With particular emphasis on the role and effectiveness of public policy, this volume focuses on the what can be learned from a rigorous comparison of the patterns and processes of urban concentrations of residents and employment in western Europe and the United States? A wide range of methodological techniques are used-economic theory, econometrics, general economic analysis, regional science, and institutional historical analysis-with full recognition of the political, social, and economic factors underlying location decisions. This volume has a breadth of coverage that should make it a standard reference. Contributing authors include "Anthony Downs, Mark Alan Hughes, Dick Netzer, Lanfranco Senn and Gianluigi Gorla, Edwin S. Mills," and "Paul Cheshire."
