How can public pension systems be reformed to ensure fiscal stability in the face of increasing life expectancy? To address this pressing open question in public finance, we estimate a life-cycle model in which the optimal employment, retirement and consumption decisions of forward-looking...

This paper contributes to the policy-relevant question whether self-employment is a way out of (long-term) unemployment. We estimate the relationship between the entry rate into self-employment and previous (long-term) unemployment on the basis of pseudo-panel data for Germany in the period...

Entrepreneurial activity is often regarded as an engine for economic growth and job creation. Through tax policy, governments possess a potential lever to influence the decisions of economic agents to start and close small businesses. In Germany, the top marginal income tax rates were reduced...

We analyze potential effects of demographic change and political constellations on higher education spending. In our panel analysis of west German states (Laender) for the period 1985 to 2002 we find empirical evidence for the hypothesis of a negative relationship between demographic aging and...

We assess the labor supply effects of two quot;making work payquot; reforms in Germany. We provide evidence in favor of policies that distinguish between low effort and low productivity by targeting individuals with low wages rather than individuals with low earnings. In assessing the policies...

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...

We develop a structural multi-factor labour demand model which distinguishes between eight labour categories including non-standard types of employment such as marginal employment. The model is estimated for both the number of workers and total working hours using a new panel data set. For...

Typically, laboratory experiments suffer from homogeneous subject pools and self-selectionbiases. The usefulness of survey data is limited by measurement error and by thequestionability of their behavioral relevance. Here we present a method integrating interactiveexperiments and representative...

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...
