSSCI %1 DIW2017 %+ Jisoo Hwang, Johanna Mollerstrom %A Hwang, Jisoo;Mollerstrom, Johanna %X Widespread agreement that a political reform is necessary is no guarantee that it is actually undertaken in a timely manner. There is often a delay before action is taken and reform packages that would be most efficient to implement all at once are often done only gradually. We propose a theoretical model explaining this behavior and show that when voters have present-biased, time-inconsistent preferences, gradualism can arise in equilibrium and be welfare-enhancing. This is because without the possibility for gradualism, time-inconsistent voters would delay implementing the reform even more. Using a citizen candidate model, we allow the agenda setter, who decides which reform schedule to put to vote, to be endogenously determined. We show that voters who are aware of their own time inconsistency can use the election of the agenda setter as a commitment device and appoint an agent who is more patient than the median voter in order to avoid full procrastination and to achieve efficiency-maximizing gradualism. %N 3 %P 1999-11-30 %V 19 %B Journal of Public Economic Theory %B 19 (2017), 3, S. 748-761 %K Private Haushalte und Familien;Wahlverhalten;Methodenforschung;Reform %R http://dx.doi.org/10.1111/jpet.12229 %0 Journal Article %8 09.11.2018 %M 9014487 %T Anchored Calibration: From Qualitative Data to Fuzzy Sets %G Englisch %D 2017 %P 12 S. %Z DIWDok %F Aufsatz %F Main %1 DIW2017 %+ Nicolas Legewie %A Legewie, Nicolas %X Combining qualitative data and qualitative comparative analysis (QCA) holds great analytic potential because it allows for detailed insights into social processes as well as systematic cross-case comparisons. But despite many applications, continuous methodological development, and some critique of measurement practices, a key procedure in using qualitative data for QCA has hardly been discussed: how to translate, or "calibrate," the information in qualitative data into formalized fuzzy sets? This calibration has crucial impact on QCA results. Hence, reliability of calibration is a decisive factor in a study's overall quality and credibility. I develop "anchored calibration" as an approach that addresses important gaps in prior approaches and helps enhancing calibration reliability. Anchored calibration involves three steps: conceptualizing conditions and outcome(s) in a systematic framework, anchoring this framework with empirical data pieces, and using the anchored framework to assign membership scores to cases. I present the tasks necessary to complete these three steps, drawing examples from an in-depth interview study on upward educational mobility. %N 3 %P 1999-11-30 %V 18 %B Forum: Qualitative Sozialforschung %B 18 (2017), 3, Art. 14, 12 S. %K Methodenforschung;Datenerhebung;Fuzzy Sets;Qualitative Methode %R http://dx.doi.org/10.17169/fqs-18.3.2790 %U http://hdl.handle.net/10419/233554 %0 Journal Article %8 24.11.2015 %M 9008686 %T About Attitudes and Perceptions: Finding the Proper Way to Consider Latent Variables in Discrete Choice Models %G Englisch %D 2017 %P S. 475-493 %Z DIWDok %F Aufsatz %F RefSSCI %1 DIW2017 %+ Francisco J.

This discussion is of importance, as the majority of papers considering attitudinal latent variables just take these as attributes affecting directly the utility of a certain alternative, while systematic taste variations are rarely considered and perceptions are mostly ignored. The results of our case study show that perceptions may indeed affect the decision making process and that they are able to capture a significant part of the variability that is normally explained by alternative specific constants. Furthermore, our results indicate that attitudes may be a reason for systematic taste variations, and that a proper categorization of latent variables, in accordance with underlying theory, may outperform the customary assumption of linearity. %N 3 %P 1999-11-30 %V 44 %B Transportation : Planning, Policy, Research, Practice %B 44 (2017), 3, S. 475-493 %K Methodenforschung;Entscheidungstheorie %R http://dx.doi.org/10.1007/s11116-015-9663-5 %0 Journal Article %8 08.05.2017 %M 9012040 %T Judicial Behavior and Devolution at the Privy Council %G Englisch %D 2017 %P 40 S. %Z DIWDok %F Aufsatz %F Main %1 DIW2017 %+ Sofia Amaral-Garcia, Nuno Garoupa %A Amaral-Garcia, Sofia;Garoupa, Nuno %X In this article, we study judicial behavior at the Judicial Committee of the Privy Council (JCPC). British judges in general, and British high court judges in particular, are perceived to be independent and isolated from political pressure and interference. Furthermore, these judges tend to show a particularly high rate of consensus. This has led many scholars to consider that, contrarily to what holds for several other courts around the world (such as the US Supreme Court), the attitudinal model does not find support when British higher court judges are considered. In this paper we assess whether similar conclusions might be drawn from the JCPC, another British court of last resort. We create a unique dataset to study empirically decisions of the JCPC and investigate the extent to which judges exhibit different judicial behavior depending on the type of appeal being brought to the court, i. e., Commonwealth, devolution and domestic appeals. Our results indicate a higher polarization of judicial behavior in the context of devolution appeals (as measured by separate opinions). We discuss these results in the context of the comparative judicial behavior literature and the role of courts in the common law world (with particular reference to human rights). %N 3 %P 1999-11-30 %V 13 %B Review of Law and Economics %B 13 (2017),3, 20150013, 40 S. %K K0 %K Methodenforschung %R https://doi.org/10.1515/rle-2015-0013 %0 undefined %8 16.06.2017 %M 9012246 %T Replikationen, Reputation und gute wissenschaftliche Praxis %D 2017 %P S. 154-158 %Z DIWDok %F Aufsatz %F RefESCI %1 DIW2017 %+ Benedikt Fecher, Mathis Fräßdorf, Marcel Hebing, Gert G.

Against this background, the replicability of scientific results, particularly replication studies, have been discussed as a hallmark of good scientific practice. Thus, failures of replication raises the public's mistrust in the scientific enterprise. More and systematic replication studies are discussed as a solution to counter recent issues of analyses which were found to be methodological unsound or erroneous. Nevertheless, few replication studies are being conducted. The aims of this article are to introduce the main issues regarding the replicability of scientific results, and to suggest policy measures in order to raise the number of replication studies that build upon the implicit mechanisms that structure academic reputation. %N 2-3 2-3 %P 1999-11-30 %V 68 %B Information, Wissenschaft & Praxis %B 68 (2017), 2, S. 154-158 %K Methodenforschung;Wissenschaftliches Arbeiten;Forschungsdaten;Forschung %R https://doi.org/10.1515/iwp-2017-0025 %0 Journal Article %8 15.12.2016 %M 9011327 %T The Informed Consent to Record Linkage in Panel Studies: Optimal Starting Wave, Consent Refusals, and Subsequent Panel Attrition %G Englisch %D 2017 %P S. 131-143 %Z DIWDok %F Aufsatz %F RefSSCI %1 DIW2017 %+ Philipp Eisnecker, Martin Kroh %A Eisnecker, Philipp;Kroh, Martin %X Social scientists increasingly link survey data with administrative records. However, data protection legislation often requires respondents’ informed consent prior to record linkage. This has confronted research with nontrivial refusal rates in combination with selectivity of the consent decision. In longitudinal surveys, linkage requests may also increase attrition rates in subsequent waves, as many respondents perceive record linkages negatively. Hence, in panel surveys, both nonresponse forms potentially bias the resulting datasets. The present paper examines (a) whether we can minimize consent refusals in a longitudinal survey by varying which survey wave includes the linkage request and (b) whether such requests increase subsequent attrition. To test this, we implement a randomized survey experiment within a face-to-face household panel survey focusing on migrants in Germany. Respondents of the IAB-SOEP Migration Sample, conducted by the Institute for Employment Research (IAB) and the Socio-Economic Panel study (SOEP), were randomly allocated into three groups: first, a control group without record linkage; a second group that was asked in wave 1 (2013) to allow data linkage to administrative employment and benefits records held by the Federal Employment Agency; and a third group that was asked the same question in wave 2 (2014). We found neither significant differences in consent rates when introducing the request in wave 1 or 2 nor significant differences in panel attrition in subsequent waves. Therefore, results suggest that requesting consent to link records in wave 1 of a panel study provides the largest quantity of linked data without inflating panel attrition. %N 1 %P 1999-11-30 %V 81 %B The Public Opinion Quarterly %B 81 (2017), 1, S. 131-143 %K Methodenforschung;Befragung;Panel;Sozialwissenschaft %R http://dx.doi.org/10.1093/poq/nfw052 %0 Journal Article %8 03.03.2017 %M 9011773 %T Measuring the Consistency of Cross-Sectional and Longitudinal Income Information in EU-SILC %G Englisch %D 2017 %P S. 30-52 %Z DIWDok %F Aufsatz %F RefSSCI %1 DIW2017 %+ Kristina Krell, Joachim R.

