Economic growth and broadband access: The European urban-rural digital divide

This paper estimates the regional effects of high-speed broadband coverage on economic growth in a panel of 1348 regions across all European Union Member States between 2011 and 2018. We distinguish between different connectivity speed levels by aggregating the available regional data across all existing broadband technologies, and investigate how regional differences in the contribution of broadband coverage to real economic growth can quantitatively explain the persistence of the European urban-rural digital divide. In order to make our results robust to endogeneity and disaggregated data availability issues, we employ a bootstrap-based bias correction for the dynamic fixed effects estimator. We find that expansions in the provision of lower-speed broadband access accelerated annual per capita growth in both urban and rural regions through diminishing returns to scale, but that the effects were weaker in those regions characterized by larger ruralization. High-speed broadband coverage, on the contrary, could only be significantly related to rural economic growth and had no impact within their urban counterparts. We find evidence that the costs of these high-speed rural connectivity expansions had not yet been offset, but that they exhibit increasing returns to scale with cut-off levels nearing full coverage. These results indicate that the high-speed digital expansion of rural Europe is a potential gamechanger for further rural development policies through its role as a general-purpose infrastructure, and consequently argue in favour of increased efforts to close the urban-rural digital gap.     

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 impact of license duration on tangible investments of mobile operators

Using data from the WCIS (World Cellular Information Service) and the Telecoms Market Matrix of Analysis Mason, we were able to build a database relating the level of investment per capita to license duration for 14 countries over a 10-year period. An empirical analysis of the data shows a positive correlation between the tangible investment per capita and the license duration (the average of all active licenses or the latest license). More precisely, we observe an increase of €1.5 in the average investment per capita per year for each additional year of license duration. We also find no significant negative impact of license duration on mobile market competition. The competition outcomes are measured using the Lerner index at the operator level. Some robustness checks are performed at the country level by using the HHI (Herfindahl-Hirschman index) and the number of active mobile operators as measures of the level of competition, and we obtain additional results indicating once more that the competition is not negatively impacted by license duration.     

外部性与产业增长——来自中国省级面板数据的研究

本文利用我国29个省、市、自治区25个产业的面板数据研究了外部性对于地区产业增长的影响,结果发现:在全国样本范围内,专业化水平与产业增长之间存在着负向关系;竞争程度与地区产业增长之间存在着正向关系;多样化程度与产业增长之间存在着一种非线性关系,当多样化程度较低时,多样化不利于产业增长,而当多样化水平较高时,多样化则会促进产业增长。在分地区分产业的分析中,产业多样化水平对经济增长的作用在很大程度上取决于产业的性质(高度规模经济产业或低度规模经济产业)及产业的地理区位(沿海地区或内陆地区)。     

The rural telecommuter surplus in Southwestern Ontario,Canada

This paper asks the question: what kind of economic benefits do rural telecommuters experience in Southwestern Ontario? This is a relevant question in Canada where, according to Statistics Canada (2017) one in 14 people work from home. This paper presents an overview of the current literature on telecommuting. We estimate the telecommuter surplus in Southwestern Ontario where the region is currently deploying one of Canada's largest publicly-funded ultra-high-speed broadband initiatives known as SouthWest Integrated Fibre Technology Inc. (SWIFT). The analysis is based on SWIFT residential and farm surveys (n?=?3948) conducted in 2017. We find that an average telecommuter's surplus in terms of costs saved, including opportunity cost ranges from $8820 to $23964 per annum per telecommuter, depending on the number of days telecommuted per week for home and primary residence dwelling type. The social net benefits of telecommuting differ from its private net benefit (the focus of our paper) since the former includes both positive and negative externalities associated with telecommuting such as reduced traffic congestion, reduced probability of road accidents, as well as some workers shirking their duties (a negative impact). We leave this for future work.     

