The role of semiconductor inputs in IT hardware price decline: computers vs. communications
Sharp declines in semiconductor prices are largely responsible for observed declines in computer prices. Although communications equipment also has a large semiconductor content, communications equipment prices do not fall nearly as fast as computer prices. This paper partly resolves the puzzle-first noted by Flamm(1989)-by demonstrating that prices for chips used in communications equipment do not fall nearly as fast as prices for those chips used in computers, and those differences are large enough to potentially explain all of the output price differences.
Labor supply and personal computer adoption.
The positive correlations found between computer use and human capital are often interpreted as evidence that the adoption of computers have raised the relative demand for skilled labor, the widely touted skill-biased technological change hypothesis. However, several models argue the skill- intensity of technology is endogenously determined by the relative supply of skilled labor. The authors use instruments for the supply of human capital coupled with a rich dataset on computer usage by businesses to show that the supply of human capital is an important determinant of the adoption of ...
Where's the productivity growth (from the information technology revolution)?
Information technology has advanced rapidly in the last two or three decades, and an equivalent rapid gain in economy-wide productivity has been anticipated. Productivity statistics, however, do not support this expectation. Although productivity growth has risen since the slowdown witnessed in the 1970s, it can hardly be described as phenomenal. Donald S. Allen discusses some of the current explanations for this apparent disparity and suggests that, as the workforce catches up to the technology level and exploits its full potential, productivity growth will increase.
Have computers made us more productive? A puzzle
You say you want an information revolution? Well, it came and changed the world. So where's the explosion in productivity?
Explaining the investment boom of the 1990s
Real equipment investment in the United States has boomed in recent years, led by soaring investment in computers. We find that traditional aggregate econometric models completely fail to capture the magnitude of this recent growth--mainly because these models neglect to address two features that are crucial (and unique) to the current investment boom. First, the pace at which firms replace depreciated capital has increased. Second, investment has been more sensitive to the cost of capital. We document that these two features stem from the special behavior of investment in computers and ...
Firm strategies in the personal computer market: are established brands better off?
The personal computer market underwent significant structural changes throughout the late 1970s and 1980s. While some manufacturers of personal computers managed to remain in the market for a number of years, many others left after a short time. Besides the more visible movement of firms in and out of the industry, each firm also made underlying decisions regarding which models to offer. ; This article analyzes model selection strategies adopted by personal computer (PC) companies from 1976 to 1988, focusing on differences between established and new firms. While new firms were more likely ...
Do differences in countries' capital composition matter?
This Economic Letter explores three questions that arise in light of striking differences in the composition of capital equipment among countries.
Home computers and educational outcomes: evidence from the NLSY97 and CPS
Although computers are universal in the classroom, nearly twenty million children in the United States do not have computers in their homes. Surprisingly, only a few previous studies explore the role of home computers in the educational process. Home computers might be very useful for completing school assignments, but they might also represent a distraction for teenagers. We use several identification strategies and panel data from the two main U.S. datasets that include recent information on computer ownership among children--the 2000-2003 CPS Computer and Internet Use Supplements (CIUS) ...
