Move orders in contests: Equilibria and winning chances

Abstract

This paper studies general two-player sequential-move competitions, accommodating a full spectrum of Tullock contest technology and contestants' asymmetry. We provide necessary and sufficient conditions for a preemptive equilibrium to prevail in both strong-lead and weak-lead contests, and discover a characteristic equation to pin down the players' effort ratio (which fully determines their winning chances) and their effort levels when a non-preemptive equilibrium prevails. We find that while the strong player always has a higher winning chance when moving first, simultaneous moves sometimes maximize the weak player's winning odds. We further allow the move orders endogenous through winning-odd-maximizing coaches' independent choices.
