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...

The paper analyzes the production structure and the demand for inputs in three major industrialized countries, the U.S., Japan and Germany. A dynamic factor demand model with two variable inputs (labor and energy)and two quasi-fixed inputs (capital and R&D) is derived directly from an...

In this paper we emphasize the contribution of technical change, broadly defined, towards productivity growth in explaining the relative East Germany-West Germany performance during the post-World War II era. We argue that previous work was excessively focused on physical capital investments...

We examine productivity growth since World War II in the five leading research economies: West Germany, France, the United Kingdom, Japan, and the United States. Available data on the capital-output ratio suggest that these countries grew as they did because of their ability to adopt more...

We explore the response of employment (unemployment) skill differentials to skill-biased shifts in demand touched off by the new and spreading technologies. We find that skill differentials in unemployment follow at least in part the same pattern as skill differentials in wages: They widen...

This essay discusses the effect of technical change on wage inequality. I argue that the behavior of wages and returns to schooling indicates that technical change has been skill-biased during the past sixty years. Furthermore, the recent increase in inequality is most likely due to an...

I analyze an economy in which profit-maximizing firms can undertake both labor- or capital-augmenting technological improvements. In the long run, the economy looks like the standard growth model with purely labor-augmenting technical change, and the share of labor in GDP is constant. Along the...

This paper analyzes the factors contributing to the worldwide long-run rise in obesity and the effects of public interventions on its continued growth. The growth of obesity in a population results from an increase in calorie consumption relative to physical activity. Yet in developed countries,...

This paper surveys the major changes in patent policy and practice that have occurred in the last two decades in the U.S., and reviews the existing analyses by economists that attempt to measure the impacts these changes have had on the processes of technological change. It also reviews the...

This paper uses a new pre-1940 Third World data base documenting real wages and relative factor prices to explore their determinants. There are three possibilities: external price shocks, factor endowment changes, and technological change. As the paper's title suggests, technological change is...
