We construct an endogenous growth model with new Keynesian-type sticky prices and wages. In this model, monetary policy affects long-run output growth. We characterize the optimal operational monetary policy rule in this economy. We find that even though stabilization of output growth increases...

I estimate DSGE models with recurring regime changes in monetary policy (inflation target and reaction coefficients), technology (growth rate and volatility), and/or nominal price rigidities. In the models, agents are assumed to know deep parameter values but make probabilistic inference...

Models dealing with monetary policy are generally based on microfoundations that characterize the behaviour of representative agents (households and firms). To explain the representative consumer behaviour, it is generally assumed a utility function in which the intertemporal elasticity of...

The current financial crisis followed the “great moderation,” according to which the world’s central banks had gotten so good at countercyclical policy that the business cycle no longer existed. As more and more economists and media people became convinced that the risk of recessions had...

The standard new Keynesian monetary policy problem is, in its original presentation, a linear model. As a result, only three possibilities are admissible in terms of long term dynamics: the equilibrium may be a stable node, an unstable node or a saddle point. Fixed point stability (a stable...

In late 2008 and early 2009, there has been a serious deterioration in the economic outlook of political leaders, the media and many economic analysts. Comparisons of recent performance and the outlook have degenerated into comparisons with the Great Depression of the 1930s, suggesting that the...

A recent study shows that equilibrium indeterminacy arises if monetary policy responds to asset prices, especially share prices, in a sticky-price economy. We show that equilibrium indeterminacy never arises if the working capital of firms is subject to their asset values by financial frictions.

In most manufacturing industries output is adjusted in a lumpy way along three margins: shiftwork, weekend work, and closing a plant temporarily down. We incorporate such decisions into a dynamic general equilibrium model and study: (i) if such micro-level nonconvexities magnify business cycles;...

This article rejects the linkages in proposals that the Federal Reserve Bank (Fed) target equity prices. The real federal funds rate (RFF) and stock prices (SP) are uncorrelated; causality tests show a positive effect of SP on RFF and a negative effect of SP on RFF. These results occur as part of...
