Abstract

Consumption externalities Determinacy Monetary policy New-Keynesian model Stock prices
We study interest rate rules responding to stock prices in a sticky-price sticky-wage New-Keynesian framework subject to consumption externalities. For given wage rigidity, such rules are beneficial to equilibrium determinacy if households’ preferences feature sufficiently strong keeping-up-with-the-Joneses externalities. •Presents a New-Keynesian model with sticky wages and consumption externalities.•Studies determinacy properties of Taylor rules responding to stock prices.•Keeping-up-with-the-Joneses (KUJ) externalities help making dividends pro-cyclical.•Responding to stock prices improves determinacy if the KUJ externalities are sufficiently strong.
