We study equilibrium in a multistage race in which players compete in a sequence of simultaneous move component contests. Players may win a prize for winning each component contest, as well as a prize for winning the overall race. Each component contest is an all-pay auction with complete...

We study the incentives to share private information ahead of contests, such as markets with promotional competition, procurement contests, or R&D. We consider the cases where firms have (i) independent values and (ii) common values of winning the contest. In both cases, when decisions to share...

Many contests, such as innovation races or litigation, often involve reimbursement of expenses. This study examines optimal reimbursement schemes in two-player Tullock contests, analyzing four reimbursement structures: external and internal mechanisms targeting the contest winner or loser. We...

We find the sufficient conditions for the existence of multiple equilibria in Tullock-type contests and show that asymmetric equilibria may arise even under symmetric prize and cost structures. We also identify contests in the literature where multiple equilibria exist under reasonably weak...
