We build an agent-based model that can be employed as a laboratory to explore the e ects of
alternative combinations of scal and monetary policies under di erent income distribution
regimes. In particular, this setting allows us to evaluate scal rules in a dynamic environment
subject to banking crises and deep recessions. Portraying an economy with heterogeneous
capital- and consumption-good rms, heterogeneous banks, workers/consumers, a central
bank and a Government, the model is able to reproduce a wide array of macro, micro
empirical regularities, as well stylized facts concerning banking crises. Simulation results
show that there are strong interactions between di erent types of scal and monetary policies.
The appropriate policy mix to stabilize the economy requires an unconstrained scal policy,
where automatic stabilizers are free to dampen business cycles
uctuations, and a monetary
policy targeting both price and output stability. Instead, scal rules such as the Stability
and Growth Pact or the Fiscal Compact always depress the economy without improving
public nances, even when escape clauses in case of recessions are considered. In that,
austerity policies are self-defeating. Furthermore, the negative e ects of scal rules are
magni ed by conservative monetary policies focused on in
ation stabilization only. Finally,
our conclusions about the e ects of di erent monetary and scal policies become sharper as
the level of income inequality increases.

Tania Treibich
Post Doctoral Researcher
University of Maastricht

I just started as a Post-Doctoral researcher at the University of Maastricht (AE2 department), after receiving my PhD in Economics from the University of Nice (GREDEG lab) and the Scuola Superiore Sant'Anna of Pisa (LEM), under the supervision of Professors Jean-Luc Gaffard and Giovanni Dosi.

My general research interest relates to the transmission mechanisms between the financial sector and the real economy as well as the fiscal and economic costs of banking crises. I have also worked on micro issues such as the link between industrial dynamics and trade, or firms' access to banking finance and their performance.
