SOEP Brown Bag Seminar The Long-Term Effects of World War II Destruction on Private Wealth in Germany

The physical destructions, expropriations, resettlements, and interruptions of international trade during Second World War caused a sharp reduction of wealth levels and inequality in many countries (Piketty, 2014). In Germany, an estimated 20 percent of the West German housing stock was destroyed. This paper assesses whether the effects of this destruction are measurable in the German wealth distribution today using unique data on the destruction of 1739 West German cities linked with recent micro data on household wealth portfolios provided by the Socio-economic Panel. For persons born in cities or villages that were more badly damaged then, wealth is still significantly lower today. Similarly, destruction of parents' cities or villages of birth has significant negative effects on the wealth of their children.  These detrimental effects on wealth holdings today are robust after controlling for a rich set of pre-war regional and city-level control variables.

Arbeitsleben, Familie und Wohlbefinden - Wie wirkt sich die Pandemie auf unsere Gesellschaft aus?

Wie verändert die Coronakrise unseren Alltag? Und wie wirkt sich die Pandemie auf Einzelne und die Gesellschaft aus? Antworten auf diese Fragen findet die Studie „Sozio-ökonomische Faktoren und Folgen der Verbreitung des Coronavirus in Deutschland (SOEP-CoV)“, ein Verbundprojekt zwischen dem Sozio-oekonomischen Panel (SOEP) am DIW Berlin und der Universität Bielefeld. Für SOEP-CoV wurden seit April 2020 mehr als 10.000 Personen telefonisch interviewt.

Im Webinar werden die Auswirkungen der Corona-Pandemie und der zu ihrer Eindämmung beschlossenen Maßnahmen vorgestellt. Darüber hinaus werden aktuelle Ergebnisse zu Veränderungen in der Arbeitssituation, im familiären Zusammenleben sowie im subjektiven Wohlbefinden präsentiert.

Cluster-Seminar Öffentliche Finanzen und Lebenslagen The Effect of Retirement on Health - Evidence from Administrative Data

We combine unique data that include all practitioner health diagnoses based on the International Classification of Diseases (ICD-10) collected from all publicly insured individuals in Germany with a sizable cohort specific pension reform to study the causal effect of an increase in the retirement age on health. For the analysis, we use a cohort specific regression discontinuity design. The data allow us to quantify the causal effect of a raise in the retirement age on specific objective health outcomes, which enables us to disentangle the health effects of along different health dimensions. Broad or subjective outcomes, as mostly used in the literature so far, might aggregate and disguise negative and positive implications for different health dimensions. Our results suggest negative effects of an increase in the early retirement age on mental health and some musculoskeletal diagnoses. We do not find effects for metabolic/nutritional and  heart/circulatory diagnoses as well as health care consumption.

SOEP Brown Bag Seminar Does Unemployment Make Better Fathers? The Effect of Job Loss on Fathers’ Time Investment in the Household

Commonly described as the “gender care gap“, there is a persistent gender difference in the division of child care and housework responsibilities within households in most developed countries. Existing literature on paternal child care involvement and parental leave take-up largely suffers from sample size and selection issues. This paper provides evidence on the effect of an exogenous shock on paternal availability, through a negative employment shock, on the allocation of domestic work within couples. We find that paternal child care and housework significantly increase in the short-run on regular weekdays, while we do not see any similar shifts on Sundays. Effects are positive and persistent for fathers who remain unemployed or have a working partner. Employed mothers react by reducing their time allocated to domestic work, while not employed mothers even increase their time investments. The findings are consistent with theories about time availability as well as relative bargaining power within households.

DIW Applied Micro Seminar Local News, UGC and Professionals: Evidence from Citizen Journalism

Abstract:  User generated content is increasingly substituting content created by professionals. Local news that is generated by citizen journalists could be a promising way of supporting the struggling newspaper industry by reducing costs for professional journalists. We study a network of 122 local Austrian newspapers operating a hybrid model of citizen and professional journalism. We first observe that citizens cover different topics, write shorter articles, and create less engagement. We then exploit a change in the platform’s social recognition system to show that non-monetary incentives drive the production of citizen content, especially for contributors with more experience. We also find that amateur content acts as a substitute for content produced by inexperienced professionals. We finally see that the incentive and substitution effects are more pronounced in smaller regions and for soft news.

Joint with Pedro Ferreira and Ananya Sen.

SOEP Brown Bag Seminar Temporary employment and the midlife nadir in human well-being

Temporary employees rank lower than permanent employees on various measures of mental and physical health, including well-being. Furthermore, much research has indicated an approximate U-shape pattern between age and well-being with a nadir in midlife. Temporary employment may well have different associations with well-being across the lifespan, likely harming people in midlife more than at the start of their working life. Using over twenty years of the German Socio-economic panel (SOEP), this investigation considers the relationship between temporary employment, age and well-being. The results show that temporary employment deepens the U-shape in midlife, and that this result holds when typical socioeconomic factors as well as the industry, region, cohort, personality, employment security and job worries are taken into account.

