Consumer Arbitrage Across a Porous Border Chandra, Ambarish; Head, Keith; Tappata, Mariano

Abstract

National borders, including the easily crossed US-Canada border, have been shown to separate markets and sustain price differences. The resulting arbitrage opportunities vary temporally with the exchange rate and cross-sectionally with travelers' distance to the border. We estimate a structural model of the border crossing decision using data on the location of Canadian crossers and their date of travel. Price differences motivate cross-border travel; a 10% exchange rate appreciation raises the average crosser's welfare by 2.1%. Distance strongly inhibits crossings, with an implied cost of $0.9 per mile. These costs prevent consumers from fully arbitraging price differences, leading to partial segmentation. An earlier version of this paper was entitled "The Economics of Cross-Border Travel."
