We study whether aggregation residuals in U.S. private investment in information technology (IT) exhibit a predictable pattern that is consistent with Hicks' composite-good theorem and that may be used for forecasting. To determine whether one can extract such a pattern, we apply the...

While information technologies (IT) are credited with the recent acceleration in productivity in the United States, many other industrial countries have not experienced a pickup in productivity growth. To explain this productivity divergence, we use panel data from 1992 to 1999 for 13 industrial...

This study examines the adoption of hospital information systems (HIS), specifically focusing on the connection between the financing of health care and the adoption of these new technologies. Using a recently uncovered dataset detailing the systems installed at over 2300 hospitals, the results...

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...

This study measures the impact of information technology (IT) use on hospital operating costs during the late 1980's and early 1990's. Using a proprietary eight-year panel dataset (1987-1994) that catalogues application-level automation for the complete census of the 3,000 U.S. hospitals with...

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 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 introduces new estimates of recent productivity developments in the United States, using an appropriate theoretical framework for aggregating industry MFP to sectors and the total economy. Our work sheds light on the sources of the continued strong performance of U.S. productivity...

We study the role of labor market mismatch in the adjustment to a trade liberalization that results in the offshoring of high-tech production. Our model features two-sided heterogeneity in the labor market: high- and low-skilled workers are matched in a frictional labor market with high- and...

This paper examines the relative importance of global, country-specific, and industry-specific factors in both the cash flow and discount rate components of equity returns between 1995 and 2003. Our framework draws upon previously separate literatures on country versus industry effects and...
