Micro fact #3) At the firm level, prices are nonlinear in reset gaps, leading to a steeper slope of the NKPC when the distribution of gaps shifts. 8/14

Micro-to-macro fact #4) The nonlinearities at the firm level result in a nonlinear relation between aggregate inflation and aggregate frequency. 9/14

Quantitative exercise: Construct a measure of aggregate marginal cost and feed it into the model as a sequence of impulse responses. The menu-cost model captures well both amplitude and cyclicality of inflation, in both high and low inflation regimes. 10/14

Finally, we propose a “Nonlinear Calvo model” embedding nonlinearities in a tractable framework. Combines Caballero-Engel's inflation formula, quadratic hazard function, Calvo-like reset price equation. It has an analytical solution for inflation! 12/14
