We construct, and then estimate by maximum likelihood, a tractable dynamic stochastic general equilibrium model with incomplete insurance and heterogenous agents. The key feature of our framework is that cross-sectional heterogeneity remains finite dimensional. The solution to the model thus...

We study the macroeconomic effects of rational asset bubbles in an overlapping-generations economy where asset trading requires specialized intermediaries and where agents freely choose between working in the production or in the financial sector. Frictions in the market for deposits create...

We study optimal monetary policy in a heterogeneous agent new Keynesian economy. A utilitarian planner seeks to reduce consumption inequality, in addition to stabilizing output gaps and inflation. The planner does so both by reducing income risk faced by households, and by reducing the...

We study optimal monetary policy in an analytically tractable Heterogeneous Agent New Keynesian model with rich cross-sectional heterogeneity. Optimal policy differs from that in a representative agent model because monetary policy can affect consumption inequality by reducing both idiosyncratic...

This paper evaluates the risk of zombification of the French economy during the sanitary crisis, as a result of the unconditional financial support provided to firms by public authorities. We develop a simple theoretical framework based on a partial-equilibrium model to simulate the liquidity...

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...

[Highlights] Fully-fledged federations assign fiscal policy stabilisation largely to the federal level, based on a relatively large budget. In the euro area, a large federal budget is unrealistic at the current level of political and societal integration, and fiscal stabilisation will continue...

The reconsideration of the complex set of European fiscal rules should be a priority in terms of euro-area reform. The rules contributed to excessive fiscal austerity during the crisis, thus helping to aggravate and prolong its economic, social and political consequences. Moreover, either...

Of the many good ideas currently being discussed in Europe, the most interesting proposal is to let national unemployment schemes manage the regular business cycle, and to provide European financing to extend the duration of unemployment benefits during a crisis period.
