Ex Ante Versus Ex Post Regulation of Bank Capital
AbstractThe current debate on the new Basel Accord gives rise to a natural question about the appropriate form of capital regulation.We construct a simple framework to analyze this issue. In our model the risk carried by a bank as well as managerial risk preference are a bank's private information. We show that ex ante constraints waste the superior risk information of a bank, while an ex post regime makes full use of it. However, the latter is more vulnerable to the problem of unknown managerial risk-aversion. The results imply that the two regimes are complements, rather than substitutes. Further, under plausible conditions, an ex post regime emerges as the dominant element of the optimal combination. We use the results to shed light on current policy concerns. In particular, our results provides theoretical underpinning for the inclusion of pillar 2 alongside pillar 1 in Basel II.
