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...

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...

We analyze potential gains from hypothetical mergers in local public transport using the non-parametric Data Envelopment Analysis with bias corrections by means of bootstrapping. Our sample consists of 41 public transport companies from Germany's most densely populated region, North...

In this paper, we present a nonparametric comparative efficiency analysis of 179 communal public transport bus companies in Germany (1990-2004). We apply both deterministic data envelopment analysis (DEA) and bootstrapping to test the robustness of our estimates and to test the hypothesis of...

We analyse preferences for public, private or mixed provision of childcare theoretically and empirically. We model childcare as a publicly provided private good. Richer households should prefer private provision to either pure public or mixed provision. If public provision redistributes from...

In a carbon constrained world, at least four classes of greenhouse gas mitigation options are available: Energy efficiency, fuel switching, introduction of carbon dioxide capture and storage along with renewable generating technologies, and reductions in emissions of non-CO2 greenhouse gases....

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...

Our paper deals with modeling the effects of introducing a market-based tool for improving end-users' efficiency in an energy market which is already regulated through a cap-and-trade system for green house gas emissions and a quota system meant to improve competitiveness of energy produced...

We estimate the elasticity of enrollment into higher education with respect to the amount of means tested student aid (BAfoeG) provided by the federal government using the German Socioeconomic Panel (SOEP). Potential student aid is derived on the basis of a detailed taxbenefit microsimulation...

Risk attitudes have an impact on not only the decision to become an entrepreneur but also the survival and failure rates of entrepreneurs. Whereas recent research underpins the theoretical proposition of a positive correlation between risk attitudes and the decision to become an entrepreneur,...
