Package size and price discrimination in the paper towel market

Estimates from a structural model of consumer behavior and firm conduct are used to decompose the extent to which quantity discounts for paper towels are consistent with second degree price discrimination as opposed to cost differences across sizes. Counterfactual exercises assuming that firms offer only one package size or charge uniform prices across sizes indicate that competition in the multi-roll package size segment results in increased consumer surplus and lower prices for all consumers.
