Trade Reform Dynamics and Technical Efficiency: The Peruvian Experience
研究了1990年秘鲁贸易改革对工厂层面技术效率的影响，发现保护程度与效率水平呈反向关系，对关注贸易政策与产业效率的学者有参考价值。
Markets around the world are becoming more competitive because of changing operating and regulatory environments. One such change—the loosening of trade restrictions— is a macroeconomic policy shift that should have a microeconomic impact on industrial efficiency. Specifically, competitive pressure should discipline or eliminate inefficient producers. This article explores whether or not there is such a dynamic link. It uses a previously unexploited data set to gauge the impact of the 1990 Peruvian reform on plant-level technical efficiency. The results support the argument that the degree of protection and the level of efficiency are inversely related.
