Abstract :Models based on costs of switching beliefs, for example, due to inat-tention, are related to hypothesis tests and vice versa. Specifically, for aninference problem with a penalty for mistakes and for switching the in-ferred value a band of inaction is optimal. We show this band is equivalent to a confidence interval, and therefore to a two-sided hypothesis test.
