ICT capital and labour productivity growth: A non-parametric analysis of 14 OECD countries

This paper uses a new set of country data for 14 countries, members of the OECD, and a non-parametric approach to provide new evidence on the impact of Information and Communication Technology (ICT) on labour productivity growth between 1995 and 2005. For the first time, in the present paper a bootstrap approach for the decomposition of labour productivity change, proposed by Kumar and Russell (2002), is employed. This approach permits to conduct statistical inference on the parameters of interest, and to analyse the effects of ICT technologies on capital accumulation. The results confirm the role of ICT as a general purpose technology that needs organisational and business process changes to fully exploit its growth opportunities. The paper also finds out, by applying a non-parametric test, that ICT technologies positively contribute to the generation of convergence clubs in the evolution of labour productivity. Finally, the empirical evidence offers some basic guidance for future policy intervention in supporting ICT capital investments.     

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.     

Driving information communication technology for tax revenue mobilization in Sub-Saharan Africa

This study explores whether increasing Information and Technology Communication (ICT) boosts government revenue mobilization for sustainable development in 48 Sub-Saharan African countries from 2004 to 2020. While total tax revenue non-resource as a percentage of GDP and tax revenue as a percentage of GDP are used to proxy for tax revenue mobilization, three ICT measures are used, namely; the telephone penetration rate, the mobile phone penetration rate and internet penetration rate. To perform the analysis, we adopt the Generalized Method of Moments (GMM). The empirical findings are as follows. First, while the calculated net impacts are substantially positive, the corresponding marginal ICT effects utilized for calculating net effects are extremely negative. Second, an extensive study is carried out to determine complementing policy thresholds. These thresholds include: 21.959 (per 100 people) telephone penetration for total income from tax revenue; 16.333 (per 100 people) internet penetration for total income from tax; 21.125 internet penetration (per 100 people) for the income from the tax on non-resource income. This study has policy relevance, and implications as the penetration of the ICT rate can be influenced by policies to mobilize government revenue effectively.     

Financial development,ICT diffusion and economic growth: Lessons from MENA region

This paper aims to test jointly two economic puzzles: the effect of financial development and Information and Communication Technology (ICT) on economic growth. Theories predict a positive effect of financial development and ICT on growth but empirical studies on these relationships produced mixed results. Further, we investigate the interaction between financial development and ICT Diffusion to test whether the impact of financial development on growth is strengthened by better ICT infrastructure. In this paper we assess empirically these relationships in some MENA countries. The empirical study is based on estimation of a dynamic panel model with system GMM estimators. There are three main findings. First, our empirical results join empirical literature that find a negative direct effect of financial development on economic growth. This ambiguous relationship may be linked to many phenomenons but there are not yet clear explanations of this puzzle. Second, the estimates reveal a positive and significant direct effect of ICT proxies on economic growth. This implies that MENA countries need to reinforce their ICT policies and improve using of new Information and Communication Technology. Finally, the interaction between ICT penetration and financial development is found positive and significant in the growth regression. This implies that economies in Mena region can benefit from financial development only once a threshold of ICT development is reached.     

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.     

Foreign direct investment,information technology and economic growth dynamics in Sub-Saharan Africa

The research assesses how information and communication technology (ICT) modulates the effect of foreign direct investment (FDI) on economic growth dynamics in 25 countries in Sub-Saharan Africa for the period 1980–2014. The employed economic growth dynamics are Gross Domestic Product (GDP) growth, real GDP and GDP per capita while ICT is measured by mobile phone penetration and internet penetration. The empirical evidence is based on the Generalised Method of Moments. The study finds that both internet penetration and mobile phone penetration overwhelmingly modulate FDI to induce overall positive net effects on all three economic growth dynamics. Moreover, the positive net effects are consistently more apparent in internet-centric regressions compared to “mobile phone”-oriented specifications. In the light of negative interactive effects, net effects are decomposed to provide thresholds at which ICT policy variables should be complemented with other policy initiatives in order to engender favourable outcomes on economic growth dynamics. Practical and theoretical implications are discussed.     

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.     

ICT and economic growth in Sub-Saharan Africa: Transmission channels and effects

Despite significant progress in the empirical analysis of the impact of information and communication technology (ICT) on economic growth, previous studies have not empirically examined the mechanisms by which ICT hinders or expands economic growth. The specific aim of the present study was to identify the transmission channels through which ICT contributes to economic growth. The examined channels included; openness, FDI inflows, education, domestic investment, political institution, and inflation. The study employed the panel-corrected standard errors (PCSE) and system two step system GMM techniques on a sample of 44 countries in Sub-Saharan Africa (SSA) over the period 2004–2020. Using an ICT composite index, the causal mediation analysis identified that ICT contributed directly to growth, as proposed by the growth theories. Furthermore, the same analysis identified; domestic investment, openness, and education as crucial variables through which ICT penetration indirectly promoted per capita growth in the SSA region. The robustness of this result was verified using a variety of tools. The present findings suggested that the current efforts to expand ICTs in Sub-Saharan Africa should be continued since this sector has a considerable indirect impact on promoting economic growth.     

