This article examines with empirical evidence the social protection measures implemented in response to the COVID-19 pandemic in ten welfare states in the Global North. We analysed the potential similarities and differences in responses by welfare regimes. The comparative study was conducted with data from 169 measures, collected from domestic sources as well as from COVID-19 response databases and reports. In qualitative terms, we redeveloped Hall’s theory on the distinction between first-, second- and third-order changes. In accordance with the path-dependence thesis, we show systematically that the majority of the studied changes (91%) relied on a pre-pandemic tool demonstrating flexibility within social security systems. The relative share of completely new instruments was notable but modest (9%). Thematically, the social protection measures converged beyond traditional welfare regimes, particularly among the European welfare states. Somewhat surprisingly, the changes to social security systems related not just to emergency aid to mitigate traditional risks but, to a greater extent, also to prevent new risks from being actualised.
