This paper shows that accounting for variation in mistakes can be crucial for welfare analysis. Focusing on consumer underreaction to not-fully-salient sales taxes, we show theoretically that the efficiency costs of taxation are amplified by differences in underreaction across individuals and...

Taxes change behavior. But how does this change arise? In traditional economic models, change is achieved through the price channel: assuming all else is held constant, taxes increase prices and thus decrease demand. However, the assumption that all else is held constant may be violated in the...

Imperfect information and inattention to energy costs are important potential justifications for energy efficiency standards and subsidies. We evaluate these policies in the lightbulb market using a theoretical model and two randomized experiments. We derive welfare effects as functions of...
