The article argues that there is another hybrid path to the retrenchment which combines certain features of unilateralism and social bargaining. In this path, governments seek for a kind of social bargaining with the core beneficiary groups and their representatives, but in a more fragile and conflict-ridden way than in the corporatist counterpart. Such a 'non-corporatist' social bargaining has been present in advanced European countries. However, existing studies have not paid due attention to it. The present study fills in this research gap by exploring a causal mechanism lying behind the under-researched reform path.
More specifically, the article argues that the 'non-corporatist' social bargaining occurs when weak governments promote benefit cuts that welfare insiders do not support. The hypothesis is examined against the recent cases of public pension reforms drawn from four Southern European countries: Italy, Spain, Portugal, and Greece. A total of 24 cases of pension cuts since the 1990s will be analyzed, relying on a combination of fuzzy-set Qualitative Comparative Analysis (fs-QCA) and selective case narratives.
