摘要

我们编制了一个关于阿根廷食品价格的新数据库。我们发现区域内和区域间的价格都是统一的。在美国，同一家连锁店的价格几乎没有变化。根据统一定价，在一个地区经营的连锁店的价格会随着区域就业的变化而变化，而在多地区连锁店的价格则不会。通过使用多地区企业和统一定价的定量区域模型，我们发现价格对区域的弹性比总冲击小一半。这一结果强调，在使用区域冲击来估计总弹性时，可能需要谨慎一些。(jj22, 11, 81, 14, 18, 32)

Macroeconomic Implications of Uniform Pricing

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.
