Abstract

This paper investigates the effects of monetary policy in presence of heterogeneous consumers. We study the effectiveness (quantitative effects) of monetary policy and equilibrium determinacy properties of a New Keynesian DSGE model where a fraction of households cannot smooth consumption. We show that two-demand regimes can emerge (according to the “slope” of IS curve) and that the main unconventional results, stressed by recent literature, only hold in the unconventional case of an IS curve positively sloped.
