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

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.

    DIW Applied Micro Seminar Household Finance 0.5 or 2.0? Eliciting Individuals’ Financial Decision-Making Approaches (cancelled)

    Abstract:   How exactly do individuals approach financial decisions? Do they apply sophisticated formulas, back of the envelope math, do they guess or something else? We show that literally asking individuals to explain their approaches generates new insights about those questions that are reliable and have predictive power out of sample. We find, for example, that when assessing the value of an annuity 40% of individuals use some math with some using formulas similar to actuaries; the other 60% apply guessing strategies. Valuation approaches predict valuation results, valuation precision, and behavioral reaction to a priming intervention designed to match one approach discovered. Our method opens new pathways to understanding financial decision making as well as designing effective policy interventions.

    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.

    SOEP Brown Bag Seminar From workers to capitalists in less than two generations: A study of Chinese urban elite transformation between 1988 and 2013

    Economic and social transformation of China during the past 40 years is without precedent in human history. While the economic transformation was extensively studied, social transformation was not. In this paper, we use for the first time harmonized household surveys covering the period 1988-2013 to study the changes in the characteristics of the richest 5 percent of China’s urban population. We find that the elite changed from being composed of high government officials, clerical staff, and workers in 1988 to professionals and small and large business owners in 2013. The educational level of the elite increased substantially. Membership in CCP has a positive (albeit small) effect on one’s income but is particularly valuable to large business owners.

    DIW Applied Micro Seminar Knowledge Spillover and Individual Careers

    Abstract: Through social interaction in the workplace, coworkers are likely to learn from each other (knowledge spillover) and this may extend the returns to firm-provided training from trained workers onto untrained coworkers. Based on German matched-employer employee data covering the universe of employees we investigate whether unskilled workers derive long-term career benefits if they were exposed during their first job to high-quality apprenticeship graduates in the same workplace. After controlling for a large range of confounding factors, we find evidence for positive long-run effects, which hold after leaving the initial firm and conditional on the quality of future peers. Moreover, effects are up to three times larger if the initial occupation has high skill content and task complexity. Overall, analysis suggests that there are positive external effects of apprenticeship training programmes via knowledge spillover onto unskilled coworkers.

    Cluster-Seminar Öffentliche Finanzen und Lebenslagen The effect of xenophobic attacks on refugees’ mental health

    The high prevalence of forced migration in recent years has induced a shift in attitudes towards immigrants and refugees and, in turn, increasing xenophobic violence. We address this topic and estimate the effect of xenophobic attacks against refugee shelters on refugees’ mental health. For this purpose, we combine two innovative data sets: administrative records on xenophobic crime by the Federal Criminal Office and the IAB-BAMF-SOEP Survey of Refugees. Considering that the interview date is orthogonal to a hate crime taking place, we use a regression discontinuity design to identify the local causal effect. Our results indicate that hate crime has a substantial negative effect on mental health indicators, including the Mental Component Summary Score and the Patient Health Questionnaire-4. Furthermore, we show that the stock of country-specific human capital moderates the effect.

    Cluster-Seminar Öffentliche Finanzen und Lebenslagen A question of gender: How promotions affect earnings

    Occupational positions can explain an important part of the differences in pay between men and women. However, a considerable Gender Pay Gap exists even within the same occupational position. In this paper, we aim at understanding the reason for the gap within occupational positions and, therefore, investigate whether promotions lead to the same effect on earnings growth for men and women. Using unique data on the total population of all employees subject to social security, we are the first to estimate the gender gap in earnings growth after promotions in Germany. Our first results emphasize that women’s earnings growth is lower than men’s after being promoted within the same position. This effect cannot be explained by motherhood as this holds also true for childless women. However, the effect disappears when we add firm-fixed effects. This finding suggest that women select into firms where promotions lead to lower earnings growth.

    InGRID-2 Expert Workshop 'Comparative Analysis of Longitudinal Data on Educational Outcomes’

    Educational outcomes are crucial for social participation and labor market opportunities. To develop strategies to improve people’s social and economic prospects, governments are increasingly interested in international comparisons of educational opportunities and outcomes. The workshop ‘Comparative Analysis of Longitudinal Data on Educational Outcomes’ aims to describe and discuss educational transitions and outcomes in Europe across the life course. To evaluate educational outcomes in different educational systems, this workshop focuses on the use of various longitudinal datasets, which are key in going beyond merely descriptive approaches and getting closer to causal analysis. Contributions with a focus on comparability of longitudinal datasets, statistical methods for harmonizing longitudinal datasets, and comparative analysis of longitudinal educational trajectories are especially welcome.

    This expert workshop is targeted at experienced researchers. It is also open to other academics, policy professionals, and data users, and will provide participants with opportunities to discuss their projects and to network with international experts and colleagues in the field.

    SOEP Brown Bag Seminar Determinants of Locus of Control - Evidence from a Mentoring Intervention

    (together with Fabian Kosse and Armin Falk)
    In this project we investigate the determinants of locus of control using data from the BRIQ Family Panel. Particular interest lies in the effectiveness of a one year mentoring intervention which targeted low SES children at the age of 7 to 9.
    We find that the mentoring intervention had no effect on locus of control in the first 5 waves after the intervention. Small effects begin to show 6 years after the intervention. They are however not very robust. In contrast, bonding is found to have the strongest effect on locus of control, independent of current parenting styles. This may point to the importance of early childhood in setting the grounds for internal generalized control expecatations.
    I am happy to discuss these preliminary resuls with you and look forward to your comments and feedback.
