The Common Agricultural Policy (CAP) can be fruitfully construed as an instance of European embedded liberalism, shaped by overlapping layers of domestic, European Union, and international policymaking. Such a conceptualization reveals the large role of domestic politics, even in an area like the CAP, where policy competences were early on extensively transferred to the supranational level. This in turn reflects the rather prominent role of national governments in the EU construction, compared with traditional federal polities. This role can be probed by analyzing two related scholarly agendas: an agenda devoted to the shaping of the CAP by member states (policy shaping); and an agenda devoted to the domestic impact of the CAP. Current policy challenges highlight our need to develop our understanding of: (1) the interaction between different types of CAP decisions at the EU level; (2) the domestic impact of the CAP; (3) and the experience of Central and Eastern European Countries (CEEC).
