Abstract: We study a two-echelon supply chain consisting of a supplier and a retailer, where the supplier uses a simple and easily implementable incentive scheme of making a side payment to influence the retailer’s ordering plan. The supplier makes a take-it-or-leave-it offer to the retailer in the form of a menu of contracts, each consisting of a procurement plan plus a side payment. The retailer, who possesses private information about customer demand and his cost parameters, either accepts one of the contracts or imposes his own optimal plan. We formulate the supplier’s problem of designing optimal contracts with the assumption that the retailer’s outside option depends on his private information. Taking into account the retailer’s reaction to the proposed offer, the supplier faces a nested (bi-level) optimization problem, which we transform into a single-level mixed integer programming variant. In our analysis, we use a network interpretation for the set of incentive constraints and show several structural properties of optimal contracts. This enables us to considerably reduce the set of incentive constraints and to find optimal values of side payments. Our findings regarding the possible behavior of the opportunistic retailer deviate from those of previous studies as a result of considering more realistic assumptions.
