陳礴教授將主要介紹在需求不確定情形下購(gòu)買(mǎi)現(xiàn)貨和期權(quán)的決策問(wèn)題，采用博弈論的分析方法，揭示競(jìng)爭(zhēng)性的供應(yīng)商和采購(gòu)方的利益分配關(guān)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.
