Austerity versus stimulus: the polarizing effect of fiscal policy

mcmanus, richard;

Through constructing a new Keynesian DSGE model with heterogeneous agents, this article investigates both the aggregate and distributional consequences of fiscal policy. Polarized preferences over the conduct of fiscal policy emerge between those agents who participate in credit markets and those who do not. Exogenous shocks impact the two types of agent differently, and as a result, fiscal policy responses to
these shocks produce minimal aggregate welfare effects as the gains of one agent are matched by the losses of another. There is therefore a normative justification for counter-cyclical fiscal policy, but on redistributive rather than stabilization grounds.
