To remain vital and effective, welfare states must adapt to changing social, political, and cultural circumstances. For several decades the world’s advanced nations have been transitioning from industrial to post-industrial production. Welfare states have been faced with new kinds of social risk, new forms of economic insecurity, and new difficulties dealing with the older problems for which they were designed. Adjusting to these upheavals is a challenge for welfare state governance everywhere and, although national responses vary, the evidence suggests that a new generation of policies is being developed: ‘Welfare State 3.0’. ‘Post-industrial transitions: towards WS 3.0’ discusses the socio-economic transformations and adaptive reforms that are currently unfolding.
