Trading information is an essential aspect of the negotiations that underpin planning practice across the globe. In this book, Alex Lord uses information economics to outline a way of thinking about these negotiations that places the strategies that actors in the planning game use at the heart of the debate. Dialogue between economics and planning theorists has been, until now, rare. Lord argues that information economics' tool kit, game theory including well-known examples such as the Prisoners' Dilemma, the Stag Hunt game and Follow the Leader - offers an analytical framework ideally suited to unpacking planning processes. This use of game theory to understand how counterparties interact draws together two distinct bodies of literature: firstly the mainstream economics treatment of games in abstract form and, secondly, accounts of actual bargaining in planning practice from a host of international empirical studies. Providing a novel alternative to existing theories of planning, The Planning Gameprovides an explanation of how agencies interact in shaping the trajectory of development through the application of game theory to planning practice.