It is therefore crucial to ensure that the data are of the highest quality and international comparability. This paper is aimed at identifying unexpected developments in income levels, income mobility, and inequality in the EU-SILC data between 2005 and 2009. We examine the consistency of EU-SILC by comparing cross-sectional results with findings based on two-year longitudinal samples. Although the data represent similar populations, for several countries the results of this comparison differ widely. One important outcome is the high degree of variability over time in countries that obtain their income information from register data. This suggests methodological challenges in the clear designation of new subsample members, in the reweighting of the data, in imputation of missing values, and in other areas. %N 1 %P 1999-11-30 %V 63 %B The Review of Income and Wealth %B 63 (2017), 1, S. 30-52 %K C89;D31;I39 %K Private Haushalte und Familien;Demographie und Bevölkerung;Panel;Soziale Ungleichheit;Mobilität;Methodenforschung;Wohlfahrtsanalyse %R http://dx.doi.org/10.1111/roiw.12202 %0 Journal Article %8 14.07.2017 %M 9012392 %T Risk Forecasting in (T)GARCH Models with Uncorrelated Dependent Innovations %G Englisch %D 2017 %P S. 121-137 %Z DIWDok %F Aufsatz %F RefSSCI %1 DIW2017 %+ Benjamin Beckers, Helmut Herwartz, Moritz Seidel %A Beckers, Benjamin;Herwartz, Helmut;Seidel, Moritz %X (G)ARCH-type models are frequently used for the dynamic modelling and forecasting of risk attached to speculative asset returns.

For a cross section of 18 stock market indices, we notice that (threshold) (T)GARCH-implied model innovations are likely at odds with the commonly held IID assumption. Two complementary strategies are pursued to evaluate the conditional distributions of consecutive TGARCH innovations, a non-parametric approach and a class of standardized copula distributions.

In the Entitlement treatment, the right to be the proposer is allocated to the personin the pair who performed better in a previously conducted math task. Compared to behavior in the control treatment, where the roles are randomly allocated, the proposers increase their strategic demands and offer a smaller share of the pie to the responder in the Entitlement treatment. This result is drivenentirely by female proposers; when earning their role, they significantly lower their offers, whereas male proposers do not behave differently than when roles are randomly allocated. This is in line with previous research suggesting that women are more sensitive to contextual factors and social cues, meaning that strengthening feelings of entitlement could be a way to decrease gender differences innegotiation behavior. %P 1999-11-30 %C Berlin %I DIW Berlin %7 Newer version published at DP 1756 (2018) %B Diskussionspapiere / Deutsches Institut für Wirtschaftsforschung ; 1708 %K Methodenforschung;Demographie und Bevölkerung;Experiment;Geschlecht;Frauen;Männer;Verhaltensforschung;Spieltheorie %U http://hdl.handle.net/10419/182560 %0 Book %8 12.12.2017 %M 9013050 %T Bayesian Inference for Structural Vector Autoregressions Identified by Markov-Switching Heteroskedasticity %G Englisch %D 2017 %P 37 S. %Z Sb 89 Diskuss. %F Mono %F WP %1 DIW2017 %U http://www.diw.de/documents/publikationen/73/diw_01.c.573492.de/dp1707.pdf %+ Helmut Lütkepohl, Tomasz Woźniak %A Lütkepohl, Helmut;Woźniak, Tomasz;Deutsches Institut für Wirtschaftsforschung, DIW Berlin %X In order to identify structural shocks that affect economic variables, restrictions need to be imposed on the parameters of structural vector autoregressive (SVAR) models. Economic theory is the primary source of such restrictions. However, only over-identifying restrictions can be tested with statistical methods which limits the statistical validation of many just-identified SVAR models. In this study, Bayesian inference is developed for SVAR models in which the structural parameters are identified via Markov-switching heteroskedasticity. In such a model, restrictions that are just-identifying in the homoskedastic case, become over-identifying and can be tested. A set of parametric restrictions is derived under which the structural matrix is globally identified and a Savage-Dickey density ratio is used to assess the validity of the identification conditions. For that purpose, a new probability distribution is defined that generalizes the beta, F, and compound gamma distributions. As an empirical example, monetary models are compared using heteroskedasticity as an additional device for identification. The empirical results support models with money in the interest rate reaction function. %P 1999-11-30 %C Berlin %I DIW Berlin %B Diskussionspapiere / Deutsches Institut für Wirtschaftsforschung ; 1707 %K C11;C12;C32;E32 %K Methodenforschung;Zeitreihe;Zeitreihenanalyse;Ökonometrie;Methode;Konjunkturforschung;Konjunkturbewegung;Heteroskedastizität;Schock %U http://hdl.handle.net/10419/172829 %0 Book %8 07.08.2017 %M 9012463 %T Designing a Global Energy System Based on 100% Renewables for 2050: GENeSYS-MOD: An Application of the Open-Source Energy Modelling System (OSeMOSYS) %G Englisch %D 2017 %P 40 S. %Z Sb 89 Diskuss. %F Mono %F WP %1 DIW2017 %U http://www.diw.de/documents/publikationen/73/diw_01.c.563040.de/dp1678.pdf %+ Konstantin Löffler, Karlo Hainsch, Thorsten Burandt, Pao-Yu Oei, Claudia Kemfert, Christian von Hirschhausen %A Löffler, Konstantin;Hainsch, Karlo;Burandt, Thorsten;Oei, Pao-Yu;Kemfert, Claudia;Hirschhausen, Christian von;Deutsches Institut für Wirtschaftsforschung, DIW Berlin %X This paper develops a path for the global energy system up to 2050, presenting a new application of the open source energy systems model OSeMOSYS to the community. It allows quite disaggregate energy and emission analysis: GENeSYS-MOD (Global Energy System Model) uses a system of linear equations of the energy system to search for lowestcost solutions for a secure energy supply, given externally defined constraints, mainly in terms of CO2-emissions. The General Algebraic Modeling System (GAMS) version of OSeMOSYS is updated to the newest version and, in addition, extended and enhanced to include e.g. a modal split for transport, an improved trading system, and changes to storages. The model can be scaled from small-scale applications, e.g. a company, to cover the global energy system. The paper also includes an application of GENeSYS-MOD to analyze decarbonization scenarios at the global level, broken down into 10 regions. Its main focus is on interdependencies between traditionally segregated sectors: electricity, transportation, and heating. Model calculations suggests that in order to achieve the 1.5°-2° C target, a combination of renewable energy sources provides the lowest-cost solution, solar photovoltaic being the dominant source. Average costs of electricity generation in 2050 are about 4 €cents/kWh (excluding infrastructure and transportation costs). %P 1999-11-30 %C Berlin %I DIW Berlin %B Diskussionspapiere / Deutsches Institut für Wirtschaftsforschung ; 1678 %K C61;Q4;L9 %K Energieökonomik;Methodenforschung;Umwelt- und Ressourcenökonomik;Erneuerbare Ressourcen;Energiepolitik;Simulation;Ökonometrisches Modell %U http://hdl.handle.net/10419/168456 %0 Book %8 10.07.2017 %M 9012365 %T Towards an East German Wage Curve - NUTS Boundaries, Labour Market Regions and Unemployment Spillovers %G Englisch %D 2017 %P 30 S. %Z Sb 89 Diskuss. %F Mono %F WP %1 DIW2017 %U http://www.diw.de/documents/publikationen/73/diw_01.c.561418.de/dp1675.pdf %+ Reinhold Kosfeld, Christian Dreger %A Kosfeld, Reinhold;Dreger, Christian;Deutsches Institut für Wirtschaftsforschung, DIW Berlin %X The relevance of spatial effects in the wage curve can be rationalized by the model of monopsonistic competition in regional labour markets. However, distortions in extracting the regional unemployment effects arise in standard regional (i.e. NUTS) classifications as they fail to adequately capture spatial processes. In addition, the nonstationarity of wages and unemployment is often ignored. Both issues are particularly important in high unemployment regimes like East Germany where a wage curve is difficult to establish. In this paper, labour market regions defined by economic criteria are used to examine the existence of an East German wage curve. Due to the nonstationarity of spatial data, a global panel cointegration approach is adopted. By specifying a spatial error correction model (SpECM), equilibrium adjustments are investigated in time and space. The analysis gives evidence on a locally but not a spatially cointegrated wage curve for East Germany. %P 1999-11-30 %C Berlin %I DIW Berlin %B Diskussionspapiere / Deutsches Institut für Wirtschaftsforschung ; 1675 %K J30;J60;C33;R15 %K Arbeit und Beschäftigung;Mobilität;Arbeitslosigkeit;Arbeitsmarkt;Methodenforschung;Panel;Datenanalyse;Daten;Regionalwirtschaft und Infrastruktur;Regionalökonomik;Ökonometrisches Modell;Deutschland %U http://hdl.handle.net/10419/162818 %0 Book %8 04.07.2017 %M 9012341 %T Choosing between Different Time-Varying Volatility Models for Structural Vector Autoregressive Analysis %G Englisch %D 2017 %P 33 S. %Z Sb 89 Diskuss. %F Mono %F WP %1 DIW2017 %U http://www.diw.de/documents/publikationen/73/diw_01.c.560936.de/dp1672.pdf %+ Helmut Lütkepohl, Thore Schlaak %A Lütkepohl, Helmut;Schlaak, Thore;Deutsches Institut für Wirtschaftsforschung, DIW Berlin %X The performance of information criteria and tests for residual heteroskedasticity for choosing between different models for time-varying volatility in the context of structural vector autoregressive analysis is investigated. Although it can be difficult to find the true volatility model with the selection criteria, using them is recommended because they can reduce the mean squared error of impulse response estimates substantially relative to a model that is chosen arbitrarily based on the personal preferences of a researcher. Heteroskedasticity tests are found to be useful tools for deciding whether time-varying volatility is present but do not discriminate well between different types of volatility changes.

