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 analyze whether start-up rates in different industries systematically change with business cycle variables. Using a unique data set at the industry level, we mostly find correlations that are consistent with counter-cyclical influences of the business cycle on entries in both innovative and...

Case and Deaton (2015) document that, since 1998, midlife mortality rates are increasing for white non-Hispanics in the US. This trend is driven by deaths from drug overdoses, suicides, and alcohol-related diseases, termed as deaths of despair, and by the subgroup of low-educated individuals. In...

Germany experienced a unique rise in the level of self-employment in the first two decades following unification. Applying the non-linear Blinder-Oaxaca decomposition technique, we find that the main factors driving these changes in the overall level of self-employment are demographic...

We analyze the link between R&D, innovation, and productivity in MSMEs with a special focus on micro firms with fewer than 10 employees; usually constituting the majority of firms in industrialized economies. Using the German KfW SME panel, we examine to what extent micro firms are different...

We evaluate three policy reforms targeted at older unemployed people: (i) an hourly wage subsidy, (ii) an in-work credit, and (iii) a subsidy of social security contributions on low wages. The work incentive, labour supply and welfare effects of these hypothetical reforms are analysed on the...

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...

This paper investigates whether self-employed households use consumer loans – in particular instalment loans and overdrafts – to finance business activities. Controlling for financial and non-financial household variables we show that self-employed households particularly use personal...

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 systematically investigates whether different kinds of personality characteristics influence entrepreneurial development. On the basis of a large, representative household panel survey, we examine the extent to which the Big Five traits and further personality characteristics, which...
