TL;DR: A conceptual framework for addressing infrastructure interdependencies is presented that could serve as the basis for further understanding and scholarship in this important area and is used to explore the challenges and complexities of interdependency.
Abstract: The notion that our nation's critical infrastructures are highly interconnected and mutually dependent in complex ways, both physically and through a host of information and communications technologies (so-called "cyberbased systems"), is more than an abstract, theoretical concept. As shown by the 1998 failure of the Galaxy 4 telecommunications satellite, the prolonged power crisis in California, and many other recent infrastructure disruptions, what happens to one infrastructure can directly and indirectly affect other infrastructures, impact large geographic regions and send ripples throughout the national a global economy. This article presents a conceptual framework for addressing infrastructure interdependencies that could serve as the basis for further understanding and scholarship in this important area. We use this framework to explore the challenges and complexities of interdependency. We set the stage for this discussion by explicitly defining the terms infrastructure, infrastructure dependencies, and infrastructure interdependencies and introducing the fundamental concept of infrastructures as complex adaptive systems. We then focus on the interrelated factors and system conditions that collectively define the six dimensions. Finally, we discuss some of the research challenges involved in developing, applying, and validating modeling and simulation methodologies and tools for infrastructure interdependency analysis.

Abstract: This paper investigates how telecommunications infrastructure affects economic growth. This issue is important and has received considerable attention in the popular press concerning the creation of the 'information superhighway' and its potential impacts on the economy. We use evidence from 21 OECD countries over a twenty-year period to examine the impacts that telecommunications developments may have had. We estimate a structural model, which endogenizes telecommunication investment by specifying a micro-model of supply and demand for telecommunication investments. The micro-model is then jointly estimated with the macro-growth equation. After controlling for country-specific fixed effects, we find evidence of a significant positive causal link, especially when a critical mass of telecommunications infrastructure is present. Interestingly, the critical mass appears to be at a level of telecommunications infrastructure that is near universal service.

Abstract: World development report 1994, the seventeenth in this annual series, examines the link between infrastructure and development and explores ways in which developing countries can improve both the provision and the quality of infrastructure services. In recent decades, developing countries have made substantial investments in infrastructure, achieving dramatic gains for households and producers by expanding their access to services such as safe water, sanitation, electric power, telecommunications, and transport. Even more infrastructure investment and expansion are needed in order to extend the reach of services especially to people living in rural areas and to the poor. But as this report shows, the quantity of investment cannot be the exclusive focus of policy. Improving the quality of infrastructure service also is vital. Both quantity and quality improvements are essential to modernize and diversify production, help countries compete internationally, and accommodate rapid urbanization. The report identifies the basic cause of poor past performance as inadequate institutional incentives for improving the provision of infrastructure. To promote more efficient and responsive service delivery, incentives need to be changed through commercial management, competition, and user involvement. Several trends are helping to improve the performance of infrastructure. First, innovation in technology and in the regulatory management of markets makes more diversity possible in the supply of services. Second, an evaluation of the role of government is leading to a shift from direct government provision of services to increasing private sector provision and recent experience in many countries with public-private partnerships is highlighting new ways to increase efficiency and expand services. Third, increased concern about social and environmental sustainability has heightened public interest in infrastructure design and performance. This report includes the World development indicators, which offer selected social and economic statistics for 132 countries.

Abstract: The empirical evidence that links political institutions to economic outcomes has grown dramatically in recent years. However, virtually all of this analysis is undertaken using data from the past three decades. This paper extends this empirical framework by performing a two-century long historical analysis of the determinants of infrastructure investment in a panel of over 100 countries. The results demonstrate that political environments that limit the feasibility of policy change are an important determinant of investment in infrastructure. Copyright 2002, Oxford University Press.

Abstract: It is widely argued that a country’s economic performance over time is determined to a great extent by its political, institutional and legal environment. We refer to these institutions and policies as the governance infrastructure of a country. We utilize newly developed indices to examine the effects of governance infrastructure on both foreign direct investment (FDI) inflows and outflows for a broad sample of developed and developing countries over 1995–97. In addition, we examine the role of other forms of infrastructure including human capital and the environment. The results clearly indicate that governance infrastructure is an important determinant of both FDI inflows and outflows. Investments in governance infrastructure not only attract capital, but also create the conditions under which domestic multinational corporations emerge and invest abroad. It would appear that investments in governance infrastructure are subject to diminishing returns, so that the benefits, in terms of inflows, are most pronounced for smaller and developing economies.
