All-Units Discounts As A Partial Foreclosure Device, Yong Chao, Guofu Tan

Yong Chao

All-units discounts (AUD) are pricing schemes that lower a buyer’s marginal price on every unit purchased when the buyer’s purchase exceeds or is equal to a pre-specified threshold. The AUD and related conditional rebates are commonly used in both final-goods and intermediate-goods markets. Although the existing literature has thus far focused on interpreting the AUD as a price discrimination tool, investment incentive program, or rent-shifting instrument, the antitrust concerns on the AUD and related conditional rebates are often their plausible exclusionary effects.

In this article, we investigate strategic effects of volume-threshold based AUD used by a dominant firm in the …

Cartelization Through Buyer Groups, Chris Doyle, Martijn Han

Martijn A. Han

Retailers may enjoy stable cartel rents in their output market through the formation of a buyer group in their input market. A buyer group allows retailers to commit credibly to increased input prices, which serve to reduce combined final output to the monopoly level; increased input costs are then refunded from suppliers to retailers through slotting allowances or rebates. The stability of such an ‘implied cartel’ depends on the retailers’ incentives to source their inputs secretly from a supplier outside of the buyer group arrangement at lower input prices. Cheating is limited if retailers sign exclusive dealing or minimum purchase …

Strategic Effects Of Three-Part Tariffs Under Oligopoly, Yong Chao

Yong Chao

The distinct element of a three-part tariff, compared with linear pricing or a two-part tariff, is its quantity target within which the marginal price is zero. This quantity target instrument enriches the firm's strategy set in dictating the competition to a specific level, even in the absence of usual price discrimination motive. With general differentiated linear demand system, the competitive effect of a three-part tariff in contrast to linear pricing depends on the degree of substitutability between products: competition is intensified when two products are more differentiated, yet softened when two products are more substitutable.
