ALL TUNA IS NOT CREATED EQUAL: THE EXISTENCE OF QUANTITY SURCHARGES DUE TO PRODUCT DIFFERENTIATION.

Abstract

Quantity surcharges exist when unit prices are higher for larger packages. We hypothesize that various sizes of goods are differentiated products, and this explains some surcharges. Estimating a random-coefficients logit demand model, we examine own and cross elasticities to determine the level of differentiation between products with different size packages.Marketing,
