The State and its Welfare State: How do Welfare State Changes Affect the Make‐up of the Nation State?

With respect to changes in the welfare states of OECD countries, scholars most of the time are looking for common trends; that is, they look for similar movements in different states, such as welfare state retrenchment, recalibration, etc. As we show in this article, data on welfare state spending and financing do not, however, support such stark tendencies like retrenchment. We therefore suggest looking for corridor effects rather than level effects, i.e. analysing changes in the dispersion of welfare state regimes rather than shifts in the mean values. Our analysis suggests that convergence, i.e. decreasing diversity among states in spending, financing and regulation patterns, may have been the most important pattern of welfare state change in the last three decades – a pattern easily overlooked in past and current research. Convergence of welfare state regimes also affects our views on the modern nation state itself since the varieties of welfare capitalism in the twentieth century are themselves an expression of the sovereignty and autonomy of the nation state. If nation states are forced to surrender national particularities, to mellow their characteristic differences and to move incrementally towards a one‐size‐fits‐all common model via ‘shrinking corridors’, such a blurring of welfare regimes, such a beclouding of difference, should also be regarded as a significant change taking place in the centre of the Western nation state's make‐up.
