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 investigates the impact of mothers' earnings on birth weight and gestational age of infants. It also analyzes the impact of earnings on mothers' consumption of prenatal medical care, and their propensity to smoke and drink during pregnancy. The paper uses census-division- and...

This paper develops a fully-endogenous, variety-expansion growth model with firm-specific 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...

China's growth record since the start of its economic reforms in 1978 has been extraordinary. Yet, this impressive performance has been associated with an increasing regional income disparity. We use a recently developed nonparametric approach to analyze the variation in labor productivity...

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...

The Great Recession, which was preceded by the Financial Crisis, resulted in higher unemployment and income inequality. We propose a simple model where firms producing varieties face labor-market frictions and credit constraints. In the model, tighter credit leads to lower output, a lower number...

We propose a multi-country model with occupational choice, heterogeneous firms, unemployment, and revenue-generating tariffs to study the aggregate and distributional consequences of tariff wars in a unified framework. Motivated by the 2018 global tariff war, we calibrate the model to fit a...

Exploiting variation in exposure to Chinese import growth across U.S. local markets, I investigate the effects of import competition on self-employment between 1990 and 2014. I find Chinese import competition had negative effects on self-employment during the 1990s. However, the negative effects...
