Evolution and determinants of digital divide in Brazil (2005–2013)

During the last decades, the widespread growth of information and communication technologies (ICT) has posed incentives to broaden the participation of individuals in social, political and economic dimensions of life. However, utilization of ICT also involves access to technology and infrastructure, and acquisition of skills to deal with innovations and, thus, digital literacy is, primarily, a complementary good. The digital divide expresses inequalities in access and utilization of ICT among individuals and populations in different countries. The study adopts inequalities indexes of Internet access and mobile phone ownership to measure use of ICT goods, accounting for the digital divide in Brazil. The inequality indexes are also split according to main determinants using four nationally representative survey data from 2005 to 2013. Results indicate that the digital divide among individuals is decreasing quite fast among Brazilians over time. However, there is room for policies of mass access to ICT goods based on mobile Internet broadband access. In addition, digital illiteracy, evaluated by lack of education, is one of the main determinants of the digital divide in the country, especially among elderly individuals.     

Digital knowledge generation and the appropriability trade-off

The introduction of information and communication technologies (ICT) has changed in depth the organization of the generation of knowledge reducing significantly knowledge absorption cost and improving knowledge interactions. The digital generation of knowledge relies on the systematic access and use of the stock of quasi-public knowledge. ICT enable to reconsider the knowledge appropriability trade-off as it helps to better appreciate the positive role of knowledge spillovers in the recombinant generation of new knowledge, next to the well-known negative effects of the limited appropriability of knowledge on revenues and hence incentives to innovate. This new analytical framework calls for an augmented role of telecommunications policy that should take into account the positive effects of knowledge connectivity on the generation of knowledge.     

Being a woman in an ICT job: an analysis of the gender pay gap and discrimination in Spain

Despite policy initiatives aimed at promoting female access to jobs, the information and communication technology (ICT) professions have traditionally been largely monopolised by men. Segregation, gendered stereotypes and environmental factors have a clear impact on educational and professional choices, as well as on working conditions. The spread of ICT to all economic activities has meant that ICT specialists are now to be found everywhere, not only in the ICT sector where many stereotypes related to technical jobs persist. This work aims to analyse the gender wage gap and discrimination in ICT professions, with the emphasis on how working in an ICT-intensive industry might affect that situation. The study uses the Spanish Earning Structure Survey data for 2014, and applies wage decomposition techniques to the wage distribution. The results show that female ICT professionals face unfavorable working conditions, especially in highly qualified jobs and in ICT-intensive industries.     

An index for cross-country analysis of ICT infrastructure and access

The purpose of the present article is to devise an index for measuring and analyzing the divide among countries in the area of information and communication technology (ICT) infrastructure and access. Understanding the fact that there are many factors influencing the digital divide, this research is not intended to measure the digital divide in terms of different inequalities, but it rather attempts to take only one of the most important of these factors (maybe the most important of them) into consideration for measuring and analyzing divide between countries, that is, ICT infrastructure and access. In contrast to the majority of the indices in this context, the proposed index is built upon defining and conceptualizing ICT infrastructure and access. In addition, the index uses core ICT indicators on which the international community and experienced modelers have consensus that they measure the information society suitably. Therefore, the index can be exploited as the basis and standard for internationally comparable statistics in ICT infrastructure and access area. Moreover, it is the second index based on core ICT indicators after the Digital Opportunity Index (DOI) that was developed by the International Telecommunication Union (ITU) in 2005. However, in the current article, using Data Mining methods, Markov Chain Monte Carlo (MCMC) (to impute missing data) and Multi-Stage Factor Analysis (FA) (for aggregating the indicators), many problems and limits of the existing indices, the DOI in particular, such as the lack of data for analyzing ICT infrastructure and access, use of equal weighting or experts’ opinions to aggregate the indicators, are avoided. Since this index is developed by statistical procedures, it is flexible, adaptable, and modifiable over time while it sustains its original structure. It is comprised of two main dimensions: ‘ICT access’ and ‘coverage of mobile and access tariffs’ and 10 indicators. Finally, comparing the proposed index with the other indices in this field and gross national income (GNI) per capita of 150 countries, this index is tested; then, it is utilized to measure and analyze the divide between countries in the two dimensions, different geographical areas, economic conditions, and levels of ICT infrastructure and access.

