Constructing the divide: Spatial disparities in broadband access

As residential broadband options such as cable and xDSL grow in popularity, broadband providers continue to roll out service in select market areas. However, due to technological limitations, some locations qualify for xDSL broadband service while others do not. The purpose of this article is to examine the impact of local geography on broadband (xDSL) network access. This type of micro-geographic analysis is important in two ways. First, a detailed analysis at the local level can reveal the spatial disparities in infrastructure access. Second, because broadband access is quickly emerging as the technology of choice for both small businesses and households, it is important to consider which locations will have opportunities for these connections and which locations will not. Utilising an integer programming model, the maximal covering location problem, and a geographic information system, xDSL broadband access is evaluated in Columbus, Ohio. Results indicate that many suburban areas can be left without adequate service. Received: 6 October 2000 / Accepted: 18 June 2001     

Factors influencing the temporal diffusion of broadband adoption: evidence from Oklahoma

This paper examines the shifting influence of household characteristics and telecommunications infrastructure on the residential broadband adoption decision for Oklahoma residents between 2003 and 2006. In particular, the spread of wired telecommunications infrastructure (namely cable Internet and Digital Subscriber Lines (DSL)) is examined, along with the effect that this diffusion has had on broadband access rates. The data indicates that the gap in broadband access rates between rural and urban areas has remained relatively constant over this period despite increased levels of cable and DSL throughout the state. In addition, an inter-temporal decomposition shows that the increasing levels of infrastructure are not the dominant cause of higher broadband rates over time. Instead, shifting returns to specific characteristics (namely income) are found to be the primary contributors.     

Inequities in the broadband revolution

Residential broadband options such as cable and digital subscriber lines are growing in popularity. However, evidence suggests that urban areas are receiving the majority of infrastructure investment, thereby leaving many rural locations with few options for broadband access. With access to telecommunication infrastructure becoming an increasingly important component to local economic development, issues of infrastructure equity are significant. This paper explores telecommunication equity and its effect on economic development by addressing the impact of geography on infrastructure investment and growth. A comprehensive database of broadband service providers and data from the Ecom-Ohio project (http://www.ecom-ohio.org), are used to explore broadband access options in the state of Ohio by examining the characteristics of market demand that are driving cable and digital subscriber line infrastructure investment. In addition, this paper develops an explanatory framework for identifying key market characteristics indicative of demand for residential broadband services through the use of statistical models and a geographic information system. Results suggest that income, education, age, location, and competition from alternative broadband platforms influence digital subscriber line infrastructure investment.
