Discussion of welfare regimes and welfare state ideal types continues to dominate comparative social policy analysis, but the focus of the debate has expanded considerably since the publication of Esping-Andersen's (1990) groundbreaking The Three Worlds of Welfare Capitalism. Shifts in this debate have been prompted by a mixture of theoretical and empirical concerns raised by comparative social policy scholars, but they have also resulted from a more general internationalisation of social policy research agendas within the academy too. In particular, there has been a strong desire to expand the scope of the debate to encompass nations and regions not included in Esping-Andersen's initial study of just eighteen high income OECD states.
