What are the welfare implications of trade shocks? We provide a sufficient statistic that measures changes in welfare, to a first-order approximation, taking into account adjustment in labor supply, in frictional unemployment, and in the sectors to which workers apply while allowing for...

This paper explores how different margins of market share are related to markups. Using merged microdata on producers and consumers, we document that a firm's market share is mainly related to its number of customers, while its price-cost markup is associated only with its average sales per...

In this paper we present and solve a three-stage game of entry, location, and pricing in a spatial price discrimination framework with arbitrarily many heterogeneous firms. We provide a unique characterization of all equilibria without imposing restrictions on the distribution of marginal costs

What is the impact of the minimum wage on the college wage premium? I show that job-ladder models imply that the effect should be small on impact---raising only the wages of workers bound by the minimum wage---and grow over time as workers slowly move up the job ladder. Guided by my theory, I...

I generalize the canonical model--in which relative supply and demand for worker skills shape the skill premium--incorporating monopsony power, minimum wages, and unemployment. I estimate the extended canonical model using national data and, separately, state-level data. I show that...

What are the unequal effects of changes in consumer prices on the cost of living? In the context of changes in import prices, most analyses focus on variation across households in initial expenditure shares on imported goods. However, the unequal welfare effects of non-marginal foreign price...

The 1940s witnessed substantial reductions in the Black-white earnings gap. We study the role that domestic WWII defense production played in reducing this gap. Exploiting variation across labor markets in the allocation of war contracts to private firms, we find that war production contracts...

We construct a model of international trade and multinational production (MP) to examine the impact of globalization on the skill premium in skill-abundant and skill-scarce countries. The key mechanisms in our framework arise from the interaction between three elements: cross-country differences...
