We introduce unemployment and endogenous selection of workers into different skill-classes in a trade model with two sectors and heterogeneous firms. This allows us to study the distributional consequences and the skill-specific unemployment effects of trade liberalization. We show that the...

To explain the rise in the college wage premium in developed economies in the past decades, the present paper examines the effects of technological progress on workers effort incentives, which determine the effective labor supply. Five effort incentive effects of technological progress are...

This paper develops a dynamic general equilibrium model to highlight the role of human capital accumulation of agents differentiated by skill type in the joint determination of social mobility and the skill premium. We first show that our model captures the empirical co-movement of the skill...

We investigate the theoretical relationship between wage concentration and international market integration. Access to imported varieties lowers the cost of intermediate inputs (“machines”) used to carry out production tasks, causing workers with different comparative abilities to be sorted...

This paper analyzes trade in an asymmetric 2×2×2 world, where the two countries, labelled America and Europe, differ in their attitudes towards wage inequality. In both America and Europe, fair wage considerations compress differentials between the wages for skilled and unskilled workers,...

In many developing economies rate of unemployment is increasing with skill accumulation and thereby leading to underemployment. Our paper offers to look at skill formation as a demand side problem not as a traditional supply side problem and also how skill formation or education affects...

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...

To examine how human capital accumulation influences both economic growth and income inequality, we carefully endogenize the demand and supply of skills. We explicitly introduce the costs and externalities in education, and examine how both relate to learning-by-doing and R&D intensity. In...

We construct a two sector general equilibrium model in which one sector produces a homogeneous good and the other sector produces a vertically differentiated good. We demonstrate that uniform (across sectors) and (Hicks) neutral technological change can cause an increase in the skill premium.
