Abstract

We reconsider the issue of equilibrium determinacy under the limited asset market participation hypothesis in a medium-scale model which accounts for external consumption habits. This allows to characterize concern for relative consumption in the preferences of agents which are heterogeneous in their wealth holdings. We find that external habits and consumption inequality have mutually reinforcing adverse e¤ects on determinacy. We therefore uncover a causality link between long-run inequality and macroeconomic volatility in a New-Keynesian DSGE model. In our framework, redistributive polices targeting consumption inequality have beneficial implications for macroeconomic stability..
