French Abstract: Politique de divulgation dans des concours à la Tullock quand l'entrée est stochastique et asymétrique. On examine comment une politique de divulgation ou non du nombre des participants à un concours peut être optimisée pour donner des incitations aux participants quand...

This paper proposes a multi-winner noisy-ranking contest model. Contestants are ranked in a descending order by their perceived outputs, and rewarded by their ranks. A contestant's perceivable output increases with his/her autonomous effort, but is subject to random perturbation. We establish,...

This paper examines the variation in total effort expended by participants when prizes are awarded in a grand contest as opposed to a number of subcontests. When contestants are homogeneous, under a mild and plausible condition (regular contest technology), a grand contest generates more effort...

This paper derives the effort-maximizing contest rule and the optimal endogenous entry in a context where potential participants bear fixed entry costs. The organizer is allowed to design the contest under a fixed budget with two strategic instruments: he sets the value of the prize purse, and...

This paper investigates the optimal (effort-maximizing) structure of multi-stage sequential-elimination contests. We allow the contest organizer to design the contest structure using two instruments: contest sequence (the number of stages, and the number of contestants remaining after each...

This paper investigates the competitive effect of cross-shareholdings in winner-take-all all-pay auctions with two asymmetric bidders. We show that cross-shareholdings may paradoxically create a “pro-competitive” effect and elicit more effort than a standard contest without cross-ownership....

This paper investigates whether a contest organizer should disclose private information about bidders’ abilities in a multi-prize all-pay auction. Bidders’ abilities are randomly distributed and observed by the contest organizer; the organizer decides whether to disclose this information...

This paper proposes a multi-prize “reverse” nested lottery contest model, which can be viewed as the “mirror image” of the conventional nested lottery contest of  Clark and Riis (1996a). The reverse-lottery contest model determines winners by selecting losers based on contestants’...

This paper investigates the optimal (effort-maximizing) structure of multi-stage sequential-elimination contests with pooling competition in each stage. We allow the contest organizer to design the contest structure in two arms: contest sequence (the number of stages, and the number of remaining...
