Abstract

We characterize the optimal procurement contract in a setting where a supplier has privileged knowledge of the quality of a public signal about his production costs. The optimal contract exhibits important differences with standard contracts in adverse selection settings. For instance, the contract induces output both above and below first-best levels. Furthermore, the induced output may not vary with the realized public signal unless the signal quality is sufficiently pronounced. In addition, output may increase as expected costs increase.
