Firms’ market power, measured by markups, has risen substantially and unequally across sectors. To evaluate the implications of these trends for monetary non-neutrality, we develop a quantitative menu cost model that covers multiple sectors with heterogeneous degrees of market competition. Two...

To model the observed slow response of aggregate real variables to nominal shocks, most macroeconomic models incorporate real rigidities in addition to nominal rigidities. One popular way of modelling such a real rigidity is to assume a non-constant demand elasticity. By using a homescan data...

I study a general equilibrium menu cost model with a continuum of sectors, idiosyncratic and aggregate shocks, and the novel feature that each sector consists of strategically engaged firms. Compared to an economy with monopolistically competitive sectors—separately parameterized to match the...
