Optimal Financial Fragility

Pablo Kurlat  

Optimal incentive schemes for managers may involve liquidating a firm following bad news. Fragile financial structures, vulnerable to runs, have been proposed as a way to implement these schemes despite their ex-post inefficiency. I show that in general these arrangements result in multiple equilibria and, even allowing arbitrary equilibrium selection, they do not necessarily replicate optimal allocations. However, if output follows a continuous distribution and creditors receive sufficiently precise individual early signals, then there exists a fragile financial structure such that global games techniques select a unique equilibrium which reproduces the optimal allocation.
