Revisiting Capital-Skill Complementarity, Inequality, and Labor Share
This paper revisits capital-skill complementarity and inequality, as in Krusell, Ohanian, Rios-Rull and Violante (KORV, 2000). Using their methodology, we study how well the KORV model accounts for more recent data, including the large changes in the labor's share of income that were not present in KORV. We study both labor share of gross income (as in KORV), and income net of depreciation. We also use nonfarm business sector output as an alternative measure of production to real GDP. We find strong evidence for continued capital-skill complementarity in the most recent data, and we also find ...

The Evolution of Comparative Advantage: Measurement and Implications
We estimate productivities at the sector level for 72 countries and 5 decades, and examine how they evolve over time in both developed and developing countries. In both country groups, comparative advantage has become weaker: productivity grew systematically faster in sectors that were initially at greater comparative disadvantage. These changes have had a significant impact on trade volumes and patterns, and a non-negligible welfare impact. In the counterfactual scenario in which each country's comparative advantage remained the same as in the 1960s, and technology in all sectors grew at the ...

Capital-Task Complementarity and the Decline of the U.S. Labor Share of Income
This paper provides evidence that shifts in the occupational composition of the U.S. workforce are the most important factor explaining the trend decline in the labor share over the past four decades. Estimates suggest that while there is unitary elasticity between equipment capital and non-routine tasks, equipment capital and routine tasks are highly substitutable. Through the lenses of a general equilibrium model with occupational choice and the estimated production technology, I document that the fall in relative price of equipment capital alone can explain 72 percent of the observed ...

Technological innovation in mortgage underwriting and the growth in credit, 1985–2015
The application of information technology to finance, or ?fintech,? is expected to revolutionize many aspects of borrowing and lending in the future, but technology has been reshaping consumer and mortgage lending for many years. During the 1990s, computerization allowed mortgage lenders to reduce loan-processing times and largely replace human-based assessments of credit risk with default predictions generated by sophisticated empirical models. Debt-to-income ratios at origination add little to the predictive power of these models, so the new automated underwriting systems allowed higher ...

Indivisibilities in Distribution
This paper develops and estimates a model of indivisibilities in shipping and economies of scale in consolidation. It uses highly detailed data on imports where it is possible to observe the contents of individual containers. In the model, ?rms are able to adapt to indivisibility constraints by using consolidation strategies and by making adjustments to shipment size. The ?rm determines the optimal number of domestic ports to use, taking into account that adding more ports lowers inland freight cost, at the expense of a higher indivisibility cost. The estimated model is able to roughly ...

The Long-Term Rise of Labor Market Detachment: Evidence from Local Labor Markets
We develop a measure of chronic joblessness among prime-age men and women in the United States—termed the detachment rate— that identifies those who have been out of the labor force for more than a year. We show that the detachment rate more than doubled for men since the early 1980s and rose by a quarter for women since 2000, though it is consistently considerably higher for women than men. We then explore the economic geography of labor market detachment to help explain its rise. Results show that the detachment rate increased more in places with weak local economies, particularly those ...

The Nature of Technological Change 1960-2016
We present a unified technological explanation of both the movement of workers across jobs using different skills and the changes in skill use within jobs. An envelope-theorem approach allows us to estimate relative skill-productivity growth from worker mobility using OLS while making minimal assumptions on each occupation's production function. Using six decades of data, we conclude that routine-cognitive- and finger-dexterity-skill productivity grew rapidly and abstract- and social-skill productivity grew slowly - a form of "skill bias." These effects, along with our estimated relationships ...

The City Paradox: Skilled Services and Remote Work
Large cities in the US are the most expensive places to live. Paradoxically, this cost is paid disproportionately by workers who could work remotely, and live anywhere. The greater potential for remote work in large cities is mostly accounted for by their specialization in skill- and information-intensive service industries. We highlight that this specialization makes these cities vulnerable to remote work shocks. When high-skill workers begin to work from home or leave the city altogether, they withdraw spending from local consumer service industries that rely heavily on their demand. As a ...
