Inflation: Drivers and Dynamics 2019 Conference Summary
To provide insights into the processes that drive inflationary dynamics, the Federal Reserve Bank of Cleveland holdsan annual conference on the topic of inflation: “Inflation: Drivers and Dynamics.” This Commentary summarizes thepapers presented at the 2019 conference.

Nonlinear Inflation Dynamics in Menu Cost Economies
Canonical 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. They also predict implausibly large menu costs and misallocation in the presence of strategic complementarities. We resolve these shortcomings by extending the multiproduct menu cost model along two dimensions. First, the products sold by a firm are imperfect substitutes. Second, strategic complementarities are at the firm, not product level. In contrast to standard models, the fraction of price changes increases rapidly ...

A Theory of Non-Coasean Labor Markets
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 quits and layoffs that are unilaterally initiated whenever a worker’s wage-to-productivity ratio moves outside an inaction region. We derive sufficient statistics for the aggregate labor market response to a monetary shock based on the distribution of workers’ wage-to-productivity ratios. These ...

The Inflation Accelerator
We develop a tractable sticky price model in which the fraction of price changesevolves 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 period, our model admits exact aggregation and reduces to a one-equation extension of the Calvo model. This additional equation determines the fraction of price changes. The model features a powerful inflation accelerator – a feedback loop between inflation and the fraction of price changes – which ...

Nonlinear Dynamics in Menu Cost Economies? Evidence from U.S. Data
We show that standard menu cost models cannot simultaneously reproduce the dispersion in the size of micro-price changes and the extent to which the fraction of price changes increases with inflation in the U.S. time-series. Though the Golosov and Lucas (2007) model generates fluctuations in the fraction of price changes, it predicts too little dispersion in the size of price changes and therefore little monetary nonneutrality. In contrast, versions of the model that reproduce the dispersion in the size of price changes and generate stronger monetary non-neutrality predict a nearly constant ...
