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 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 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...

Starting in the late 1970s, the Indian authorities implemented a series of reforms aimed at exposing the economy to greater competition and at liberalizing key aspects of economic activity. This paper investigates productivity trends in India's (registered) manufacturing sectors during the 1980s...

This paper develops a trade model with firm-specific quality heterogeneity in markets where firms face the threat of imitation and engage in limit-pricing strategies. Firms producing high-quality (high-price) products export, whereas firms producing lower-quality (lower-price) products serve the...

The empirical relationship between trade protection and economic growth is surprisingly fragile, as shown in a number of other papers. After demonstrating this empirical sensitivity, we address one possible explanation for these findings: that the relationship is nonlinear. Following the...

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...

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....
