In the past two decades China leaped from bit player in global science and engineering (S&E) to become the world's largest source of S&E graduates and the second largest spender on R&D and second largest producer of scientific papers. As a latecomer to modern science and engineering, China...

The cross-national intragenerational income mobility literature assumes within-country mobility is invariant over the period measured. We argue that a great social transformation--German reunification-- abruptly and permanently altered economic mobility. Using standard measures of mobility (with...

There are several ways to measure fatness and obesity, each with its own strengths and weaknesses. The primary measure for tracking the prevalence of obesity has historically been body mass index (BMI). This paper compares long-run trends in the prevalence of obesity when obesity is defined...

This paper examines evidence regarding the impact of the changed labor market on the higher educational system. Four basic propositions can be drawn from the paper's findings. Firstly, the labor market for the highly educated underwent a downturn in the 1970s, reducing the relative earnings of...

This paper develops four propositions that show that changes in the global job market for science and engineering (S&E) workers are eroding US dominance in S&E, which diminishes comparative advantage in high tech production and creates problems for American industry and workers: (1) The U.S....

This study presents new estimates of collective bargaining coverage and union membership for detailed U.S. industries. It compares the new coverage and membership figures with each other and with figures derived by researchers for the early 1960's and analyzes the divergences. This analysis...

During the 1970s and 1980s immigration, trade, and foreign investment became increasingly important in the U.S. labor market. The number of legal and illegal immigrants to the country increased, altering the size and composition of the work force and substantially raising the immigrant share of...
