We compile a new database of grocery prices in Argentina. We find uniform pricing both within and across regions—i.e., prices almost do not vary within the stores of a chain. In line with uniform pricing, prices in stores of chains operating in one region react to changes in regional employment while prices in multiregion chains do not. Using a quantitative regional model with multiregion firms and uniform pricing, we find a one-half smaller elasticity of prices to a regional than an aggregate shock. This result highlights that some caution may be necessary when using regional shocks to estimate aggregate elasticities. (JEL D22, L11, L81, O14, O18, R32)
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.
