Abstract of the Paper:
This paper studies the optimal design of contestants' move order in a general two-player Tullock contest, allowing for a full range of the contest's accuracy (denoted by r) and players' asymmetry. We first provide a complete equilibrium analysis for sequential-move Tullock contests. We find that an equilibrium is either interior (both players are active) or preemptive (the follower is inactive). In a strong-lead sequential contest, there is a preemptive (resp. interior) equilibrium when the contest is sufficiently accurate (resp. noisy); in a weak-lead sequential contest, there can be a preemptive equilibrium if the players' asymmetry level is low. Using the equilibrium analysis, we investigate an effort maximizing designer's optimal choice among three contest formats: simultaneous, weak-lead, and strong-lead sequential contests. We find that a strong-lead sequential contest is optimal if the contest is sufficiently noisy (including r=1), but it is dominated by at least one other format otherwise. Surprisingly, a weak-lead sequential contest can be optimal if the weak leader chooses to preempt the strong follower in equilibrium. This paper provides a rationale for the diversity of contest designs observed in practice.
