    Cluster-Seminar Public Finances and Living Conditions The Effects of Fees on Study Duration and Completion in the Population of German Students

    This paper exploits unexpected regional changes in fees to uncover the causal effect on the duration of study and completion probabilities for an entire country. The empirical analysis relies on a novel empirical framework that merges difference-in-difference estimation with duration analysis to exploit a natural policy experiment, namely the introduction and terminationof fees for university studies in several German states. This strategy allows uncovering effects of fees on the intensive margin, while holding constant extensive margin responses such as changes in the composition of the student body or migration responses that occur due to fees.We find that even modest fees have large and significant impacts on study duration and will also examine if the private costs paid by students are recovered through pubilc savings due to students studying faster.

    SOEP Brown Bag Seminar Sensitivity Analysis of Real Income Growth in the SOEP

    A frequently cited result derived from the SOEP suggests that the poorest two quintiles of the population had hardly experienced any real income growth since reunification, and in addition, they did not benefit from the recent positive economic development in Germany. However, the real rise of only 1 per cent turns into growth of nearly 8 per cent over the last 20 years if the start of the investigated period is shifted slightly and if the influence of the newly added migration sample in 2013 is adjusted for. Likewise, the previously observed minus 8.5 per cent real income loss of the poorest ten percent shifts to a real gain of 5.7 percent since 1994. Furthermore, in relative terms the lower income groups have gained as much of the positive economic development of the past decade as the middle and upper income groups. Similar adjustments for the newly added samples of specific family types suggest that these estimates are rather lower bounds of real income growth in recent years.

    Cluster-Seminar Public Finances and Living Conditions The Effect of Parental Leave Policies in Frictional Labor Markets

    I analyze the impact of labor market risks on fertility and female labor supply in a dynamic structural life-cycle model. In particular, I provide insights on whether parental leave policies, such as legal job protection periods, can mitigate these risks. To this end, I estimate a dynamic discrete choice model, using a rich German panel dataset, for the time period between 2007 and 2013. Preliminary findings suggest a strong impact of parental leave job protection on fertility.

    SOEP Brown Bag Seminar Comparing Survey Data and Administrative Records on Gross Earnings: Nonreporting, Misreporting, Survey-Mode, and Earnings Inequality

    The extent of earnings inequality is usually determined using survey data, but these data may not be accurate. Research indicates that some respondents are likely to avoid reporting their gross earnings and others are likely to misreport them. In addition, the format of the survey might affect the accuracy of responses to sensitive questions on issues such as earnings. Given these three possibilities, researchers’ conclusions might be biased. By comparing survey and administrative data, we looked for the nonreporting and misreporting biases suggested by the literature. We also investigated the mode of data collection as a source of nonreporting and misreporting bias. Finally, we analyzed the effects of nonreporting, misreporting, and the mode of data collection on conclusions on the degree of overall earnings inequality. The analyses drew on data from the German employee survey “Legitimation of Inequality Over the Life-Span” and linked administrative data from the Federal Employment Agency (N = 2,282). Using the administrative data as a benchmark, we found that respondents at the lower and upper end of the earnings distribution were more likely to not report or misreport their earnings. Interviewer presence led to higher nonreporting rates as well. Overall inequality was severely underestimated because of nonreporting whereas misreporting had little impact on conclusions on overall inequality.

    Cluster-Seminar Public Finances and Living Conditions Stricter Eligibility Criteria in Disability Insurance: Effects on Diagnoses Protection

    Since the 2001 reform of the disability pension in Germany, occupational invalidity does no longer qualify for a pension. While before the reform the incapability to work in the former job was sufficient for a pension claim, the new regulations require an incapability to work at all. Yet, cohorts born before 1961 have been exempted from the reform to protect their confidence in former legislation. This exogenous variation along birth cohorts allows us to estimate the causal reform effects on pension take-up rates and diagnoses composition using a Regression Discontinuity Design. Working with a 25% sample from the registers of the Statutory Pension Scheme, we show that take-up drops significantly. A disproportionally high share of newly non-eligible individuals suffers from musculoskeletal disorders.

    SOEP Brown Bag Seminar Tax and Transfer Policies and the Female Labor Supply in the EU

    This study measures the effect of tax-benefit policies on female labor supply based on a broad sample of 26 European countries in 2005-2010. The tax-benefit microsimulation model EUROMOD is used to calculate a measure of work incentives at the extensive margin - the participation tax rate, which is then used as the main explanatory variable in a female employment equation. This allows me to deal with the endogeneity of income in a new way by using a simulated instrumental variable based on a fixed EU-wide sample of women. Results suggest that a 10 percentage point increase in the participation tax rate decreases the female employment probability by 2 percentage points. The effect is higher for single mothers, for women in the middle of the skills distribution, and in countries that have lower rates of female employment.

    Cluster-Seminar Public Finances and Living Conditions Labor Market Responses to Tax Reforms

    In a high-tax labor market like France, tax reductions are a popular tool to support employment of low-wage workers. The welfare implications of these exemptions go beyond the directly affected. We ask three questions. First, because employment and wages are determined by both supply and demand of labor, what are the equilibrium effects of tax reductions on different workers? Second, since policy-makers' horizons may be short, are short-run effects very different from long-run outcomes? Finally, thirdly, who should benefit from tax reductions? To answer these questions we estimate an equilibrium search-and-matching model with worker and firm heterogeneity based on French administrative data. While a narrowly focused low-wage tax reduction has distributional advantages, it negatively affects productivity by encouraging job creation from low-productivity firms, making it harder for high-productivity workers to find suitable matches. We simulate short-run effects on employment and welfare and find that they may be contrary to the long-run equilibrium effects.

