ICT as a source of output and productivity growth in Finland

This paper analyses the impacts of information and communications technology on output and labour productivity growth in Finland in 1995–2005. Information and communications technology (ICT) accounted for 1.87 percentage points of the observed labour productivity growth at the average rate of 2.87 per cent. The contribution from increases in ICT capital intensity was 0.46 percentage points. The rest is attributed to multi-factor productivity growth in ICT production, especially in telecommunications production. The ongoing outsourcing of ICT production to low-wage countries provides a threat to productivity performance in the future. Policy makers should consider where the next wave of productivity growth will come from.     

The long-run impact of Information and Communication Technology on economic output: The case of Australia

This paper investigates the cointegration and causal relationships between Information and Communication Technology (ICT) and economic output in Australia using data for about five decades. The framework used in this paper is the single-sector aggregate production function, which is the first comprehensive approach of this kind to include ICT and non-ICT capital and other factors to examine long-run Granger causality. The empirical evidence points to a cointegration relationship between ICT capital and output, and implies that ICT capital Granger causes economic output and multifactor productivity, as does non-ICT capital.     

Productivity of Singapore's Manufacturing Sector: An Industry Level Non-Parametric Study

This paper seeks to measure and to explain the productivity of Singapore's manufacturing sector using industry level data. It utilises a non-parametric approach consisting of a set of production distance functions, each of which is obtained by solving a linear programming problem. From a time-series of 1983 to 1993, across thirty industries, we obtain three indices: a Malmquist total factor productivity (TFP) index, an efficiency change index, and a technological change index. The resulting TFP growth stands at 4.6% per annum, considerably greater than previous estimates using aggregate country level data. Three-stage least squares are then applied to the pooled data. Foreign ownership and labour quality are found to have important impact on TFP growth.     

Information technology and its changing roles to economic growth and productivity in Australia

In this paper we describe our investigation of the role of investment in information technology (IT) on economic output and productivity in Australia over a period of about four decades. The framework used in this paper is the aggregate production function, where IT capital is considered as a separate input of production along with non-IT capital and labour. The empirical results from the study indicate the evidence of robust technical progress in the Australian economy in the 1990s. IT capital had a significant impact on output, labour productivity and technical progress in the 1990s. In recent years, however, the contribution of IT capital on output and labour productivity has slowed down. Regaining the IT capital productivity therefore remains as a key challenge for Australia, especially in the context of greater IT investment in the future.     

Does ICT investment widen the growth gap?

This paper builds a model of cumulative growth to examine the dynamic interdependent relationship between Information and Communication Technology (ICT) investment and economic growth for a sample of 29 countries in the 1990s. We confirm the following facts: First, there is a positive correlation between ICT investment and economic growth. Second, non-ICT investment has as much influence on the growth gap as ICT investment. Third, those countries with a solid economic infrastructure and open trade regime experience more active ICT investments. Fourth, those countries with a comparatively lower productivity level can reduce the gap using knowledge spillovers from more advanced countries. Fifth, reinforcement of patent rights has a positive influence on economic growth by stimulating the accumulation of ICT capital. Finally, ICT investment does not have a strong interdependent relationship with economic growth, while non-ICT investment has a cumulative causal relationship with economic growth and plays a key role in the process of widening the growth gap.     

ICT investment-specific technological change and productivity growth in Korea: Comparison of 1996–2005 and 2006–2015

This paper analyses the impact of information and communications technology (ICT) on the productivity growth in Korea with the dynamic general equilibrium (DGE) model including investment-specific technological change. According to the balanced growth path analysis, ICT investment-specific technological change accounts for 18.8% to labor productivity growth in 1995–2005, then 14.3% in 2006–2015, and the decline in the rate of ICT investment-specific technological change has contributed to the slow productivity growth since the mid-2000s. In cyclical fluctuations, ICT investment-specific technological shocks were significant in output variance in 1996–2005, but neutral technological shocks and non-ICT investment specific shocks became dominant in 2006–2015. In sum, it can be concluded that the impacts of ICT investment-specific technology have diminished in the growth path and cyclical fluctuations. The result that increased (decreased) ICT investment intensity with faster (slower) ICT investment-specific technological change lead to higher (lower) productivity growth indicates that Korea has been a case against the productivity paradox, and sustained technological progress in ICT and expansion of ICT usage could have boosted the productivity growth. Therefore, this study implies that facilitating ICT progress and ICT usage outside of the already well-performing ICT manufacturing can help Korean economy raise the productivity growth rate.     

Does ICT create a new driving force for manufacturing?—Evidence from Chinese manufacturing firms

The Internet has changed the global economic landscape. In particular, the fast-changing Information and Communication Technology (ICT) has directly led to a far-reaching impact on the production and operation of firms. Many previous studies have discussed the relationship of ICT and the total factor productivity (TFP) of firms, but failed to reach a consistent conclusion. This paper, based on the data of Chinese listed manufacturing firms from 2010 to 2019, explores the impact of ICT on manufacturing firms' TFP and its mechanism, and concludes that ICT have positive correlation with the TFP of manufacturing firms. According to the estimated results of this paper, TFP will increase by about 1.8 % for every 1 % of additional ICT investment. Through channel analysis, this paper finds that the positive effect can be achieved through the following four channels: cutting information search costs, enhancing information processing capabilities, reducing internal capital misallocation, and promoting R&D efficiency. This paper is a supplement to research on firm TFP, provides new micro-evidence for exploring the relationship between ICT and TFP of manufacturing firms, and brings important implications for understanding the role of ICT in firm production activities.     

