business and finance marketing and advertisingHow does a two part tariff differ from bundling?
Thereof, why do firms use two part tariffs?
A two-part tariff (TPT) is a form of price discrimination wherein the price of a product or service is composed of two parts - a lump-sum fee as well as a per-unit charge. It is designed to enable the firm to capture more consumer surplus than it otherwise would in a non-discriminating pricing environment.
Thereof, what determines a two part tariff?
One common model for a two-part tariff is to set the per-unit price equal to marginal cost (or the price at which marginal cost meets the consumers' willingness to pay) and then set the entry fee equal to the amount of consumer surplus that consuming at the per-unit price generates.
Second-degree price discrimination occurs when a company charges a different price for different quantities consumed, such as quantity discounts on bulk purchases.
