Cricket Interruptus: Fairness and Incentive in Interrupted Cricket Matches

Abstract

We present a new adjustment rule for interrupted cricket matches that equalizes the probability of winning before and after the interruption. Our proposal differs from existing rules in the quantity preserved (the probability of winning) and also in the point at which it is measured (the time of interruption). We claim this is both fair and free of incentive effects. We give several examples of how our rule could have been applied in past matches including some in which the ultimate result might have been different.
