Theoretical models of endogenous growth identify capital accumulation and returns as a potential stimulus to economic growth. Existing empirical studies, however, are based on a limited notion of these returns, which follows from the simple production function framework used for estimation. The...

We use transaction-level data to study changes in the concentration of US imports. Concentration has fallen in the typical industry, while it is stable by industry and origin country. The fall in concentration is driven by the extensive margin: the number of exporting firms has grown, and the...

A typical (roughly) two-digit industry in the United States appears to have constant or slightly decreasing returns to scale. Three puzzles emerge, however. First, estimates often rise at higher levels of aggregation. Second, apparent decreasing returns contradicts evidence of only small...

We provide industry-level estimates of the elasticity of substitution (σ) between capital and labor in the US economy. We also estimate rates of factor-augmentation. Aggregate estimates are produced using the same data. Our empirical model comes from the first-order conditions associated with a...

I propose a new decomposition of aggregate total factor productivity. I model productivity as an index of unmeasured … factors of production, and decompose the conditional factor demand for this index. With this model of productivity, changes in … the price of labor or capital cause substitution to or from productivity. I study whether such changes explain the …