SOEP Brown Bag Seminar Barriers to humanitarian migration, traumatic events and integration outcomes: Evidence from Germany

In this study we estimate the hidden cost of restrictive migration policies and highlight the need for health-related support among refugees. The traumatic events asylum seekers experience at origin due to exposure to violent conflict and during the journey to the EU may have lasting negative effects on their economic and social integration in the destination country. We hypothesize that the mechanism at play is a relative decline in mental well-being caused by these events. To test our hypothesis, we combine information on the intensity of conflict at countries of origin from the Uppsala Conflict Data Program with the IAB-BAMF-SOEP refugee survey that includes detailed information on experiences of asylum seekers' journey (e.g. victimization), pre-migration refugee characteristics and post-migration integration outcomes (e.g. educational attainment, social behaviour). We also utilise German employment biography data linked to survey respondents to analyse the short- and medium-term labour market implications of these traumatic events. Please note that this project is in a very early stage.

DIW Applied Micro Seminar What do we want? And when do we want it? Alternative objectives and their implications for experimental design.

Summary:  This talk will provide a survey of several papers on the theory and practice of experimental design. I will compare different objectives (estimator precision, outcomes of participants, informing policy choice to maximize average outcomes, and informing policy choice to maximize utilitarian welfare), and their implications for experimental design. I will consider heuristic algorithms, will prove approximate optimality results for some of these algorithms, and will discuss several empirical applications.

SOEP Brown Bag Seminar Wrangling and working with 3D-Building Models

The Federal Agency for Cartography and Geodesy (BKG) provides 3D-Building models for Germany. The data come in a City-GML (geographical markup language) format, locating every building throughout Germany and providing information such as its ground plan, height, and the building’s purpose. I will provide an overview on the data, its coverage and limitations, as they are available for everyone within the DIW. Because of the data format, reading the data is not trivial. Thanks to the Research Infrastructure Department and their help; we are able to access the data in a convenient way. I will present first ideas for research using this data in the context of small area estimation and weighting.

Cluster-Seminar Öffentliche Finanzen und Lebenslagen Decomposition of Gender Pension Gaps Across Europe from a life-course perspective – preliminary drafts from sequence data analysis and Blinder-Oaxaca-Decompositions

My master thesis compares the impact of different life-courses on the Gender Pension Gaps across East and West Germany, Czechia and Italy. Using retrospective data on the dimensions of work and family from SHARELIFE, I contrast two different approaches. The first applies sequence data analysis to identify work-family life course patterns across all four countries as a first step, and includes these life course categories as determinants in a Blinder-Oaxaca-Decomposition of the Gender Pension Gaps. For the second approach, I include the life course variables for work and family indicators separately in the decomposition analysis. My initial results show clear differences in the share of the gap explained by differences in life courses between men and women across countries, highlighting the impact of the different pension systems in the countries. The results differ further across both modelling approaches, revealing the different benefits of both.

SOEP Brown Bag Seminar Welche Fakten braucht die Gesellschaft eigentlich?

Sind Daten das neue Gold? Man hat den Eindruck, dass wir alle technischen Finessen ausloten, um an das wertvolle Gut heranzukommen. Was auch immer mit dem Begriff „Daten“ assoziiert wird, scheint diesem Vorhaben Glanz zu verleihen. Entscheidungen, Politik, Management und vieles mehr sollten jetzt „datengesteuert“ sein. Big Data, Machine Learning, Algorithmen und künstliche Intelligenz versprechen Lösungen für Probleme, die bisher ohne großen Erfolg behandelt wurden. Traditionelle Methoden der Wissensgenerierung durch mühsames, kostenintensives und zeitaufwändiges Sammeln von Daten erscheinen in diesem Licht veraltet und überflüssig. Das Etikett "Data for Policy" (D4P) eignet sich jedoch nur bedingt zur Charakterisierung des Beziehungsgeflechts und der gegenseitigen Beeinflussung von Daten einerseits und Politik andererseits. Auch wenn die Datenmenge im Zeitalter der Digitalisierung und Globalisierung enorm wächst, ist dieser Datenrohstoff nicht direkt für die Behandlung politischer Themen nutzbar. Vielmehr sind geeignete Verfahren erforderlich, um aus der Flut der Rohdaten die wertvollen Inhalte zu verdaubaren Informationen zu destillieren, zu verfeinern und zu kommunizieren. Der Begriff "Fakten" wird hier als Oberbegriff für solche Informationen verwendet. Wenn Daten am Anfang der Verarbeitung stehen, befinden sich die Fakten an dessen Ende. Wie können wir relevante, verifizierte Fakten für jedermann bereitstellen?

