When possible income tax reforms are debated, the suspected impact on entrepreneurship is often used as an argument in favour or against a certain policy. Quantitative ex-ante evaluations of the effect of certain tax reform options on entrepreneurship based on microeconometric research have not...

The positive association between moderate alcohol consumption and wages is well documented in the economic literature. Positive health effects as well as networking mechanisms serve as explanations for the "alcohol-income puzzle." Using individual-based microdata from the GSOEP for 2006, we...

In this paper we present an international cross-country benchmarking analysis for utility regulation of France and Germany, the two largest electricity distribution countries in Europe. We examine the relative performance of 99 French and 77 German distribution companies operating within two...

Based on a theoretical framework on informal, custodial and non-custodial sentencing, the paper provides econometric tests on the effectiveness of police, public prosecution and courts. Using a unique dataset covering German states for the period 1977- 2001, a comprehensive system of criminal...

In this paper we develop a discrete model of optimal taxation of married couples and empirically discuss the optimality of income taxation for this group. To this end, we derive the social welfare function which guarantees that joint taxation of married couples is optimal. We will contrast this...

In this paper I assert that the entrepreneurial spirit can also exist in salaried jobs. I study the determinants of wages and the labor market success of two kinds of entrepreneurial women in Germany - self-employed and salaried businesswomen - and investigate whether ethnicity is important in...

Support schemes for unemployed persons aiming to become self-employed have been recently reformed several times. In 2003, the "start-up-subsidy" (Existenzgründungszuschuss) was added to the existing "bridging-allowance" (Überbrückungsgeld) and the two programs to-gether led to a strong...

We estimate a dynamic structural life-cycle model of employment, non-employment and retirement that includes endogenous accumulation of human capital and intertemporal non- separabilities in preferences. Additionally, the model accounts for the effect of the tax and transfer system on work...

Using a firm-level panel data set I assess whether dynamic models of in- vestment provide an empirically fruitful framework for analyzing tax effects on changes in capital stock. In particular I estimate a one-step error correction model (ECM) complementing the usual estimation of a distributed...

We analyse the convergence and heterogeneity of living standards between East and West Germany since unification. Based on data from the German Socio-Economic Panel (GSOEP), we compare total individual income of permanent adult residents, including retirees and the unemployed, of East and West...
