We argue that input and output hedging are very different. Furthermore, if firms are able to influence output prices, output hedging can create incentives for profit reducing over-production, which are not present in competitive markets. Thus we expect firms to hedge outputs less often than inputs and firms with market power should hedge outputs less often than competitive firms. We test these predictions on a sample of S&P500 firms from 2001 to 2005. The findings are consistent with our conjectures. Firms with output market power are less likely to hedge commodity risk. A placebo test shows that the same empirical regularities do not apply to currency hedging where there are competitive international markets. Finally, our empirical framework, which differentiates between input and output hedging, can also help reconcile conflicting results in prior studies.
