Financial crises are often associated with an endogenous credit reversal followed by a fall in asset prices and serious disruptions in the financial sector. To account for this sequence of events, this paper constructs a model where the excessive risk-taking of portfolio investors leads to a...

We study the macroeconomic implications of time-varying precautionary saving within a general equilibrium model with borrowing constraint and both aggregate shocks and uninsurable idiosyncratic unemployement risk. Our framework generates limited cross-sectional household heterogeneity as an...

This paper explores the relationship between the severity of credit constraints and long run inflation in a simple non Ricardian setting. It is shown that a low positive inflation can loosen credit constraints and that this effect yields a theory of the optimal long run inflation target with no...

This paper analyzes the long-run effect of monetary policy when credit constraints are taken into account. This analysis is carried on in a heterogeneous agents framework in which infinitely lived agents can partially self-insure against income risks by using both financial assets and real...

This paper analyses the effect of transitory increases in government spending when public debt is used as liquidity by the private sector. Aggregate shocks are introduced into an incomplete-market economy where heterogenous, infinitely-lived households face occasionally binding borrowing...

We formulate and estimate a tractable macroeconomic model with time-varying precautionary savings. We argue that the latter affect aggregate fluctuations via two main channels: a stabilizing aggregate supply effect working through the supply of capital; and a destabilizing aggregate demand...

During the recent inflation episode, the paradigm of separated objectives for monetary and fiscal policies has shown some limits. Fiscal policies have helped mitigate inflation. We advocate for the emergence of a new paradigm that gives equal consideration to fiscal and monetary policies and...

Policy recommendations:• The Recovery and Resilience Facility (RRF), which makes up the bulk of the ‘Next Generation EU' plan, with 672.5 billion euros (€) in loans and grants (out of a total of €750 billion), has given new momentum to policy and political coordination in the EU. As...
