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...

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...

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...
