Abstract

This study identifies the effect of sectoral composition of trade on inequality in the emerging economies. We separate export and import into four broad sectors such as agriculture; labor-intensive manufacturing; capital-intensive manufacturing and service, and measure revealed comparative advantage (RCA) of each sector. We then identify the effect of growing export; import; and comparative advantage of these sectors on inequality. The study applies dynamic panel data model to a panel dataset of 31 emerging economies over 1994-2014. We take both relative and absolute measures of inequality to solve the debate regarding measurement issues of inequality. The study results suggest that trade in different sectors have differential effect on inequality measured by Gini and ratio of average income of highest and lowest quintiles, but it significantly increases income differences between the two extreme quintiles of income group. Technology has a mixed effect on relative inequality, but it substantially raises absolute income differences between the highest and lowest quintiles.
行业贸易构成对不平等的影响:来自新兴经济体的证据
本研究确定了贸易部门构成对新兴经济体不平等的影响。我们把出口和进口分成四大部门,如农业;劳动密集型的制造业;资本密集型制造业和服务业,以及衡量各部门的显性比较优势(RCA)。然后我们确定了出口增长的影响;进口;以及这些部门在不平等方面的比较优势。本研究采用动态面板数据模型对31个新兴经济体1994-2014年的面板数据集进行分析。我们采用相对和绝对的不平等度量来解决关于不平等度量问题的争论。研究结果表明,不同行业的贸易对基尼系数和最高和最低五分位数平均收入之比衡量的不平等有不同的影响,但它显著增加了收入群体中两个极端五分位数的收入差距。技术对相对不平等的影响是混合的,但它大大增加了最高和最低五分之一之间的绝对收入差距。