We find that relevant world events influence worries. For example, worries about peace peaked in 2003, the year of the Iraq War, with a considerable number of respondents also referring to the Iraq war in their text responses. Furthermore, we found that – controlling for these historical effects – worries about various topics such as health and the general economic situation increase with age. With increasing age, respondents also became more likely to answer the open-ended question. This suggests that the age increases in worries we found are not merely a result of an age-biased choice of worry items, but instead also hold for worries self-generated by the respondents. %P 1999-11-30 %C Berlin %I DIW Berlin %B Diskussionspapiere / Deutsches Institut für Wirtschaftsforschung ; 1671 %K C81;C83;I31;Z13 %K Daten;Mikroökonomik;Methodenforschung;Soziales und Gesundheit;Wohlfahrtsanalyse;Gesellschaft;Soziales Netzwerk;Lebenszufriedenheit;Deutschland %U http://hdl.handle.net/10419/162814 %0 Book %8 16.05.2017 %M 9012069 %T Testing the Fisher Hypothesis in the G-7 Countries Using I(d) Techniques %G Englisch %D 2017 %P 18 S. %Z Sb 89 Diskuss. %F Mono %F WP %1 DIW2017 %U http://www.diw.de/documents/publikationen/73/diw_01.c.558540.de/dp1667.pdf %+ Guglielmo Maria Caporale, Luis A.

The univariate analysis suggests than the differencing parameter is higher than 1 for most series in the former case, whilst the unit root null cannot be rejected for the majority of them in the latter case. The multivariate results imply that there exists a positive relationship, linking nominal interest rates to inflation; however, there is no evidence of the full adjustment of the former to the latter required by the Fisher hypothesis. %P 1999-11-30 %C Berlin %I DIW Berlin %B Diskussionspapiere / Deutsches Institut für Wirtschaftsforschung ; 1667 %K C22;C32;E43 %K Geld und Finanzmärkte;Methodenforschung;Themenliste Geldpolitik;Themenliste Die Welt der Finanzmärkte;G7-Staaten;Zeitreihenanalyse %U http://hdl.handle.net/10419/161660 %0 Book %8 28.04.2017 %M 9012006 %T Where Is the Consumer Center of St. Petersburg? %G Englisch %D 2017 %P 35 S. %Z Sb 89 Diskuss. %F Mono %F WP %1 DIW2017 %U http://www.diw.de/documents/publikationen/73/diw_01.c.557093.de/dp1666.pdf %+ Konstantin A.

As distance from the city center increases, both prices and population density diminish, for travel costs increase in terms of time and money. As manufacturing gradually leaves the cities, the importance of consumer amenities as attractors of population to the urban areas increases. The role of a business center is being replaced by the consumer center. In this paper, we identify the location of the consumer center of St. Petersburg - the second largest city in Russia and its former capital. For this purpose using the data from open sources in the Internet regarding the location of many different types of urban amenities, the indices of their spatial density are computed. Using the weights based on coefficients of spatial variation and survey-based weights, the individual indices are aggregated to two general centrality indices. Their unique maxima correspond to the city center of St. Petersburg, which is located on Nevsky prospekt, between Fontanka river and Liteinyi prospekt. %P 1999-11-30 %C Berlin %I DIW Berlin %B Diskussionspapiere / Deutsches Institut für Wirtschaftsforschung ; 1666 %K R14;R15;C43 %K Bauen und Wohnen;Stadtökonomik;Regionalökonomik;Statistik;Bodenwirtschaft;Ökonometrisches Modell;Verteilung;Methodenforschung;Regionalwirtschaft und Infrastruktur;Stadt %U http://hdl.handle.net/10419/157523 %0 Book %8 02.05.2017 %M 9012011 %T Reading between the Lines: Using Media to Improve German Inflation Forecasts %G Englisch %D 2017 %P 19 S. %Z Sb 89 Diskuss. %F Mono %F WP %1 DIW2017 %U http://www.diw.de/documents/publikationen/73/diw_01.c.557171.de/dp1665.pdf %+ Benjamin Beckers, Konstantin A.

