PB - National Bureau of Economic Research N1 - November 2018; Hardcopy version available to institutional subscribers N2 - We introduce a simple method of recovering attention costs from choice data. Our method rests on a precise analogy with production theory. Costs of attention determine consumer demand and consumer welfare just as a competitive firm's technology determines its supply curve and profits. We implement our recovery method experimentally, outline applications, and link our work to the broader literature on inattention and mistaken decisions UR - https://www.nber.org/papers/w25224 UR - http://dx.doi.org/10.3386/w25224 ER -
