Abstract: This article presents the first assessment of domestic market integration in Brazil using the law of one price. The law of one price is tested using two panel unit root methodologies and a unique data set comprising price indices for 51 products across 11 metro-areas. We find that the law holds for most tradable products and, not surprisingly, nontradable products are found to be less likely to satisfy the law of one price. While these findings are consistent with evidence found for other countries, price convergence occurs very slowly in Brazil, suggesting relatively limited domestic market integration.

KEYWORDS: Law of one price, panel cointegration, domestic market integration JEL CLASSIFICATION: E31, F15, O54

Data and codes

  1. (STATA file) consolidates all the CSV files into a single panel, creates CPI indices for all cities and products, and calculates time-effect treated series for panel unit root analysis
  2. uroots.prg (Eviews program) runs two panel unit roots tests (LLC and IPS) and individual ADF equations for each city-product pair.
You can’t perform that action at this time.
