Impact analysis of economic policy is a subject which is gaining in creasing interest in both theoretical and applied economic research. Two main reasons for the growing interest can be distinguished. First, the situation of the government's finances is making it more than ever necessary to assess critically the effects of the instruments used to pursue public policy goals. Secondly, because of the economic stagnation government will be increasingly appealed to for support. Impact analysis, however, is hampered by three major problems: methodological deficiencies, lack of econometric approaches which have been adapted to the specific conditions of this kind of analysis and data availability. The present book deals with these problems in the context of regional economic policy. However, the main findings are broadly applicable in various other fields. This book is primarily oriented towards those who have a practical interest. Therefore, attention is mostly paid to the practical aspects of the methodology and the measurements methods. Furthermore, the methodologi cal and econometric parts are supplemented by two extensive case studies. - Three people have contributed constructive criticisms and suggestions on some chapters of the book: Peter Nijkamp, Theo Dijkstra and Manfred Fischer. I am very grateful for their support. They, of course, share no blame for any deficiences in the present form of the book. I also gratefully acknowledge the assistance of Harry Barkema and Marja Schuring with the computations."

In September 1977 a 'Regional Science Symposium' was held at the Faculty of Economics of the University of Groningen in the Netherlands. Organized because of the recent establishment at the Faculty of Economics of a group that is engaged in teaching and research in the field of regional science, the aim of the symposium was to make university members more familiar with regional science and to introduce the newly created group to the national and international scene. Two separate topics were selected, of potential interest to both re searchers and policy-makers. The first, spatial inequalities and regional development, was chosen because of its central place in regional science. Authors from several disciplines were asked to approach this theme from a general, policy orientated point of view. This ensured the enlightenment of the various dimensions of spatial inequality and its implications for regional policy. The results have been collected in the volume Spatial Inequalities and Regional Development. The second theme focused on spatial statistical analysis. This branch of statistics is a relatively new one which receives growing attention among researchers in the field of applied regional science. The meeting on this topic concentrated on new results of research on the use of appro priate statistical and econometric methods for analyzing spatial data. The papers concerned have been collected into another volume, Explora tory and Explanatory Statistical Analysis of Spatial Data."
