Abstract Buyers have two levers to enhance their supply base performance: fostering supplier competition and inducing supplier improvement effort. The relationship between the two levers drives supply base design. We study a buyer sourcing from two potential suppliers that exert cost‐reduction efforts. We show that supplier competition can affect supplier effort in either way, depending on the effort observability: When supplier effort is unobservable, competition always leads to lower effort, as competition reduces a supplier's return of investment in improvement (negative incentive). When supplier effort is observable, however, competition also induces a supplier to improve (positive incentive), as effort increases the probability of winning the competition. Overall, therefore, supplier competition may encourage suppliers to exert higher effort, when the effort is observable and the effort disutility is relatively low. We characterize the buyer's optimal supply base design, namely, the choice between sole and dual sourcing. Furthermore, the comparison between the unobservable and observable cases reveals a detrimental effect of supplier effort information: Observability of supplier effort makes the buyer worse off, as it allows the buyer to better extract supplier profits in procurement, in turn reducing suppliers' incentive to exert upfront efforts. We relate this result to procurement strategies in practice. All are welcome!
