We estimate the response of stock prices to monetary policy shocks using a time-varying coefficients VAR. Our evidence points to protracted episodes in which stock prices end up increasing persistently in response to an exogenous tightening of monetary policy. That response is at odds with the...

I examine the impact of alternative monetary policy rules on a rational asset price bubble, through the lens of an OLG model with nominal rigidities. A systematic increase in interest rates in response to a growing bubble is shown to enhance the fluctuations in the latter, through its positive...

I examine the impact of alternative monetary policy rules on a rational asset price bubble, through the lens of an overlapping generations model with nominal rigidities. A systematic increase in interest rates in response to a growing bubble is shown to enhance the fluctuations in the latter,...

Much recent research has focused on the development and analysis of extensions of the New Keynesianframework that model labor market frictions and unemployment explicitly. The present paper describessome of the essential ingredients and properties of those models, and their implications for...

I discuss several lessons regarding the design and conduct of monetary policy that have emerged out of the New Keynesian research program. Those lessons include the benefits of price stability, the gains from commitment about future policies, the importance of natural variables as benchmarks for...

We study how changes in the value of the steady-state real interest rate affect the optimal inflation target, both in the U.S. and the euro area, using an estimated New Keynesian DSGE model that incorporates the zero (or effective) lower bound on the nominal interest rate. We find that this...

We address this question using an estimated New Keynesian DSGE model of the Euro Areawith trend inflation, imperfect indexation, and a lower bound on the nominal interest rate. Inthis setup, a decrease in the steady-state real interest rate, r*, increases the probability ofhitting the lower...

We address the question in this paper's title using an estimated New Keynesian DSGE model of the euro area with trend inflation, imperfect indexation, and a lower bound on the nominal interest rate. In this setup, a decrease in the steady-state real interest rate, r*, increases the probability...

We analyze the welfare impact of greater wage flexibility while taking into account explicitly the existence of the zero lower bound (ZLB) constraint on the nominal interest rate. We show that the ZLB constraint generally amplifies the adverse effects of greater wage flexibility on welfare when...
