Optimal Hedging Strategies and Interactions between Firms

This paper studies corporate risk management in a context of financial constraints and imperfect competition in the product market. The paper shows that interactions between firms affect their hedging strategies. As a general rule, firms' hedging demands decrease with the correlation between their internal funds and investment opportunities. Moreover, when a firm's hedging demand is high in the case where investments are strategic substitutes, its hedging demand is low in the case where investments are strategic complements and vice versa.
