Over the last 15 years, individual households have concentrated their spending on a few preferred products. However, this is not driven by “superstar” products capturing larger market shares. Instead, households increasingly purchase different products from each other. As a result, aggregate spending concentration has decreased. We develop a model of heterogeneous household demand and use it to conclude that increasing product variety drives these divergent trends. When more products are available, households select products better matched to their tastes. This delivers welfare gains from selection equal to about half a percent per year in the categories covered by our data. (JEL D12, D91, E21, L66)
期刊介绍:
American Economic Journal: Macroeconomics focuses on studies of aggregate fluctuations and growth, and the role of policy in that context. Such studies often borrow from and interact with research in other fields, such as monetary theory, industrial organization, finance, labor economics, political economy, public finance, international economics, and development economics. To the extent that they make a contribution to macroeconomics, papers in these fields are also welcome.
