%S TSE Working Paper %A Yeon-Koo Che %A Elisabetta Iossa %A Patrick Rey %T Prizes versus contracts as incentives for innovation %X Procuring an innovation involves motivating a research effort to generate a new idea and then implementing that idea efficiently. If research efforts are unveriable and implementation costs are private information, a trade-off arises between the two objectives. The optimal mechanism resolves the trade-off via two instruments: a cash prize and a follow-on contract. It primarily uses the latter, by favoring the innovator at the implementation stage when the value of the innovation is above a certain threshold and handicapping the innovator when the value of the innovation is below that threshold. A cash prize is employed as a supplementary incentive only when the value of innovation is sufficiently high. These features are consistent with current practices in the procurement of innovation and the management of unsolicited proposals. %K Contract rights %K Inducement Prizes %K Innovation %K Procurement and R&D %B TSE Working Paper %V 16-695 %D 2016 %C Toulouse. %I TSE Working Paper %L publications22358