Using a framed field experiment with 883 non-standard subjects, we show that none of the determinants of competitive behavior in general, including ability, self-confidence and risk aversion, provide a satisfying explanation for women’s substantive gender-related selection into competition. Nonetheless, women who are overconfident, i.e. over-estimate own abilities in performing a task, enter competition regardless of the gender-mix. Hence, the gender-pairing phenomenon is driven by women who correctly estimate or under-estimate own ability. We concluded that this is due to stereotypes about women’s underperformance compared to men. %P 1999-11-30 %C Berlin %I DIW Berlin %B Diskussionspapiere / Deutsches Institut für Wirtschaftsforschung ; 1662 %K C99;D83;J16 %K Ökonometrie;Methode;Experiment;Methodenforschung;Mikroökonomik;Information;Wissen;Geschlechterforschung;Bevölkerungsökonomik;Demographie und Bevölkerung;Private Haushalte und Familien %U http://hdl.handle.net/10419/157521 %0 Book %8 13.03.2017 %M 9011839 %T Macroeconomic Effects of Rental Housing Regulations: The Case of Germany in 1950-2015 %G Englisch %D 2017 %P 25 S. %Z Sb 89 Diskuss. %F Mono %F WP %1 DIW2017 %U http://www.diw.de/documents/publikationen/73/diw_01.c.554343.de/dp1649.pdf %+ Konstantin A. Kholodilin, Julien Licheron %A Kholodilin, Konstantin A.;Licheron, Julien;Deutsches Institut für Wirtschaftsforschung, DIW Berlin %X Despite rather skeptical attitude of the economists toward the state intervention in the housing markets, the policy makers and general public typically are supporting it. As a result, in many European countries, since World War I the rent and eviction controls as well as social housing policies remain an important element of the government economic policies. Nevertheless, the macroeconomic effects of such regulations are largely unknown. In this paper, we evaluate the effects of government rental market regulations on real house prices, price-to-rent, and price- to-income ratios, real rents, and new housing construction in Germany in 1950_2015. The regulations are measured by the indices developed by the authors based on a thorough analysis of the legal acts issued mostly by the central government but also by the regional authorities between 1914 and 2015. %P 1999-11-30 %C Berlin %I DIW Berlin %B Diskussionspapiere / Deutsches Institut für Wirtschaftsforschung ; 1649 %K C22;O18;R38 %K Bauen und Wohnen;Methodenforschung;Ökonometrie;Zeitreihenanalyse;Konjunktur, Wachstum, Wirtschaftsstruktur;Analyse;Entwicklung;Ländliche Entwicklung;Regierungspolitik;Makroökonomie;Mietpreis;Deutschland %U http://hdl.handle.net/10419/156141 %0 Book %8 15.02.2017 %M 9011682 %T Judicial Behavior and Devolution at the Privy Council %G Englisch %D 2017 %P 43 S. %Z Sb 89 Diskuss. %F Mono %F WP %1 DIW2017 %U http://www.diw.de/documents/publikationen/73/diw_01.c.552758.de/dp1643.pdf %+ Sofia Amaral-Garcia, Nuno Garoupa %A Amaral-Garcia, Sofia;Garoupa, Nuno;Deutsches Institut für Wirtschaftsforschung, DIW Berlin %X In this article, we study judicial behavior at the Judicial Committee of the Privy Council (JCPC). British judges in general, and British high court judges in particular, are perceived to be independent and isolated from political pressure and interference. Furthermore, these judges tend to show a particularly high rate of consensus. This has led many scholars to consider that, contrarily to what holds for several other courts around the world (such as the US Supreme Court), the attitudinal model does not find support when British higher court judges are considered. In this paper we assess whether similar conclusions might be drawn from the JCPC, another British court of last resort. We create a unique dataset to study empirically decisions of the JCPC and investigate the extent to which judges exhibit different judicial behavior depending on the type of appeal being brought to the court, i.e., Commonwealth, devolution and domestic appeals. Our results indicate a higher polarization of judicial behavior in the context of devolution appeals (as measured by separate opinions). We discuss these results in the context of the comparative judicial behavior literature and the role of courts in the common law world (with particular reference to human rights). %P 1999-11-30 %C Berlin %I DIW Berlin %B Diskussionspapiere / Deutsches Institut für Wirtschaftsforschung ; 1643 %K K0 %K Methodenforschung %U http://hdl.handle.net/10419/155361 %0 Book %8 09.02.2017 %M 9011656 %T Estimation of Structural Impulse Responses: Short-Run versus Long-Run Identifying Restrictions %G Englisch %D 2017 %P 12 S. %Z Sb 89 Diskuss. %F Mono %F WP %1 DIW2017 %U http://www.diw.de/documents/publikationen/73/diw_01.c.552328.de/dp1642.pdf %+ Helmut Lütkepohl, Anna Staszewska-Bystrova, Peter Winker %A Lütkepohl, Helmut;Staszewska-Bystrova, Anna;Winker, Peter;Deutsches Institut für Wirtschaftsforschung, DIW Berlin %X There is evidence that estimates of long-run impulse responses of structural vector autoregressive (VAR) models based on long-run identifying restrictions may not be very accurate. This finding suggests that using short-run identifying restrictions may be preferable.

Yet they are treated among researchers as an ideal to be professed but not practiced. To provide incentives and favorable boundary conditions for replication practice, the main stakeholders need to be aware of what drives replication. Here we investigate how often replication studies are published in empirical economics and what types of journal articles are replicated. We find that from 1974 to 2014 less than 0.1% of publications in the top-50 economics journals were replications. We do not find empirical support that mandatory data disclosure policies or the availability of data or code have a significant effect on the incidence of replication. The mere provision of data repositories may be ineffective, unless accompanied by appropriate incentives. However, we find that higher-impact articles and articles by authors from leading institutions are more likely to be subject of published replication studies whereas the replication probability is lower for articles published in higher-ranked journals. %P 1999-11-30 %C Berlin %I DIW Berlin %B Diskussionspapiere / Deutsches Institut für Wirtschaftsforschung ; 1640 %K A1;B4;C12;C13 %K Methodenforschung;Wissenschaftliche Methode;Wissenschaftliches Arbeiten;Wirtschaftswissenschaft;Ökonomische Ideengeschichte;Ökonometrie %U http://hdl.handle.net/10419/149903 %0 Book %8 24.01.2017 %M 9011561 %T Who Cares about Social Image? %G Englisch %D 2017 %P 35 S. %Z Sb 89 Diskuss. %F Mono %F WP %1 DIW2017 %U http://www.diw.de/documents/publikationen/73/diw_01.c.550891.de/dp1634.pdf %+ Jana Friedrichsen, Dirk Engelmann %A Friedrichsen, Jana;Engelmann, Dirk;Deutsches Institut für Wirtschaftsforschung, DIW Berlin %X This paper experimentally investigates how concerns for social approval relate to intrinsic motivations to purchase ethically. Participants state their willingness-to-pay for both a fair trade and a conventional chocolate bar in private or publicly. A standard model of social image predicts that all increase their fair trade premium when facing an audience. We find that the premium is higher in public than in private only for participants who preferred a conventional over a fair trade chocolatebar in a pre-lab choice. This is captured by a generalized model where intrinsic preferences and the concern for social approval are negatively correlated. %P 1999-11-30 %C Berlin %I DIW Berlin %B Diskussionspapiere / Deutsches Institut für Wirtschaftsforschung ; 1634 %K D03;C91;D12 %K Mikroökonomik;Konsumentenverhalten;Methodenforschung;Experiment;Laborversuche;Private Haushalte und Familien;Ethik %U http://hdl.handle.net/10419/149897 %0 Book %8 25.04.2017 %M 9011991 %T An Integrated Micro Data Base for Tax Analysis in Germany %G Englisch %D 2017 %P 24 S. %Z Sb 89 SOEPpapers %F Mono %F WP %1 DIW2017 %U http://www.diw.de/documents/publikationen/73/diw_01.c.556652.de/diw_sp0902.pdf %+ Stefan Bach, Martin Beznoska, Viktor Steiner %A Bach, Stefan;Beznoska, Martin;Steiner, Viktor;Deutsches Institut für Wirtschaftsforschung, DIW Berlin %X This paper documents methodology underlying the construction of the integrated data base for our study on “Wer trägt die Steuerlast in Deutschland? - Verteilungswirkungen des deutschen Steuer- und Transfersystems” (Who bears the tax burden in Germany? – Distributional Analyses of the German tax and transfer system).

