This paper uses a model of boundedly rational learning to account for the observations of recurrent hyperinflations in the last decade. We study a standard monetary model, where the full rational expectations assumption is replaced by a formal definition of quasi-rational learning. The model...

The paper considers the macroeconomic transmission of demand and supply shocks in an open economy under alternative assumptions on whether the zero interest floor (ZIF) is binding. It uses a two-country general-equilibrium simulation model calibrated to the Japanese economy vis-à-vis the rest...

We calibrate a standard New Keynesian model with three alternative representations of monetary policy- an optimal timeless rule, a Taylor rule and another with interest rate smoothing- with the aim of testing which if any can match the data according to the method of indirect inference. We find...

In this paper we estimate a New-Keynesian DSGE model with heterogeneity in price and wage setting behavior. In a recent study, Coibion and Gorodnichenko (2011) develop a DSGE model, in which firms follow four different types of price setting schemes: sticky prices, sticky information, rule of...

We show that deviations from long-run stability of product prices are optimal in the presence of endogenous producer entry and product variety in a sticky-price model with monopolistic competition in which price stability would be optimal in the absence of entry. Specifically, a long-run...

This paper argues that limited asset market participation is crucial in explaining U.S. macroeconomic performance and monetary policy before the 1980s, and their changes thereafter. We develop an otherwise standard sticky-price DSGE model, whereby at low enough asset market participation,...

Recent empirical literature documents that unexpected changes in the nominal interest rates have a significant effect on stock prices: a 25-basis point increase in the Fed funds rate is associated with an immediate decrease in broad stock indices that may range from 0.5 to 2.3 percent, followed...

Since Bernanke, Gertler and Watson (1997), a common view in the literature has been that systematic monetary policy responses to the inflation triggered by oil price shocks are an important source of aggregate fluctuations in the U.S. economy. We show that there is no evidence of systematic...

This paper shows that absent a commitment technology, central banks can nevertheless achieve the (timeless-)optimal commitment equilibrium if they are delegated with an objective function that is different from the societal one. In a prototypical forward-looking New Keynesian model, I develop a...

The New-Keynesian Taylor-Rule model of inflation determination with no role for money is incomplete. As Cochrane (2007a, b) argues, it has no credible mechanism for ruling out bubbles (or deal with the non-uniqueness problem that arises when the Taylor principle is violated) and as a result...
