A core, but so far untested, proposition of the new politics perspective, originally introduced by Paul Pierson, is that welfare state cutbacks will be implemented using so-called 'invisible' policy instruments, e.g. a change in indexation rules. Expansion should, by implication, mainly happen using 'visible' policy instruments, e.g. a change in nominal benefits. We have coded 1,030 legislative reforms of old-age pensions and unemployment protection in Britain, Denmark, Finland, and Germany from 1974 to 2014. With this unique data at hand, we find substantial support for this crucial new politics proposition.
