The economic impact of mobile broadband speed

Based on panel data of 116 countries in 2014–2019, this paper investigates the association between mobile broadband speed and labor productivity. It finds no robust contemporaneous relationship for the total sample, but there is a significant and robust association when a one-year lag of mobile broadband speed is introduced. The interpretation of the results is that a 10 percent increase in mobile broadband speed in period t-1 is associated with 0.2 percent increase in labor productivity, ceteris paribus. The results are only robust for non-OECD and low-income countries, respectively.     

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.     

ICT as a source of economic growth in the information age: Empirical evidence from the 1996-2005 period

This paper examines the hypothesis that ICT penetration has positive effects on economic growth. On theoretical grounds, this paper discusses three channels through which ICT penetration can affect growth: (i) fostering technology diffusion and innovation; (ii) enhancing the quality of decision-making by firms and households; and (iii) increasing demand and reducing production costs, which together raises the output level. This paper conducts three empirical exercises to provide a comprehensive documentation of the role of ICT as a source of growth in the 1996-2005 period. The first exercise shows that growth in 1996-2005 improved relative to the previous two decades and experienced a very significant structural change. The second exercise uses the traditional cross-country regression method to identify a strong association between ICT penetration and growth during 1996-2005, controlling for other potential growth drivers and country-fixed effects. The third exercise uses the system Generalized Method of Moment (GMM) for dynamic panel data analysis to tease out the causal link between ICT penetration and growth. This analysis also shows that, for the average country, the marginal effect of the penetration of internet users was larger than that of mobile phones, which in turn is larger than that of personal computers. The marginal effect of ICT penetration, however, lessens as the penetration increases. This paper points out several policy implications drawn from its analyses and findings.     

ICT as a driver of economic growth: A survey of the literature and directions for future research

This paper conducts a comprehensive literature survey of the papers that examine the link between ICT and economic growth. Using a rigorous screening framework, we found 208 academic papers that were published from 1991 to the cutoff date of October 30, 2018.This survey provides a robust set of insights into the distribution, research strategies, and findings of the surveyed papers, taking into account their geographic focus and type of ICT-growth links. This study also reveals the key factors that predict the citation impact by paper. Among the directions for future research, this paper argues that the time has come for the research on the ICT-growth link to shift its main focus from evidencing its positive relationship to advancing the understanding on why and how emerging digital technologies directly or indirectly affect economic performance.     

Small is big in ICT: The impact of R&D on productivity

We examine the contribution of R&D to firm productivity in a large panel of European firms and study its variation with the age, size, and sub-sector of firms. We find that R&D capital in ICT firms has a larger effect on revenue when compared to non-ICT firms. At the firm level, our results suggest that, surprisingly, smaller and older ICT firms benefit the most from R&D. Small but mature ICT firms are likely to dominate market niches, and small size may enable them to be flexible and adaptable which helps them respond to technological opportunities to develop innovative products and services. This has important implications for public policy based upon firm age.     

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.     

The economic impact of broadband on growth: A simultaneous approach

This paper investigates how broadband penetration affects economic growth. A macroeconomic production function with a micro-model for broadband investment is used to estimate the impact of broadband infrastructure and growth. The results indicate a significant causal positive link especially when a critical mass of infrastructure is present. The scope of this research is 22 OECD countries based on data collected for the period 2002–2007.     

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.     

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.     

ICT for sustainable development: Global comparative evidence of globalisation thresholds

The objectives of this paper are to investigate the effect of ICT on sustainable development and the mechanisms through which the effect is modulated. The focus is on a sample of 140 countries around the globe for the period 2000–2019. The methodology involves the: (i) Fixed Effects estimator to control for individual heterogeneity, (ii) Driscoll and Kraay estimator to control for cross-section dependence between panels, (iii) the Mean Group estimator to take into account the averages between panel groups, (iv) the system GMM to correct for unobserved heterogeneity and simultaneity bias and (v) the instrumental variable Fixed Effects Tobit to take in to account the limited range in our dependent variable. The results show that ICT has a positive and significant effect on sustainable development. Whereas overall net effects are positive, the findings are contingent on the choice of the ICT measurement, the geographical location of the economy and the income group category. The study recommends policy makers to take into account ICT and the advantages it offers in the elaboration of measures for the sustainable development agenda.     

