Trade, Networks, and Hierarchies: Modeling Regional and Interregional Economies, New York, NY, (2002)

This chapter presents a new method for identifying key sectors in communities, where sectors are defined broadly to include churches, clubs, associations, and public institutions as well as different types of businesses and industries. We describe and apply new ways to (1) quantify the local community structure, (2) describe the various roles, (3) identify the keystone sectors in a community. We adapt methods of graph theory and social network analysis to the analysis of a local econmic system.
