This work revisits the recent disinflation process in Brazil and finds that solely the agents' perception that a policy rupture could occur is capable of triggering a change in the way firms and households used to behave in their pricing and consuming decisions. This change was captured by...

This paper aims to contribute to the research agenda on the sources of price rigidity. Based on broadly accepted assumptions on the behavior of economic agents, we show that firms’ competition can lead to the adoption of sticky prices as a sub-game perfect equilibrium strategy to optimally...

In standard New Keynesian models, in which staggered pricing is the only nominal rigidity and shocks to preferences or technology are the only source of fluctuations, the literature has long agreed that the divine coincidence holds: the monetary authority is able to simultaneously stabilize the...

I show that the combination of small positive trend inflation with staggered prices may account for the large relative volatilities found in US labor market data. The model does not have any wage rigidity and is hit only by an aggregate technology shock. The calibration procedure uses standard...

I assess the optimal policy to be followed by a welfare-concerned central bank when assigned an inflation target that is not necessarily welfare-optimal. I treat the inflation target as the trend inflation and I have three main contributions: (i) a welfare-based loss function fully derived under...
