Abstract

This paper develops a model with discontinuous asset market participation, in which all agents are infinitely-lived and non-Ricardian, and where heterogeneity among market participants implies financial-wealth effects on aggregate consumption. Derivation of a welfare-based loss function shows that financial stability arises as an additional and independent target, besides infl ation and output stability. Evaluation of optimal policy under discretion and commitment reveals that price stability may no longer be optimal, even absent inefficient supply shocks: some fluctuations in output and infl ation are optimal as long as they reduce financial instability. Ignoring the heterogeneity among market participants in this economy may lead monetary policy to induce substantially higher welfare losses.
