I develop a theoretical model to examine the effect of capital requirements on risk taking and market structure of banks. Within a portfolio choice model, I allow for heterogeneous productivity among banks and consider the simultaneous capital regulation with a leverage ratio and a risk-weighted...

This paper analyses the impact of transparency regulations on Super 95 and Diesel prices in Austria, France, and Germany to shed new light on the price effects of regulatory policies. To identify the effects of regulation, we use publicly available data from January 2005 to the end of December...

Minimum capital requirement regulation forces banks to refund a substantial amount of their investments with equity. This creates a buffer against losses, but also increases the cost of funding. If higher refunding costs translate into higher loan interest rates, then borrowers are likely to...

Minimum capital requirement regulation forces banks to refund a substantial amount of their investments with equity. This creates a buffer against losses, but also in- creases the cost of funding. If higher refunding costs translate into higher loan interest rates, then borrowers are likely to...

This paper studies banks' competitive behavior on the deposit side of the Italian retail banking industry. We use a structural model to estimate demand for deposit services and test several supply models. We find that both the competitive, differentiated product Bertrand and the perfectly...

We analyze the relationship between bank size and risk-taking under the New Basel Capital Accord. Using a model with imperfect competition and moral hazard, we show that the introduction of an internal ratings based (IRB) approach improves upon flat capital requirements if the approach is...

Bank regulators interfere with the efficient allocation of resources for the sake of financial stability. Based on this trade-off, I compare how different capital requirements affect default probabilities and the allocation of market shares across heterogeneous banks. In the model, banks‘...

During the last two decades, bundling has become a hot topic for Industrial Organization economists, mainly as a result of legal actions against Microsoft (Crampes and Hollander 2007). In this spirit, the literature has thus far focused on asymmetric settings where one firm holds a monopoly for...
