报告内容摘要

Manufacturers' production capacity may be disrupted due to a pandemic outbreak, trade frictions, military conflicts, etc. This paper develops a two-period supply chain model with supply disruption risk in the second period to investigate firms' inventory decisions and the manufacturer's commitment strategies. We consider a manufacturer's three strategies: no commitment (NC), price commitment (PC), and inventory commitment (IC). Under each strategy, we investigate inventory holding between the two firms. Furthermore, comparing the three strategies leads to the manufacturer's optimal strategy. Supply disruption risk drives distinctive results compared to the case without supply risk. First, the retailer may have two opposite motives for inventory holding: inventory-building motive and inventory-shifting motive (i.e., shifting inventory to the manufacturer), where the latter motive cannot exist without supply risk. Strategy PC suppresses both motives and IC suppresses only the inventory-shifting motive. Second, under strategy PC, the retailer never holds inventory. Under strategies NC and IC, the manufacturer's optimal inventory is zero without supply risk, but can be either positive or zero with supply risk; for high holding cost and disruption risk, only the manufacturer holds inventory, whereas for low holding cost and disruption risk, only the retailer holds inventory. Furthermore, the manufacturer's inventory can decrease as supply risk increases. Third, in terms of the choice among the three strategies, the manufacturer (weakly) prefers IC to the other two strategies. However, only for low holding cost and high disruption risk does IC perform strictly better. In this case, the manufacturer should reveal its inventory information to implement strategy IC. PC can perform either better or worse than NC. This is in sharp contrast with the literature without supply risk that shows PC never outperforms NC.
