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...

Using a two-player Tullock-type contest we show that intuitively and structurally different contests can be strategically equivalent. Strategically equivalent contests generate the same best response functions and, as a result, the same equilibrium efforts. However, strategically equivalent...

We study experimentally the effects of cost structure and prize allocation rules on the performance of rent-seeking contests. Most previous studies use a lottery prize rule and linear cost, and ?nd both overbidding relative to the Nash equilibrium prediction and signi?cant variation of efforts,...

We study experimentally the effects of cost structure and prize allocation rules on the performance of rent-seeking contests. Most previous studies use a lottery prize rule and linear cost, and find both overdissipation relative to Nash equilibrium prediction and significant variation in...

We investigate the effects of Partner and Stranger matching in contest experiments and find no difference in the level or distribution of bids across matching protocols. However, demographic and individual strategy effects are different with different matching. Hence, unless one is interested in...

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 use a Tullock-type contest model to show that intuitively and structurally different contests can be strategically and revenue equivalent to each other. We consider a two-player contest, where outcome-contingent payoffs are linear functions of prizes, own effort, and the effort of the rival....

We construct a generalized Tullock contest under complete information where contingent upon winning or losing, the payoff of a player is a linear function of prizes, own effort, and the effort of the rival. This structure nests a number of existing contests in the literature and can be used to...
