The study of metropolitan political economies in the United States has provided much of the intellectual inspiration for the research of the Workshop in Political Theory and Policy Analysis at Indiana University. The readings collected in Polycentricity and Local Public Economies present an overview of the results of this research program on police services and metropolitan governance as well as enduring lessons for institutional analysis and public policy. Polycentricity and Local Public Economies presents both explorations of broad general concepts and specific empirical analyses. The many interactions between the two modes of analysis provide valuable insights for the reader. Readings in the first section cover basic theoretical concepts and analytical distinctions that apply to the study of institutions generally. The second section includes conceptual pieces specifically addressed to the nature of governance in metropolitan areas, while section three reports on a series of empirical studies of police performance. Section four again broadens the focus to highlight the overall organization of local public economies. The final section discusses conceptual advances that have continuing relevance for research and policy debates. Contributors include William Blomquist, Kathryn Firmin-Sellers, Roy Gardner, Dele Olowu, Elinor Ostrom, Vincent Ostrom, Amos Sawyer, Edella Schlager, Shui Yan Tang, Wai Fung Lam, and James S. Wunsch.
