Abstract

Recent research suggests that trade costs have a strong influence on the pattern of specialization and trade, but there is limited empirical research on the determinants of trade costs. The existing literature identifies a range of barriers that separate nations, but then typically focuses only on transport costs. Although communication costs figure prominently in intuitive explanations and casual observations, they have played little role in the formal analysis of trade costs. Fink, Mattoo, and Neagu seek to examine whether this neglect matters, and whether the inclusion of the magnitude and variation of communication costs across partner countries can add value to existing explanations of the pattern of trade.

The authors develop a simple multi-sector model of "impeded" trade that generates testable hypotheses in a gravity-type estimation framework. The main proxies for bilateral communication costs are the per-minute country-to-country calling prices charged in the importing and exporting countries. The use of bilateral variations in prices yields estimates that are superior to the ones obtained from country-specific measures of communication infrastructure used in previous studies. The authors find that international variations in communication costs indeed have a significant influence on bilateral trade flows¬óboth at the aggregate level and for most individual sectors disaggregated according to the 2-digit SITC classification.

Since information and communication needs are likely to be much greater for differentiated goods, the authors test whether trade in these products is more sensitive to variations in the costs of communication. Using the Rauch classification of product heterogeneity, the estimates suggest that the impact of communication costs on trade in differentiated products is as much as one-third larger than on trade in homogenous products. Finally, the authors verify, to the extent possible, that the significance of communication costs is not driven by their endogeneity or by omitted variables.

This paper - a product of Trade, Development Research Group - is part of a larger effort in the group to assess the implications of liberalizing trade in services.
