We consider a multimarket framework where a set of firms compete on two interrelated oligopolistic markets. Prior to competing in these markets, firms can spy on others in order to increase the quality of their product. We characterize the equilibrium espionage networks and networks that...

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...

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...

The gender wage gap is a persistent labor market phenomenon. Most research focuses on the determinants of these wage differences. We contribute to this literature by exploring a different research question: if wages of women are systematically lower than male wages, what are the distributional...

Why do people work unpaid overtime? We show that remarkable long-term labor earnings gains are associated with unpaid overtime in West Germany. A descriptive analysis suggests that over a 10-year period workers with unpaid overtime experience on average at least a 10 percentage points higher...

In this paper employment effects of a sectoral minimum wage in the German construction sector are estimated from a single cross-sectional wage distribution using parametric and semi-parametric models. Parametric functional form assumptions seem too restrictive and lead to implausible results. We...

In this paper I investigate the causal returns to education for different educational groups in Germany by employing a new method by Klein and Vella (2010) that bases identification on the presence of conditional heteroskedasticity. Compared to IV methods, key advantages of this approach are...

The paper investigates the role of social norms as a determinant of individual attitudes by analyzing risk proclivity reported by immigrants and natives in a unique representative German survey. We employ factor analysis to construct measures of immigrants' ethnic persistence and assimilation....
