Contest functions (alternatively, contest success functions) determine probabilities of winning and losing as a function of contestants’ eort. They are used widely in many areas of economics that employ contest games, from tournaments and rent-seeking to conflict and sports. We first examine...

Contest functions (alternatively, contest success functions) determine probabilities of winning and losing as a function of contestants' effort. They are used widely in many areas of economics that employ contest games, from tournaments and rent-seeking to conflict and sports. We first examine...

We explore theoretical foundations and issues in the empirical estimation of conflict technologies. Such technologies are probabilistic choice functions that depend on the military capacities of adversaries, where the military capacities themselves depend on economic inputs via ordinary...

We survey empirical studies on the development and effects of increased computerization across equity, foreign exchange, derivatives, and fixed-income markets. While the changes in the trading process due to computerization in less liquid markets such as the corporate bond market have been...

We examine the behavior of call options surrounding the underlying stock's ex-dividend date. The evidence is inconsistent with the predictions of a rational exercise policy; a significant fraction of the open interest remains unexercised, resulting in a windfall gain to option writers. This...

In this article, I analyze a class of contest success functions (CSFs) that satisfy Luce's Choice Axiom. I show that the functional forms of these CSFs can be fully identified if they are characterized by a partial differential equation (PDE), which has several intuitive economic...

In the current FIFA penalty shootout mechanism, a coin toss decides which team will kick first. Empirical evidence suggests that the team taking the first kick has a higher probability to win a shootout. We design sequentially fair shootout mechanisms such that in all symmetric Markov-perfect...
