Over the last twenty years the wage-education relationships in the US and Germany have evolved very differently, while the education composition of employment has evolved in a surprisingly parallel fashion. In this paper, we propose and test an explanation to these conflicting patterns. The...

Wage inequality in the United States has increased, and many suspect that the main causes are changes in technology, international competition, and factor supplies. Our empirical model estimates the general equilibrium relationship between wages and technology, prices, and factor supplies. The...

We document that between 50% and 70% of changes in the US wage structure over the last four decades are accounted for by the relative wage declines of worker groups specialized in routine tasks in industries experiencing rapid automation. We develop a conceptual framework where tasks across a...

The U.S. wage structure evolved across the last century: narrowing from 1910 to 1950, fairly stable in the 1950s and 1960s, widening rapidly during the 1980s, and "polarizing" since the late 1980s. We document the spectacular rise of U.S. wage inequality after 1980 and place recent changes into...

In this paper we present an analytically tractable overlapping generations model of human capital accumulation, and study its implications for the evolution of the U.S. wage distribution from 1970 to 2000. The key feature of the model, and the only source of heterogeneity, is that individuals...

In this paper, we construct a parsimonious overlapping-generations model of human capital accumulation and study its quantitative implications for the evolution of the U.S. wage distribution from 1970 to 2000. A key feature of the model is that individuals differ in their ability to accumulate...

This paper examines the determinants of changes in the US wage structure over the period 1976-2000, with the objective of evaluating whether these changes are best described as the result of ongoing skill-biased technological change, or alternatively, as the outcome of an adjustment process...

Wages for more- and less-educated workers have followed strikingly different paths in the U.S. and Canada. During the 1980's and 1990's, the ratio of earnings of university graduates to high school graduates increased sharply in the U.S. but fell slightly in Canada. Katz and Murphy (1992) found...

We develop an empirical framework to assess the importance of trade and technical change on the wages of production and nonproduction workers. Trade is measured by the foreign outsourcing of intermediate inputs, while technical change is measured by the shift towards high-technology capital such...

This paper investigates three hypotheses to account for the observed shifts in U.S. relative wages of less educated compared to more educated workers between 1967 and 1992: increased import competition, changes in the relative supplies of labor of different education levels and changes in...
