Fatter or fitter? On rewarding and training in a contest

Abstract

Competition between heterogeneous participants leads to low-effort provision in contests. A principal can divide her fixed budget between skill-enhancing training and the contest prize. Training can reduce heterogeneity, increasing effort. It also reduces the contest prize, making effort fall. We set up an incomplete-information contest with heterogeneous players and show how this trade-off is related to the size of the budget of an effort-maximizing principal. A selection problem arises implying a cost associated with a win by the inferior player. The principal has a larger incentive to train the laggard, reducing the prize on offer.
