This article investigates the dynamic implications of Krugman's (1999) model of financial crises with balance-sheet effects, which has a considerable impact on the literature of international financial crisis. Considering explicitly the wealth-accumulation constraint and the external equilibrium...

In this paper, using an IS-LM model with reserve market, we examine weather the operating procedure actually adopted by many central banks in the world, i.e. targeting directly short run interest rates and hence indirectly market interest rates, is more efficient in stabilizing output than a...

In a model with imperfect money, credit and reserve markets, we examine if an inflation-targeting central bank applying 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...

We introduce Large Scale Asset Purchases (LSAPs) in a New-Keynesian DSGE model that features distinct mortgage and corporate loan markets. We show that following a significant disruption of financial intermediation, central-bank purchases of mortgage-backed securities (MBS) are less effective at...

This paper extends the results of Kobayashi (2003) and Ciccarone and Marchetti (2009) by considering the optimal choice of central bank conservativeness. It is shown that the government can choose a sufficiently populist but opaque central banker so that higher multiplicative uncertainty...

In this paper, we study how the interactions between central bank transparency and fiscal policy affect macroeconomic performance and volatility, in a framework where productivity-enhancing public investment could improve future growth potential. We analyze the effects of the central bank's...

Cet article fournit un point de vue opposé au consensus d’« une macroéconomie sans LM ». Elle montre que, lorsque la politique monétaire est spécifiée en termes de règle du taux d’intérêt et la banque centrale ne contrôle pas directement les taux d’intérêt affectant la demande...
