We document that delivery lags and transaction-level economics of scale matter for international trade, leading importers to import infrequently and hold additional inventory. In a model with these frictions calibrated to empirical measures of inventory and trade lumpiness, these frictions have...

We examine the source of the large fall and rebound in US trade in the recent recession. While trade fell and rebounded more than expenditures or production of traded goods, we find that relative to the magnitude of the downturn, these trade fluctuations were in line with those in previous...

We develop a model of households with multiple needs (smoothing shocks, financing investment) and constraints (limited credit, self-control issues) in order to examine the nature of household's financing constraints in a developing country, and the impact of relaxing them. We show that increased...

We develop a quantitative framework to explain the relationship between aggregate/sector-level total factor productivity (TFP) and financial development across countries. Financial frictions distort the allocation of capital and entrepreneurial talent across production units, adversely affecting...

We provide a simple quantitative general equilibrium model of occupational choice with credit market frictions to analyze the aggregate and distributional effects of asset transfer programs. Asset transfer programs have a positive but transient effect on aggregate productivity, and a negative...

This paper analyzes the role of specialized high-skilled labor in the disproportionate growth of the service sector. Empirically, the importance of skill-intensive services has risen during a period of increasing relative wages and quantities of high-skilled labor. We develop a theory in which...

We use producer-level data to evaluate the role of financial frictions in determining total factor productivity (TFP). We study a model of establishment dynamics in which financial frictions reduce TFP through two channels. First, finance frictions distort entry and technology adoption...
