Measuring International Trade Costs

The costs of international trade have become an increasingly important item in trade negotiations (under the heading ‘trade facilitation’) and element of trade theory, but definition and measurement of trade costs remain in their infancy. This paper argues that the most conceptually appropriate measure is the gap between cost‐insurance‐freight (cif) and free‐on‐board (fob) values of traded goods, but that this must be measured on a consistent volume of trade. Such data are only available for a few countries. We calculate cif–fob gap values for the three largest trading nations that report such data (Australia, Brazil and the USA). These values provide plausible estimates of ad valorem trade costs for the three importing countries and for all countries’ exports. The estimates indicate that although trade costs have fallen over the last two decades, average trade costs now exceed the average tariff rate on imports into the USA and Australia. Country rankings by the cif–fob gap values differ significantly from those by commonly used proxies for trade costs, such as the indicators of time and cost in the World Bank’s Doing Business database, and analysis based on such proxies is likely to produce misleading results.