Administrative data like tax records offer more precise information on top incomes, but at the expense of household context details and incomes of non-filers at the bottom of the distribution. We combine the benefits of the two data sources and develop an integrated approach for top-corrected Gini coefficients where we impute top incomes in survey data using information on top income distribution from tax data. We apply our approach to European EU-SILC survey data which in some countries include administrative data. We find higher inequality in those European countries that exclusively rely (Germany, UK) or have relied (Spain) on interviews for the provision of EU-SILC survey data as compared to countries that use administrative data. %P 1999-11-30 %C Berlin %I DIW Berlin %B SOEPpapers on Multidisciplinary Panel Data Research at DIW Berlin ; 895 %K C46;C81;D31;H2 %K Daten SOEP;SOEP Einkommen, Steuern und Soziale Sicherung;SOEP Internationaler Vergleich;SOEP Surveymethodik;Methodenforschung;Private Haushalte und Familien;Einkommensverteilung;Öffentliche Finanzen und Finanzwissenschaft;Vermögensverteilung;Steuer %U http://hdl.handle.net/10419/156166 %0 Book %8 13.02.2017 %M 9011669 %T Transitions in Poverty and Deprivations: An Analysis of Multidimensional Poverty Dynamics %G Englisch %D 2017 %P 34 S. %Z Sb 89 SOEPpapers %F Mono %F WP %1 DIW2017 %U http://www.diw.de/documents/publikationen/73/diw_01.c.552508.de/diw_sp0894.pdf %+ Nicolai Suppa %A Suppa, Nicolai;Deutsches Institut für Wirtschaftsforschung, DIW Berlin %X This paper explores a novel way to analyse poverty dynamics that are specific to certain measures of multidimensional poverty, such as the "adjusted headcount ratio" proposed by Alkire & Foster (2011a). Assuming there is panel data available, I show that a simultaneous and comprehensive account of transitions in deprivations and poverty allows complex interdependencies between dimensions in a dynamic context to be handled and, at the same time, allows for several advanced types of analyses. These analyses include (i) a decomposition of changes in multidimensional poverty, which reveals why poverty decreases or increases; (ii) a framework to examine and understand the relationship between the dashboard approach and dimensional contributions and multidimensional poverty in a dynamic setting; (iii) a presentation of methods that illuminate the process of the accumulation of deprivations. The suggested types of analyses are illustrated using German panel data.

Wir ziehen dieSchlussfolgerung, dass langfristig wirkende Entwicklungen und Gefahren auch weiterhinvorwiegend dem Diskurs der Fachleute und der politisch denkenden „Avantgarde“zugewiesen werden sollten. Undam Ende müssen in einer repräsentativen Demokratie dieParlamente entscheiden. Auf Basis von modernen repräsentativen Erhebungen undBürgerdialogen können Parlamente vermutlich etwas besser entscheiden als ohne dieseInstrumente der Bürgerbeteiligung. Aber auch eine noch so effektive Bürgerbeteiligung kannParlamente nicht ersetzen. %X This paper demonstrates how quality of life can be measured by plain text in a representative survey, the German Socio Economic Panel study (SOEP). Furthermore, the paper shows that problems that are difficult to monitor, especially problems like the state of the European Union, long-term climate change but also the national debt or problems with the quality of consumer goods (like food) and services (like medical treatment), are not issues of particular importance to the majority of people. Developments and risks that are difficult to monitor and only have long-term effects should be left primarily to the discourse conducted by experts and the politically-minded “elites”, the avant garde. And in representative democracies it is ultimately the parliamentarians who must decide. Parliamentarians are likely able to make somewhat better decisions using modern representative surveys and national dialogues than they would be without these instruments of civic participation. Nevertheless, improved civic participation cannot replace parliaments. %P 1999-11-30 %C Berlin %I DIW Berlin %B SOEPpapers on Multidisciplinary Panel Data Research at DIW Berlin ; 893 %K B41;C81;C83;C88;D69;I31;Z13 %K Daten SOEP;SOEP Surveymethodik;SOEP Sonstiges;Methodenforschung;Lebensqualität;Befragung;Panel;Deutschland %U http://hdl.handle.net/10419/155371 %0 Book %8 07.07.2017 %M 9012355 %T The Early Childhood Education and Care Quality in the Socio-Economic Panel (SOEP-ECEC Quality) Study - K2ID-SOEP Data: Forschungsprojekt im Auftrag der Jacobs Foundation %G Englisch %D 2017 %P 54 S. %Z Sb 89 Data Doc. %F Mono %F Sac %1 DIW2017 %U http://www.diw.de/documents/publikationen/73/diw_01.c.561222.de/diw_datadoc_2017-091.pdf %+ Pia S.

