Institutional arrangements constitute the "rules of the game" for any civil and political society. To understand urban politics and policy making, including issues dealing with economic development, zoning, constituency representation, government borrowing, and service contract decisions, discovering institutional regularities is key. To achieve this the authors combine older institutional approaches emphasizing formal structure and governance organizations with newer approaches and transaction cost theory. Institutional Constraints and Policy Choice contends that institutional arrangements both shape and are shaped by human behavior, and when combined with contextual factors and the uncertainty associated with leadership turnover provide the basis of understanding how decisions are made at the level of local government.
