Do immigrants have better labor-market outcomes under Democratic governors? By exploiting variations associated with close elections in a regression discontinuity (RD) design applied on gubernatorial elections in 50 states over the last two decades, we find that immigrants are more likely to be...

This paper investigates the impact of schools banning mobile phones on student test scores. By surveying schools in four English cities regarding their mobile phone policies and combining it with administrative data, we find that student performance in high stakes exams significantly increases...

This study proposes a simple theory of trade with endogenous firm productivity, occupational choice, and income inequality. Individuals with different managerial talent choose to become self-employed entrepreneurs or workers. Entrepreneurs enhance firm productivity by investing in managerial...

We propose a simple theory of personal income distribution, equilibrium unemployment, and interindustry trade, in which product markets are perfectly competitive and labor markets exhibit search related frictions. Individuals, based on their managerial talent, choose to become self-employed...

This paper develops a two-country, two-sector model of trade where the only difference between two countries is the cost of human capital formation. It is shown that this difference completely shapes the pattern of trade. Trade, in turn, affects the distribution of human capital both at...

This paper develops a monopolistic competition model with heterogeneous firms to study the interaction between technology adoption and trade in a world of two countries facing different technology adoption costs. It shows that a reduction in the technology adoption cost in one country increases...

This paper develops a fully-endogenous, variety-expansion growth model with firm- specifc quality heterogeneity, limit pricing, and an endogenous distribution of markups. Trade induces only firms with high-quality products to export, whereas firms with low- quality products serve only the...

This paper develops a trade model with firm-specifc quality heterogeneity, limit pricing, and an endogenous distribution of markups. Exposure to trade induces only the firms producing high-quality (high-price) products to enter the export markets, whereas firms producing low-quality (low-price)...

This paper considers a world of two symmetric countries with two factors and two sectors. Outputs of the two sectors are imperfect substitutes and sectors differ in relative factor inten- sity. Each sector contains a continuum of heterogenous firms that produce differentiated goods within their...