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.     

Dynamic competition in technological investments: An empirical examination of the LCD panel industry

When are technological laggards more likely to try to catch up with leaders? We offer empirical evidence on firm-level data of plant investments in the TFT-LCD panel industry, where technological competition has been intense and dynamic. We find that the followers' level of technology has a non-monotonic effect on technology-improving investments, with intermediate followers the most apt to invest in catch-ups. This result is a puzzle given the existing theory on technology race. We also find that followers' catch-up investments increase with the capacity of the leader that employs the state-of-the-art technology. These results are robust to variations in specification and alternative accounts of effects. We discuss our findings and contributions in light of the technology race literature.     

ICT technologies in Europe: A study of technological diffusion and economic growth under network theory

The sector of Information and Communication Technologies (ICT) is one of the key instruments for the development of an economy. The literature emphasizes its capacity for both increasing productivity and generating new sources of income and wealth (5 and 20 among others). Traditionally studies on the ICT sector have focused on the analysis of its economic impact, but not on its capacity as a “bridge” for information and knowledge flows across the economic network. Following Burt's approach (1992) on structural holes, the organization of the economic network defines where and for whom new opportunities lie. The structural hole methodology allows to analyze the capacity of the ICT sector as an enabler of technological diffusion and innovation. The results show that the European ICT sector not only is important for its intermediary role in the flow of information across the economic network, but also for its low level of dependency on other sectors.     

The differential impact of ICT on employees: narratives from a hi‐tech organisation

This paper draws upon findings from a case study, which examined the implementation of information and communication technologies within a hi‐tech organisation. It explores how technology became embedded within the organization, altering working practices. It concludes that embedding technology needs to be undertaken at an individual level to be successful.     

The impact of regional ICT development on job quality of the employee in China

The paper matches the province-level ICT development with the micro-level data of the China Family Panel Studies (CFPS), uses multiple indicators to measure ICT development and job quality, and investigates the impact of regional ICT development on job quality of the employee. The research conclusions are as follows: First of all, ICT development has a significant positive impact on job quality of the employee. After a series of robustness tests and dealing with endogeneity issues, the research conclusion continues to be valid. Second, when the job quality of the employee is poor, the promotion of ICT development is relatively strong. Third, ICT development has an indirect impact on job quality through the Internet awareness. Finally, ICT development has a relatively strong role in promoting job quality of women, older, non-agricultural, and medium-skill employees. From the policy perspective, in order to improve the job quality of the employee, we suggest promoting ICT development, narrowing the digital gap, increasing investment in education, and taking into account the different characteristics of employees.     

Evaluating the effects of ICT core elements on CO2 emissions: Recent evidence from OECD countries

This research aimed to inform policymakers about the actual climate relevance of the information and communication technology (ICT) ecosystem, which includes data centers and content provision, broadband networks, and consumer devices. To provide robust empirical evidence on the net environmental impact of these core ICT elements, we used OECD panel data for 34 Member States for the years 2002–2019 and panel fixed-effects regression models. In contrast to previous literature, we measured basic broadband and new fiber-based wireline broadband and 3G/4G mobile broadband network deployment. We also captured variations in end-user devices, ICT affinity, and famous online content. We found that, on average, the CO₂-reducing effects appear to outweigh the CO₂-increasing effects. In particular, we found that, in addition to the reduction effect associated with the use of basic broadband connections, there is a further, albeit smaller, reduction effect associated with new fiber-based broadband connections. Other ICT elements showed insignificant coefficient estimates, suggesting largely offsetting environmental impacts. Our main findings were subject to various robustness checks and were broadly consistent with previous literature using data from developed countries. Our results suggested that old and new broadband networks as enabling technology could generate positive environmental effects for society.     

