New technologies and productivity growth in the euro area

This paper provides an overview of the available evidence on the importance of information and communication technologies (ICT) for developments in average labour productivity (ALP) growth in the euro area. The contribution of ICT to ALP growth is found to have increased both in terms of production and investment over the 1990s (up to 2001). However, there is no evidence of significant positive spillover effects from the use of ICT on ALP growth. This implies that there is no reason to believe that potential output growth in the euro area has increased significantly in recent years on account of new technologies. Comparing developments in the euro area and the United States, it appears, however, that ICT capital cannot account for much of the difference in ALP developments over the 1990s. This suggests that cyclical developments and, in particular, the structure of the economy are more important for explaining the difference in performance.First version received: March 2002/Final version received: May 2003We thank Bart van Ark, Neale Kennedy, Gerard Korteweg, Ad van Riet, Marcel Timmer, two anonymous referees and participants at the 17th Congress of the European Economic Association, Venice August 2002 for their comments.

Towards an information economy : The case of Singapore

Recent empirical studies have documented the emergence of information-based economies in developed countries within Europe, the U.S.A., Japan, and Australia. Casual observations suggest that the newly industrializing country of Singapore is proceeding towards a similar trend. The primary purpose of this paper is to account for the share of Singapore's national product which originates from informational activities. In particular, we define and estimate the size of Singapore's information sector within an input-output framework. Our results indicated that a sizable portion of Singapore's economy is information-based. In view of the significant penetration of informational activities in economic production, advances in communication technology and concomitant improvements in information-handling capabilities are bound to affect factor productivities and incomes with consequences for a country's pattern of employment and production structure. It is anticipated that an economics of communication becomes necessary for an awareness of communication technology as a choice variable in economic planning. We conclude our discussion with an assessment of the admissability of an information sector concept in economic analysis and the usefulness of empirical studies based on such a concept.     

Technological innovations and economic prosperity: A time series analysis

Using a univariate decomposition of per capita real GDP into its permanent trend and irregular components, the objective of this paper is to measure, rank, and compare the relative importance of the major technological innovations of the past two centuries as measured by their contribution to the growth rate of real per capita GDP. The paper uses the growth model and Beveridge and Nelson’s (1981) univariate decomposition method to measure and to compare the economic impact of random technological shocks, as measured by the average increase in real per capita GDP during sub-periods of major technological advancements.     

Schumpeterian and semi‐endogenous productivity growth explanations

This paper examines the nature and sources of productivity growth in South African manufacturing sectors, from an international comparative perspective. On panel data estimations, we find that the evidence tends to support Schumpeterian explanations of productivity growth for a panel of countries including both developed and developing countries, and a panel of South African manufacturing sectors. By contrast, semi‐endogenous productivity growth is supported for a panel of OECD (Organisation for Economic Cooperation and Development) manufacturing sectors. However, we also report evidence that suggests that sectors are not homogeneous. For this reason, time series evidence may be more reliable than panel data. Time series evidence for South Africa suggests that prospects for the sustained productivity growth associated with Schumpeterian innovation processes, is restricted to a narrow set of sectors. For the OECD manufacturing sectors, both semi‐endogenous and Schumpeterian growth finds support. Schumpeterian growth is present for a larger number of sectors than for South Africa, and is most prevalent in the North American economies.     

Population distribution,effective area and economic growth

The usual measure for the factor land is the total area. But total area is a flawed measure because land is of unequal quality. To account for land quality, we use an alternative measure called effective area. Effective area is based on spatial population distribution which captures both natural conditions and human activity. Theoretically, effective area explains economic growth better than total area that biases the measure of total factor productivity (TFP) growth. Empirically on the basis of 40 years of panel data for the United States, an increase of 10% in effective area is associated with an economic growth of 5%, and the omission of effective area undervalues the growth of TFP by 8.1%.     

Markups,productivity and external market development of the service SMEs

During the last decade, economists and policy makers have extensively discussed what types of firms can exploit external markets by exporting and what happens to domestic firms if external competitors penetrate into the home market. Although both theoretical and empirical studies have been dedicated to these issues, few have been carried out for the service sector. Since the service sector accounts for the lion’s share of GDP, the lack of those studies indicates that a large part of the actual economy still remains veiled. Our study fills this gap. We examine whether or not the Melitz and Ottaviano (2008) model remains satisfied in the service sector, using data from Japanese SMEs. From our analysis, we confirm that larger market sizes are associated with higher productivity levels. On the other hand, firms with higher markups tend to develop their business in smaller markets, conditional of the simultaneity between production and consumption. These results reveal that further productivity growth in the service sector also requires markets to be larger and more integrated. In addition, the markup levels become lower in those markets.     

Total factor productivity convergence across the Kazakh regions

This article examines total factor productivity (TFP) convergence across the regions of Kazakhstan over the period of 1997–2013. Using a growth accounting methodology we found that the average level of TFP fell by almost 40% over the period under consideration. Several panel unit root tests confirm that the whole set of Kazakh regions and the group of non-oil regions converged in terms of TFP, while the group of oil-rich regions diverged. This result explains sigma-divergence of the GRP per capita across the regions of Kazakhstan by divergence in capital intensity.     

