The aim of this volume is to consider intertemporal and strategic issues in the formulation of economic policy so that dynamic game methodology is appropriate. When changes in economic policy are evaluated the reactions and expectations of other economic agents cannot be ignored, and in a dynamic setting issues like time inconsistency, subgame perfectness, reputation and information become important.The papers contained in this volume are the revised versions of those presented at a conference held in 1988 at Tilburg University, The Netherlands. They include methodological contributions and strategic analyses of macroeconomic policy, resource economics, international policy coordination and the arms race.
