陈礴教授将主要介绍在需求不确定情形下购买现货和期权的决策问题，采用博弈论的分析方法，揭示竞争性的供应商和采购方的利益分配关系。

When a firm faces an uncertain demand, it is common toprocure supply using some type of option in addition to spot purchases. Atypical problem of this type involves capacity being purchased in advance, witha separate payment made that applies only to the part of the capacity that isneeded. We consider a discrete version of this problem in which competingsuppliers choose a reservation price and an execution price for blocks ofcapacity, and the buyer, facing known distributions of demand and spot price,needs to decide which blocks to reserve. We show how to solve the buyer'scombinatorial optimization problem efficiently and prove that suppliers can dono better than offer blocks at execution prices that match their costs, makingprofits only from the reservation part of their bids. Furthermore, we show thatin an equilibrium the buyer selects the welfare maximizing set of blocks, whichis also group strategy-proof.
