Existing menu cost models, when parameterized to match the micro-price data, cannot reproduce the extent to which the fraction of price changes increases with inflation. In addition, in the presence of strategic complementarities, they predict implausibly large menu costs and misallocation. We...

We study aggregate capital dynamics in an investment model with idiosyncratic productivity shocks, fixed capital adjustment costs, and irreversibility driven by a wedge between capital purchase and resale prices. We derive sufficient statistics capturing the role of investment frictions on...

We empirically characterize episodes of large inflation surges that have been observed worldwide in the last three decades. We document four facts. (1) Inflation surges tend to be persistent, with the duration of disinflation exceeding that of the initial inflation increase. (2) Surges are...

We develop a tractable sticky price model in which the fraction of price changes evolves endogenously over time and, consistent with the evidence, increases with inflation. Because we assume that firms sell multiple products and choose how many, but not which, prices to adjust in any given...

This paper studies earnings inequality and dynamics in Argentina between 1996 and 2015. Following the 2001--2002 crisis, the Argentine economy transitioned from a low- to a high-inflation regime. At the same time, the number of collective bargaining agreements increased and the minimum wage...

We develop a theory of labor markets in a monetary economy with four realistic features: search frictions, worker productivity shocks, wage rigidity, and two-sided lack of commitment. Due to the non-Coasean nature of labor contracts, inefficient job separations occur in the form of endogenous...

This paper studies earnings inequality and dynamics in Argentina between 1996 and 2015. Following the 2001-2002 crisis, the Argentine economy transitioned from a low- to a high-inflation regime, while collective bargaining and the minimum wage gained influence. This transition was associated...

How does an economy's capital respond to aggregate productivity shocks when firms make lumpy investments? We show that capital's transitional dynamics are structurally linked to two steady‐state moments: the dispersion of capital to productivity ratios—an indicator of capital...
