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....

An important recent advancement in macroeconomics is the development of dynamic stochastic general equilibrium (DSGE) macromodels. The use of DSGE models to study monetary policy, however, has led to paradoxical and puzzling results on a number of central monetary issues including price...

The Taylor principle is quite usually considered as a central condition for price determinacy. Recently, however, this has been questioned on several grounds, notably because (i ) this condition is a condition for local determinacy, not global determinacy (ii ) it has been derived in...

[eng] Classical and Keynesian Features in Macroeconomic Models of Imperfect Competition For more than fifty years now the two main (and competing) paradigms in macroeconomics have been the classical and Keynesian ones. Since about twenty five years a new paradigm, imperfect competition...

It is often believed that governments should either abstain from leading activist policies, or if they lead such policies, that these policies should somehow be “stabilizing”, in the sense of reducing the volatilities of some endogenous variables. We construct a model with explicit...

This paper links the two fields of “development traps” and “brain drain”. We construct a model which integrates endogenous international migration into a simple growth model. As a result the dynamics of the economy can feature some underdevelopment traps: an economy starting with a low...

The fiscal theory of the price level says that the price level can be made determinate if the government uses fiscal policies such that government liabilities explode unless the price in the first period is at the "right" level. The policy implications are disturbing, as they call for rather...

The Taylor principle is quite usually considered as a central condition for price determinacy. Recently, however, this has been questioned on several grounds, notably because (i) this condition is a condition for local determinacy, not global determinacy (ii) it has been derived in "Ricardian"...
