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.

    Cluster-Seminar Public Finances and Living Conditions Retirement and social connection in old age

    Facing an aging population, many societies discuss policies to prolong work lives. At the individual level, such policies could affect social connectedness in several ways. On the one hand, prolonged work lives could promote a healthier social life at advanced ages by maintaining job-related networks for longer. On the other hand, retirement might boost quantity and quality of social networks by an increase in leisure time. This paper sheds light on the net effects of retirement on social wellbeing and the elderly’s social networks with a particular focus on heterogeneity patterns. Using data from SHARE, we analyze whether country, gender, or education are important dimensions of heterogeneity. Potential endogeneity of the individual retirement status is accounted for using an instrumental variables approach. We thereby exploit variation in the individual retirement decision that is induced by pensionable age thresholds. The results suggest that retirement is not an important determinant for social connectedness. Moreover, effect heterogeneity is not particularly pronounced in the dimensions under study.

    SOEP Brown Bag Seminar Turning Points in Life Courses: Conceptualization, Measurement and Typology

    Life course research allows studying issues such as social inequality, social status attainment, education, migration, family formation, or gender as processes that involve continuity and change. Turning points are a key concept in this research field because they can help understand processes of overhaul and stability in life courses. In general terms, turnings points describe phases in which a person’s life changes directions fundamentally. Despite their prominent role in life course research, concrete conceptualizations of turning points in the literature vary and are often fuzzy. We suggest developing an analytic definition of turning points that captures core characteristics and helps analyzing turning points with either quantitative or qualitative analysis. To do so, we use a mixed methods data set comprised of SOEP data and qualitative in-depth interviews with SOEP participants. We employ qualitative case analysis to construct a thick concept of turning points in status attainment trajectories and use cluster analysis of SOEP data to explore whether our concept of turning points reflects meaningful groupings in the SOEP data. In Wednesday's Brown Bag Seminar, we will give an overview of our work in progress and (hopefully) present first results from the cluster analysis.

    Cluster-Seminar Public Finances and Living Conditions The Increasing Longevity Gap and the Pension System

    We use social security records to document the heterogeneity in life expectancy by lifetime earnings for West Germany and we analyze how this longevity gap has evolved over cohorts. In line with previous studies, we provide evidence that the earnings-related longevity gap is increasing over cohorts. We then propose a decomposition to disentangle the role of the increasing earnings inequality over cohorts and the effect of changes in the earnings gradient on life expectancy. Finally, we study the distributional implications of the increasing longevity gap for the pension system. First, we show how the heterogeneity in life expectancy affects the distribution and the inequality of social security wealth and we document how this has evolved between the cohorts. Second, we calculate contribution/benefit ratios and compare the rates by lifetime earnings and between cohorts. Third, we extend the analysis by also accounting for survivor pensions and heterogeneous life expectancies of surviving spouses.

    Cluster-Seminar Public Finances and Living Conditions Low-income children, pre-school peer groups, and early child development: evidence from England

    Early education has increasingly been prioritised within OECD countries’ policy agenda, with a growing focus on early education’s potential to narrow the social class gaps in child development. The positive impact of early provision depends upon a number of factors, however – including the influence of the peers with whom a child interacts. Emerging evidence suggests that peers can directly influence children’s pre-academic skills, as well as affect the quality of the interactions between adults and children at group level.
    This paper examines socio-economic segregation in early education in England. Drawing on administrative data, we analyse a cohort of three-and-four-year-olds who attended early education in 2011 (approximately 560,000 children). We investigate the distributions of children across settings according to income-level and find little evidence of segregation. We also examine the relationships between peer groups in early education and children’s development in the initial year of formal schooling. We find that children who are themselves low income and attend settings with fewer peers who are also low-income have better developmental assessments.  However, this variation is largely eliminated once additional child-level characteristics, the characteristics of settings and of local areas are accounted for.

    Cluster-Seminar Public Finances and Living Conditions The Effect of Pension Reforms on Savings Behavior

    Many OECD countries are currently undergoing reforms of their statutory pension schemes. In theory, a decrease of pension generosity can have a positive or negative effect on private savings - depending on the corresponding level of employment effects. Thus, it is an empirical question to determine the sign of the effect. A particular reform of the German Statutory Pension Scheme lifted the early retirement age (ERA) of women. The reform was implemented along birth cohorts, allowing for an intuitive identification strategy and causal interpretation of effects.
    While previous studies found positive effects of other generosity decreasing pension reforms on private savings, this is the first study isolating the effect of an increase of the ERA on savings. An upward-shift of the ERA by 3 to 5 years has a statistically and economically significant negative effect on private monthly savings of single women. The effects in the subsample of couples are insignificant.
