Economic Science and Practice seeks to bridge the gulf between economic theory and policy and overcome some of the problems created by the specialized nature of much economic research. A distinguished group of academic economists and experienced policymakers, from both Europe and the United States, sheds new light on the relation between theory and practice and reflects on the current state of economics. There is an ever present danger that modern economic theory is becoming too detached from the real world. In contrast to this concern there are those who argue that there is a risk of practitioners and policymakers relying on pre-scientific ideas or ideologies not tested against the latest scientific insights. This book will not only help to improve communication between scientists and policymakers, but will also show how it is possible to strengthen the scientific base of economic policy and improve the social relevance of economic research and education.

This insightful book focuses on the economic consequences of structural reform policies in the economies at the cutting edge of reform: Denmark, The Netherlands, New Zealand and Norway. The contributors examine policies aimed at improving the underlying path of growth, employment and saving-investment balances of the economy and apply state of the art methods to measure and model structural reforms. They examine the areas of competition policy, regulation of entry barriers, non-tariff trade barriers and employment protection rules as well as the quality of education and training, the efficiency of various public sector agencies and labour supply effects of care for children and the elderly. Special attention is paid to two 'success stories': New Zealand's 'Kiwi-model' and the Dutch 'Polder-model'. The book provides a welcome addition to the scarce evidence on both the costs and the benefits of structural reform and identifies the policy problems and the analytical issues at stake. This book will be indispensable to policymakers and academics with an interest in structural reform and macroeconomic policy.

Over the last decade or so, applied general equilibrium models have rapidly become a major tool for policy advice on issues regarding allocation and efficiency, most notably taxes and tariffs. This reflects the power of the general equilibrium approach to allocative questions and the capability of today's applied models to come up with realistic answers. However, it by no means implies that the theoretical, practical and empirical problems faced by researchers in applied modelling have all been solved in a satisfactory way. Rather, a promising field of research has been opened up, inviting theorists and practitioners to further explore and exploit its potential. The state of the art in applied general equilibrium modelling is reflected in this volume. The introductory Chapter (Part I) evaluates the use of economic modelling to address policy questions, and discusses the advantages and disadvantages of applied general equilibrium models. Three substantive issues are dealt with in Chapters 2-8: Tax Reform and Capital (Part II), Intertemporal Aspects and Expectations (Part III), and Taxes and the Labour Market (Part IV). While all parts contain results relevant for economic policy, it is clear that theory and applications for these areas are in different stages of development. We hope that this book will bring inspiration, insight and information to researchers, students and policy advisors.