Three levels of education and the economic growth

The aim of this article is to solve the question how the three main stages of education contribute to the labour productivity growth in selected 125 countries in the period 1999–2014. The model is based on the neoclassical production function enhanced with human capital. The authors draw on the Penn World Tables 9.0 and UNESCO databases. The key benefit of this article is that human capital is characterized according to the returns to education from average number of years of formal schooling at the primary, secondary and tertiary level. Based on the panel data analysis, the contributions of capital and of the three levels of education to the growth of labour productivity are estimated. At the same time, the model allows to estimate the contribution of total factor productivity. The results of the analysis show that tertiary education has the strongest impact on labour productivity across the considered economies. At the same time, the breakdown of aggregate human capital by level of education leads to better clarification of the effects of human capital and physical capital on labour productivity. The conclusions also indicate a tendency towards rising returns to scale induced by the secondary and tertiary education.

Informational mobility and productivity: Finnish evidence

The labor productivity effects of portability and connectivity of information and communication technology (ICT) are studied with Finnish firm-level data. It is found that a computer with only processing and storage capabilities boosts labor productivity by 9% (corresponding to 5% output elasticity), portability by 32%, wireline connectivity by 14%, and wireless connectivity by 6%. The findings are in line with previous literature and comparisons to ICT costs suggest that firms equate marginal costs and returns. Although increasing ICT penetration can no longer be a major source of productivity growth in developed economies, the relatively new characteristics studied can.     

The effect of financial development on economic growth: a meta-analysis

In this article, we contribute to the current debate on the sign and size of the finance–growth relation. To this purpose, we use a meta-analysis with 551 estimates from 68 empirical studies that take private credit to GDP as a measure for financial development. We distinguish between linear and logarithmic specifications. First, we find evidence of significantly positive publication bias in both the linear and log-linear specifications. It suggests the literature has exaggerated the size of the finance–growth effect in the past. Second, we find suggestive evidence that the logarithmic specification is superior to the linear specification. In the logarithmic specification when accounting for publication bias, a 10% increase in credit to the private sector increases economic growth with 0.09 percentage points. For the linear estimates, no significant effect of credit to the private sector on economic growth is found on average. Overall, the evidence points to a positive but decreasing effect of financial development on growth and supports the ‘too much’ finance hypothesis.     

Hiding in Plain Sight: A Note on Public Goods,Information Technology,and Productivity

This research note advances a conjecture that may help to explain the “paradox” of productivity and information technology (IT). Conventional measures of the economic output of the IT sector may substantially understate the actual value of IT because software is a public good, which is largely unpriced. I provide a simple exploratory calculation that lends plausibility to this explanation. I hope that this conjecture may inspire research by those with greater expertise in the evolution of software.

Information Technology and the World Economy*

This paper addresses the impact of investment in information technology (IT) on the recent resurgence of world economic growth. We describe the growth of the world economy, seven regions and 14 major economies during the period 1989–2003. We allocate the growth of world output between input growth and productivity and find, surprisingly, that input growth greatly predominates! The contributions of IT investment have increased in all regions, but especially in industrialized economies and Developing Asia. Differences in per capita output are explained by differences in per capita input, rather than by variations in productivity.

Trade reorientation and post-reform productivity growth in Bulgarian enterprises

This paper analyzes the importance of integration into world markets following the collapse of central planning in explaining the productivity growth performance of Bulgarian firms. Using a large panel data set on 1,300 manufacturing firms for 13 quarters, we find that a shift towards sourcing from - and exporting to - OECD markets is a significant factor explaining firm-level total factor productivity growth.     

Government interventions and productivity growth

This article investigates the impact of government industrial policy and trade protection of the manufacturing sector in Korea. Empirical results are provided, using four-period panel data for the years 1963 through 1983, for thirty-eight Korean industries in which trade protection reduced growth rates of labor productivity and total factor productivity, while industrial policies, such as tax incentives and subsidized credit, were not correlated with total factor productivity growth in the promoted sectors. The evidence thus implies that less government intervention in trade is linked to higher productivity growth.     

Off-shoring and labor productivity: Evidence from China

This paper uses input-output tables to measure material off-shoring, service off-shoring and narrow sense material off-shoring on 33 industries by use of DJ index (Daveri and Jona-Lasinio, 2008), not FH index with “the same proportion assumption” (Feenstra and Hanson, 1996). It estimates the effects of the off-shoring on labor productivity by panel data model. Our results show that, the off-shoring is generally positively associated with labor productivity, and service off-shoring has more significant effect than the material off-shoring. There are some key aspects to be discussed in detail, including: (1) the heavy industry’s material off-shoring increases obviously and service off-shoring declines in recent years, and the former’s contribution to productivity growth is less than the latter; (2) the demand of chemical industry for service off-shoring significantly increases and its positive marginal effect on productivity growth is stronger than the material because of industry transformation and upgrading; and (3) the current intensive material off-shoring of textile, equipment manufacturing industries greatly contributes to productivity growth, while the positive effect from service off-shoring on labor productivity has initially boomed. In conclusion, we provide some suggestions for further development of China’s off-shoring.     

The Output Contributions Of Computer Equipment And Personnel: A Firm-Level Analysis

This paper examines the output contributions of capital and labor deployed in information systems (IS) at the firm level during the period 1988–91 throughout the business sector, using two different sources of data on these inputs. Our production function estimates suggest that there are substantial excess returns to both IS capital and IS labor. Computer capital and labor jointly contribute, or account for, about 21 percent of output, although only about 10% of both capital and labor income accrue to IS factors. Although IS employees accounted for a very small share of total employment by 1986, IS employment growth is estimated to have made a larger contribution to 1976–86 output growth than non-IS employment, due to the very rapid growth (16% per annum) of IS employment. The estimated marginal rate of substitution between IS and non-IS employees is 6: one IS employee can be substituted for six non-IS employees without affecting output.