Do ICTs drive wealth inequality? Evidence from a dynamic panel analysis

Surprisingly, little is known about the cross-country effect of information and communication technology (ICT) on wealth inequality. At the same time, there is some tentative evidence suggesting that information and communication technology is positively correlated with income inequality. However, whether and how ICT affects wealth inequality is less explored, particularly because of the lack of reliable data on wealth inequality. This paper, therefore, fills this gap and contributes to this new literature by investigating the effect of ICT on wealth inequality in a sample of 45 developed and developing countries over the period 2000–2017. ICT is measured with six different indicators (including internet penetration, mobile penetration, ICT service exports, the ICT index, ICT quality, and ICT quantity), while wealth inequality is measured with three different indicators (comprising billionaire wealth to GDP, the Top 1% wealth share, and the Top 10% wealth share). The empirical analysis is based on the Generalised Method of Moments, and the results show that ICT increases wealth inequality. Furthermore, we show that democracy mitigates the increasing effect of ICT on wealth inequality. This result suggests that improving democracy in both developed and developing countries is an effective mechanism for mitigating the effects of ICT on wealth inequality. Therefore, we encourage efforts to implement democratic institutions that ensure respect for citizens' freedoms, greater democratic accountability, and executive constraints that allow for a more egalitarian distribution of wealth.     

Characterizing and comparing the evolution of the major global economies in information and communication technologies

In this paper, we characterise and compare status and evolution of the ICT industry of the six major global economies in ICT: China, the EU, Japan, Korea, Taiwan and the USA. For this, we employ official data covering the period 2006–2009. Our analysis shows that although the EU is the largest economy of the world, it is the least ICT-specialised economy of all six major ICT economies. The USA is clearly the top global player in ICT in many respects. In both ICT Manufacturing and ICT Services it has the largest Value Added, BERD, BERD intensity and labour productivity. We further observe that China has, by far, the largest number of employees in both ICT Manufacturing and Services, while its level of ICT BERD remains low. China is however an emerging economy and economic indicators of its ICT sector have strongly grown from 2006 to 2009. Japan׳s ICT sector has a larger weight in the national economy than those of the USA, EU, and China. Moreover, it is the country from which the highest number of ICT patent applications originate. We also find that, of all six major global economies in ICT, Taiwan and Korea have the most ICT-specialised economies, with a strong orientation towards Manufacturing. Finally, we discuss selected results of our analysis and conclude the paper with tentative policy implications for the EU.     

The globalization and stagnation of the ICT sectors in European countries: An input-output analysis

Recent studies of European countries indicate that the contribution of the ICT sectors to the regional economy is weakening and slowing economic growth. The present study investigates the contribution of the ICT sectors to economic performance in the European economies using Input–Output (IO) methodology. The results indicate that: (1) the multiplier effect of the ICT sectors on the rest of the economy declined significantly during the period 2000–2005 compared with 1995–2000; and (2) the decline in the output of the ICT sectors can be attributed to the loss of export advantages and technical change gains in the sectors. The results show an inability of the sectors to grasp the international market, most likely a consequence of the lack of anticipation of more rapid innovation in emerging countries.     

Technical efficiency and use of information and communication technology in Spanish firms

The literature concerned with the relationship between performance and information and communications technology (ICT) is usually focused on the ICT investments. This paper shows that it is the level of use of ICT within organisations, with preference as regards the expenses of ICT, which is responsible for the effect on performance. A general sample of 2255 Spanish companies has been used. Firms’ performance is measured as technical efficiency, which is determined by a data envelopment analysis (DEA), in which special attention is paid to the problem of the outliers. Finally, the analysis of the level of use of ICT is focused on a key area of the organisations, the supply chain, which affects the technical efficiency of the firms analysed. Results show that there is evidence of a positive effect of the use of ICT on technical efficiency. This effect is especially notable at intensive use levels in activities related to operations/manufacturing, purchasing or sales.     

