Abstract：We study the risk management strategies of two manufacturers who procure a commodity from a supplier as the main input to produce a homogeneous product and compete in a downstream market. Themanufacturers can adopt financial hedging and/or spot trading to control risks. Financial hedging can reduce profit variance by trading a financial asset, whereas spot trading as an operational hedging instrument canreduce the demand-supply mismatch risk. Our analysis indicates that neither financial hedging nor spot trading can completely dominate the other when manufacturers adopt a single risk management strategy.Spot trading fits well in scenarios with low spot price volatilities, low demand uncertainties, and small niche markets, whereas financial hedging is suitable for the opposite situations. Further, we find that thecombination of financial hedging and spot trading completely dominates spot trading; however, it cannot completely dominate financial hedging. An important implication is that financial hedging can substitute spot trading, or complement spot trading to generate additional value to manufacturers; however, spot trading cannot substitute financial hedging. Another interesting result is that asymmetric risk management equilibrium arises irrespective of whether only a single risk management strategy is accessible or both risk management strategies are available becausesymmetric manufacturers must adopt differentiated risk management strategies to fully utilize their benefits to alter the nature ofcompetition.
