In this paper, we explore the role of trade in differentiated final goods as well offshoring of tasks for inequality both within and between countries. We emphasize the distinction between managerial and production labor. Production labor is assumed to be a variable input composed of tradable...

This paper provides first firm-level evidence of the links between income inequality and the patterns of trade and export prices. We identify a theoretical mechanism behind these links, which suggests that a more unequal income distribution leads to higher average prices. We test the theory...

This paper studies the market and welfare effects of income heterogeneity in monopolistically competitive product markets in the context of nonhomothetic preferences. In a closed economy, where richer individuals' expenditures are less sensitive to price change compared to poorer ones', a...
