We propose a decomposition of the border effect in international trade by controlling for differences in competition in local markets. An extension of the Hotelling (1929) model shows that the availability of local substitutes increases price dispersion and biases the estimation of the border...

We assess price dispersion in retail markets and its sources over time. Using a product-detailed price database, we document a consistent divergence of prices over time in retail markets in Uruguay: price dispersion increased by 3.1% in fifteen years. Next, we analyze microeconomic and...

We offer a new mechanism for prices to deviate from the Law of One Price. If stores differ in the varieties offered in a given product category, prices diverge more often regardless of distance. A simple extension to the Hotelling (1929) explains this result. To have one difference in variety in...
