题目:Feedback and Favoritism in Sequential Elimination Contests

摘要:this paper studies the optimal design of sequential-elimination contests. The contest proceeds in two stages, with N contestants participating in the first stage and M<N of them surviving the elimination and competing for the actual prize in the finale. We explore the optimal feedback policy for the contest, i.e., whether the contest designer should publicize contestants' interim ranking prior to the finale. We show that the optimum depends on the objective function for contest design. The contest designer prefers opacity---i.e., concealing the information---if she aims to maximize total effort in the contest. However, transparency---i.e., publicizing contestants' interim ranking---may outperform if the designer maximizes the expected winner's total effort along the hierarchical ladder. We further consider an extended model in which the designer can place different weights on finalists' effort entries in the contest success function based on their interim ranks. The baseline model is thus a special case of the extended one, because outright elimination is equivalent to placing excessively small weights on bottom-ranked contestants. We show that with endogenously chosen biases, opacity outperforms in generating total effort, while transparency emerges as the optimum when the expected winner's total effort is at stake. These results also yield ample practical implications.
