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...

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...

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 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...

In this paper, we solve a large class of non-linear rational expectations models with regime switching, i.e. recurring shifts in parameters. The regime-switches and the shocks may follow state-dependent probability distributions. Using a perturbation approach, we first prove that sufficient...

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 argues that central bankers should temporarily raise inflation when anticipating liquidity traps to signal their credibility to forward guidance policies. As stable inflation in normal times either stems from central banker's credibility, e.g. through reputation, or from his aversion...
