Many price indices must be constructed without quantity data at the elementary level. We show that for some consumer goods in the United States and other countries, one can approximate expenditure shares using weights derived from the retail distribution of sellers. These weights are based on...

We examine the price and variety of products at the barcode level in cities within China and the United States. In both countries, there is a greater variety of products in larger cities. But in China, unlike the United States, the prices of products tend to be lower in larger cities. We...

Abstract We examine the price and variety of products at the barcode level in cities within China and the United States. In both countries, there is a greater variety of products in larger cities. But in China, unlike the United States, the prices of products tend to be lower in larger cities....

We examine the price and variety of a sample of consumer goods at the barcode level in cities within China. Unlike the United States, in China the prices of goods tend to be lower in larger cities. We explain that difference between the countries by the more uneven spatial distribution of...

Many price indices must be constructed without quantity data at the elementary level. We show that for some consumer goods in the United States and other countries, one can approximate expenditure shares using weights derived from the retail distribution of sellers. These weights are based on...

We examine the relationship between large firms and the rising profit share in a model that features oligopolistic competition and consumer heterogeneity. Conditional on the sales distribution, the presence of consumer heterogeneity increases the profit share because it increases firm-level...

We study the market response to firm-specific shocks in a natural experiment setting. In 2006, a boycott of Danish products in several Arab countries was devastating for Danish cheese products firms. In Saudi Arabia their market share collapsed from 16.5% in January to below 1% in March and...
