Performance feedback in competitive product development
研究了竞争性产品开发中绩效反馈对参与者和作品质量的影响，发现反馈虽降低参与度但提升后续作品质量，总体上增加了高质量创意的数量，对寻求创新的管理者有价值。
Performance feedback is ubiquitous in competitive settings where new products are developed. This article introduces a fundamental tension between incentives and improvement in the provision of feedback. Using a sample of 4294 commercial logo design tournaments, I show that feedback reduces participation but improves the quality of subsequent submissions, with an ambiguous effect on high‐quality output. To evaluate this trade‐off, I develop a procedure to estimate agents' effort costs and simulate counterfactuals under alternative feedback policies. The results suggest that feedback on net increases the number of high‐quality ideas produced and is thus desirable for a principal seeking innovation.
