Health-maximizing and welfare-maximizing behaviors can be at odds, especially among disadvantaged groups, generating health disparities. We estimate a lifecycle model of medication and labor supply decisions using data on HIV-positive men. We evaluate an effective HIV treatment innovation that...

This paper develops a new approach that combines firm margins, market-level industry data and a static demand model to construct sets containing unbiased estimates of long-run price elasticities for storable good industries. It obviates the need to solve the consumer's value function and can be...

This note presents some simple, direct tests for search and dynamic demand behavior in retail gasoline markets. We exploit a unique market-level dataset that allows us to directly measure search intensity with daily web traffic data from a gasoline price reporting website, and perfectly measure...
