In a model with imperfect money, credit and reserve markets, we examine if an inflation-targeting central bank using the funds rate operating procedure to indirectly control market interest rates also needs a monetary aggregate as policy instrument. We show that if private agents use information...

Within a New Keynesian model subject to misspecification, we examine the quadratic contracts in a delegation framework where government and private agents are uncertain about central bank preferences for model robustness. We show that, in the case of complete transparency, the optimal penalty is...

Recent financial crises and central banks’ interventions to ensure liquidity on the monetary markets around the world have shown that using interest rate as instrument of monetary policy can be insufficient. Using an aggregate dynamic macro-economic model, we study how to combine inflation...

Using a macroeconomic model with asset prices, we analyze how optimal monetary policy, and macroeconomic dynamics and performance are affected by the central bank’s desire to be robust against model misspecifications. Considering the worst-case model, we show that an increase in the central...

Using a New Keynesian small open economy model, we examine the effects of central bank transparency on inflation persistence. We have found that more opacity could reinforce the effect of persistent shocks on the level and variability of endogenous variables if the difference between the...

Cet article étudie les implications, en termes de stabilité économique, de la relation entre le degré d’indépendance de la Banque centrale et le degré de transparence (ou d’opacité) de la politique monétaire dans un modèle qui tient explicitement compte des marchés financiers et...

Using a simple macro-economic model, this study shows how a two-pillar monetary strategy as practiced by the European central bank (ECB) can be conceived to guarantee dynamic macro-economic stability and the credibility of monetary policy. This strategy can be interpreted as a combination of...

This paper examines a model of financial and exchange crises with balance-sheet effects by explicitly taking account of wealth accumulation and external equilibrium condition. We have found that, in a general equilibrium analysis, there are two stationary equilibria. Since foreign debt is always...

In this paper, we examine the link between political transparency of a common central bank (CCB) and decentralized supply-side fiscal policies in a monetary union. We find that the opacity of a conservative CCB has a restrictive effect on national fiscal policies since each government...

The mainstream inflation-targeting literature makes the strong assumption that the central bank can exactly target the interest rate which affects investment and consumption decisions and hence the money supply plays no role in the monetary policy strategy. This assumption is equivalent to...
