A diversified portfolio of risk arbitrage positions produces an abnormal return of 0.6-0.9% per month over the period from 1981 to 1996. We trace these profits to practical limits on risk arbitrage. In our model of risk arbitrage, arbitrageurs' risk-bearing capacity... View Details

Input Constraints and the Efficiency of Entry: Lessons from Cardiac Surgery
By: David M. Cutler, Robert S. Huckman and Jonathan T. Kolstad
Prior studies suggest that, with elastically supplied inputs, free entry may lead to an inefficiently high number of firms in equilibrium. Under input scarcity, however, the welfare loss from free entry is reduced. Further, free entry may increase use of high-quality... View Details
