We study the effects of improvements in eBay's rating mechanism on seller exit and continuing sellers' behavior. Following a large sample of sellers over time, we exploit the fact that the rating mechanism was changed to reduce strategic bias in buyer rating. That improvement did not lead to...

We study a differentiated product market in which an investor initially owns a controlling stake in one of two competing firms and may acquire a non-controlling or a controlling stake in a competitor, either directly using her own assets, or indirectly via the controlled firm. While industry...

In the period following WW II. until the country accessed the European Union, cartels were legalized in Austria, upon registration with the Austrian Cartel Court. We obtained access to the registration data, and scanned them all towards a microeconomic analysis of contracting behavior between...

We investigate the interplay between firms' R&D decisions and labor market competition, and how this influences equilibrium location choices and welfare. Firms engage in risky R&D activities and thus create stochastic product and implied labor demand. Spatial agglomeration is more likely in...

We explore the determinants and effects of trust relationships between upstream suppliers and downstream producers. Using unique survey data on individual supplier-buyer relationships in the German automotive industry, we show, by means of different measures of supplier-buyer trust, that higher...

In this paper we discuss determinants of firm survival and growth in Germany within its pre-1989 boundaries. We develop our central hypotheses on the basis of a simple theoretical model describing the self-selection of heterogeneous entrepreneurs into particular legal forms, and the implications...

In this paper, we present a micro estimate determining taxable income as a function of gross income and all major deduction options depending on household and asset categories. It is shown that tax savings strongly increase with increasing income, resulting in a decreasing effective marginal tax...

In this paper, we report results of an ongoing empirical analysis of firm dynamics in East Germany. After discussing specifics of a newly available data set with information on more than 100.000 firms, we analyze patterns of business starts and failures. Furthermore, we present preliminary...

We analyze the effects of downstream firms' acquisition of pure cash flow rights in an efficient upstream supplier when all firms compete in prices. With an acquisition, downstream firms internalize the effects of their actions on their rivals' sales. Double marginalization is enhanced. Whereas...
