The European Union is widely regarded as premised on an imbalance between market-making and market-correcting provisions, potentially weakening national welfare systems and the political legitimacy of the European project. However, a stronger role for the EU in social policy faces considerable difficulties. The Open Method of Coordination (OMC) represents a new governance approach to European social policy and was adopted in the late 1990s.
