This paper augments a relatively standard dynamic general equilibrium model with financial frictions in order to quantify the macroeconomic effects of the credit deepening process observed in many Latin American (LA) countries in the last decade, most notably in Brazil. In the model, a stylized...

There is ample evidence that the frequency of price adjustments differs substantially across sectors. This paper introduces sectoral heterogeneity in price stickiness into an otherwise standard sticky price model to study how it affects the dynamics of monetary economies. Qualitative and...

We quantify the informational content of statements issued by the interest-rate setting com-mittee of the Central Bank of Brazil (COPOM), building on the methodology developed by Luccaand Trebbi (2011). Using Google search queries, we measure the extent to which each COPOM statement is perceived...

We combine questions from the Michigan Survey about the future path of prices, interest rates, and unemployment to investigate whether households are aware of the basic features of U.S. monetary policy. Our Öndings support the view that at least some groups of households form their expectations...

For a given frequency of price changes, the real effects of a monetary shock are smaller if adjusting firms are disproportionately likely to have last set their prices before the shock. This type of selection for the age of prices provides a complete characterization of the nature of pricing...

We study how real exchange rate dynamics are affected by monetary policy in dynamic, stochastic, general equilibrium, sticky-price models. Our analytical and quantitative results show that the source of interest rate persistence - policy inertia or persistent policy shocks - is key. When the...
