Information Technology and Productivity Growth in the 2000s

Abstract. US productivity growth experienced continued productivity growth after 2000 even as investment, particularly in information technology (IT), slowed. This paper uses industry-level data to examine the link between average labor productivity (ALP) growth and IT in the post-2000 period. We use difference-in-difference and cross-sectional regressions to show that the link between ALP growth and IT-intensity is weaker after 2000 than before. These results are robust to alternative measures of IT-intensity such as the IT share of capital services, the level of IT capital depth, and the share of IT capital services in total output. We conclude that the post-2000 productivity gains in the United States do not appear to have been driven directly by IT.     

Of Yeast and Mushrooms: Patterns of Industry-Level Productivity Growth

Abstract. In this paper we analyse labour productivity growth in the United States, four European countries (France, Germany, the Netherlands and United Kingdom), Australia and Canada between 1987 and 2003 from an industry perspective. Rather than analysing broad industry groups, we compare the pattern of growth in all industries through Harberger diagrams. We introduce new summary measures, which indicate the pervasiveness of growth patterns. These indicators show that investment in both information and communication technology (ICT) and non-ICT capital is fairly balanced or 'yeasty', driven by overall macro-economic conditions. However, growth of total factor productivity (TFP) is much more localized or 'mushroom-like'. In particular we find a clear distinction between countries in continental Europe, in which TFP is decelerating after 1995 and becoming more localized, and Anglo-Saxon countries in which TFP growth is accelerating and becoming more broad-based, especially after 2000. The increased breadth of Anglo-Saxon TFP growth is consistent with delayed effects of intangible investments that are complementary to ICT investments.     

Business cycle and level accounting: the case of Portugal

This paper studies what accounts for the recent business cycles phenomena in Portugal and why it is depressed relatively to the United States. The business accounting procedure applied here suggests that most of the changes in output per worker in Portugal over the period (mainly, from 1979 to 1991) can be attributed to changes in economic efficiency. For instance, the strong economic recovery in output per worker just after Portugal joined the European Union until the first years of the 1990s can be essentially attributed to improvements in economic efficiency. From 1979 to 2000, Portugal caught up with the industrial leader. Its output per worker is currently depressed by about 46% relative to the United States level (it was depressed by 57% in 1979). In the 1980s all of this depression in output per worker relative to the United States was due to the productivity factor. By 2000 Portugal depression relative to the United States was a mix of the French and Japanese depression. The labor factor accounted for roughly 24% of this depression, while the economic efficiency accounted by about 89%.      

Information and Communications Technology as a General-Purpose Technology: Evidence from US Industry Data

Abstract. Many people point to information and communications technology (ICT) as the key for understanding the acceleration in productivity in the United States since the mid-1990s. Stories of ICT as a 'general-purpose technology' suggest that measured total factor productivity (TFP) should rise in ICT-using sectors (reflecting either unobserved accumulation of intangible organizational capital; spillovers; or both), but with a long lag. Contemporaneously, however, investments in ICT may be associated with lower TFP as resources are diverted to reorganization and learning. We find that US industry results are consistent with general-purpose technology (GPT) stories: the acceleration after the mid-1990s was broad-based – located primarily in ICT-using industries rather than ICT-producing industries. Furthermore, industry TFP accelerations in the 2000s are positively correlated with (appropriately weighted) industry ICT capital growth in the 1990s. Indeed, as GPT stories would suggest, after controlling for past ICT investment, industry TFP accelerations are negatively correlated with increases in ICT usage in the 2000s.     

The structural transformation and aggregate productivity in Portugal

We document the substantial process of structural transformation—the reallocation of labor between agriculture, manufacturing, and services—and aggregate productivity growth undergone by Portugal between 1956 and 1995. We assess the quantitative role of sectoral labor productivity in accounting for these processes. We calibrate a model of the structural transformation to data for the United States and use the model to gain insight into the factors driving the structural transformation and aggregate productivity growth in Portugal. The model implies that Portugal features low and roughly constant relative productivity in agriculture and services (around 22%) and a modest but growing relative productivity in manufacturing (from 44 to 110%). We find that productivity growth in manufacturing accounts for most of the reduction of the aggregate productivity gap with the United States and that a further closing of this gap can only be accomplished via improvements in the relative productivity of services.

