This paper studies the importance of firm-level price markup dynamics for business cycle fluctuations.

Importantly, I find substantial heterogeneity in markup cyclicality across firms, with small firms having significantly more counter-cyclical markups than large firms. Then, I develop a general equilibrium model by embedding customer capital (due to deep habits as in Ravn, ...

Markup Cyclicality: A Tale of Two Models

Many models in the business cycle literature generate counter-cyclical price markups. This paper examines if the prominent models in the literature are consistent with the empirical findings of micro-level markup behavior in Hong (2016). In particular, I test the markup behavior of the following two models: (i) an oligopolistic competition model, and (ii) a New Keynesian model with heterogeneous price stickiness. First, I explore the Atkeson and Burstein (2008) model of oligopolistic competition, in which markups are an increasing function of firm market shares. Coupled with an exogenous ...
