The effects of quantitative easing policy, which looks like a “helicopter dropping” of money, are quite complex. Implemented following a major crisis induced by the deflation of bubbles on asset prices, this policy creates redistributive effects in favour of financial and banking...

Using a New-Keynesian model extended to include credit, money and reserve markets, we examine the dynamics of inflation and output gap under some monetary policy options adopted when the economy is hit by large negative real, financial and monetary shocks. Relaxing the assumption that market...

Some countries may face choice between targeting inflation independently and entering a monetary union that targets inflation. This paper shows that the choice of a country in favour of monetary union may be motivated by asymmetrical supply shocks. The demand shocks are neutralised under these...

In a two-period model with distortionay tax and public investment, we reexamine the interaction between monetary policy transparency and fiscal bias. We find that the optimal decisions of tax and public investment allow eliminating the effects of fiscal bias and hence neutralizing the impact of...

Cet article étudie la stabilité macroéconomique lorsque la Banque Centrale intègre dans sa règle du taux d'intérêt optimale les cours boursiers. Nous montrons que lorsque la Banque Centrale a une forte aversion pour l'inflation en attribuant un poids important à l'objectif de l'inflation...

We estimate monetary policy reaction functions with threshold effects for the Deutsche Bundesbank using a real-time data set. Estimates based on the deviation of inflation from the Bundesbank's inflation target as threshold variable suggest a switch to a stronger output gap response in the...

We use a Taylor rule with time-varying policy coefficients in combination with an unobserved components model for the output gap to estimate the uncertainty about future values of the Federal Funds Rate. The model makes it possible to separate ex-ante interest rate uncertainty into three...

We study how the inclusion of growth rates of monetary aggregates or changes in stock market indices affects the stabilization performance of optimal monetary policy rules when there is uncertainty about the structure of the economy. With a simulation model of the U.S. economy we show that the...

In this paper we examine the macroeconomic stability in a simple dynamic open economy model, in which monetary authorities adopt an flexible inflation-targeting regime in an environment with a liberalised capital account and flexible exchange rates. In this respect, inflation targeting is an...

Dans cet article, nous étudions l’efficacité de politiques économiques dans un cadre d’une petite économie ouverte où la relation entre le taux de change, le prix des actions et le niveau d’activité est soumise à des interactions entre l’effet de “pass-through” incomplet et...
