We describe a model of trade with input based product differentiation and non-proportional trade costs that is capable of predicting a positive correlation between firms' export intensity, the price of their exports, and the wages they pay to their workers. These correlations arise in the model...

This paper studies the relationship between changes in occupational employment, occupational wages, and rising overall wage inequality. Using long-running administrative panel data with detailed occupation codes, we first document that in all occupations, entrants and leavers earn lower wages...

The canonical supply-demand model of the wage returns to skill has been extremely influential; however, it has faced several important challenges. Several studies show that the standard approach sometimes produces theoretically wrong-signed elasticities of substitution, yields counterintuitive...

The skill premium has increased significantly in the United States in the last five decades. During the same period, individual wage risk has also increased. This paper proposes a mechanism through which a rise in wage risk increases the skill premium. Intuitively, a rise in uninsured wage risk...

With the ensuing immigration reform in the US, the paper shows that targeted skilled immigration into the R&D sector that helps low-skilled labor is conducive for controlling inequality and raising wage. Skilled talent-led innovation could have spillover benefits for the unskilled sector while...

We study marital sorting on academic qualifications and latent ability in an equilibrium marriage market model using the 1972 UK Raising of the School-Leaving Age (RoSLA) legislation as a natural experiment that induced a sudden, large shift in the distribution of academic qualifications in...

We analyze the welfare effects of trade and migration, focusing on two-sided horizontal heterogeneity among workers and firms. We prove the existence of a unique symmetric equilibrium in a two stage game of firm entry (including choice of skill-types) and pricing, involving monopsony power on...

This paper examines how skill-biased growth can generate economic fragmentation (income dis-parities) that give rise to social fragmentation (the adoption of increasingly incompatible social identities and values), which generate political fragmentation (the adoption of increasingly incompatible...

This paper studies how linear tax and education policy should optimally respond to skill-biased technical change (SBTC). SBTC affects optimal taxes and subsidies by changing i) direct distributional benefits, ii) indirect redistributional effects due to wage-(de)compression, and iii) education...

Trade shocks in export markets may affect the employment composition and the organization of exporting firms. In particular, the imposition of new technological standards in destination markets may force exporters to adjust the firm's organization to comply and cope with the additional...
