It has often been found difficult to generate a liquidity effect (i.e. a negative effect of monetary injections on the nominal interest rate) in the traditional "Ricardian" stochastic dynamic model with a single infinitely lived household. We show that moving to a non Ricardian environment where...

A most wellknown determinacy condition on interest rate rules is the "Taylor principle", which says that nominal interest rates should respond more than hundred percent to inflation. Unfortunately, notably because interest rates must be positive, the Taylor principle cannot be satisfied for all...

We construct in this paper a dynamic general equilibrium model which displays the central features of the IS-LM model, and notably an income multiplier greater than one, so that crowding out does not occur. It appears that the key to this result is the conjunction of two features of our model:...

Are prices less sticky when markets are more competitive? Our intuition would naturally lead us to give an affirmative answer to that question. But we first show that DSGE models with staggered price or wage contracts have actually the opposite and paradoxical property, namely that price...

This timely title gives a full account of the field, starting with the various general equilibrium traditions that ultimately led to this research area, and then describing the evolution of the models, with special emphasis on how they succeeded in representing features of dynamics that other...

Inflation is often given the central role in discussions of monetary policy. Is this emphasis warranted? We investigate this in a DSGE model and find: (1) One can implement the optimal interest rate policy using only employment as an instrument, (2) using inflation as an instrument would lead to...

The purpose of this article is to characterize optimal interest rate rules in the framework of a dynamic stochastic general equilibrium model, and notably to scrutinize the “Taylor principle”, according to which the nominal interest rate should respond more than one for one to inflation....
