In this paper we examine the importance of local spillovers such as network externalities and learning from others in the diffusion of home computers using data on 110,000 U.S. households in 1997. Controlling for many individual characteristics, we find that people are more likely to buy their...

Results of hedonic price regressions for personal computer operating systems and productivity suites advertised in PC World magazine by retail vendors during the time period 1984 to 2000 are reported. Among the quality attribute variables we use are new measures capturing the presence of network...

Improvements in the software that provides hardware management, user interface and platform functions have played a central role in the growth and transformation of the personal computer (PC) industry. Several forces shape the design of these 'operating system' products and propel their...

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...

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 provides new estimates of depreciation rates for personal computers using an extensive database of prices of used PCs. Our results show that PCs lose roughly half their remaining value, on average, with each additional year of use. We decompose that decline into age-related...

Using a unique and comprehensive data source, we measure price changes for Microsoft's desktop personal computer software products during the time period July 1993 through June 2001. This paper contributes to a relatively small literature on price measurement of pre-packaged software by...

In this paper we focus on alternative procedures for calculating and interpreting quality-adjusted price indexes for microcomputers, based on a variety of estimated hedonic price equations. Our data set comprises an unbalanced panel for 1265 model observations from 1982 to 1988, and includes...

Personal information management systems (PIMS) aka personal data stores (PDSs) represent an emerging class of technology that seeks to empower individuals regarding their data. Presented as an alternative to current ‘centralised’ data processing approaches, whereby user data is (rather...

Researchers and practitioners across many disciplines have recently adopted computational notebooks to develop, document, and share their scientific workflows - and the GIS community is no exception. This chapter introduces computational notebooks in the geographical context. It begins by...

This paper evaluates the sources of transitory market power in the market for personal computers (PCs) during the late 1980's. Our analysis is motivated by the coexistence of low entry barriers into the PC industry and high rates of innovative investment by a small number of PC manufacturers. We...

The value of installed computers falls rapidly and therefore computers have a very high user cost. The paper provides a complete account of the non-financial user cost of personal computers -- decomposing it into replacement cost change, obsolescence, instantaneous depreciation, and age-related...

To identify the determinants of cross-country disparities in personal computer and Internet penetration, we examine a panel of 161 countries over the 1999-2001 period. Our candidate variables include economic variables (income per capita, years of schooling, illiteracy, trade openness),...

There is no clear theoretical prediction regarding whether home computers are an important input in the educational production function. To investigate the hypothesis that access to a home computer affects educational outcomes, we conduct the first-ever field experiment involving the provision...

When workers adopt technology at the point where the costs equal the increased productivity, output per worker increases immediately, while the productivity benefits increase only gradually if the costs continue to fall. As a result, workers in computer-adopting labor market groups experience an...

This paper offers a model to explain how computer technology has changed the labor market. It demonstrates that wage differentials between computer users and non-users are consistent with the fact that computers are first introduced in high-wage jobs because of cost efficiency. Furthermore,...

The large increase in computer use has raised the question whether people have to be taught computer skills before entering the labour market. Using data from the 1997 Skills Survey of the Employed British Workforce, we argue that neither the increase in computer use nor the fact that...

Using data from the 1997 Skills Survey of the Employed British Workforce, we examine the returns to computer skills in Britain. Many researchers, using information on computer use, have concluded that wage differentials between computer users and non-users might, among others, be due to...

In this paper, the role of the computer at the workplace will be examined in determining the wage structure in Germany. Following Krueger (1993) and using the German Socio-Economic Panel (GSOEP), cross-sectional wage regression results from 1997 and panel results from 1984-1997 are presented. It...

Using 1985-1999 data from the German Socio-Economic Panel Study (GSOEP) to analyze wages confirms the hypothesis that existing computer wage premiums are determined by individual ability or other unobserved individual characteristics rather than by productivity effects. While a rather large...
