Austerity is frequently associated with crisis-enabled spending cuts. What happens when the crisis is over? This article’s original contribution lies in its in-depth exploration of one mechanism that help explain austerity’s endurance post-crisis, when state elites face increased popular resistance and pressure to reinstate social spending. This mechanism calls attention to the role of economists in Central Budgeting Offices as agents of technocratization and de-politicization within social policy domains. These economists may institute an austere spending mode by changing social spending’s norms and instruments. To demonstrate economists’ role in mediating macroeconomic fiscal goals and social policy design over time, the article examines the development of child welfare policy in Israel before, during and in the aftermath of economic crisis. In this case, austerity attained hegemony when economists were able to delegitimize and shelve an ‘irresponsible’ social spending proposal – and in response to post-crisis demands for compensation – introduce an austere policy instrument to cap social spending during a period of social policy expansion. This analysis suggests that scholars regard relations between austerity and social spending as dialectical.
