【摘要】
In recent decades, manufacturers have been reliant on giant retailers or e-tailers for distributing their products. As evolvement, some retailers have started demanding for a Profit-Margin-Guarantee contract (PMG contract), under which a manufacturer has to ensure that its retailer’s profit margin is not less than a certain level (PMG rate). Conventional wisdom suggests that PMG contract will induce a life-or-death struggle for the manufacturer, and a retailer with PMG contract can gain competitive edge over his competitors. This study investigates the strategic impacts of PMG contract in a competitive environment. We consider a supply chain consisting of one manufacturer and two competing retailers, in which the manufacturer has signed a PMG contract with one retailer (signed retailer) but not with the other retailer (unsigned retailer). Our analyses show that in response to the PMG contract, the manufacturer can adopt a “passive pricing” strategy (in terms of the production cost) to strategically trigger or void the PMG contract. For which reason, interestingly, the manufacturer (resp. the signed retailer) would not always hurt (resp. benefit) from the PMG contract. Depending on the production cost and the PMG rate, PMG contract may yield the win-win, win-lose, lose-win and lose-lose outcomes for the manufacturer and the signed retailer. Moreover, the unsigned retailer may enjoy a “free-riding” effect generated by the PMG contract, making her better off even under the unfavorable competitive situation. Nevertheless, PMG contract cannot yield a win-win-win outcome for all the firms whereas a lose-lose-lose outcome may arise in certain conditions.
