The importance of the stimulus packages that were injected in most advanced economies from the start of the financial crisis and the speed at which budgets are now being consolidated in Europe has revived the long-lasting debate on the size of fiscal multipliers. In this study, we focus on...

We analyze the euro area business cycle in a medium scale DSGE model where we assume two stochastic trends: one on total factor productivity and one on the inflation target of the central bank. To justify our choice of integrated trends, we test alternative specifications for both of them. We do...

We investigate the ability of monetary policy rules to implement a unique equilibrium outcome when the enforcement of rules is limited. We combine the approach of Bassetto (2005) and Atkeson et al. (2010) to study implementation and the one by Chari and Kehoe (1990) to allow policy deviations....

This paper investigates the ability of monetary policy rules to coordinate private agents' expectations when the enforcement of rules is limited. We show that limited enforcement precludes diverging inflation paths ensuring that nominal variables remain bounded in equilibrium. When applied to...

Whereas the bulk of the literature on DSGE models provides a rationale for inflation targeting strategies, there is no model doing such a job for the strategy implemented for almost ten years now by the Eurosystem and known as the "two-pillar monetary policy strategy". We try to address this...

In this paper, we provide solution methods for non-linear rational expectations models in which regime-switching or the shocks themselves may be "endogenous," i.e. follow state-dependent probability distributions. We use the perturbation approach to find determinacy conditions, i.e. conditions...

With the European debt crisis, the role of assets accepted by the Eurosystem as collateral for refinancing operations took on a new place in the public debate, as, against a backdrop of shifting demand for refinancing, movements in European bond prices led to significant fluctuations in the...

This paper studies how private demand for public liquidity affects the independence of a central bank vis-à-vis the fiscal authority. Whereas supplying liquidity to the private sector creates degrees of freedom for fiscal and monetary authorities vis-à-vis each other, we show that the...
