‘Hans-Peter Brunner has produced here a very thoughtful piece of scholarship. This important book is genuinely innovative and very well executed. It addresses a very significant problem - how the integration and inter-linkage of national markets through regional cooperation and integration adds to productivity growth. The book goes on to define a meaningful theoretical framework, describes relevant regional experiences, and then presents a road map for cluster development. As such, it will be of value to academics, practitioners and policy makers alike.’
