From standard portfolio-choice theory it is well-understood that background risk, overwhelmingly due to wage risk, is one of the central determinants of individuals’ portfolio composition: higher background risk reduces risky investments. However, if background risk is negatively correlated with financial market risk, higher background risk implies more risky investment. We quantify the influence of ...

Do the processes underlying destination-language acquisition differ between recently arrived refugees and other new immigrants? Based on a well-established model of language learning according to which language fluency is a function of efficiency, incentives, and exposure, this study addresses general processes of language learning as well as conditions specific to refugees. Longitudinal data on refugees ...

Does the politico–economic system affect preferences for immigration? In this study, I show that individuals exposed to life under state socialism have formed and persistently hold different attitudes toward immigration. By exploiting the division and reunification of Germany, I estimate the influence of state socialism on attitudes toward immigration. Drawing on rich individual panel data, I find ...

Critical theories of education but also the dynamics of skill formation model predict that the education system reproduces educational inequalities. Contrary to this hypothesis, empirical studies comparing the change in inequalities in academic performance over the summer to the change in these inequalities during the school year, have argued that schooling reduces inequalities in educational performance. ...

Global migration towards and within Europe remains high, shaping the structure of populations. Approximately 24% of the total German population had a migration background in 2017. The aim of the study was to analyze the association between migration background and health-related quality of life (HrQoL) in Germany. The analyses were based on 2014 and 2016 data of the German Socio-Economic Panel. Differences ...

This paper examines whether biased income expectations due to overconfidence lead to higher levels of debt-taking. In a lab experiment, participants can purchase goods by borrowing against their future income. We exogenously manipulate income expectations by letting income depend on relative performance in hard and easy quiz tasks. We successfully generate biased income expectations and show that participants ...

Evidence shows that working time mismatch, i.e. the difference between actual and desired working hours, is negatively related to employees' job satisfaction. Using longitudinal data from the German Socio-Economic Panel, we examine the potential moderating effect of working time autonomy on this relation and we also consider the corresponding role of gender. First, individual fixed effects panel ...

In this paper, we study how the tax-and-transfer system reduces the inequality of lifetime income by redistributing lifetime earnings between individuals with different skill endowments and by providing individuals with insurance against lifetime earnings risk. Based on a dynamic life-cycle model, we find that redistribution through the tax-and-transfer system offsets around half of the inequality ...

This paper presents non-take-up rates of benefits from the German Income Support for Job Seekers scheme, called Unemployment Benefit II (Arbeitslosengeld II ). Eligibility to these benefits is simulated by applying a microsimulation model based on data from the Socio-economic Panel for the years 2005 to 2014. To ensure the quality of the results, feasible upper and lower bounds of nontake-up are shown ...

After arriving in a new country, refugees are typically dependent on professional support to re-establish their livelihood. However, it is well documented that refugees face barriers when seeking access to services aimed at facilitating their settlement. This study examines refugees’ support service needs, their actual utilization, and investigates the impact of social and human capital on service ...
