Export Market Dynamics and Plant‐Level Productivity: Impact of Tariff Reductions and Exchange‐Rate Cycles*
利用加拿大制造业三十年数据，研究关税和行业汇率变化如何影响企业进入退出出口市场及生产率增长，发现出口企业生产率增长更快，但加元升值几乎抵消了新出口商的增长优势。
Abstract In this paper, we examine how changes in tariff rates and industry‐specific real exchange rates affect the entry/exit process to export markets and productivity growth. Using the experience of the Canadian manufacturing sector over three decades, we find that firms in export markets enjoy faster productivity growth than non‐participants. The size of the growth advantage depends on whether real exchange rates are increasing or decreasing. The increase in the value of the Canadian dollar during the post‐2000 period almost completely offset the productivity growth advantages enjoyed by new exporters during this period.
