Nonlinear pricing is that which is in direct proportion to the quantity purchased; for example, airlines' frequent flyer bonuses. The first part of this work consists of a non-mathematical discussion of this pricing; the second is more technical and aimed at readers interested in advanced topics.

Masterful book ... The bibliography itself is exhaustive and will be the standard source of reference for years to come. Robert Wilson has written an important book ...

"Anyone interested in pricing in imperfectly competitive and regulated markets can learn a great deal from Nonlinear Pricing. It will be a standard advanced text and reference for years to come....Nonlinear Pricing has increased both economists' understanding of nonlinear tariffs and practitioners' ability to implement them in a variety of settings. Like other important and enduring works, Nonlinear Pricing poses questions no less interesting than those it answers."--Journal of Political Economy "Anyone interested in pricing in imperfectly competitive and regulated markets can learn a great deal from Nonlinear Pricing.
