1 Measuring Border Crossing Costs and their Impact on Trade Flows: The United States-Mexican Trucking Case

This article presents the economic implications of the costs and times of crossing the border between the United States and Mexico. We measure the microeconomic impact of the inefficiencies of crossing the U.S.-Mexican border on shippers. We identify and explain the institutional factors and vested interests that permit cross-border inefficiencies to appear and endure and estimate the costs of these inefficiencies associated with cross-border movements between the U.S. and Mexico. Inefficiencies here are defined as money paid by shippers for charges for non-essential border-crossing services. These inefficiencies not only cost exporters and importers time and money— they also cause welfare losses to the entire economy because of the distortions they introduce to consumption and sourcing decisions. In order to measure both the primary and secondary impacts of these nontariff barriers, we use the General Trade Analysis Project-GTAP- model to simulate the removal of iceberg trade costs equal in magnitude to the measured nontariff barriers at the U.S.-Mexican border. The measures of inefficiency at the U.S.-Mexican border come from detailed border surveys and data analysis performed by Haralambides and Londoño-Kent (“Impediments to Free Trade: The Case of Trucking and NAFTA in the U.S.-Mexican Border”, mimeo, 2002). These measures of distortion are then used to calibrate an iceberg tariff within the GTAP model. We aggregate th