The selected determinants of manufacturing postponement within supply chain context: An international study

Modern supply chains focus on an ultimate consumer satisfaction and often require essential dynamic reconfiguration. Manufacturing companies constitute important central nodes in supply chains, where almost all physical flows are concentrated.Postponement is the operating concept, which aims at delaying activities until a customer’s order has been received. The growth of interest in the postponement concept partially results from the increased demand for customized products.Data for the analysis has been collected through the survey carried out by researchers in several countries. The main research instrument used for this research was a questionnaire developed by the Global Manufacturing Research Group (GMRG). The conclusions formulated on the basis of data analysis proved that market and demand characteristics do not seem to be important for the choice between postponement and speculation strategy. The research showed that assembly postponement depends mostly on managerial decisions about the goals of company and the level of acceptance of an assembly postponement strategy on the market. Full postponement strategy is dictated mainly by the level of product customization and capacities of manufacturing and logistics systems. Production postponement has to be accepted on the market and should be associated with excellent forecasting techniques.     

Digitalization and economic growth: A comparative analysis of Sub-Saharan Africa and OECD economies

This paper examines the contribution of digitalization to economic growth of Sub Saharan Africa (SSA) in comparison with the Organization for Economic Cooperation and Development (OECD) economies. The main reason for comparing the most and the least developed countries to measure the effects of digitalization is to have an insight of whether such effects depend on the levels of development of the country. New technologies in Sub Saharan Africa are assumed to have played significant roles in economic activity, including accessibility of communications, which was impeded by poor infrastructure, accommodation of the poor majority who were initially financially excluded from mobile banking and participation of small and medium enterprises (SMEs) in e-commerce. On the other hand, due to the effects of digitalization, least developed countries in SSA have been facing a premature deindustrialization.This study employs a panel dataset consisting of 11 years from 2006 to 2016 for 41 SSA and 33 OECD economies and we use the generalized linear methods of moments (GMM) estimators. The results show that digitalization has a positive contribution to economic growth in both groups of countries. The effect of broadband internet is minimal for SSA compared to OECD countries, whereas the impact of mobile telecommunications is higher in SSA compared to the OECD counterpart. These results are particularly interesting as less advanced technologies create more opportunities in the least developed countries since there is more space for improvement. With respect to policy implications, this study recommends that SSA governments should invest more in ICT along with other infrastructures, so as to benefit from digitalization and to realize significant economic growth.     

On the regional impact of broadband on productivity: The case of Brazil

This paper analyses the incidence of broadband on regional productivity in Brazil, intending to find out if the economic impact is uniform across all territories of the country. The possibility of performing a regional approach to test the effect of broadband on productivity in an emerging country represents a novelty for the literature. Results suggest that the impact of broadband on productivity is positive although not uniform across regions. On the one hand, it seems to depend on connection quality and network effects. Faster download speed and critical-mass accounting for network externalities in the region enhance the economic impact of broadband. On the other hand, higher productivity gains are estimated for the less developed regions. The fact that the less productive regions in Brazil seem to be benefiting more from broadband may suggest that it can constitute a factor favoring regional convergence in the country.     

The system-wide impact of healthy eating: Assessing emissions and economic impacts at the regional level

Encouraging consumers to shift their diets towards a lower meat/lower calorie alternative has been the focus of food and health policies across the world. The economic impacts of such changes on regions have been less widely examined, but are likely to be significant, especially where agricultural and food production activities are important for the region. In this study we use a multi-sectoral modelling framework to examine the environmental and economic impacts of such a dietary change, and illustrate this using a detailed model for Scotland. We find that if household food and drink consumption follows healthy eating guidelines, it would reduce both Scotland’s “footprint” and “territorial” emissions, and yet may be associated with positive economic impacts, generating a “double dividend” for both the environment and the economy. The economic impact however depends critically upon how households use the income previously spent on higher meat/higher calorie diets. Furthermore, the likely (but not modelled) benefits to health suggest the potential for a “triple dividend”.
