Abstract: How do market power and nominal price rigidity influence inflation dynamics? We formulate a tractable model of oligopolistic competition and sticky prices, and derive closed-form expressions for the pass-through of idiosyncratic and common cost shocks to firms' prices. Using unpublished micro data for Canadian wholesale firms, we estimate that idiosyncratic cost pass-through is incomplete and independent of the sector price stickiness, while common cost pass-through declines with price stickiness. The estimates imply a degree of strategic complementarity that lowers the slope of the New Keynesian Phillips curve by 30% in a one-sector model and by 64% in a multi-sector model.
