As European countries become more interdependent, the institutional provision of common goods increasingly must be organized across national boundaries, across levels of government, and across sectors. In addition, public and private decision-makers must collaborate. These new paradigms call for new institutional and instrumental arrangements that challenge existing modes of governance. This volume addresses important questions about the governance of common goods and the crucial role of private actors. The authors explore how collective action problems can be solved institutionally when countries are faced with cross-boundary problems and a simultaneous lack of hierarchical guidance.
