This report provides an overview on the economics of attention intermediaries. It addresses the following questions: What are the economics of attention intermediaries? For competition policy, how should markets be defined and market power of attention intermediaries be assessed? What theories...

We present a banking model with imperfect competition in which borrowers’ access to credit is improved when banks are able to transfer credit risks. However, the market for credit risk transfer (CRT) works smoothly only if the quality of loans is public information. If the quality of loans is...

In the current recession, politicians grant state aid of yet unknown dimensions. But what is the most efficient measure for granting such aid? We use a theoretical model with firms that differ in their creditworthiness and compare different types of direct subsidies with indirectly subsidized...

We develop a model of rational bubbles based on the assumptions of unknown market liquidity and limited liability of traders. In a bubble, the price of an asset rises dynamically above its steady-state value, justified by rational expectations about future price developments. The larger the...

This paper empirically investigates the effect of government bail-out policies on banks outside the safety net. We construct a measure of bail-out perceptions by using rating information. From there, we construct the market shares of insured competitor banks for any given bank, and analyze the...

The explicit or implicit protection of banks through government bail-out policies is a universal phenomenon. We analyze the competitive effects of such policies in two models with different degrees of transparency in the banking sector. Our main result is that the bail-out policy unambiguously...

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...

The severity and depth of the recent financial crisis hit many by surprise. Despite warning signs, the financial system seems to have been unable to aggregate existing information. As the events of Fall 2008 showed, many investors were caught off guard by the large number of banks collapsing...
