Abstract:
We reexamine the evidence for border effects in deviations from the law of one price, using data for consumer prices from Canadian and U.S. cities. The study parallels Engel and Rogers (1996), except that this study uses actual price data rather than price index data. We find evidence of border effects both in the levels of prices and the percentage change in prices. Even accounting for distance between cities and relative population sizes, we find that the absolute difference between prices in the U.S. and Canada in our data (annual from 1990 to 2002) is greater than seven percent. This difference exists among tradables and nontradables, though for some categories of tradables (clothing and durables) the difference is smaller. The findings are similar for annual changes, though the magnitude is smaller: the border accounts for a difference in 1.5 percent in annual (log) price changes. Relative population sizes and distance are helpful in explaining price level differences (between Canadian and U.S. cities) for traded goods, but are less helpful in explaining price level differences for nontraded goods or for accounting for differences in price changes for either traded or nontraded goods.

Abstract:
Using consumer price indexes from cities in the U.S., Canada and Mexico, we estimate the "border effect" on U.S.-Mexican relative prices and find that it is nearly an order of magnitude larger than for U.S.-Canadian prices. However, during a very stable sub-period in Mexico (May 1988 to November 1994), the "width" of the U.S.-Mexican border falls dramatically and becomes approximately equal to the U.S.-Canadian border. We then show that when consideration is limited to cities lying geographically very close to the U.S.-Mexican border--San Diego, Los Angeles, Houston, Dallas, Tijuana, Mexicali, Juarez, and Matamoros--the border width falls compared to that estimated with the full sample of U.S. and Mexican cities, but falls only very slightly. We also present evidence that the border effect in U.S.-Mexican prices is not primarily due to the border effect in U.S.-Mexican wages. Finally, using the prices of 276 highly dis-aggregated goods and services, we estimate the variability of relative prices of different items within Mexican cities. This measure of relative price variability declines during the stable peso sub-period, but by less than the decline in nominal and real (i.e., CPI-based) exchange rate variability. Our results are strong evidence of a "nominal border effect" in relative prices within NAFTA, but also indicate that real side influences are important.