ICT-specific technological change and economic growth in Korea

This study investigates the role of information and communication technology-specific technological change in Korea's past and future. The contribution of information and communication technology (ICT) to past economic growth through embodied technology in intermediate inputs and investment goods is revealed by the growth accounting methodology, which considers quality adjustment. Relative prices between ICT-related products and other goods provide an indirect measure for identifying embodied technologies. Meanwhile, ICT's contribution to future economic growth is examined via policy simulations using the computable general equilibrium model. The results imply that ICT has grown Korea's economy and that policy measures for increasing ICT investment are required for continued sustainable growth.     

Antecedents and consequences of logistics value: And empirical investigation in the Spanish market

In business practice and the academic study of logistics, the incorporation of concepts such as quality followed by value has been truly revolutionary. In addition, the use of information and communication technologies (ICT) has substantially modified the way inter-company relationships are managed. This has meant that logistics is no longer considered a routine, merely operational activity but a strategic variable which is a deciding factor in achieving customer satisfaction. There are, however, still a large number of companies which continue to ignore the differentiating potential of logistics and consider it to be a routine activity. Our contribution comes within the framework of this new perspective which is analysed on the basis of an emerging concept: logistics value. The objective of this study is to contribute to the knowledge on what logistics value consists of and how it is formed, in business to business (B2B) relationships in particular. On the basis of a theoretical framework obtained from the literature review of perceived value from a trade-off perspective, we carry out an empirical analysis to determine the antecedents and consequences of logistics value. Our results, through SEM analysis show that ICT, the benefits derived from supplier-customer relationship, logistics service quality and the sacrifices associated to logistics service delivery in terms of costs, contribute to creating logistics value which is the antecedent to the classic satisfaction-loyalty chain.     

Measuring convergence of China's ICT industry: An input-output analysis

The convergence of the information and communication technology (ICT) industry is ubiquitous phenomena, which can be classified from the supply/demand side or complementary/substitute relation. According to the classification, the paper measures the convergence of China's ICT sectors based on its 2002 input-output (IO) table, including five manufacturing sectors and two service sectors. Then, using IO table cross-entropy updating technique, the paper investigates the convergence evolution of four ICT manufacturing sectors from 1997 to 2002. The research finds the following conclusions. In 2002, the supply side convergence of manufacturing sectors was higher than that of service sectors, while service sectors featured a higher degree of the demand side convergence. The year of 2002 witnessed high complementary convergence between some China's ICT manufacturing and service sectors. During the period from 1997 to 2002, the supply side convergence dominated the convergence of China's ICT industry, while the demand-side convergence experienced little structural change.     

Does information and communication technology improve job satisfaction? The moderating role of sales technology orientation

Empirical research concerning the role of information and communication technology (ICT) in shaping business-to-business salesforce job satisfaction remains relatively scarce. The authors propose and empirically test a causal model that theoretically represents structural relationships among factors comprising ICT and eventual salesperson job satisfaction. Study results indicate that ICT indirectly influences job satisfaction through salesforce administrative performance. While ICT infrastructure, training, and support positively relate to administrative performance, none of them influence outcome performance significantly. In addition, salesperson technology orientation moderates the effect of both ICT infrastructure and support on job satisfaction. Managerial insights and implications from the research are discussed.     

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.

Disparities in ICT adoption: A multidimensional approach to study the cross-country digital divide

This paper presents a cross-country study on the determinants of information and communication technology (ICT) diffusion using multivariate analysis techniques to capture the relative and multidimensional character of digital divide. Using canonical correlation analysis, the differences detected between groups of countries both in terms of ICT patterns and in terms of the factors explaining each are compared. The results provide the ability to distinguish between different patterns of ICT adoption that can be explained primarily by variables associated with differences in development levels. In countries registering higher levels of ICT adoption, the digitalization pattern is explained by GDP, service sector, education, and governmental effectiveness. In contrast, in developing countries, population age and urban population are positively associated with the ICT adoption, while Internet costs impact negatively. The results might be useful in finding and implementing the most suitable telecommunication and development policies for each case.     

A multi-criteria game theory and real-options model for irreversible ICT investment decisions

The information and communication technology (ICT) industry is one of the most capital intensive among the high-technology industries. ICT business analysis, especially after the industry deregulation, has become a difficult task. Traditional quantitative cost–benefit analysis concerning investment decisions is by no means sufficient for capturing the complexity of the problem in its entirety. This work combines quantitative and qualitative analyses for modeling competitive interactions between players in the ICT business field. The proposed decision analysis model combines real options, game theory, and analytic hierarchy process for analyzing ICT business alternatives under the threat of competition. The proposed model is applied to a real broadband technology business case, showing how it can be formulated and solved.     

