The article explores the paradox of European integration, where progress is limited but resilience persists. It argues that this paradox is due to the "joint-decision trap," a phenomenon observed in both German federalism and the European Community. In both systems, member governments directly participate in central decisions and require unanimous agreement, leading to sub-optimal policy outcomes unless a "problem-solving" approach is used. However, a "bargaining" style of decision-making has dominated, resulting in inefficiencies and frustrations without disintegration. The article compares the institutional structures of German federalism and the European Community, noting similarities in their decision-making processes. In Germany, the federal government and Länder (states) share responsibilities, with decisions requiring consensus. Similarly, in the European Community, decisions often require unanimous agreement, leading to similar inefficiencies. The article highlights how these structures have led to a lack of progress in European integration, despite the Community's resilience. In Germany, joint decision-making in areas like education and regional policy has led to inefficiencies, inflexibility, and a lack of democratic control. The article argues that the "joint-decision trap" is a result of the institutional conditions that require unanimous agreement, leading to sub-optimal outcomes. This is evident in the European Community, where the Common Agricultural Policy (CAP) has been criticized for its inefficiencies and high costs, despite its intended goals. The article concludes that the European Community's resilience is due to the persistence of these institutional structures, even though they have led to frustration and inefficiencies. The CAP, despite its flaws, remains a significant part of the Community's structure, and its future is uncertain. The article suggests that the "joint-decision trap" is a systemic issue that will continue to affect European integration, even as the Community seeks to adapt and improve.The article explores the paradox of European integration, where progress is limited but resilience persists.
