Economic Theory, academic policy analysis and public policy design are becoming more interdependent. Hence, the demands for close interactions between the policy community and the research community have been rising significantly. This book assesses how recent economic thinking has advanced under these influences. Furthermore, it evaluates the important contribution economics can add to the design and evaluation of public policy, now more than ever before. The study is of interest to policy makers, policy analysts, researchers and students of economics at all levels. The authors, which include many of Germany's most eminent economists, draw on their wide experience in research and consultancy to present a coherent view of where European economic theory stands today and how it can play a role in the management of the economy of the new millennium.