Is faster better? Quantifying the relationship between broadband speed and economic growth

In this paper, I aim to quantify the relationship between higher broadband speeds (10 Mbps versus 25 Mbps) and the growth rates in important economic outcomes in U.S. counties including jobs, personal income, and labor earnings. Doing so exposes the potential for severe selection bias in studies of broadband's economic impact, which is addressed in this study using Coarsened Exact Matching. Once balanced, the data reveal no economic payoff from the 15 Mbps speed difference between the years 2013 and 2015 (when data is available). I also revisit an early and widely-cited study on broadband's effect on employment to evaluate the possible impacts of selection bias, and conclude that the positive benefits of broadband reported in that particular study are likely spurious. The selection bias problem may infect other studies on the economic impacts of broadband Internet services. Future research on broadband's economic impact should explicitly address selection bias.     

Broadband speed and unemployment rates: Data and measurement issues

We examine the effects of broadband speed on county unemployment rates in the U.S. state of Tennessee. We merge the older National Broadband Map dataset and the newer FCC dataset in lengthening our broadband access data over the period 2011–2015. Extending the dataset improves the precision of the estimates. Our panel regressions control for potential selection bias and reverse causality and show that broadband speed matters: unemployment rates are about 0.26 percentage points lower in counties with high speeds compared to counties with low speeds. Ultra-high speed broadband also appears to reduce unemployment rates; however, we are unable to distinguish between the effects of high and ultra-high speed broadband. We document beneficial effects of the early adoption of high speed broadband on unemployment rates. Better quality broadband appears to have a disproportionately greater effect in rural areas.     

外商直接投资对城乡收入差距的影响研究——空间溢出及门槛特征

本文以我国30个省市2003～2014年的面板数据构建空间滞后模型和门槛面板模型,以人均国内生产总值和外商直接投资（FDI）强度为门槛变量,实证检验FDI与城乡收入差距间的非线性空间关系。结果表明FDI与城乡收入差距具有显著的空间积聚特征,同时FDI对缩小城乡收入差距的效应显著,且在各地区间存在明显差异。此外,FDI与城乡收入差距间具有门槛特征。当人均国内生产总值和FDI强度跨过门槛值时,FDI对于缩小城乡收入差距的效应会呈现出下降趋势。     

Estimating broadband diffusion in the EU using NUTS 1 regional data

In this paper we use panel data on NUTS 1 regional data for 27 EU countries in the years 2006–2010 to analyze determinants of broadband diffusion. We estimate both linear demand specification and the logistic diffusion function. We find that, after controlling for regional differences due to socioeconomic factors, inter-platform competition approximated by an inter-platform Herfindahl index has a significant positive impact on broadband diffusion. Broadband deployment is lower in countries in which DSL has a greater share in Internet access and it is higher in countries in which cable modem has a greater share in Internet access. Moreover, we find that competition between DSL providers has a significant and positive impact on broadband penetration. First, higher prices for a fully unbundled local loop connection, which represent the cost of providing copper-based Internet services, have a significant and negative impact on broadband penetration. Second, a greater incumbent share in DSL connections has a significant and negative impact on broadband penetration.     

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.     

Broadband access in the EU: An assessment of future economic benefits

This paper evaluates the net economic benefits that would derive from the implementation of the broadband infrastructure deployment targets by 2020 as entailed by the Digital Agenda for Europe Initiative set forth by the European Commission. As a first step, we estimate the returns from broadband infrastructure for the period 2005–2011, differentiating the impact of broadband by levels of adoption and speed while accounting for reverse causality and extensive heterogeneity. In the second step, the cost of broadband roll-out is assessed under different assumptions of technical performance and contrasted with the forecasted benefits that derive from increased broadband coverage. We find that in the base case scenario the overall future benefits outweigh the investment costs for the European Union as a whole for the highest performance technologies. This holds also for the majority of member states individually. We further extrapolate the returns by country under different scenarios of implementation. In most cases the benefits are substantially well above the costs. Private sector is reluctant to invest, as investors in broadband infrastructure only can partially appropriate benefits. This would suggest a rationale for the public sector to subsidize build-out of high speed broadband infrastructure.     

