摘要
This paper examines the influence of large real exchange rate movements on firm turnover and production scale, and the contribution of these decisions to productivity growth. Our theoretical model predicts that home currency appreciations cause firm closure and reduce surviving firms' exports while boosting domestic sales. The net effect on sales and productivity therefore depends on changes in domestic sales and exports. Taiwanese firm-level data are used to test these predictions. The results show that real currency appreciations lead to scale expansion of surviving firms which in turn raises productivity. Our findings suggest the existence of a significant scale effect. © 2008 The Canadian Economics Association.
