Abstract: Abstract To examine how changes in relative national prices affect trade flows, this study estimates the impact of changes in industry-specific effective real exchange rates on industry-level trade balances, exports, and imports. We analyze the variations in industry-specific intra-industry trade and vertical specialization, which may both govern the long-run relationship between real exchange rates and trade flows. We employ sample information from 13 manufacturing industries across five Asian countries from 2001 to 2015. Rather than country-level aggregate measures, we use disaggregated industry-specific real exchange rates, which provide better measures of relative national prices and may help to uncover different responses that are masked by aggregate data. Fixed-effect estimations reveal that greater price competitiveness, as measured by depreciation in industry-specific effective real exchange rates, increases industry-level trade balances. We find that the elasticity of industry-level trade balances with respect to industry-specific real exchange rates declines as vertical specialization increases. There is also some limited evidence that this elasticity increases as intra-industry trade increases. Taken together, our findings suggest that global supply chains are more important than intra-industry trade in examining the response of trade balances to real exchange rate changes. Importantly, these heterogeneous impacts imply that policies regarding exchange rate management may be of limited potency and will affect different industries in different ways.
