The Southern Region Information Exchange Group-53 consists of 20 institutional members seeking a better understanding of the relationship between community infrastructure and economic development. This document contains four papers prepared for the group's working meeting in October 1990. "The Contribution of Four Lane Highway Investments to Employment Growth in Rural South Carolina 1970-89: Quasi-Experimentation," by M. S. Henry and others, concludes that new highways have attracted new employment opportunities to rural South Carolina. However, areas with higher growth rates, per capita incomes, and employment rates prior to highway construction benefitted most. "The Developmental Impacts of Transportational Investments," by T. G. Johnson, argues that hedonic land valuation is the only approach capable of comprehensively measuring the benefits of infrastructure investment. Using this approach within a geographic information system (GIS) is time consuming and expensive but can provide detailed projections of the location, timing, and magnitude of benefits from a great number of highway development alternatives. "GIS: A New Tool for Local Economic Development," by M. S. Henry and others, describes the use of GIS to test development policy hypotheses in South Carolina. GIS can maintain, retrieve, and manipulate spatial and nonspatial data about places, and may be used to construct hypothetical scenarios that could result from planning decisions. "Education: Linkages with Economic Development," by R. L. Clouser, reviews the research on economic development and education and finds few studies that demonstrate linkages between them. Possible research approaches are suggested. (SV)