Do R&D and ICT affect total factor productivity growth differently?

We analyze the effect of ICT and R&D on total factor productivity (TFP) growth across different industries in Sweden. R&D alone is significantly associated with contemporaneous TFP growth, thus exhibiting indirect effects. Although there is no significant short-run association between ICT and TFP, we find a positive association with a lag of seven to eight years. Thus, R&D affect TFP much faster than ICT-investments. We also divide ICT capital into hardware and software capital. To our knowledge, this distinction has not been made in any previous study analyzing TFP at the industry level. The results show that lagged hardware capital services growth is significantly associated with TFP growth. Hence, investments complementary to hardware are needed to reap the long-run TFP effects from reorganizing production.     

Total factor productivity enablers in the ICT industry: A cross-country firm-level analysis

Advancements in productivity in the digital economy constitute an important engine for economic growth. What drives productivity dynamics in the information and communication technology (ICT) sector? This study examines the productivity dynamics of ICT firms across countries from the perspective of corporate balance sheets. We study the effects of intangible assets and leverage on productivity growth using firm-level panel data from five industrialized countries. We find that intangible assets positively affect the total factor productivity in the ICT sector. The positive effect of intangible assets on total factor productivity growth is larger for ICT manufacturing firms than for ICT service firms. We also find that leverage has a positive relationship with total factor productivity development in the ICT sector. In addition, our empirical results substantiated that productivity is catching up to the technological frontier. Furthermore, larger firms and/or younger firms generally show higher total factor productivity growth than their peers. Economies of scale are more prominent in the ICT service sector than in the ICT manufacturing sector. Our findings contribute to the understanding of cross-country productivity dynamics in the ICT sector at the firm level in the digital economy.     

Intangible capital,ICT and sector growth in China

This paper explores how intangible capital affects the growth of ICT-intensive sectors in China by examining 29 sectors in 30 regions for the years 2003–2015. It is shown that the value added in ICT-intensive sectors in China will grow faster in regions with faster development of intangible capital. This effect is robust to alternative measures of intangible capital and ICT intensity indicators, and even if other region-level determinants of sector growth such as human capital, non-ICT physical capital and financial market development are taken into consideration. The findings imply that Chinese policy makers should aim for not only more ICT investment but also the development of intangible capital.     

Information and communications technology infrastructure and firm growth: An empirical study of China's cities

Despite the importance of information and communications technology (ICT), previous studies of the business value of information technology have yielded mixed results. This study provides new empirical evidence that demonstrates the impact of cities' ICT on firm performance. A series of panel datasets are assembled to measure the improvement of city's ICT infrastructure and the change of firm performance during the years 2001–2016 in China. The findings demonstrate that city's ICTs positively promoted firm performance, including financial profitability, marketing performance and innovation performance. Instrumental variables are employed to verify the positive impact of city's ICTs infrastructure on firm profitability. Taking advantage of an exogenous variation of telecommunications upgrade as a natural experiment, this study uses the difference-in-difference approach to establish causality between cities' ICT infrastructure and firm profitability. Mechanisms are explored, which shows that better labour quality, lower costs and higher transparency are the three possible channels through which ICTs influence firm profitability.     

The role of ICT in Korea’s economic growth: Productivity changes across industries since the 1990s

This paper investigates the hypothesis that technological convergence has been a major driving force for the recent productivity increase in Korea. Based on the dynamic panel data of Korean industries, the direct impact of information and communication technology (ICT) on labor productivity is assessed through growth accounting, and the indirect network effect of ICT on industrial total factor productivity (TFP) is estimated. The results confirm the essential role of broadband networks for successful convergence. The policy implications for the regulatory change are drawn from the empirical analysis.     

From Network Externalities to Broadband Growth Externalities: a Bridge not yet Built

Quantifying the impact of new technologies on economic activity has proven notoriously difficult. Indeed, it has taken decades of research to understand confidently the linkages between the advances in information, communications, and technology (ICT) spawned by the personal computer and aggregate economic activity. Today, the rapid deployment of broadband technology presents economists with this same challenge. In this paper, we explore the foundations of network and growth externalities that are associated with broadband deployment. We find that both theoretical and empirical models that better specify the micro-transmission paths in which broadband are likely to enhance economic output, employment and productivity are needed.     

The decoupling between labour compensation and productivity in high-income countries: Why is the nexus broken?