Zwei weitere Beiträge erörtern die Möglichkeiten und Limitationen von Forschungsdaten zur gemeinsamen Verteilung von Vermögen und Erbschaften. Der erste Forschungsbeitrag „Longitudinal wealth data and multiple imputation -- An evaluation study“ ist ein Simulationsprojekt, das die bessere Imputation von fehlenden Werten in längsschnittlichen Vermögenssurveys zum Ziel hat. Die univariate Row-and-Column-Imputation schneidet entsprechend der Trend- und Ungleichheitsanalysen gut ab. Ihre Kombination mit MICE als Fallback-Methode hat für alle betrachteten Vermögenskomponenten die Imputationsqualität erhöht. Für Vermögensmobilität zeigt sich auf der anderen Seite, dass ein reiner MICE- Ansatz die bevorzugte Wahl darstellt, da es die in den Originaldatensätzen beobachteten Mobilitätsstrukturen am besten repliziert. Das Kapitel „Estimating top wealth shares using survey data -- An empiricist's guide“ knüpft daran an, da die Behandlung fehlender Werte (Item-Non-Response) noch nicht ausreicht, um der Tatsache Rechnung zu tragen, dass Individuen oder Haushalte komplett die Teilnahme verweigern (Unit-Non-Response). In einer Reihe von Monte-Carlo-Simulationen zeigt dieser Beitrag, dass die Zuschätzung Top-Vermögender durch einen Pareto-simulierten Rand mittels Maximum- Likelihood-Methode sowohl Gesamtvermögen als auch Anteilswerte deutlich unterschätzt. Die Hinzunahme von Daten aus sogenannten Reichenlisten führt zu einer Verbesserung bis hin zur Überschätzung der Vermögensanteile der Top- Vermögenden, obwohl das Gesamtvermögen immer noch unterschätzt wird. Das Kapitel „Breaking down Germany's private wealth into inheritance and personal efforts -- A distributional analysis“ betrachtet die gemeinsame Verteilung von Privatvermögen und erhaltener Vermögenstransfers aus Erbschaften und Schenkungen im neuen Haushaltspanel Private Haushalte und ihre Finanzen zur Berechnung der Bedeutung von Erbschaften entlang der Vermögensverteilung. Es zeigt sich, dass die Vermögensungleichheit für 99 % der Bevölkerung kaum durch Erbschaften zu erklären ist: ihr Anteil am Vermögen liegt bei etwa einem Drittel und ändert sich minimal entlang der Vermögensverteilung. Für Rentner und Pensionäre ist dasselbe Muster zu beobachten. Die Hinzunahme des erwarteten Rentenvermögens reduziert die Bedeutung von Erbschaften vor allem für ärmere Dezile. Der letzte Forschungsbeitrag dieser Dissertation „Comparing the joint distribution of intergenerational transfers, income and wealth across the Euro area“ erweitert die Anwendung aus dem vorangehenden Kapitel um zusätzliche Analysen und stellt die Ergebnisse im europäischen Kontext dar. %X In Germany, a flagrant lack of official register or tax data for scholarly use leads to a situation wherein survey data is the last remaining source of evidence about the distribution of wealth. Two of the four research chapters in this thesis aim to evaluate methods for the improvement of available survey data. The other two contributions discuss the possibilities and limitations of survey data for the analysis of the joint distribution of wealth and wealth transfers. The first research contribution “Longitudinal wealth data and multiple imputation -- An evaluation study” is a simulation exercise that intends to improve the imputation of missing values in wealth surveys. Considering trend and inequality estimates, the univariate row-and-column methods performs surprisingly well. Its combination with MICE as fallback procedure unanimously improves the imputation quality for all asset types considered. However, researchers interested in wealth mobility might prefer the imputation with MICE as basic and fallback, as it best replicates the mobility structures observed in the original data. The chapter “Estimating top wealth shares using survey data -- An empiricist's guide” picks up where the previous one left off: the treatment of missing values (item non-response) is not sufficient if individuals or complete households refuse to participate in a survey (unit non-response). In a series of Monte Carlo experiments this contribution shows that using maximum likelihood techniques to simulate a Pareto distributed top tail does not improve the estimates, as aggregate wealth and shares are still biased downward. The addition of rich list data does improve--and potentially overestimate--top wealth shares, while still yielding aggregate numbers that are too low. The fourth chapter “Breaking down Germany's private wealth into inheritance and personal efforts -- A distributional analysis” takes advantage of the records of both household wealth and wealth transfers received from inheritances and gifts in the questionnaire of the survey Panel on Household Finances, which enables us to compute the significance of inheritance for different quantiles of the distribution of wealth in Germany. We show that wealth inequality, at least for 99 % of the German population, is hardly the result of an unequal distribution of inherited wealth: the ratio is one-third and barely changes along the distribution of wealth. This observation is nigh on identical for the sub population of retirees. The addition of pension wealth reduces the significance of inherited wealth for a household's financial situation particularly in the bottom half of the wealth distribution. The final research contribution “Comparing the joint distribution of intergenerational transfers, income and wealth across the Euro area” expands upon the previous chapter with additional analyses in a European context. %P 1999-11-30 %C Berlin %I Freie Universität %K Methodenforschung;Private Haushalte und Familien;Vermögen;Simulation;Deutschland %0 Book %8 20.02.2017 %M 9011702 %T Essays in Behavioral Economics and Econometrics: Dissertation %G Englisch %D 2017 %P XVI, 137 S. %Z DIWDok %F Mono %F Sac %1 DIW2017 %+ Christian Zankiewicz %A Zankiewicz, Christian %X Der verhaltensökonomischen Literatur entsprechend behandeln die drei Kapitel dieser Dissertation unterschiedliche Aspekte des menschlichen Verhaltens, welches als "nicht-rational" zu bezeichnen ist. Jedes dieser Kapitel leistet einen Beitrag zum aktuellen Stand der Forschung auf dem Gebiet der Verhaltensökonomik mit Hilfe von entweder experimentellen, empirischen oder methodischen Ansätzen. Das erste Kapitel schlägt ein einfaches verhaltensökonomisches Modell vor und unterzieht dieses einer Reihe von experimentellen Tests. Das Modell erweitert die Literatur zur Fehlwahrnehmung von multiplikativen Wachstumsprozessen und hilft somit typische Fehlinvestitionen in der langen Frist zu erklären. Im Rahmen des zweiten Kapitels werden Daten einer Online-Kreditbörse genutzt, um empirisch zu untersuchen, ob sich private Investoren entsprechend den Vorhersagen der standardmäßigen ökonomischen Fachliteratur verhalten und einzig die erwartete Rendite berücksichtigen oder ob sie von anderen nicht-finanztechnischen Attributen eines Schuldners beeinflusst werden. Der Schwerpunkt der Analyse liegt dabei auf Geschlechterdiskriminierung im Rahmen dessen unterschiedliche Diskriminierungskonzepte getestet werden. Das dritte Kapitel wählt einen methodischen Ansatz und schlägt ein innovatives Experiment-Design vor, welches den empirisch gut dokumentierten Schwierigkeiten bzgl. der Angabe von subjektiven Wahrscheinlichkeiten von Teilnehmern an Umfragen und Laborexperimenten Rechnung trägt. Ein Binary-Choice-Ansatz eingebettet in ein adaptives Experiment-Design minimiert den Aufwand für die Befragten und ermöglich somit eine praktikable und effiziente Elizitierung der subjektiven Meinungen. %X In the line with the literature on behavioral economics, the three chapters of this dissertation shed light on different aspects of human behavior that are at odds with rationality. Each chapter contributes to the existing behavioral economic research using either experimental, empirical, or methodological tools. First, by proposing and experimentally testing a simple behavioral model that extends the literature on the misperception of multiplicative growth processes, Chapter 1 aims to explain common money mistakes that people often make with long-term investments such as retirement savings plans. Second, in Chapter 2, real-life investment data of an online-lending platform are used to empirically investigate if private investors behave as the standard economic literature would predict and solely consider an investment’s expected return or if they also care about other non-financial attributes of a debtor. The focus of the analysis is on gender discrimination, thereby defining and econometrically testing different concepts of how investors discriminate between male and female borrowers. Third, Chapter 3 takes a methodological path and proposes a novel experimental design that accounts for the empirically well-documented difficulties that survey respondents typically have when asked to state subjective probabilities. A binary choice approach embedded in an adaptive experimental design helps to minimize effort of the respondents, thus allowing for a more practical belief elicitation in both the lab and the field. %P 1999-11-30 %C Berlin %I Humboldt Univ. %K Methodenforschung;Laborversuche;Experiment;Verteilungstheorie;Verteidigungsökonomik;Entscheidungstheorie %R http://dx.doi.org/10.18452/18364 %U urn:nbn:de:kobv:11-110-18452/19037-8 %0 Journal Article %8 09.03.2017 %M 9011828 %T Structural Vector Autoregressions with Heteroskedasticity: A Review of Different Volatility Models %G Englisch %D 2017 %P S. 2-18 %Z DIWDok %F Aufsatz %F Main %1 DIW2017 %+ Helmut Lütkepohl, Aleksei Netsunajev %A Lütkepohl, Helmut;Netsunajev, Aleksei %X Changes in residual volatility are often used for identifying structural shocks in vector autoregressive (VAR) analysis.

