Working papers

[1] The Two Faces of Information (with G. Ordoñez)

Information helps individuals to deal with fluctuations (the good face), but it also increases market fluctuations (the bad face).

[2] Time-consistent Fiscal Guarantee for Monetary Stability (with E. Mengus)

An authority can credibly sustain the real value of fiat money only if agents trust that it will resist the temptation to raise seigniorage once they buy money.

[3] Learning from Prices: Amplification and Business Fluctuations (with R. Chahrour) R&R REStud

Expectations-driven aggregate fluctuations may originate with small productivity shocks when agents learn from competitive prices. [slides]

[4] Breaking the Spell with Credit-Easing. Self-Confirming Credit Crises in Competitive Search Economies. (with R. Marimon) 

We introduce Self-Confirming Equilibria in competitive search economies as potential explanation of credit freezes and the success of credit-easing policies. [slides]

[5] Can More Public Information Raise Uncertainty? The International Evidence on Forward Guidance. (with M. Ehrmann, P. Hoffmann, and G. Strasser) 

Evidence shows that weak forms of Forward guidance can raise uncertainty. A market externality in the aggregation of information can explain this.
