Futures Hedging Under Price, Basis, and Production Risk
研究企业在面临价格、基差和产量三重风险时的最优期货套期保值问题，推导出精确解并应用于爱荷华州大豆生产，发现最优套保依赖于风险态度。
Abstract We consider the hedging problem of a firm that has three sources of risk: price, basis, and yield uncertainty. An exact solution for the optimal futures hedge is derived under the assumption that the three random variables are jointly normally distributed and that utility is of the CARA type. Unlike the mean‐variance approximation applied in previous research, we show that the optimal hedge does depend on risk attitudes, even when the agent perceives the futures price as being unbiased. The theoretical results are applied empirically to the problem of hedging soybean production in Iowa. The exact solution, relying on CARA and normality, is compared with numerical solutions under lognormal distributions and CRRA utility.