Unfortunately, the approaches currently used for modeling heteroskedasticity all have drawbacks. For instance, assuming known dates for variance changes is often unrealistic while more flexible models based on GARCH or Markov switching residuals are difficult to handle from a statistical and computational point of view. Therefore we propose a model based on a smooth change in variance that is flexible as well as relatively easy to estimate and illustrate its use by analysis of the interaction between monetary policy and the stock market based on a five-dimensional system of U.S. variables. For the benchmark setup it is found that previously used conventional identification schemes in this context are rejected by the data if heteroskedasticity is allowed for. We also illustrate the implications of using different transition variables and varying the sample period. %P 1999-11-30 %V 84 %B Journal of Economic Dynamics & Control %B 84 (2017), S. 43-57 %K C32 %K Methodenforschung;Zeitreihenanalyse;Schock %R https://doi.org/10.1016/j.jedc.2017.09.001 %0 Book Section %8 26.06.2017 %M 9012277 %T An Overview of the SOEP Samples: Fieldwork Report 2016 from Kantar Public %G Englisch %D 2017 %P S. 28-36 %Z Sb 89 SOEP Wave %F Aufsatz %F AufSam %1 DIW2017 %+ Simon Huber %A Huber, Simon %P 1999-11-30 %B SOEP Wave Report 2016 %C Berlin: DIW Berlin %D 2017 %K SOEP;Daten SOEP;Methode;Methodenforschung %0 Book Section %8 26.06.2017 %M 9012284 %T SOEP-Related Study: BRISE %G Englisch %D 2017 %P S. 73-74 %Z Sb 89 SOEP Wave %F Aufsatz %F AufSam %1 DIW2017 %+ Hannes Kröger %A Kröger, Hannes %P 1999-11-30 %B SOEP Wave Report 2016 %C Berlin: DIW Berlin %D 2017 %K SOEP;Daten SOEP;Methode;Methodenforschung %0 Book Section %8 06.10.2017 %M 9012724 %T General Introduction and Overview of Available Datasets %G Englisch %D 2017 %Z Sb 89 SOEP SP %F Aufsatz %F AufSam %1 DIW2017 %+ Jan Goebel %A Goebel, Jan %P 1999-11-30 %B SOEP-Core v32 – Documentation on Biography and Life History Data %C Berlin: DIW Berlin %D 2017 %K Methodenforschung %0 Book Section %8 06.10.2017 %M 9012729 %T The Couple History Files BIOCOUPLM and BIOCOUPLY, and Marital History Files BIOMARSM and BIOMARSY %G Englisch %D 2017 %P S. 97-115 %Z Sb 89 SOEP SP %F Aufsatz %F AufSam %1 DIW2017 %+ Maik Hamjediers, Paul Schmelzer %A Hamjediers, Maik;Schmelzer, Paul %P 1999-11-30 %B SOEP-Core v32 – Documentation on Biography and Life History Data %C Berlin: DIW Berlin %D 2017 %K Methodenforschung;Daten SOEP %0 Book Section %8 06.10.2017 %M 9012733 %T BIOAGE01, BIOAGE03, BIOAGE06, BIOAGE08, BIOAGE10, BIOAGE12: Generated Variables from The "Mother & Child", "Parent", And "Pupils" Questionnaires %G Englisch %D 2017 %P S. 140-148 %Z Sb 89 SOEP SP %F Aufsatz %F AufSam %1 DIW2017 %+ David Richter %A Richter, David %P 1999-11-30 %B SOEP-Core v32 – Documentation on Biography and Life History Data %C Berlin: DIW Berlin %D 2017 %K Methodenforschung;Daten SOEP %0 Book Section %8 06.10.2017 %M 9012737 %T BIOIMMIG: Generated and Status Variables from SOEP for Foreigners and Migrants %G Englisch %D 2017 %P S. 213-268 %Z Sb 89 SOEP SP %F Aufsatz %F AufSam %1 DIW2017 %+ Jan Goebel and Katharina Strauch %A Goebel, Jan;Strauch, Katharina %P 1999-11-30 %B SOEP-Core v32 – Documentation on Biography and Life History Data %C Berlin: DIW Berlin %D 2017 %K Methodenforschung;Daten SOEP %0 Newspaper Article %8 10.10.2017 %M 9012761 %T Statement: Richard Thaler ist ein würdiger Gewinner des Nobelpreises für Ökonomie %G Deutsch %D 2017 %P [Online-Artikel] %Z DIWDok %F Aufsatz %F AufTwz %1 DIW2017 %+ Marcel Fratzscher %A Fratzscher, Marcel %N 09.10.2017 09.10.2017 %P 2017-10-09 %B BerlinOeconomicus %B (09.10.2017), [Online-Artikel] %K Methodenforschung;Verhaltensforschung;Verhaltensökonomik %0 Journal Article %8 13.12.2017 %M 9013063 %T Analyzing the Continuity of Attitudinal and Perceptual Indicators in Hybrid Choice Models %G Englisch %D 2017 %P S. 28-39 %Z DIWDok %F Aufsatz %F RefSSCI %1 DIW2017 %+ Francisco J. Bahamonde-Birke, Juan de Dios Ortúzar %A Bahamonde Birke, Francisco J.;Ortúzar, Juan de Dios %X The main objective of this paper is to compare the consequences of treating the attitudinal and perceptual indicators of hybrid discrete choice (HDC) models as continuous or ordinal outcomes. Based on tradition and computational reasons, such indicators are still predominantly treated as continuous outcomes in practice. This usually neglects their nature (as respondents are normally asked to state their preferences, or level of agreement with a set of statements, using a discrete scale) and may induce bias.We conducted an analysis based on simulated data and real information (two case studies) and were able to find that the distribution of the indicators (especially when associated with non-uniformly spaced thresholds) may lead to a clear deterioration of the model’s overall predictive capacity, when assuming continuous indicators. This, however, does not translate to the goodness-of-fit of the discrete-choice component of the HDC model. Along the same line, a higher relative variability of the latent variables increases the differences between both approaches (ordinal and continuous outcomes), especially concerning the goodness-of-fit of the discrete-choice component of the model. It was not possible to identify a relation between the predictive capacity of both approaches and the amount of available information. Considering more indicators tend to reduce the gap between both approaches, but the effect is significantly smaller than the effect of the relative variability.Finally, two case studies using real data confirmed that no major differences, regarding the predictability of the discrete choices can be observed when the relative variability of the latent variables is low. Thus, we recommend analyzing this relative variability in order to decide on the suitability of the continuous assumption as a suitable alternative to the more onerous but correct ordinal treatment. %P 1999-11-30 %V 25 %B Journal of Choice Modelling %B 25 (2017), S. 28-39 %K Entscheidungstheorie;Methodenforschung %R https://doi.org/10.1016/j.jocm.2017.01.003 %0 Journal Article %8 08.02.2017 %M 9011650 %T The PIAAC Longitudinal Study in Germany: Rationale and Design %G Englisch %D 2017 %P 11 S. %Z DIWDok %F Aufsatz %F RefSSCI %1 DIW2017 %+ Beatrice Rammstedt, Silke Martin, Anouk Zabal, Claus Carstensen, Jürgen Schupp %A Rammstedt, Beatrice;Martin, Silke;Zabal, Anouk;Carstensen, Claus;Schupp, Jürgen %X In Germany, the respondents who had participated in the 2012 survey of the Programme for the International Assessment of Adult Competencies (PIAAC) were re-approached for the panel study PIAAC-L.

