Range contracts: Risk sharing and beyond

We introduce and study the range contract, which allows a buyer to procure from a supplier at a prescribed price any amountwithin a specified range. In return, the supplier is compensated up front for thewidth of the rangewith a range fee. This fee canbe viewed as the buyer tradingmonetary value for reduceduncertainty. The range contract generalizes and unifiesmany common contracts, such as fixed-price, JIT, option, and quantityflexibility contracts. The parameters that maximize the expected profit of the centralized supply chain are derived here and are shown to crucially depend on production flexibility. We also study here the buyer’s expected profit-maximizing range endpoints as a function of the pricing parameters of the contract. Using the buyer’s optimal range, we demonstrate how the supplier can set the contract’s pricing parameters so as to maximize the supplier’s expected profit for a uniform distribution of demand. We provide computational evidence, for uniformly distributed demand, that the range contract allows the optimal decentralized supply chain to attain significant reductions in standard deviation of profit in exchange for moderate reductions in expected value of profit. We further demonstrate computationally that both the buyer and supplier can benefit simultaneously, attaining higher risk-adjusted profits than the centralized supply chain. © 2015 Elsevier B.V.
