Main Focus

Wu et al. (2002) is arguably the earliest research on the integration of supply contract and spot market. They consider a setting with one seller and one or more buyers in a capital-intensive industry. In addition to the long-term bilateral contract between the seller and the buyers, both of them are allowed to sell excess capacity or purchase necessary outputs from the spot market to satisfy the demand. In their model, the option-type contract has two-part fee structure, the unit reservation cost and the unit execution cost if the capacity is called. Optimal solutions are derived in a von Stackelberg game, in which the seller’s optimal bidding strategy and the buyers’ optimal contracting strategy are both determined. Based on transaction cost economics (TCE), Kleindorfer and Wu (2003) provide a general analytic framework and survey the research and practice on the use of options in the B2B markets. Since then, many studies have been done to investigate the effect of portfolio procurement on supply chain performance. Together, they strive to address the following questions.