State broadband policy: Impacts on availability

We use a county-level panel dataset from 2012 to 2018 to assess the impacts of various state policies on total and rural broadband availability in the United States. The primary dependent variable is the percentage of residents with access to 25 Megabits per second (MBPS) download and 3 MBPS upload speeds via a fixed connection, with alternative specifications considering other aspects of availability such as technology type and competition. We control for the main determinants of Internet availability such as income, education, age, and population density. Our policy variables come from the newly released State Broadband Policy Explorer from the Pew Charitable Trusts and individual contacts from the nationwide State Broadband Leaders Network. Our primary policies of interest are those related to: (1) availability of state-level funding, (2) existence of a state-level broadband office/task force with full-time employees, and (3) restrictions on municipal/cooperative broadband provision. We find a positive and significant impact of state-level funding programs on general (and fiber) broadband availability, and a negative impact of municipal/cooperative restrictions. The findings are similar when the analysis is restricted to the rural portions of counties.     

Broadband adoption and availability: Impacts on rural employment during COVID-19

Amidst COVID-19-related stay-at-home orders, the economy moved largely online and broadband internet became more important than ever. This paper explores the relationship between broadband and employment rates during April and May 2020 in rural U.S. counties. We use two broadband dimensions: infrastructure availability rates and household adoption rates. We use a two-stage least squares approach to address endogeneity and control for socioeconomic, demographic, and pandemic-related factors. Results show broadband availability and wired broadband adoption both had significant, positive impacts on the employment rate. Our findings suggest both broadband adoption and availability may be associated with economic benefits in rural America.     

Co-determination, Efficiency and Productivity

We present the first panel estimates of the productivity effects of the unique German institution of parity, board‐level co‐determination. Although our data span two severe recessions when labour hoarding costs of co‐determination are probably highest, and the panel is too short to capture the likely long‐run benefits in terms of human capital formation and job satisfaction, we find positive productivity effects of the 1976 extension to parity co‐determination in large firms.     

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.     

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.     

Fiber-broadband-internet and its regional impact—An empirical investigation

I analyze a quasi-natural experiment of fiber broadband rollout in a rural German county and investigate the impact on real estate values. I find that there are strong and significant effects of fiber broadband deployment, which indicate relevant personal benefits for customers. These findings add to the literature on the evaluation of broadband infrastructure investment.

Effects of innovation on employment: A dynamic panel analysis

This paper estimates the effect of innovation on employment at the firm level. Our uniquely long innovation panel data set of German manufacturing firms covers more than 20 years and allows us to use various innovation measures. We can distinguish between product and process innovations as well as between innovation input and innovation output measures. Using dynamic panel GMM system estimation we find positive effects of innovation on employment. This is true for innovation input as well as for innovation output variables. Innovations show their positive effect on employment with a time lag and process innovations have higher effects than product innovations.     

Identifying the determinants of broadband adoption by diffusion stage in OECD countries

Governments worldwide actively promote broadband development, owing to its positive impact on economic growth. Although many studies have identified the determinants of broadband adoption, this study re-examines the determinants by applying Arellano–Bond GMM dynamic panel data estimation with more complete panel data for OECD countries. The estimation can not only closely capture the dynamics of broadband diffusion but also solve an endogeneity problem existing in the estimations of previous studies. The estimation results indicate that content is also a significant factor, in addition to previous broadband penetration and platform competition, as commonly identified in previous studies. This study further examines and compares determinants in different stages segmented by adopter categories proposed by Rogers. The results reveal different determinants in different stages. The key determinants are income, education, and content in the innovator and early adopter stage; platform competition and previous broadband penetration in the early majority stage; and broadband price in the late majority and laggard stage. Governments should thus devise and implement appropriate strategies for the major potential adopters in each stage instead of adopting a one-size-fits-all strategy. The results of this study provide a valuable reference for countries in early stages of broadband development or for those planning or reviewing their strategies.