During the last decades, mature economies have tended to experience a divergence between labour compensation and productivity growth. Interpretations of this trend are still under debate. Our article aims at contributing to a sound, evidence-based understanding. We estimate the magnitude of this decoupling for a panel of 22 high-income economies (1970–2018) and empirically assess the role of a variety of factors. After providing evidence that casts doubt on the impact of technical change, we adopt a ‘political economy’ standpoint and focus on the structural effects on real compensation growth of several macroeconomic and institutional dimensions. Our findings indicate that labour market slack and the weakening of pro-labour institutions have acted as important wage-squeezing factors. A negative effect is also found for trade openness and international capital mobility, while most financialization variables are not significant. The robustness of our results is supported by a range of tests and specifications.     

Development of telecommunication and broadcasting infrastructure indices at the global level

The importance of information and communication technology (ICT) in economic development has been increasing rapidly along with the Internet and mobile telecommunication networks. ICT development is becoming a main growth factor of many countries. As they realize the importance of the ICT industry, developing nations work to catch up with established economies. Therefore, many nations are formulating an ICT-enhanced policy. This paper introduces a number of telecommunication and broadcasting sub-indices, which include the fixed telephone network, the Internet, and mobile networks, which are aggregated into a composite Telecommunication Index (TI). The indices are computed using principal component analysis and human development type index methods. The country rankings, by different ICT-related indices, help identify the strengths and weaknesses of infrastructure development such that each country can foster economic growth. The performance of TI is compared with several other indices, such as the digital access, human development, and ArCo technology indices. The type of indices affects the country ratings. Results suggest that the parametric index approach may be preferred over those methods in which the subjective weighted summation of normalized variables used (non-parametric indices).     

Convergence and determinants of ICT development in case of emerging market economies

This paper aims to examine the convergence of ICT development in the case of 27 emerging market economies (EMEs) using annual data from 2000 to 2018. First, by employing Phillips-Sul (PS) panel convergence test, the results not only support the evidence of convergence in ICT development but also find convergence in the composition of ICT development known as ICT access and ICT use. Second, the study identifies factors such as per capita income, human capital, and FDI which significantly affect ICT development. Third, results based on stochastic conditional convergence reveal that EMEs countries are not only converging among themselves but also ‘catch-up’ to the OECD countries.     

ICT Co-evolution and Korean ICT strategy—An analysis based on patent data

This paper investigates the interactive nature of relationships between Information and Communications Technologies (ICTs) in terms of their technological innovations and diffusion. For the purpose, the United States Patent and Trademarks Office (USPTO) database was used and Lotka-Volterra equations were applied to the patent data, resulting in a Patent Interaction Network (PIN). This matrix was employed to investigate the interaction patterns among ICT-related industries, allowing co-evolution process across ICTs to be analyzed. This paper also examined patenting activities in the Korean ICT sector, which has announced the IT839 strategy to address ICT-related services, infrastructures and growth drivers. It is judged that the evolving pattern of Koran ICT has been compatible with the PIN, facilitating the development of each other. It is also expected that promoting broadband and home-network technologies, together with technologies on digital contents and software solutions, can lead to the growth of the whole ICT industry. Such research findings will provide numerous implications for policy-making and strategic planning for ICT development.     

The gender pay gap in the ICT labour market: comparative experiences from the UK and New Zealand

This paper addresses the issues surrounding gender pay gaps focusing on the Information Communication Technology (ICT) sector of the labour market. Reporting on research conducted in the UK and New Zealand (NZ) we adopted a mixed method approach using comparable qualitative and quantitative research techniques to investigate pay issues amongst women working in ICT in the UK and NZ. Our findings reveal commonalities of experience and some interesting differences. Unlike with the UK sample, for example, in NZ women working in ICT do not believe that their pay reflects their workload, skills and their position within their own organisation. Our study found that non‐transparent pay and reward systems and salary secrets exacerbate inequality and discrimination in the UK and NZ. The paper concludes by offering some policy directions to encourage a narrowing of the gender pay gap and reflects on the benefits of doing cross‐national research.     

Is technological change really skill‐biased? Evidence from the introduction of ICT on the Italian textile industry (1980–2000)

This paper investigates the effects of the introduction of information and communication technologies (ICT) on the skills of a workforce. Using micro-data collected from workers in the textile sector, we analyse whether the introduction of ICT has modified workers' tasks, so that higher skills and longer training periods than before are necessary. Empirical evidence suggests that the adoption of ICT has no universal skill-biased effect for all occupations at least in the textile sector.     

Evaluating internal and external knowledge sources in firm innovation and productivity: an industry perspective

Both internal knowledge – investment in internal R&D and information and communication technologies (ICT) as well as external knowledge – knowledge spillovers and active collaboration with partners are rapidly fostering firm productivity and innovation. In this study, we investigate the role of internal and external knowledge in firm productivity and innovation. In addition, we test interactions between investment in R&D and ICT as well as between knowledge spillovers and knowledge collaboration in their association to firm innovation and productivity. We use a recombinant innovation approach and four samples for firms in manufacturing, creative, ICT and science, and professional services industries during 2002–2014 and for pre-and post-crisis periods to perform our analysis. In addition to innovation and productivity, we also examine the role of internal and external knowledge as a conduit to the development of innovation internally and the co-creation of innovation with external partners. Our results lead to managerial and policy implications.