Mind the Gap! International Comparisons of Productivity in Services and Goods Production

Abstract. In this paper, we make a comparison of industry output, inputs and productivity growth and levels between seven advanced economies (Australia, Canada, France, Germany, the Netherlands, United Kingdom and United States). Our industry-level growth accounts make use of input data on labour quantity (hours) and composition (schooling levels), and distinguish between six different types of capital assets (including three information and communication technology (ICT) assets). The comparisons of levels rely on industry-specific purchasing power parities (PPPs) for output and inputs, within a consistent input–output framework for the year 1997. Our results show that differences in productivity growth and levels can be mainly traced to market services, not to goods-producing industries. Part of the strong productivity growth in market services in Anglo-Saxon countries, such as in Australia and Canada, may be related to relatively low productivity levels compared with the United States. In contrast, services productivity levels in continental European countries were on par with the United States in 1997, but growth in Europe was much weaker since then. In terms of factor input use, the United States is very different from all other countries, mostly because of the more intensive use of ICT capital in the United States.     

ESTIMATES OF INTANGIBLE INVESTMENT BY INDUSTRY AND PRODUCTIVITY GROWTH IN JAPAN

In estimating intangible investment in Japan at the industry level, we find a high intangible investment/gross value added ratio in the information technology (IT) sector and negative growth rates in intangible capital in 13 industries over the decade from 2000. When we examine the impacts of intangible investment on total factor productivity growth, we find a significant and positive effect on total factor productivity growth in the market economy. In a revised estimation that considers intertemporal knowledge spillovers, the estimated rate of return on intangibles in the IT sector is quite high after the IT revolution. The results imply that intangible assets have been underinvested in the IT sector.     

PRODUCTIVITY GROWTH IN LATIN AMERICA OVER THE LONG RUN

The low pace of Latin American productivity growth in recent decades, despite extensive economic reforms, has yet to be understood in a longer‐run context where factors such as demographic changes, structural shifts, and investment levels can be taken fully into account. The OxLAD database provides comparable sectoral output and workforce series over 1900–2000 for the six leading economies in the region for the first time. Our analysis of this new dataset shows that: intersectoral resource reallocation reduced aggregate productivity growth in all three periods; total factor productivity growth was low throughout the century, and even negative in the closing three decades; and thus factor accumulation—investment in fixed capital and skilled labor—was the main source of productivity growth in Latin America during the twentieth century.     

Intangible Capital and Labor Productivity Growth: Panel Evidence for the EU from 1998–2005

Using new international comparable data on intangible capital investment by business within a panel analysis between 1998 and 2005 in an EU country sample, a positive and significant relationship between intangible capital investment and labor productivity growth is detected. This relationship proves to be robust to a range of alterations. The empirical analysis confirms previous findings that the inclusion of business intangible capital investment in the asset boundary of the national accounting framework increases the rate of change of output per hour worked more rapidly. In addition, intangible capital is able to explain a significant portion of the unexplained international variance in labor productivity growth, and becomes a dominant source of growth.     

Price caps and the error in X-factor calculations

Calculation of the X-factor used for price caps has a fundamental flaw when it is based on conventional growth accounting total factor productivity analysis. This error is discussed and the appropriate corrective action is indicated. In an example based on the X-factor used for determining the change in the price for local exchange carriers’ interstate access service in the United States, it is shown that the appropriate X-factor is about 25 percent greater than that based on conventional growth accounting total factor productivity analysis.

Accounting for human capital externalities with an application to the Nordic countries

Externalities caused by human capital accumulation have taken up considerable space in theoretical work on economic growth. However, less attention has been paid to this externality in traditional growth accounting exercises. This paper takes up the issue of growth accounting, suggesting a framework for quantifying human-capital externalities and illustrating it empirically using data from the five Nordic countries. Four sources of growth are identified, i.e. capital accumulation, labor force growth, and total factor productivity growth (TFP), where the traditional TFP measure is split into a part explained by human-capital formation and an unexplained part. By doing this I am able to attribute between 12 per cent and 33 per cent of growth in the Nordic countries to human capital investment.     

ICT and Growth: The Role of Rates of Return and Capital Prices

We revisit the widely discussed contribution of investment in ICT to economic growth, focusing on differences in productivity and quality of ICT across countries and time. In a growth accounting approach, we look at the way rates of return and rates of asset price decline measure these aspects. Conducting a sensitivity analysis with data from the EU KLEMS database for the years 1990–2007, we introduce a constant rate of return and a constant rate of ICT price decline. Both alternative measurements somewhat downplay the role investment played relative to growth in multifactor productivity in the U.K. and the U.S. during 1995–2000. Moreover, we show that more than half of the ICT contribution to labor productivity growth results from changes in capital quality and composition rather than from quantity.     

