Intertemporal price discrimination – Practice of separating consumers with different demand functions into different groups by charging different prices at different points in time.
Peak-load pricing – Practice of charging higher prices during peak periods when capacity constraints cause marginal costs to be high.
Two-part tariff – Form of pricing in which consumers are charged both an entry and a usage fee.
Single consumer: Usage fee should be set equal to MC and entry fee equal to the consumer surplus for each customers.
Two consumers: Set the usage fee above MC and then set entry fee equal to the remaining consumer surplus of the consumer with the smaller demand.
