This paper investigates the price decision making and channel performance under cost misrepresentation at the retail stage. In the standard double marginalization game, we introduce a preliminary stage, where the retailer can misrepresent her constant marginal cost. We give respective sufficient...

This paper investigates the pass-through of an excise tax imposed on a monopoly firm with constant marginal cost. The optimal price increases as tax increases for any demand function. Tax pass-through is globally under or in excess of 100% according as the direct demand function is log-concave...
