We consider a best-of-three Tullock contest between two ex-ante identical players. An effort-maximizing designer commits to a vector of player-specific biases (advantages or disadvantages). In our benchmark model the designer chooses victory-dependent biases (i.e., the biases depend on the...

We aim at characterizing which kind of functions could be explained (rationalized) as the best reply of payoff-maximizing agents in contests for a fixed prize. We show that the rationalizability strongly differs between Decisive Contests, where the prize is allocated with certainty, and Possibly...

In noisy contests where only the winners entry will eventually be implemented, the suitable objective is to maximize the quality of the entry of the expected winner. We compare the optimal set of rules in contests under such an objective to the one under maximization of the sum of contestants'...

The experimental evidence on contests often reports overspending of contest participants compared to the theoretical Nash equilibrium outcome. We show that a standard level-k model may rationalize overspending in contests. This result complements the existing literature on overspending in...
