Recording industry revenue has fallen sharply in the last 3 years, and some—but not all—observers attribute this to file sharing. We collect new data on albums obtained via purchase and downloading, as well as consumers’ valuations of these albums, among a sample of U. S. college students in 2003. We provide new estimates of sales displacement induced by downloading, using both ordinary least squares and an instrumental variables approach with access to broadband as a source of exogenous variation in downloading. We find that each album download reduces purchases by about. 2 in our sample, although possibly by much more. Our valuation data allow us to measure the effects of downloading on welfare as well as expenditure in a subsample of University of Pennsylvania undergraduates, and we find that downloading reduces their per capita expenditure (on hit albums released 1999–2003) from 126 to 101 but raises per capita consumers’ surplus by 70.
