Explaining the Border Effect: The Role of Exchange Rate Variability, Shipping costs, and Geography

Abstract

This paper exploits a three-dimensional panel data set of prices on 27 traded goods, over 88 quarters, across 96 cities in the US and Japan. We show that a simple average of good-level real exchange rates tracks the nominal exchange rate well, suggesting strong evidence of sticky prices. Focusing on dispersion in prices between city-pairs, we find that crossing the US-Japan "Border" is equivalent to adding as much as 43,000 trillion miles to the cross-country volatility of relative prices. We turn next to economic explanations for this so-called border effect and to its dynamics. Distance, unit-shipping costs, and exchange rate variability, collectively explain a substantial portion of the observed international market segmentation. Relative wage variability, on the other hand, has little independent impact on segmentation.
