Brazil has had a long period of high inflation. It peaked around 100 percent per year in 1964, decreased until the first oil shock (1973), but accelerated again afterward, reaching levels above 100 percent on average between 1980 and 1994. This last period coincided with severe balance of...

We propose and implement an index of macroeconomic vulnerability to foreign shocks based on a structural time-varying bayesianVARwith a block-exogeneity hypothesis for a given pair of a large economy and a small open economy. The index is based on the sum of the responses of the small open...

This paper proposes a model of sovereign default that features interest rate multiplicity driven by rollover risk. Our core mechanism shows that the possibility of a rollover crisis by itself can lead to high interest rates, which in turn reinforces the rollover risk. By exploiting...

We show that explicitly modeling primary commodities in an otherwise totally standard incomplete markets open economy model can go a long way in explaining the Mussa puzzle and the Backus-Smith puzzle, two of the main puzzles in the international economics literature.

We assess the quantitative relevance of expectations-driven sovereign debt crises, focusing on the Southern European crisis of the early 2010s and the Argentine default of 2001. The source of multiplicity is the one in Calvo (1988). Key for multiplicity is an output process featuring long...