Information communications technology and economic growth in Sub-Saharan Africa: A panel data approach

This research empirically analyzed the impact of mobile phone and the Internet on per capita income of Sub-Saharan Africa (SSA) for the period of 2006–2015 using a panel data of 40 countries. We have employed the robust two-step system GMM. Results showed that growth in mobile phone penetration has contributed significantly to the GDP per capita of the region after controlling for a number of other variables. A 10% increase in mobile phone penetration results in a 1.2% change in GDP per capita. Therefore, improving access to mobile phones will play a critical role in reducing the poverty level of the region through raising the per capita income of the population.However, the Internet has not contributed to the per capita GDP during the study period. The insignificant impact of the Internet could be due to low penetration of the technology, low ICT skill of Internet users, lack of or insufficient local content on the global network, and the relatively immature state of the technology in the region. Therefore, governments and other stakeholders should design policies that encourage expansion of the Internet. In addition to improving Internet access, policies which focus on ICT skill development and local content creation should also be designed and implemented.     

Digital divide and financial development in Africa

This paper analyses the influence of the digital divide on the new IMF financial development index on a panel of 34 African countries over the period 2005–2017. Using the instrumental variables technique, we arrive at the main result that ICT divide is a severe handicap for the financial systems development in Africa. The use of financial development sub-indices relating to financial institutions and financial markets, as well as their dimensions confirms the negative effect of the digital divide. Our result remains stable when we use alternative measures of financial development and ICT indicators. Furthermore, we found that the digital divide between countries is also a severe handicap for the financial development of countries lagging behind. On the other hand, countries with a technological lead or a digital dividend have relatively developed financial systems. Some recommendations have been suggested to promote digital penetration in Africa, as well as to improve the receptivity and flexibility of African financial systems.     

Access to and penetration of ICT in rural Thailand

This paper presents an econometric study of information and communication technology (ICT) in all 70,000 rural villages in Thailand, where the ICT considered consists of fixed-line telephone service, mobile telephone service, public telephones, computers, and Internet service. The results may provide information that helps policymakers decide where to put limited resources to promote ICT, and helps profit-seeking ICT companies target regions that maximize revenues. The study found that education is far more important than income in predicting the percentage of households who adopt ICT services, and that some unexpected variables such as the penetration of pickup trucks are useful predictors as well. Even in areas where fixed-line phone service is available, 70% of households with computers choose not to become Internet subscribers, although many presumably have enough money and technical knowledge. By separating availability from penetration of ICT, the study found that they can have different predictors, which means that researchers who do not separate them may get misleading results. There is no evidence showing mobile telephone service as a substitute for fixed-line telephone service. Also, public telephone service had little or no impact as a substitute for fixed-line or mobile telephone service, so phone companies need not fear that deployment of more public telephones will decrease their subscribership. Finally, there appears to be significant unmet demand for telephone service in rural Thailand where the infrastructure does not yet exist.     

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.     

ICT investment and GDP growth: Causality analysis for the case of Korea

This study investigated how investment in the industry of Information, Communication and Technology (ICT) has been interlocked with the GDP growth of South Korea. Based on seasonally-adjusted quarterly time-series data for the period between 1999 and 2016 available from the Korea Statistical Information Service, a Vector Error Correction model was applied for the analysis. The results revealed that ICT investment and GDP growth affected bi-directionally except for the short-run case in which only ICT investment affected GDP growth. The results explain that ICT investment plays an important role in the economic growth of South Korea in the long term; at the same time, investment size in the ICT industry increases as the economy grows. Without controlling any other factors, we found GDP increases by 0.4% when ICT investment increases by 1%. However, in the short term, only ICT leads to GDP growth. Therefore, the recent stagnation in ICT investment experienced in South Korea could negatively affect the economic growth of Korea in the short run, and hence, in the long-run, if it should become prolonged. The ICT investment strategy revealed from this study is especially useful to policy-makers who plan the economic growth in South Korea and other ICT-advanced countries because promoting ICT utilization across all sectors requires putting legal and policy mechanisms in place.     

Digital assemblages: evidence and theorising from the computerisation of the US residential real estate industry

We develop the concept of digital assemblages in order to advance current theorising on the ways in which information and communication technologies (ICTs) are helping to reshape work. The empirical setting is the US residential real estate industry—a ‘living laboratory’ for studying information‐intensive work and the adoption and uses of ICT. We find that real estate agents' uses of ICT are pervasive and suggest that agents now embed themselves more deeply into the transacting of real estate by actively supporting buyers and sellers, rather than acting primarily as information intermediaries. Building from this, we theorise that this ICT use can more coherently be understood as a ‘digital assemblage’ rather than a formal information system. Digital assemblages are characterised as distinct patterns of ICT collections that, in use, are functionally equivalent and structurally similar, relying on standardised and commodified ICT and are neither formally designed nor collectively governed.     

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.
