We determine optimal monetary policy under commitment in a forwardlooking New Keynesian model when nominal interest rates are bounded below by zero. The lower bound represents an occasionally binding constraint that causes the model and optimal policy to be nonlinear. A calibration to the U.S....

We determine optimal discretionary monetary policy in a New-Keynesian model when nominal interest rates are bounded below by zero. Nominal interest rates should be lowered faster in response to adverse shocks than in the case without bound. Such ‘preemptive easing’ is optimal because...

We study optimal nominal demand policy in an economy with monopolistic competition and flexible prices when firms have imperfect common knowledge about the shocks hitting the economy. Parametrizing firms' information imperfections by a (Shannon) capacity parameter that constrains the amount of...

We estimate a forward-looking New Keynesian Phillips Curve (NKPC) for the U.S. using data from the Survey of Professional Forecasters as proxy for expected inflation. We obtain significant and plausible estimates for the structural parameters of the NKPC (the discount factor and the share of...

This paper highlights the analysis of the term structure of interest rate within a full DSGE model. Our goal consists in setting up a full model including the feed-back from the economy to the term structure and vice-versa. Contrary to existing models of the term structure (TS, henceforth) (for...

In this paper, I consider a simple model in which agents learn about the inflation target of a central bank over time by observing the policy instrument or inflation outcomes. Measuring credibility as the distance between the perceived target and the actual target, an increase in credibility is...

In this paper, I estimate an open economy DSGE model for the Taiwanese economy. The model features multiple sources of real and nominal rigidities, including price and wage stickiness, investment and bond adjustment costs, as well as incomplete pass-through of exchange rates. Contrary to the...
