Cross-border production sharing and exchange-rate sensitivity of Mexico's trade balance

Increasing patterns of international trade occur in the form of cross-border production sharing -- the dispersion of separate blocks of an integrated production process across different nations. In the case of ‘standard’ or ‘ordinary’ trade, imports are destined for use in the importing country, and exports are largely produced within the country. However, with production sharing, imported parts and components are destined for inclusion in the country's exports. A depreciation of a nation's currency raises its exports. At the same time, imported components become more expensive, which partly offsets the expansionary effect of the depreciation on exports. Using a simple theoretical framework, this paper shows that production networks lower the sensitivity of a country's trade balance to changes in exchange rates. The empirical examination finds Mexico's Maquiladora trade balance to be unresponsive to changes in both, its real effective as well as its real peso-dollar rates, while that for non-Maquiladora category is significantly responsive, in confirmation with the theorized hypothesis.
