演讲内容简介:

This paper considers a supply chain comprising one risk-neutral manufacturer (he) and one risk-averse retailer (she). The manufacturer procures consumption commodities as major input for production and sells the final products to the retailer. The retailer then sells the final products to the market at a stochastic clearance price.  We investigate a form of flexible supply contract that allows the manufacturer to determine the product wholesale price, and the retailer to determine the order quantity based on the future spot price of consumption commodities.  Compared to the simple wholesale price contract, a win-win situation can be achieved under the flexible supply contract when the manufacturer’s postponed processing cost is lower than a threshold.  However, under this flexible supply contract the retailer may suffer from the commodity price volatility even if she does not procure the commodities directly.  We further investigate how the risk-averse retailer conducts mean-variance financial hedging by purchasing consumption commodity futures contracts.  We formulate the problem as a dynamic programming model and derive a closed-form time-consistent financial hedging policy.  Through numerical experiments, we show that the commodity price risk from the manufacturer to the retailer is effectively mitigated with the hedging, and the benefits of the flexible supply contract are maintained. 

Keywords: spot market, futures contracts, financial hedging, demand forecast update
