Monetary Policy and Bubbles in New Keynesian Model with Overlapping Generations

Author

Listed:
  • Galí, Jordi

Abstract

I analyze an extension of the New Keynesian model that features overlapping generations of finitely-lived agents and (stochastic) transitions to inactivity. In contrast with the standard model, the proposed framework allows for the existence of rational expectations equilibria with asset price bubbles. I study the conditions under which bubble-driven fluctuations may emerge and the type of monetary policy rules that may prevent them. I conclude by discussing some of the model's welfare implications.
