This paper analyzes the sources of U.S. productivity growth in recent years using both aggregate and industry-level data. We confirm the central role for information technology (IT) in the productivity revival during 1995-2000 and show that IT played a significant, though smaller, role after...

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...

The performance of the U.S. economy over the past several years has been remarkable, including a rebound in labor productivity growth after nearly a quarter century of sluggish gains. To assess the role of information technology in the recent rebound, this paper re-examines the growth...

This paper examines three questions motivated by previous research on semiconductors and productivity growth: Why did semiconductor prices fall so rapidly in the second half of the 1990s, why has the rate of price decline slowed since 2001, and to what extent are these price swings associated...

Productivity growth in the U.S. economy jumped during the second half of the 1990s, a resurgence that many analysts linked to information technology (IT). However, shortly after this consensus emerged, demand for IT products fell sharply, leading to a lively debate about the connection between...

The performance of the U.S. economy over the past several years has been remarkable, including a rebound in labor productivity growth after nearly a quarter century of sluggish gains. To assess the role of information technology in the recent rebound, this paper re-examines the growth...

This paper examines the prices for communications equipment, an important component of information technology. Unlike prices for computers which officially fall sharply every year, the official prices for communications equipment have barely budged over the past decade. This paper combines...

Given the slow growth of labor productivity in recent years, some have argued that the boost from information technology may have run its course Our analysis points to a less pessimistic conclusion While projections of economic developments are always difficult, our judgment is that "No, the...

The recent slowdown in the rate of decline for semiconductor prices suggested by the PPI is puzzling in light of evidence that the performance of MPUs has continued to improve at a rapid pace. The authors argue that hedonic indexes provide a more accurate measure of price changes.
