Changes in National Technological Competitiveness: 1990, 1993, 1996 and 1999

Georgia Tech’s Technology Policy and Assessment Center, with support from the US National Science Foundation, has been generating High-Tech Indicators (HTI)—measures of national technology-based export competitiveness since 1987. This paper reports the HTI results for 33 nations in 1999 in comparison with those of 1990, 1993 and 1996. HTI includes four ‘input indicators’ and a key ‘output indic...

The Technological Impact of Diffusion in Nanopores

The impact of nanopore diffusion on the performance of adsorption separation processes is reviewed. Zeolite membrane processes and kinetically selective cyclic adsorption processes depend for their selectivity on differences in intracrystalline diffusion rates so these processes are designed to operate under conditions of intracrystalline diffusion control. In contrast, the performance of equil...

Impact of Technological Change and Productivity on the Coal Market

The strong pace of improvement in coal industry labor productivity has been a major reason for the decline in coal minemouth prices that has taken place since 1979. The Annual Energy Outlook 2000 (AEO2000) forecast projects that labor productivity on a national basis will improve on average at a rate of 2.3 percent per year between 1998 and 2020, declining from an annual rate of 6.1 percent ach...

1 The Impact of Technological Change on Work and Wages

I. The Issues How technology affects work and pay has been an important topic in the study of labor markets and wage distribution. In this review article, we provide an overview of recent research in two particular areas: how technological change has affected wage and employment structures nationally, and how technological change has affected work at the establishment or plant level. With a few...
