We show that the efficient allocation of production capacity can turn a competitive industry and downstream market into an imperfectly competitive one. Even though downstream firms have symmetric production technologies, the downstream industry structure will be symmetric only if capacity is...

In repeated normal-form (simultaneous-move) games, simple penal codes (Abreu, 1986, 1988) permit an elegant characterization of the set of subgame-perfect outcomes. We show that the logic of simple penal codes fails in repeated extensive-form games. By means of examples, we identify two types of...

This paper examines common regulation as cause of interbank contagion. Studies based on the correlation of bank assets and the extent of interbank lending may underestimate the likelihood of contagion because they do not incorporate the fact that banks have a common regulator. In our model, the...

We analyze financial support for the entrepreneurial sector. State support can raise welfare by relaxing financial constraints, but it can also reduce lending standards if entrepreneurs substitute public sources of collateral for their own assets, if it encourages excessive entrepreneurial...

Recent academic work and policy analysis give insight into the governance problems exposed by the financial crisis and suggest possible solutions. We begin this paper by explaining why governance of banks differs from governance of nonfinancial firms. We then look at four areas of governance:...
