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 nonneutrality predict a nearly constant ...

Nonlinear Inflation Dynamics in Menu Cost Economies
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 resolve these shortcomings using a multi-product menu cost model that features two key ingredients. First, the products sold by a firm are imperfect substitutes. Second, strategic complementarities are at the firm, not product level. In contrast to existing models, the fraction of price changes ...

Pricing decisions in an experimental dynamic stochastic general equilibrium economy
We construct experimental economies, populated with human subjects, with a structure based on a nonlinear version of the New Keynesian Dynamic Stochastic General Equilibrium (DSGE) model. We analyze the behavior of firms' pricing decisions in four different experimental economies. We consider how well the experimental data conform to a number of accepted empirical stylized facts. Pricing patterns mostly conform to these patterns. Most price changes are positive, and inflation is strongly correlated with average magnitude, but not the frequency, of price changes. Prices are affected negatively ...

Real Rigidities, Firm Dynamics, and Monetary Nonneutrality: The Role of Demand Shocks
We propose a parsimonious framework for real rigidities, in the form of strategic complementarities, that can generate real and nominal dynamics and match key features of the data across several literatures. Existing menu-cost models featuring strategic complementarities require unrealistically volatile shocks to idiosyncratic productivity to be consistent with pricing moments. We develop a simple menu-cost model with strategic complementarities along with idiosyncratic productivity and demand shocks that are disciplined by the data. This approach allows us to overcome previous criticism from ...

The Roles of Price Points and Menu Costs in Price Rigidity
Macroeconomic models often generate nominal price rigidity via menu costs. This paper provides empirical evidence that treating menu costs as a structural explanation for sticky prices may be spurious. Using scanner data, I note two empirical facts: (1) price points, embodied in nine-ending prices, account for approximately two-thirds of prices; and (2) at the conclusion of sales, post-sale prices return to their pre-sale levels more than three-fourths of the time. I construct a model that nests roles for menu costs and price points and estimate model variants. Excluding the two facts yields ...
