Exchange rates have been changed unusually large these days. From 2011 to 2016, the Euro and the Japanese Yen have depreciated against the US Dollar by more than 25 percent. According to a theory, since competitively valued exchange rate helps to boost export growth, we should have observed a sub-stantial increase in export in the EU and Japan. However, the effectiveness of the exchange rates on exports appears to be weak across countries. This anomaly is one of the central puzzles in international macroeconomics: why large movements in the exchange rate have modest effects on the aggregate variables such as import prices, consumer prices, and quantity of exports.
In this paper, we examines the role of global production linkages on ex-change rate elasticities by using Korean firm-level data. At firm-level, foreign-owned firms or firms with foreign subsidiaries participated in the Global Value Chains (GVC) play an important role in weakening the effect of ex-change rate movements on firm exports. The empirical results show that the exchange rate elasticity of total export is about -0.64, which implies that 10% appreciation of Korean Won would make a drop in total export by 6.4%. However, the exchange rate elasticities of firms are not the homogeneous across firms. We find that the exchange rate elasticities of firm exports are significant and negative for domestic-owned firms and firms without foreign subsidiary whereas those are insignificant for foreign-owned firms and firms with foreign subsidiaries.
After controlling exports to foreign affiliates, we still find that the estimated exchange rate elasticities of exports are statistically insignificant, but become negative and relatively larger for firms with global production linkages. More-over, firms with higher GVC integration measure or more imported inter-mediate inputs have the significantly lower exchange rate elasticities of firm exports. It suggests that developments of global production linkages via firm ownership, within-industry or within-firm in the last decade play an essential role in alleviating the effect of exchange rate movements on the firm exports.
