In the conventional literature of comparative political economy, fiscal austerity has been considered as a policy pursued typically by governments that adhere to conservative economic ideologies. In recent decades, however, especially after the Eurozone Crisis in 2009, not only right-wing governments but leftist and left-center coalition governments have also carried out austerity policies. While it is generally documented that fiscal austerity spurs citizens' grievances and leads to anti-government movements, whether and how the varying partisanship of the incumbent government affects the pattern of such movements is yet to be known. In this paper, I argue that austerity, when adopted by left-dominant governments, adds a "premium" to public grievances because, as the classic partisan theory posits (Hibbs 1977;Alesina 1987;Garrett and Lange 1989), citizens' prior beliefs about policy consequences are asymmetrical such that they have fewer expectations of austerity when the left-wing parties are in power. Accordingly, I hypothesize that austerity led by the leftist governments results in a higher likelihood of anti-government movements than that led by the right-dominant government. I support this hypothesis by analyzing panel data covering up to 37 developed countries between 1973 and 2015.
