If there were no impediments to the flow of capital across space, then interest rates would equalized. We provide evidence to the contrary. We find significant differences in interest rates across the South Indian state of Tamil Nadu, i.e. evidence that financial markets are fragmented. We also...

This paper studies how credit constraints develop over bank relationships. I analyze a unique dataset of matched loan application and loan contract information and measure credit constraints as the ratio of requested to granted loan amounts. I find that the most important determinants of...

Basu (2006) argues that the prevalence of 99 cent prices in shops can be explained with rational consumers who disregard the rightmost digits of the price. This bounded rational behaviour leads to a Bertrand equilibrium with positive markups. We use data from an Austrian price comparison site...

This paper employs a two-period life-cycle model to derive the optimal tax policy when educational investments are subject to endogenous credit constraints. Credit constraints arise from the limited commitment of creditors to repay loans and from the moral hazard problem due to private...

Credit constraints are more frequent among growth companies with large investment opportunities. For the same reason, profit taxes may harm innovative firms more than standard ones. This paper develops a model of heterogeneous firms where an endogenous share opts for innovation and faces credit...

Consumers buy products even if they find it too time-consuming to evaluate products carefully. I present a simple market model with sequential consumer search and differentiated products in which consumers may purchase products without evaluation. In a market with evaluation cost heterogeneity...

We study research joint ventures (RJV) given that knowledge spillovers depend positively on the technological proximity between rms. Possible scenarios differ in the intensity of collaboration, i.e., the (non)coordination of research activities and the extent of knowledge sharing. The...

Inspired by recent regulations in the New York ICAP market, this paper examines the effect of price regulations on a multi-unit uniform price auction. General bid caps reduce the maximum price below the bid cap, but also the minimum potential market price below the cap. A bid cap only for the...

This paper investigates the relationship between innovation activities and market structure in German chemical industry. We present a formal model that suggests the existence of a self-enforcing dynamic feedback between market concentration and innovation. This model is tested on the basis of...
