This paper develops two brand-level demand models, where prices are treated as endogenous, to estimate unilateral market power in a representative product-differentiated oligopolistic food market. The results are estimated using point-of-purchase scanner data and are used to quantify the impact...

The Orbit demand model allows the magnitude of the calibration to stated purchase intentions to vary based on the magnitude of the stated quantities. Using an empirical example of stated trips, we find that the extent of calibration varies substantially with less correction needed at small...
