Description:"Empowering Metropolitan Regions through New Forms of Cooperation" analyses the development of cross-border and cross-sector partnerships in various European cities and regions. It provides insight into the factors of failure and success in relation to the coalition-forming process by comparing various attempts at this in European regions. Over the course of eight case studies the following questions are addressed: What forms of metropolitan and/or regional partnerships can be found? What are the motives for establishing such partnerships? What factors contribute to or obstruct cooperation on the metropolitan level? How is performance of partnership models to be measured? How are the successes and failures of these attempts to be explained?The comparative analysis of these attempts to establish cooperation between municipalities sheds light on the importance of a regional approach to governance in dealing with challenges that cross the borders of borders.
