The wage impact of immigration depends crucially on the elasticity of substitution between similarly skilled immigrants and natives and the elasticity of substitution between high school dropouts and graduates. This paper revisits the estimation of these elasticities. The U.S. data indicate that...

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...

We investigate the regulation of labor markets through employment laws, collective bargaining laws, and social security laws in 85 countries. We find that richer countries regulate labor less than poorer countries do, although they have more generous social security systems. The political power...

Current concern with relationships among particular technologies, capital, and the wage structure motivates this study of the origins of technology-skill complementarity in manufacturing. We offer evidence of the existence of technology-skill and capital-skill (relative) complementarities from...

Neglected, but significant, the long-run consequence of the minimum wage - which was made national policy in the United States in 1938 - is its stimulation of capital deepening. This took two forms. First, the engineered shortage of low-skill, low-paying jobs induced teenagers to invest in...

Wage evidence suggests that immigrant workers are imperfectly substitutable for native-born workers with similar education and experience. Using U.S. Censuses and recent American Community Survey data, I ask to what extent differences in language skills drive this. I find they are important. I...

This paper develops a new theory of international economics by introducing Heckscher-Ohlin features of intra-temporal trade into an intertemporal trade approach of current account. To do so, we consider a dynamic general equilibrium model with tradable sectors of different factor intensities,...

We estimate an aggregate production function with constant elasticity of substitution between energy and a capital/labor composite using U.S. data. The implied measure of energy-saving technical change appears to respond strongly to the oil-price shocks in the 1970s and has a negative medium-run...

Academics, the media, and policymakers have all raised concerns about the implications of human workers being replaced by machines or software. Few have discussed the implications of the reverse: firms' ability to replace capital with workers. We show that this flexibility can help new firms...

A central determinant of the political economy of capital-labor relations is the appropriability of specific quasi-rents. quot; This paper is concerned with the general-equilibrium interaction of appropriability and characteristics of technology namely, the embodiment of technology in capital...
