This article studies the design of optimal mechanisms to regulate entry in natural oligopoly markets, assuming the regulator is unable to control the behavior of firms once they are in the market. We adapt the Clarke-Groves mechanism, characterize the optimal mechanism that maximizes the...

I propose a model in which firms can convey their quality by listing on a stock exchange. To list, firms must comply with costly listing requirements allowing investors to recognize imperfectly their quality. A profit maximizing exchange may set listing requirements leading to high information...

In the Basel regulation the required capital of a financial institution is based on conditional measures of the risk of its future equity value such as Value-at-Risk, or Expected Shortfall. In Basel 2 the uncertainty on this equity value is captured by means of changes in asset prices (market...
