The Impact of Computers on Productivity in the Trade Sector: Explorations with Dutch Microdata

Trends in productivity, labor, and investment in the retail and wholesale trade sectors for the Netherlands in the 1988-94 period are examined. The analysis is based on a longitudinally linked panel of firms from the annual survey of Production Statistics collected by Statistics Netherlands (CBS). We find that computer investments have a positive impact on productivity and that the productivity impact of computers is greater in retail than in wholesale trade. There are a number of possible reasons for this finding, including greater penetration of computers in wholesale trade and differences in the way computers are deployed in the two sectors. Contrary to studies in the U.S., however, the impact of computer capital is about the same as other forms of capital. Differences in empirical specifications arising from the absence of data on capital suggest some caution with respect to this conclusion. We also find increased use of "flexible" employment practices, particularly among retail firms, and these appear related to computer use. As expected the measured impacts of computers on productivity are quite sensitive to the particular deflator used for computer equipment.

ICT and productivity in Europe and the United States

The surge in labour productivity growth in the United States in the late 1990s has prompted much speculation about the capacity of Information and Communication Technologies (ICT) to structurally increase growth. The simultaneous slowdown in productivity growth in the EU suggests the European countries are falling behind. In this paper we will analyse labour productivity growth in 51 industries in Europe and the United States. Using shift-share techniques we identify the industries in which the U.S. has gained a lead and the underlying reasons for this. The results show that the U.S. has grown faster than the EU because of a larger ICT producing sector and faster growth in services industries that make intensive use of ICT. Lagging growth in Europe is concentrated in wholesale and retail trade and the securities industry.

"Changing gear" : productivity, ICT and services: Europe and the United States

This paper examines cross-country and cross-industry differences in labor productivity performance and their association with ICT. It broadens earlier work with coverage of 52 industries in 16 OECD countries. The analysis suggests that ICT diffusion in Europe is following similar industry patterns to those observed in the U.S., but at a considerably slower pace. The key differences between Europe and the U.S. are in the intensive ICT-using services, with U.S. productivity growth showing a strong acceleration during the second half of the decade, whereas growth stalled in the EU. More specifically, the U.S. showed rapid productivity expansion in retail and wholesale trade and securities, which account for much of the overall U.S.-EU gap in productivity growth since 1995. In the ICT-producing sector, computers and communication equipment showed strong productivity growth and acceleration in virtually all countries, but differences are much bigger across countries for ICT-producing services, such as telecom services.

The Effects of Federalism and Privatization on Productivity in Chinese Firms

This study offers empirical evidence about how the structure of government and private ownership affects productivity in Chinese firms. It uses the microdata of China's most recent decennial industrial census, covering all of the 23,000 large and medium industrial firms operating in China during 1995. The results show that government decentralization – 'federalism' – plays an important role in improving the performance of not just collective firms, but also state-owned and mixed public/private ownership firms. This result is strongly confirmatory of much of the recent theoretical work on transition economies that posits a key role for government in the efficient operation of markets. Privatization makes a big difference in performance for firms administered at the federal level, especially state-owned enterprises. Private ownership also makes a large difference for wholly foreign-owned firms, nearly all located in special districts. In local jurisdictions, however, there is little difference in productivity across the various nonstate ownership types, supporting the argument that the regulatory environment played a critical role in successful business performance.china productivity microdata ownership decentralization

The Composite Index of Leading Economic Indicators: How to Make It More Timely

A major shortcoming of the U.S. leading index is that it does not use the most recent information for stock prices and yield spreads. The index methodology ignores these data in favor of a time-consistent set of components (i.e., all of the components must refer to the previous month). An alternative is to bring the series with publication lags up-to-date with forecasts and create an index with a complete set of most recent components. This study uses tests of ex-ante predictive ability of the U.S. leading index to evaluate the gains to this new 'hot box' procedure of statistical imputation. We find that, across a variety of simple forecasting models, the new approach offers substantial improvements.

International Comparisons of R&D Expenditure: Does an R&D PPP Make a Difference?

Purchasing power parities (PPPs) for R&D expenditure in 19 manufacturing industries are developed for France, Germany, Japan, the Netherlands and the United Kingdom relative to the United States for the years 1997 and 1987. These PPPs are based on R&D input prices for specific cost categories and differ substantially from current practice of comparing R&D expenditure using GDP PPPs and deflators. After taking into account differences in the relative price of R&D labor and materials, separate PPPs for other R&D cost categories are less essential, and a simpler version using GDP PPPs for these other categories should suffice. Our preferred PPPs are used to compare international R&D costs and intensity. The results suggest that the efforts devoted to R&D in each country are more similar across countries than is apparent using the nominal R&D intensities that are currently the norm.
