Competitive differential pricing

چکیده
This paper analyzes welfare under differential versus uniform pricing across oligopoly markets that differ in costs of service. We establish necessary and sufficient conditions on demand properties---cross/own elasticities curvature---for by symmetric firms to raise aggregate consumer surplus, profit, total welfare. The analysis reveals intuitively why is generally beneficial though not always---including profit can fall, unlike for monopoly---and it more than oligopoly third-degree price discrimination. When have asymmetric costs, however, reduce or surplus even with `simple' demands such as linear.

Simple Competitive Internet Pricing ∗
It is widely recognised that pricing is required to control congestion on the Internet. One lesson that has emerged from many proposals is that any price system should be simple and robust to competition. This is highlighted in the question currently under debate in the market for Internet services: should usage prices should be employed at all? In a duopoly model with overall positive network ...
متن کاملOn Competitive Nonlinear Pricing∗
A buyer of a divisible good faces several identical sellers. The buyer’s preferences are her private information, and they may directly affect the sellers’ profits (common values). Sellers compete by posting menus of nonexclusive contracts, so that the buyer can simultaneously and privately trade with several sellers. We focus on the finitetype case, and we provide a full characterization of pu...
متن کاملSimple Competitive Internet Pricing
The Internet is free of charge by nature but since it is being adopted as infrastructure for wide communications networks it turns into a business. The pricing is a feature that was not taken into account when engineering Internet networks. This is one of the major problems that new infrastructures have to solve in order to provide Internet services and make it profitable. This paper presents t...
متن کاملCompetitive Nonlinear Pricing and Bundling∗
We examine the impact of multiproduct nonlinear pricing on profit, consumer surplus and welfare in a duopoly. When consumers buy all their products from one firm (the one-stop shopping model), nonlinear pricing leads to higher profit and welfare, but usually lower consumer surplus, than linear pricing. By contrast, in a unit-demand model where consumers may buy one product from one firm and ano...
