This paper investigates the significance of Research and Development (R&D) spillovers through intra- and international trade in intermediate goods for productivity growth in a panel of OECD industries during 1973-1994. In the model, four different sources of R&D are identified: R&D conducted in...

This paper investigates whether the Democratic Party has any significant effects on unions. Employing Regression Discontinuity (RD) approach on gubernatorial elections in U.S. states over the last three decades, we investigate causal effects of Democratic governors on unionization of workers,...

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...

In this paper, I analyze the time paths of the efficiencies of skilled and unskilled labor in a production framework where skilled and unskilled labor are imperfect substitutes. Their implications for economic growth and wage inequality in the US between 1950 and 2005 present two main findings....

This paper develops a fully endogenous, variety-expansion growth model with firm-specific quality heterogeneity, limit pricing, and an endogenous distribution of markups. Firms with high-quality products engage in exporting, firms with intermediate-quality products serve the domestic market, and...

This paper investigates the impact of unskilled workers' earnings on crime. Following the literature on wage inequality and skill-biased technological change, we employ CPS data to create state-year as well as state-year-and (broad) industry specific measures of skill-biased technological...

I investigate the long-run implications of trade and technology diffusion through trade, when firms are heterogeneous and trade is costly. This paper integrates firm heterogeneity and trade into a product innovation growth model from endogenous growth theory. I find that although exposure to...

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...
