Religious Heterogeneity and Fiscal Policy: Evidence from German Reunification

Theoretical work based on social identity theory predicts that population diversity undermines redistributive public policies. This article tests this proposition exploiting an exogenous shock in diversity due to Germany’s reunification. In contrast to previous work on ethno-linguistic or racial heterogeneity, we specifically analyze religious diversity, which is an increasingly relevant social cleavage ...

Entrepreneurship versus Joblessness: Explaining the Rise in Self-Employment

A large share of the workforce throughout the developing world is self-employed, and this proportion has increased in recent decades. Assessments of this development vary, with pull factors such as high returns to capital contrasted with push factors such as barriers to more desirable salaried jobs. Using a long panel dataset from Ghana, we empirically investigate the changing structure of earnings ...

Wealth Effects on Job Preferences

Preferences over jobs depend on wages and non-wage aspects. Variation in wealth may change the importance of income as a motivation for working. Higher wealth levels may make good non-wage characteristics relatively more important. This hypothesis is tested empirically using a reduced form search model in which differential job leaving rates identify willingness to pay for non-wage aspects of jobs. ...

Only Conservatives Are Voting in the Rain: Evidence from German Local and State Elections

In this note, we use data from different elections in the German state of North-Rhine Westphalia between 1975 and 2010 to show that the Conservatives profit from lower voter turnout at the expense of the Social Democrats. We deal with the endogeneity of voter turnout by using election day rain as an instrumental variable. Our particular contribution is the comparison of municipal and state electio ...

Long-term Care Insurance and Carers' Labor Supply: A Structural Model

In Germany, individuals in need of long-term care receive support through benefits of the long-term care insurance. A central goal of the insurance is to support informal care provided by family members. Care recipients can choose between benefits in kind (formal home care services) and benefits in cash. From a budgetary perspective, family care is often considered a cost-saving alternative to formal ...

Bayesian Procedures as a Numerical Tool for the Estimation of an Intertemporal Discrete Choice Model

Discrete choice models usually require a general specification of unobserved heterogeneity. In this paper, we apply Bayesian procedures as a numerical tool for the estimation of a female labor supply model based on a sample size that is typical for common household panels. We provide two important results for the practitioner: First, for a specification with a multivariate normal distribution for the ...

Signature Requirements and Citizen Initiatives: Quasi-experimental Evidence from Germany

Signature requirements are often used as hurdles to prevent overuse of direct democratic instruments such as citizen initiatives. We evaluate the causal effect of lowering signature requirements on the number of observed citizen initiative petitions. Based on municipal-level data for Germany, we make use of changes in signature requirements that occur at specific population thresholds to build an identification ...

Empirical Welfare Analysis with Preference Heterogeneity

We apply recently proposed individual welfare measures in the context of preference heterogeneity, derived from structural labour supply models. Contrary to the standard practice of using reference preferences and wages, these measures preserve preference heterogeneity in the normative step of the analysis. They also make the ethical priors, implicit in any interpersonal comparison, more explicit. ...

The Mayor's Advantage: Causal Evidence on Incumbency Effects in German Mayoral Elections

Lifetime Earnings Inequality in Germany

We employ German social security records to investigate intragenerational lifetime earnings inequality and mobility of yearly earnings for 35 cohorts, starting with the birth year 1935. Our main result is a striking secular rise of intragenerational inequality in lifetime earnings: West German men born in the early 1960s are likely to experience about 85% more lifetime inequality than their fathers. ...