Induced effects of smart food/agri-systems in Japan: Towards a structural analysis of information technology

The Japanese government decided to promote “smart society” in the 5th Science and Technology Basic Plan. The purpose of this research is to evaluate the effects of information and communication technology (ICT) in smart society by input-output analysis using the food industry and agriculture as examples. We define food production and agricultural activities utilizing ICT as a smart food-agri system, and try to analyze the effect of such a system on the economy as a whole. As a result, we confirmed that such a system has a large economic ripple effect on information sectors. At the same time, through these analyses, (1) we redefine information goods and service sectors, (2) we describe the new management sectors that are using these goods and services, but are not currently independent businesses, and (3) we clarify new industrial structure that exists in “smart society” using ICT.     

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.     

Assessment of information and communications technology maturity level

The use of information and communications technology (ICT) turned out to be a key factor in the process of the wider development of a country. It is therefore very useful to estimate ICT evolution by the means of an appropriate metric. Based on statistical data from 159 countries, the ICT maturity level index (IMLI) is proposed and estimated by using structural equation modelling (SEM). This index is a metric measuring the information society in a country and consists of three sub-indices which are access, use and skills. It is an improvement of the ICT development index, proposed by the ITU in 2009. The analysis divides the countries into two groups, the developed and the developing, due to major disparities in their statistical data. The criterion used to define the groups was the income, as expressed by the Gross National Income per capita. The impact of a number of influential parameters on the ICT maturity level is evaluated and it becomes obvious that there is a substantial difference in their impact between developed and developing countries. Finally, a procedure that allows the ranking of the countries, based on IMLI, is presented.     

Intraorganizational information and communication technology diffusion: Implications for industrial sellers and buyers

Information and communication technologies (ICTs) like CRM, ERP and Intranet are considered important for creating competitive advantage. Despite their rapid deployment rates, only a few studies mainly from the information technology (IT) and engineering literature have been devoted in uncovering the factors that influence the diffusion of new information technologies within an organization. Similarly, empirical studies regarding the impact of ICT diffusion on organizations are strikingly limited. In an attempt to fill this research void, the present study examines the implementation of ICT tools within marketing-related and non-marketing-related functions. By testing a number of hypotheses using structural equation modeling, the authors conclude that the antecedents and consequences of ICT diffusion in these functions vary. Their findings provide the foundation for a more thorough examination of both intraorganizational diffusion of ICT tools as well as their impact on organizations.     

Can one laptop per child reduce digital inequalities? ICT household access patterns under Plan Ceibal

The study of information and communications technology (ICT) adoption signals that diffusion processes within highly unequal societies produce stratification in the access to digital technologies and thus, maintain or even increase previous socioeconomic disparities. While technological utopians believed that One Laptop Per Child (OLPC)-like programs could reduce societal inequalities, the economics literature evaluating these initiatives has mostly focused on student's human capital. Results suggest no impact, even for successful programs such as Uruguay's own OLPC-inspired Plan Ceibal. In this paper, we use an event-study approach to difference-indifferences to identify the impact of Plan Ceibal on the household adoption of technological goods across income quintiles. Our results show that Plan Ceibal helped to bridge domestic digital disparities in terms of access to PC and favored the uptake of internet services. We discuss the potential mechanisms behind these results. Regarding household PC access, even though Plan Ceibal was conceived as a universal program targeting primary-level students attending public schools, both infantilization of poverty and a dual-system educational stratification may explain why this initiative had a heterogenous impact across different income groups. Regarding household connectivity, Plan Ceibal reduced the cost of the bundle required to consume internet services at the time of the study, improving affordability and access among households with beneficiaries of the program.     

Boundary management in an ICT‐enabled project‐based organising context

This paper explores the boundaries that emerge and exist within an information and communication technology (ICT)‐enabled project‐based organising context and the ways knowledge workers manage these boundaries through the use of technology. This is done through an exploratory qualitative case study of an early instance of the phenomenon in a knowledge‐intensive professional services organisation. Through the experiences of a group of knowledge workers who started to work in project‐based ways that were highly mediated by ICT, this study aims to understand the boundaries that they faced and the practices they undertook to manage these boundaries. In so doing, this study contributes to the existing literature on new forms of work and organisation, particularly on the issue of boundaries where ICT‐enabled project teams are used. In particular, this study extends our current understanding of boundaries through expanding the lens of investigation beyond a predominant focus on work–home boundaries and considers boundaries within the work sphere.
