Trade Liberalization and Welfare Inequality: a Demand-Based Approach

There is strong evidence that different income groups consume di¤erent bundles of goods. This evidence suggests that trade liberalization can a¤ect welfare inequality within a country via changes in the relative prices of goods consumed by di¤erent income groups (the price effect). In this paper, I develop a framework that enables us to explore the role of the price effect in determining welfare inequality. There are two core elements in the model. First, I assume that heterogenous in income consumers share identical but nonhomothetic preferences. Secondly, I consider a monopolistic competition environment that leads to variable markups a¤ected by trade and trade costs. I �nd that trade liberalization does affect the prices of different goods differently and, as a result, can bene�fit some income classes more than others. In particular, I show that the relative welfare of the rich with respect to that of the poor has a hump shape as a function of trade costs

Consumer Preferences in Monopolistic Competition Models

This paper develops a novel approach to modeling references in monopolistic competition models with a continuum of goods. In contrast to the commonly used CES preferences, which do not capture the e¤ects of consumer income and the intensity of competition on equilibrium prices, the present preferences can capture both effects. I show that under an unrestrictive regularity assumption, the equilibrium prices decrease with the total mass of available goods (which represents the intensity of competition in the model) and increase with consumer income. The former implies that the entry of �rms in the market or opening a country to international trade has a pro-competitive effect that decreases equilibrium prices

Affirmative Action: One Size Does Not Fit All

This paper identifies a new reason for giving preferences to the disadvantaged using a model of contests. There are two forces at work: the effort effect working against giving preferences and the selection e¤ect working for them. When education is costly and easy to obtain (as in the U.S.), the selection effect dominates. When education is heavily subsidized and limited in supply (as in India), preferences are welfare reducing. The model also shows that unequal treatment of identical agents can be welfare improving, providing insights into when the counterintuitive policy of rationing educational access to some subgroups is welfare improving
