Improving Supply Chain Performance and Managing Risk Under Weather-Related Demand Uncertainty

This paper considers a manufacturer-retailer supply chain for a seasonal product whose demand is weather-sensitive. The retailer orders from the manufacturer (supplier) prior to the selling season and then sells to the market. We examine how a manufacturer can structure a weather-linked rebate to improve his expected profit. The proposed class of rebate contracts offers several advantages over many other contract structures, including no required verification of leftover inventory and/or markdown amounts, and no adverse effect on sales effort by the retailer. We provide a thorough analysis of the manufacturer’s and retailer’s decisions in this context. We show that the weather-linked rebate can take many different forms, and this flexibility allows the supplier to design contracts that are Pareto-improving and/or limit his risk in offering the contract and the retailer’s risk in accepting it. For weather rebates with certain characteristics, the manufacturer can fully hedge his risks of offering a weather rebate by paying a risk premium; we show how this can be accomplished. We also show that the basic structural results extend to more general settings, including situations where the two parties are concerned about risk and where they can set prices.
