Previous studies that investigated the impact of exchange rate volatility on Korean trade flows assumed that the effects are symmetric. When we change this assumption and investigate the asymmetric effects of the real won-dollar volatility on 61 U.S. exporting industries to Korea and on 49 U.S. importing industries from Korea, we discover relatively more significant and asymmetric effects. Indeed, we find short-run asymmetric effects in 37 U.S. exporting industries that last into significant long-run asymmetric effects in 29 of them. We also find short-run asymmetric effects on imports of 24 industries that last into significant long-run asymmetric effects in 33 out of 49 industries.

论汇率波动对贸易流动的不对称影响：来自韩美商品贸易的证据

先前研究汇率波动对韩国贸易流动的影响的研究假设影响是对称的。当我们改变这一假设并研究实际韩元波动对美国对韩出口的 61 个行业和美国从韩国进口的 49 个行业的不对称影响时，我们发现相对更显着和不对称的影响。事实上，我们发现 37 个美国出口行业的短期不对称效应持续到其中 29 个行业的显着长期不对称效应。我们还发现对 24 个行业的进口的短期不对称影响持续到 49 个行业中的 33 个行业的显着长期不对称影响。
