Presenting an overview of the economics of regional policies, this collection reprints work in the field, from 1964 to 1997. After making the case in favour of regional policies, the book explores the topic of economic disparities between regions including divergent economic growth, the effects of regional migration and wages, and the persisitence of disparities in unemployment. It then explores the different regional policy instruments that have been introduced in the United Kingdom and in the United States and Canada and examines their implications. A separate section is devoted to the particular case of the European Union. The final section offers an evaluation of regional policies and their effects on economic efficiency.
