Sumo wrestling tournaments typically have 66 wrestlers. Each wrestles 15 matches. A wrestler who has a winning record (eight wins or more) is guaranteed to rise in the official rankings; a wrestler with a losing record falls in the rankings.

Question 2

Answer to Question 1

Mark Duggan and Steven Levitt find that in these situations, the wrestler who has won seven matches so far is much more likely to win than we would expect. They interpret this is as evidence of moral hazard. Whether or not a wrestler is trying hard to win a match is private information. The two wrestlers in our example could agree to a bribe since the value of winning is much greater for B than for A but the effort they make to win are hidden actions. They find little support for an alternative explanation that B is more likely to win because he is more highly motivated.
