报告摘要:

I investigate the optimal design of contests when contestants have both private information and convex effort costs. The designer has a fixed prize budget and her objective is to maximize the expected total effort. I first demonstrate that it is always optimal for the designer to employ a grand static contest with as many participants as possible. Further, I identify a sufficient and necessary condition for the winner-takes-all prize structure to be optimal. When this condition fails, the designer may prefer to award multiple prizes of descending sizes. I also provide a characterization of the optimal prize allocation rule for this case. Lastly, I illustrate how the optimal prize distribution evolves as contest size grows: the prize distribution first becomes more unequal until the optimal level of competition intensity is obtained and then becomes less unequal to maintain the optimal intensity.
