We derive a New Keynesian Phillips Curve under Calvo staggered pricing and price competition. Firms strategic interactions induce price adjusters to change their prices less when there are more firms that do not adjust. This reduces the slope of the Phillips curve and generates an additional...

We derive a New Keynesian Phillips curve under Calvo staggered pricing and endogenous market structures with Bertrand competition. Both strategic interactions and endogenous business creation strengthen the nominal rigidities. Price adjusters change their prices less when there are more direct...

We reconsider the New-Keynesian model with staggered price setting when each market is characterized by a small number of firms competing in prices à la Bertrand rather than a continuum of isolated monopolists. Price adjusters change their prices less when there are more firms that do not...
