Abstract:  
We study optimal contest design when two asymmetric players compete in a complete-information all-pay-auction contest with multi-dimensional favoritism. The favoritism can take the form of a player being given a head-start advantage ("additive bias"), or an effectiveness advantage which enhances each unit of effort ("multiplicative bias") expended by a player. We solve for the optimal contest for a designer who would like to achieve each of the following objectives: maximizing the total effort, maximizing the total score, maximizing the highest effort by a single player, and maximizing the winner’s effort. We find a single necessary "fairness condition" under each of the four objectives of the designer, and further show that the condition is robust to non-linear forms of favoritism. Our findings contribute to a better understanding of the optimal unfair contests, and generalize some of the results in the previous literature with single-dimensioned unfairness.
