We compute quality-adjusted price indexes for Personal Digital Assistants (PDAs) for the period 1999-2004, using data on prices and characteristics of 203 models sold by 12 manufacturers. The PDA market is growing in size, it is technologically dynamic with very substantial changes in measured...

This paper studies price and quality differences across international intermediate input suppliers. We develop price measures that account for (i) differences in product characteristics, (ii) unobserved quality differences, and (iii) pure (frictional) price dispersion across suppliers. Using...

Research on intellectual property has focused on formal legally recorded rights that we call deeded, most often measured by granted patents. Meanwhile, other "defacto" IP (mainly purposive secrecy and natural excludability) has become more important because of the increasing closeness of...

In Silicon Valley's computer cluster, skilled employees are reported to move rapidly between competing firms. This job-hopping facilitates the reallocation of resources towards firms with superior innovations, but it also creates human capital externalities that reduce incentives to invest in...

56K modems were introduced under two competing incompatible standards. We show the importance of competition between Internet Service Providers in the adoption process. We show that ISPs were less likely to adopt the technology that more competitors adopted. This result is particularly striking...

Research on the nanoscale has revolutionized areas of science and has begun to have an impact on, and be impacted by, society and economy. We are capturing early traces of these processes in NanoBank, a large scale, multi-year project to provide a public data resource which will link individuals...

In this paper we construct a number of quality-adjusted price indexes for personal computers in the U.S. marketplace over the 1989- 92 time period. We generalize earlier work by incorporating simultaneously the time, age and vintage effects of computer models into a fully saturated...

This paper develops and estimates cost-of-living indexes (e.g., Fisher and Griliches [1995]) for measuring buyer benefits from technical change in the commercial mainframe computer industry in the 1980s. For this purpose we use a micro-econometric model of demand for product characteristics...

An economy benefits from advances in technical frontiers only when new technology comes into general use. This paper measures the diffusion of computing equipment at a time when computing technology underwent dramatic technical improvement. These data shed light on the long lag between advances...

Sparked by concerns about their shrinking market share, 14 leading U.S. semiconductor producers, with the financial assistance of the U.S. government in the form of $100 million in annual subsidies, formed a joint R&D consortium -- Sematech -- in 1987. Using Compustat data on all U.S....