DIW Applied Micro Seminar Optimal Benefit-Based Corporate Income Tax

Abstract:   I derive an optimal benefit-based corporate tax rate formula as a function of the public input elasticity of profits and the (net of) tax elasticity of profits. I argue that the existence of the corporate income tax should be justified by the benefit-based view of taxation: firms should pay tax according to the benefits they receive from the use of the public input. I argue that benefit-based corporate taxation is normatively fair. Since the public input is a location-specific factor, a positive benefit-based corporate tax rate is also feasible even in a small open economy. The benefit-based view gives three clear principles of corporate tax design. First, we should tax corporate profits at source. Second, the optimal tax base is location-specific rents. Third, profit shifting is normatively wrong. An empirical application of the formula suggests the optimal benefit-based corporate tax rate on public corporations in the United States lies in the range of 35 to 59 percent.

SOEP Brown Bag Seminar Prosociality and Risk Preferences in the Financial Sector

Using large-scale data from the German Socio-Economic Panel (SOEP), this paper finds that financial professionals have a lower prosociality and riskier behavior than a control group. I interpret these findings using the person-organization fit theory, and thus, the compatibility between the employee's personality and the prevailing culture in their organization. The financial sector attracts rather than socializes riskier and less prosocial professionals. These attitudes are associated with behavioral consequences, and are mainly driven by male professionals in lower management.

Cluster-Seminar Öffentliche Finanzen und Lebenslagen Refugees and the resident populations' mental health

We estimate the effect of a sudden increase in the inflow of refugees on the native population’s mental health in Germany and Swiss. To identify the effect of the sudden influx of refugees to Germany and Swiss, we exploit the quasi-random allocation of the number of refugees to counties in Germany and Swiss. For Germany, we make use of the Socio-Economic Panel. For Swiss, we use individual level data of a large health insurance. Our preliminary results indicate that the sudden increase in the number of refugees increases the individuals’ worries about immigration to Germany but does not change the native population’s mental health in Germany or Swiss.

SOEP Brown Bag Seminar Self-Control: Determinants, Life Outcomes and Intergenerational Implications

This paper studies self-control in a nationally representative sample. Using the wellestablished Tangney scale to measure trait self-control, we find that people’s age as well as the political and economic institutions they are exposed to have an economically meaningful impact on their level of self-control. A higher degree of self-control is, in turn, associated with better health, educational and labor market outcomes as well as greater financial and overall well-being. Parents’ self-control is linked to reduced behavioral problems among their children. Importantly, we demonstrate that self-control is a key behavioral economic construct which adds significant explanatory power beyond other more commonly studied personality traits and economic preference parameters. Our results suggest that self-control is potentially a good target for intervention policies.

Berlin Lunchtime Meeting Making a nation-wide randomized field experiment: Lessons from the Finnish basic income trial

The original goal of the Finnish experiment of 2017 and 2018 was to try to get some evidence on how a new social policy instrument mimicking a basic income would work and what kind of behavioral consequences it would have. The realized experiment was restricted to people aged 25–58 already receiving a labor market subsidy or unemployment allowance and a total of 2,000 participants were randomly selected to receive a basic income payment of €560 per month.

SOEP Brown Bag Seminar Using Mathematical Graphs for Questionnaire Validation

We present an approach for studying three quality issues related to survey data, namely the detection of interviewer misbehaviour, the correct implementation of the questionnaire programming and possible redundant paths, which lead to case numbers hindering feasible statistical analysis. The idea is using a theoretical graph model for describing all possible paths through a survey questionnaire. The vertices of the questionnaire graphsrepresent questions and the edges the paths linking the questions. So, we are able to derive properties of the questionnaire by studying its graph. These properties are all traversed paths through the questionnaire and all possible data patterns resulting through filtering. Examining the properties gives first hints if there are peculiarities, which we need to examine in more detail. To study potential interviewer misbehavior, we test if the mean number of follow-up questions of interviewers is significantly smaller than the overall mean number of follow-up questions of all interviewers. To examine path redundancy and the questionnaire programming we test, if the path frequencies fall below a pre-specified value and compare the vertices and edges of the theoretical and empirical graph, respectively. To study the capability of our approach, we designed a small case study and applied it to NEPS data.

Cluster-Seminar Öffentliche Finanzen und Lebenslagen A firm-side perspective on parental leave

A large literature documents effects of parental leave on mothers' labour market outcomes, yet we know very little about the effects on their  firms and co-workers. We use unique administrative data that covers the universe of employees subject to social security and firms in Germany to address this question. We first establish some novel stylised facts in parental leave-taking  with respect to firm characteristics and worker substitutability: Mothers take longer leave periods  the more internal and  external substitutes are available. We then use an exogenous and substantial increase in  paid parental leave entitlements to study how longer leave absences by mothers causally affect the short- and long-run employment outcomes of mothers and their co-workers, as well as  firm productivity, worker turnover, and closures. For identification, we exploit the 2007-parental leave reform that introduced an earnings-related parental leave payment scheme and that reduced employment particularly among high-earning women in the first year after childbirth. Our findings provide important insights into the firm-side effects of  parental leave absences  and help reconcile why longer parental leave breaks have a negligible or even positive effect on maternal labour market outcomes in the long-run.