    SOEP Brown Bag Seminar Does Broadband Internet Affect Fertility?

    The spread of high-speed Internet epitomizes the digital revolution, affecting several aspects of our life. Using high quality German panel data, we test whether the availability of broadband Internet influences fertility choices in a low fertility setting, which is well-known for the difficulty to combine work and family life. Broadband can influence fertility through various pathways, including the provision of information, partnership formation, and, importantly, the opportunity to combine work and family. The latter mechanism, in particular, generates a “digital divide”, with potential benefits for high-skilled workers only. We analyze data from the German Socio-Economic Panel (SOEP), and exploit a strategy devised by Falck et al. (2014) to obtain causal estimates of the impact of broadband on fertility. We find positive effects of high-speed Internet availability on the fertility of high-skilled women over 25s. Effects are not significant among men and low-skilled women. We also find evidence of negative effects on the fertility of under-25 individuals. We show that Internet access significantly increases the share of women reporting teleworking or working parttime. Furthermore, we find positive effects on time spent with children and on overall life satisfaction. Our findings are consistent with the hypothesis that high-speed Internet allows high-educated women to conciliate work and motherhood and may promote fertility with a "digital divide". At the same time, higher access to information on the risks and costs of early pregnancy and childbearing may explain the negative effects on younger adults.

    Cluster-Seminar Public Finances and Living Conditions The effect of parental education on the offspring's mental health

    We are the first to estimate the causal effect of parental education on a wide range of the adult offspring's mental health outcomes. Theoretical considerations predict positive direct and indirect effects of parental education on the offspring's mental health. But the relation between parental education and mental health outcomes is plagued by endogeneity. To circumvent this problem, we exploit exogenous variation in schooling which is completely unrelated to the offspring's mental health. In contrast to our theoretical considerations, we find no positive effects of parental education on the offspring's mental health. Moreover, preliminary results point at a negative effect of parental education and the offspring's mental health.

    SOEP Brown Bag Seminar Dynamic binary panel data models in presence of autocorrelation in the error term. A Monte-Carlo study

    Dynamic panel data models are often applied to estimate the degree of state dependence. For instance, it has often been shown that there is state dependence in unemployment, i. e. unemployment in present causally increases the probability of unemployment in future. This paper uses Monte-
    Carlo simulations to compare several dynamic linear and nonlinear panel data models for binary dependent variables. In particular, we focus on data generating processes where dynamics may stem from true state dependence or from autocorrelation in the error term (which may lead to the measurement of spurious state dependence). We employ estimators which explicitly model both sources of persistence and compare their performance with standard dynamic models. Furthermore, we test how these estimators perform in presence time-varying unobserved variables which follow time trends or which may be described by a moving-average model.

    SOEP Brown Bag Seminar Special Brown Bag Seminar: Are Top Shares a Good Measure of Inequality?

    Newly precise evidence of the trajectory of top incomes in the United States and around the world relies on top shares and top-to-bottom ratios, prompting new inquiry into their properties as inequality measures. Current evidence suggests a mathematical link between top shares and the Gini coefficient and empirical links extending as well to the Atkinson measure. The work reported in this paper strengthens that evidence, making several contributions: First, it formalizes the shares and ratios, showing that as monotonic transformations of each other, they are different manifestations of a single underlying inequality measure. Second, it presents a standard form of the underlying inequality measure that satisfies the principle of normalization – ranging from zero to one, with zero representing perfect equality and inequality increasing as the measure goes toward one -- but also finds that, compared to shares and ratios, the standard form is somewhat blunt in depicting changes in inequality. Third, it investigates the measure in mathematically specified probability distributions, showing that it is monotonically related to classical measures, such as the Gini, Atkinson, and Theil measures and the coefficient of variation. Thus, the evidence to date suggests that the family of top shares and top-to-bottom ratios is a genuine inequality measure and a useful all-purpose proxy for other inequality measures. Moreover, this new measure is further distinguished by its ease of calculation and ease of interpretation, making it a widely appealing measure of inequality. This work also provides new insights, for example, that, given nonlinearities in the (monotonic) relations among inequality measures, Spearman correlations are more appropriate than Pearson correlations, and that weakening of correlations – such as between the Gini and Atkinson measures or between the Gini and top shares -- signals differences and shifts in distributional form, themselves signals of income dynamics.

    SOEP Brown Bag Seminar Interpersonal Perceptions and Interviewer Effects in Face-to-Face Surveys

    It is well known that the presence of an interviewer can affect responses and thereby introduce variance and bias into survey estimates. For instance, some respondents tend to adjust their true answers towards social norms or specific characteristics of the interviewer in order to appear in a good light. When investigating these interviewer effects, survey research mainly focused on interviewer socio-demographics and only a few studies have examined effects of not directly observable characteristics such as interviewer personality, attitudes and beliefs. Moreover, survey research lacks of insights on how interviewers’ and respondents’ interpersonal perceptions of each other affect respondent answers to related questions. For this project, self-reports of 1,184 respondents and 114 interviewers as well as their mutual perceptions of each other were collected in the context of the Socio-Economic Panel Study Innovation Sample (SOEP-IS) in 2015/2016. Data collection covered attitudes and opinions towards a variety of political and social issues. This presentation includes results on the impact of interviewer opinions on respondent answers, the nature and accuracy of interpersonal inferences, as well as their impact on respondent self-reports.