Will East Germany Become a New Mezzogiorno?

Despite massive regional policy efforts, GDP per capita in Southern Italy has only briefly converged on Northern Italian levels in the 1960's. Failure of convergence since then is associated with a policy switch from investment toward income maintenance, with reduced wage sensitivity to regional labor market conditions and with increases in rent-seeking opportunities and corruption. East Germany's early experience of rapid wage and income, but not productivity, convergence raised fears that aMezzogiornoscenario could be repeated. Since then, however, investment and productivity have risen while wage setting has become more flexible. Given East Germany's greater “social capability” for growth, and provided that investment continues to be encouraged, the prospects for convergence are now more promising.J. Comp.

Export Growth,Capacity Utilization,and Productivity Growth: Evidence from the Canadian Manufacturing Plants

Aggregate labor and multifactor productivity growth slowed substantially post‐2000 in the Canadian manufacturing sector. To examine the source of the decline, this paper proposes a decomposition method that delves deeper into the two micro‐components of aggregate productivity growth: a within‐plant component and a between‐plant component. The decomposition builds on earlier work by Jorgenson and his collaborators that decomposes aggregate productivity growth into its industry components, but applies it to the plant level and introduces non‐neoclassical features of the plant‐level economic environment. It finds that the preponderance of the aggregate labor and multifactor productivity growth slowdown is due to the pro‐cyclical nature of productivity growth arising from capacity utilization. Almost all of the aggregate productivity growth slowdown is driven by exporters, as exporters experienced large declines in labor productivity growth in the post‐2000 period as a result of large declines in their capacity utilization.     

Sectoral Productivity in the United States: Recent Developments and the Role of IT

Abstract. This paper introduces new estimates of recent productivity developments in the United States, using an appropriate theoretical framework for aggregating industry multi-factor productivity (MFP) to sectors and the total economy. Our work sheds light on the sources of the continued strong performance of US productivity since 2000. We find that the major sectoral players in the late 1990s pickup were not contributors to the more recent surge in productivity. Rather, striking gains in MFP in the finance and business service sector, a resurgence in MFP growth in the industrial sector, and an end to drops elsewhere more than account for the aggregate acceleration in productivity in recent years. Further, some evidence is found for a link between IT intensity and the recent productivity acceleration.     

Vintage Effects In Human Capital: Europe Versus The United States

The standard assumption in growth accounting is that an hour worked by a worker of given type delivers a constant quantity of labor services over time. This assumption may be violated due to vintage effects, which were shown to be important in the United States since the early 1980s, leading to an underestimation of the growth of labor input (Bowlus anA1d Robinson, 2012). We apply their method for identifying vintage effects to a comparison between the United States and six European countries. We find that vintage effects led to increases of labor services per hour worked by high-skilled workers in the United States and United Kingdom and decreases in Continental European countries between 1995 and 2005. Rather than a productivity growth advantage of the US and UK, the primary difference with Continental European countries was human capital vintage effects instead.     

CAN INVESTMENT IN INTANGIBLES EXPLAIN THE SWEDISH PRODUCTIVITY BOOM IN THE 1990s?

In the early 1990s the Swedish economy experienced a severe economic and financial crisis which resulted in a substantial GDP decrease. Even though the crisis was not a complete surprise for many economists, almost no one expected that the Swedish economy would be prospering with booming productivity growth only a few years later. Economists have presented three explanations for the fast recovery and productivity growth in 1995–2006: market reforms, crisis recovery, and the impact of ICT. This paper offers an alternative view, emphasizing instead firms' substantial investment in intangible assets such as R&D, design, and advertising. Based on the growth accounting framework, intangible capital accounted for more than 30 percent of the labor productivity growth in the Swedish business sector from 1995 to 2006. Thus, Swedish TFP growth, one of the highest among OECD countries, is reduced substantially when investment in intangibles is included in the growth accounting analysis.     

Information Technology and Productivity Changes in the Banking Industry

This paper analyses the effects of investment in information technologies (IT) in the financial sector using micro-data from a panel of 600 Italian banks over the period 1989–2000. Stochastic cost and profit functions are estimated allowing for individual banks' displacements from the best practice frontier and for non-neutral technological change. The results show that both cost and profit frontier shifts are strongly correlated with IT capital accumulation. Banks adopting IT capital-intensive techniques are also more efficient. On the whole, over the past decade IT capital-deepening contribution to total factor productivity growth of the Italian banking industry can be estimated in a range between 1.3 and 1.8 per cent per year.
