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...

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...

The literature argues that research spin-offs (RSOs)-enterprises originating from a university or research institute-appear to have higher innovative potential and capabilities than other start-ups, at least in the early stages of their development. Yet, little is known about the innovative...

We decompose permanent earnings risk into contributions from hours and wage shocks. To distinguish between hours shocks, modeled as innovations to the marginal disutility of work, and labor supply reactions to wage shocks we formulate a life-cycle model of consumption and labor supply. Both...

We empirically analyze the heterogeneous welfare effects of unemployment insurance and social assistance. We estimate a structural life-cycle model of singles' and married couples' labor supply and savings decisions. The model includes heterogeneity by age, education, wealth, sex and household...

In this study we investigate the impact of the thin capitalization rule (TCR), introduced in Germany in 2008, on firms' capital structure, investment and profitability. The identification of the causal effects is based on the escape clauses in the regulation using a difference-in-difference...

Tax competition for the mobile factor capital has led to a trend in many countries to levy lower taxes on interest income, often introducing differential taxation between interest and business income. In this study, we analyze the effect of such differential taxation on the debt ratio of firms....

This paper investigates the link between the optimal level of non-financial firms' leverage and macroeconomic uncertainty. We develop a structural model of a firm's value maximization problem that predicts that as macroeconomic uncertainty increases the firm will decrease its optimal level of...

We analyze the role of public support in the financing pattern of R&D in German SMEs and their assessment of financing conditions in the context of other framework conditions for innovation. In Germany, there is a diversity of overall well-funded technology-neutral and technology-specific...
