Hedging to market-wide shocks and competitive selection

This paper examines hedging against a large market-wide shock in a model with heterogeneous firms and sunk costs of entry. If hedging is voluntary only the most efficient firms hedge against this shock, a finding in line with empirical evidence but at odds with standard motivations for risk management. Hedging affects the critical level of the marginal cost needed to operate in the market. A setting with mandatory hedging is associated with stronger competition than when hedging is voluntary which, in turn, is associated with stronger competition than when hedging is unavailable.