Greater diversification across risk measures is conducive to closing this knowledge gap. What we find is that performance increases considerably if we combine single-item risk measures to form multiple-item risk measures. Results are improved the more single-item measures they contain, and also if these single-item risk measures use different elicitation methods. Interestingly, survey items perform just as well as incentivized experimental items in explaining risky behavior. %P 1999-11-30 %V 59 %B Journal of Economic Psychology %B 59 (2017), S. 59-86 %K D81;C93;O12 %K Methodenforschung;Entscheidung;Risiko;Feldforschung;Mikroökonomik %R http://dx.doi.org/10.1016/j.joep.2017.02.005 %0 Journal Article %8 19.05.2017 %M 9012119 %T Revisiting the Evidence for Cardinal Treatment of Ordinal Variables %G Englisch %D 2017 %P S. 337-358 %Z DIWDok %F Aufsatz %F RefSSCI %1 DIW2017 %+ Carsten Schröder, Shlomo Yitzhaki %A Schröder, Carsten;Yitzhaki, Shlomo %X Well-being (life satisfaction or happiness) is a latent variable that is impossible to observe directly. Moreover, it does not have a unit of measurement. Hence, survey questionnaires usually ask people to rate their well-being in different domains. The common practice of comparing well-being by means of averages or linear regressions ignores the fact that well-being is an ordinal variable. Since data is ordinal, monotonic increasing transformations are permissible. We illustrate the sensitivity of empirical studies to monotonic transformations using examples that relate to well-known empirical papers, and provide two theoretical conditions that enable us to rank ordinal variables. In our examples, monotonic increasing transformations can in fact reverse the conclusion reached. %P 1999-11-30 %V 92 %B European Economic Review %B 92 (2017), S. 337-358 %K C18;C23;C25;I30;I31;I39 %K Soziales und Gesundheit;Methodenforschung;Methode;Lebenszufriedenheit;Panel %R https://doi.org/10.1016/j.euroecorev.2016.12.011 %0 Book Section %8 26.06.2017 %M 9012278 %T The SOEP Screening Samples (L2/3): 2016 Fieldwork Report from Kantar Public %G Englisch %D 2017 %P S. 37-40 %Z Sb 89 SOEP Wave %F Aufsatz %F AufSam %1 DIW2017 %+ Simon Huber %A Huber, Simon %P 1999-11-30 %B SOEP Wave Report 2016 %C Berlin: DIW Berlin %D 2017 %K SOEP;Daten SOEP;Methode;Methodenforschung %0 Book Section %8 26.06.2017 %M 9012285 %T The SOEP Metadata Documentation System: paneldata.org %G Englisch %D 2017 %P S. 75-77 %Z Sb 89 SOEP Wave %F Aufsatz %F AufSam %1 DIW2017 %+ Marcel Hebing, Jan Goebel %A Hebing, Marcel;Goebel, Jan %P 1999-11-30 %B SOEP Wave Report 2016 %C Berlin: DIW Berlin %D 2017 %K SOEP;Daten SOEP;Methode;Methodenforschung %0 Journal Article %8 30.06.2017 %M 9012323 %T A Reputation Economy: How Individual Reward Considerations Trump Systemic Arguments for Open Access to Data %G Englisch %D 2017 %P S. 1-10 %Z DIWDok %F Aufsatz %F RefSCI %1 DIW2017 %+ Benedikt Fecher, Sascha Friesike, Marcel Hebing, Stephanie Linek %A Fecher, Benedikt;Friesike, Sascha;Hebing, Marcel;Linek, Stephanie %X Open access to research data has been described as a driver of innovation and a potential cure for the reproducibility crisis in many academic fields. Against this backdrop, policy makers are increasingly advocating for making research data and supporting material openly available online. Despite its potential to further scientific progress, widespread data sharing in small science is still an ideal practised in moderation. In this article, we explore the question of what drives open access to research data using a survey among 1564 mainly German researchers across all disciplines. We show that, regardless of their disciplinary background, researchers recognize the benefits of open access to research data for both their own research and scientific progress as a whole. Nonetheless, most researchers share their data only selectively. We show that individual reward considerations conflict with widespread data sharing. Based on our results, we present policy implications that are in line with both individual reward considerations and scientific progress. %P 1999-11-30 %V 3 %B Palgrave Communications %B 3 (2017), 17051, S. 1-10 %K Methodenforschung;Forschungsdaten;Open Access;Open Source;Wissenschaftler;Forschung und Entwicklung %R http://dx.doi.org/10.1057/palcomms.2017.51 %0 Book Section %8 06.10.2017 %M 9012726 %T MIGSPELL: The Migration-Biography (Samples M1 and M2): Integrated Version: Waves bd to bf %G Englisch %D 2017 %Z Sb 89 SOEP SP %F Aufsatz %F AufSam %1 DIW2017 %+ Klaudia Erhardt %A Erhardt, Klaudia %P 1999-11-30 %B SOEP-Core v32 – Documentation on Biography and Life History Data %C Berlin: DIW Berlin %D 2017 %K Methodenforschung;Daten SOEP %0 Book Section %8 06.10.2017 %M 9012730 %T BIOBIRTH: A Data Set on the Birth Biography of Female Respondents %G Englisch %D 2017 %P S. 116-127 %Z Sb 89 SOEP SP %F Aufsatz %F AufSam %1 DIW2017 %+ Christian Schmitt %A Schmitt, Christian %P 1999-11-30 %B SOEP-Core v32 – Documentation on Biography and Life History Data %C Berlin: DIW Berlin %D 2017 %K Methodenforschung %0 Book Section %8 06.10.2017 %M 9012734 %T BIOAGE17: The Youth Questionnaire %G Englisch %D 2017 %P S. 149-160 %Z Sb 89 SOEP SP %F Aufsatz %F AufSam %1 DIW2017 %+ Marco Giesselmann, Mila Staneva, Tabea Naujoks %A Giesselmann, Marco;Staneva, Mila;Naujoks, Tabea %P 1999-11-30 %B SOEP-Core v32 – Documentation on Biography and Life History Data %C Berlin: DIW Berlin %D 2017 %K Methodenforschung;Daten SOEP %0 Book Section %8 06.10.2017 %M 9012738 %T BIORESID: Variables on Occupancy and Second Residence %G Englisch %D 2017 %P S. 269-273 %Z Sb 89 SOEP SP %F Aufsatz %F AufSam %1 DIW2017 %+ Marco Giesselmann, Mila Staneva,Tabea Naujoks %A Giesselmann, Marco;Staneva, Mila;Naujoks, Tabea %P 1999-11-30 %B SOEP-Core v32 – Documentation on Biography and Life History Data %C Berlin: DIW Berlin %D 2017 %K Methodenforschung;Daten SOEP %0 Journal Article %8 12.03.2018 %M 9013439 %T If You Choose Not to Decide, You Still Have Made a Choice %G Englisch %D 2017 %P S. 13-23 %Z DIWDok %F Aufsatz %F RefSSCI %1 DIW2007 %+ Francisco J.

By doing this, the modeller avoids adding white noise to the data and may gain additional information. This paper proposes a framework to model discrete choices in the presence of indifference alternatives. The approach allows depicting the likelihood function, independent of the number of alternatives in the choice-set and in the subset of indifference alternatives, offering a new approach to existing methods that are only defined for binary choice situations. The method is tested with the help of simulated and real data observing that the proposed framework allows recovering the parameters used in the generation of the synthetic datasets without major difficulties in most cases. Alternative approaches, such as considering the indifference option as an opt-out alternative or ignoring the indifference choices are clearly outperformed by the proposed framework and appear not capable of recovering parameters in the simulated set. %P 1999-11-30 %V 22 %B Journal of Choice Modelling %B 22 (2017), S. 13-23 %K Methodenforschung;Private Haushalte und Familien;Entscheidung;Entscheidungstheorie %R https://doi.org/10.1016/j.jocm.2016.11.002 %0 Book Section %8 15.01.2019 %M 9014766 %T Towards OSGeo Best Practices for Scientific Software Citation: Integration Options for Persistent Identifiers in OSGeo Project Repositories %G Englisch %D 2017 %P S. 134-145 %Z DIWDok %F Aufsatz %F AufSam %1 DIW2017 %+ Peter Löwe, Markus Neteler, Jan Goebel, Marco Tullney %A Löwe, Peter;Neteler, Markus;Goebel, Jan;Tullney, Marco %X As a contribution to the currently ongoing larger effort to establish Open Science as best practices in academia, this article focuses on the Open Source and Open Access tiers of the Open Science triad and community software projects. The current situation of research software development and the need to recognize it as a significant contribution to science is introduced in relation to Open Science. The adoption of the Open Science paradigms occurs at different speeds and on different levels within the various fields of science and crosscutting software communities. This is paralleled by the emerging of an underlying futuresafe technical infrastructure based on open standards to enable proper recognition for published articles, data, and software. Currently the number of journal publications about research software remains low in comparison to the amount of research code published on various software repositories in the WWW. Because common standards for the citation of software projects (containers) and versions of software are lacking, the FORCE11 group and the CodeMeta project recommending to establish Persistent Identifiers (PIDs), together with suitable metadata setss to reliably cite research software. This approach is compared to the best practices implemented by the OSGeo Foundation for geospatial community software projects. For GRASS GIS, a OSGeo project and oneof the oldest geospatial open source community projects, the external requirements for DOI-based software citation are compared with the projects software documentation standards. Based on this status assessment, application scenarios are derived, how OSGeo projects can approach DOI-based software citation, both as a standalone option and also as a means to foster open access journal publications as part of reproducible Open Science. %P 1999-11-30 %B FOSS4G 2017 Full Conference Proceedings ( Papers and Posters), Boston, USA %C Boston %D 2017 %K Open Source;Geographie;Methodenforschung;Software %R https://doi.org/10.5281/zenodo.1034878 %0 Book %8 10.05.2017 %M 9012059 %T Weighting in PIAAC-L 2014 %G Englisch %D 2017 %P 21 S. %Z DIWDok %F Mono %F WP %1 DIW2017 %+ Simone Bartsch, Katharina Poschmann, Luise Burkhardt %A Bartsch, Simone;Poschmann, Katharina;Burkhardt, Luise;GESIS - Leibniz-Institut für Sozialwissenschaften %N 2017/06 2017/06 %P 1999-11-30 %C Köln %I GESIS %B GESIS-Papers ; 06 %K Methodenforschung;Befragung;Panel %0 Book %8 29.01.2018 %M 9013238 %T Weighting in PIAAC-L 2015 %G Englisch %D 2017 %P 22 S. %Z DIWDok %F Mono %F WP %1 DIW2017 %+ Luise Burkhardt, Simone Bartsch %A Burkhardt, Luise;Bartsch, Simone;GESIS - Leibniz-Institut für Sozialwissenschaften %N 300 300 %P 1999-11-30 %C Köln %I GESIS %B GESIS-Papers ; 30 %K Methodenforschung;Befragung;Panel %U http://nbn-resolving.de/urn:nbn:de:0168-ssoar-50569-5
