Pricing model analysis based on shelf life for perishable foods bundling selling

In order to make the retailer pricing decision reflect the quality fluctuation of perishable food, the bundling selling model based on the shelf life for perishable food was established by taking pasteurized milk as illustration after effectively partitioning customer-groups among the whole market. By analyzing the relationship between the fluctuation of quality level and the change of shelf life for the same kind of perishable food, and studying the self-selection constraint conditions for two customer-groups in the bundling selling model, the pay-off conditions in the two different cases were put forward separately. In some conditions, adopting bundling selling based on shelf life can bring higher profits to retailers.
