Parties
This chapter focuses attention on short-term and long-term impacts of political parties on social policy in advanced democracies. According to a wide variety of both comparative research and in-depth country studies, partisan effects have influenced the structure and expansion of the welfare state in the post-Second World War period to a large extent. Particularly strong have been these effects in the ‘Golden Age’ of the welfare state in the 1960s, 1970s, and in some countries also in the 1980s—mainly due to policy choices of leftist and Christian democratic parties. More mixed has been the explanatory power of partisan theory after the ‘Golden Age’. In view of critical circumstances, such as a major fiscal crisis of the state and the pressure generated by demographic ageing, but also due to massive changes in their social constituencies, a considerable number of pro-welfare state parties accepted recalibration and cutbacks in social policy in order to consolidate budgets.
