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...

Since the late 70s and the first two oil shocks, many economic studies have explored the link between changes in oil prices and global economic growth. However, the causes of the variations in oil price have changed over this period. Thus the impact of these shocks on the economy may also...

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...

In this paper, we provide determinacy conditions, i.e. conditions ensuring the existence and uniqueness of a bounded solution, in a purely forward-looking linear Markov switching rational expectations model. We thus settle the debate between Davig and Leeper (2007) and Farmer et al. (2010). 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...

We assess the effect of accepting illiquid assets as collateral at the central bank on banks' lending activity. We study the lending activity of the 177 largest banks in the Euro area between 2011m1 and 2014m12 and the composition of their pool of collateral pledged with the Eurosystem. Panel...

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....
