We analyze changes in the gender structure at the top of the earnings distribution in the United States over the last 30 years using a 10% sample of individual earnings histories from the Social Security Administration. Despite making large inroads, females still constitute a small proportion of...

Do robots raise or lower economic well-being? On the one hand, they raise output and bring more goods and services into reach. On the other hand, they eliminate jobs, shift investments away from machines that complement labor, lower wages, and immiserize workers who cannot compete. The net...

What contributes to the growing income inequality across U.S. households? We develop an information- based general equilibrium model that links capital income derived from financial assets to a level of investor sophistication. Our model implies income inequality between sophisticated and...

We identify a key role of factor supply, driven by demographic changes, in shaping several empirical regularities that are a focus of active research in macro and labor economics. In particular, demographic changes alone can account for the large movements of the return to experience over the...

Projected demographic changes in industrialized and developing countries vary in extent and timing but will reduce the share of the population in working age everywhere. Conventional wisdom suggests that this will increase capital intensity with falling rates of return to capital and increasing...

We develop a framework to estimate the aggregate capital-labor elasticity of substitution by aggregating the actions of individual plants, and use it to assess the decline in labor's share of income in the US manufacturing sector. The aggregate elasticity reflects substitution within plants and...

The labor share is typically measured as compensation to labor relative to gross value added ("gross labor share"), in part because gross value added is more directly measured than net value added. Labor compensation relative to net value added ("net labor share") may be more important in some...

Value and momentum strategies earn persistently large return premia yet are negatively correlated. Why? We show that a quantitatively large fraction of the negative correlation is explained by strong opposite signed exposure of value and momentum portfolios to a single aggregate risk factor...

This paper explores the relationship between openness to trade and to immigration on income per person. To address endogeneity concerns we extend the instrumental-variables strategy first used by Frankel and Romer (1999). We show that distance (geographical and cultural) can be used to build a...

This paper revisits the important ideas proposed by Atkinson and Stiglitz's seminal 1969 paper on technological change. After linking these ideas to the induced innovation literature of the 1960s and the more recent directed technological change literature, it explains how these three...
