Recent developments on trade and inequality
综述过去十年贸易与不平等文献，讨论贸易对名义收入不平等的影响（企业异质性与流动摩擦）、开放经济中政府的再分配作用，以及贸易通过支出渠道影响实际收入不平等的研究现状。
Abstract This paper surveys developments in the literature on trade and inequality over the past decade. I first discuss the impact of trade on nominal income inequality, with a focus on firm heterogeneity and the role of mobility frictions. Then, I provide an overview of the literature on the redistributional role of government in an open economy. Finally, I assess the current state of studies on how trade affects real income inequality through the expenditure channel.
