We re-examine the view that a ban on price discrimination in input markets is particularly desirable in the presence of buyer power. This argument crucially depends on an inverse relationship between downstream firms' profits and the uniform input price. Assuming different input efficiencies...

We consider competing mobile marketers that complement geo-targeting with behavior-based pricing and send personalized offers to customers. Firms observe consumers’ locations and can infer their (heterogeneous) responsiveness to discounts from purchase histories. The overall profit effect of...

Informationstechnologien erlauben Firmen immer mehr persönliche Daten über ihre Kunden zu sammeln. Mit diesen Daten werden Kundenprofile erstellt über Vorlieben für bestimmte Marken, Zahlungsbereitschaft oder Wechselbereitschaft bei Preiserhöhungen. Zudem kommt es immer häufiger vor, dass...

This paper analyses the problem of price discrimination in a market where consumers have heterogeneous preferences both over a horizontal parameter (brand) and a vertical one (quality). Discriminatory contracts are characterised for different market structures. It is shown that price dispersion,...

We analyze the effect of different pricing schemes on horizontally differentiated firms' ability to sustain collusion when customers have the possibility to combine (or mix) products to achieve a better match of their preferences. To this end, we compare two-part tariffs with linear prices and...

While competition between firms producing substitutes is well understood, less is known about rivalry between complementors. We study the interaction between firms in markets with one-way essential complements. One good is essential to the use of the other but not vice versa, as arises with an...

We consider a model of a monopolistic network operator who sequentially offers two-parted access charges to symmetric downstream firms. We are particularly interested in analyzing an alternative to current regulatory practice of prescribing access. In particular, we look at the possibility of...

We study the pricing policy equilibria emerging in a partial collusion duopolistic framework where firms in the first stage of the game choose non-cooperatively whether to price discriminate or not, and from the second stage onward collude on prices.When the discount factor is particularly high...

Recent developments in information technology (IT) have resulted in the collection of a vast amount of customer specific data. As the IT advances the quality of such information improves. We analyze a sequential spatial model of oligopolistic third degree price discrimination where the firms use...
