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 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...

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...

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...

This paper discusses the incentive to bundle when consumer valuations are non-additive and/or when products are supplied by separate sellers.  Whether integrated or separate, a firm has an incentive to introduce a bundle discount when demand for the bundle is more elastic than the overall...

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,...

Consider the Hotelling linear spatial duopoly with firm uncertainty over the consumer mean. As uncertainty about the mean grows relative to the dispersion of consumers, competitive locations become socially optimal. A limit result for discontinuous, log-concave densities is also established.

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...

This paper provides an empirical examination of third-degree price discrimination in the Swedish newspaper industry. The results show that price discrimination is more prevalent in competitive markets and among newspapers with low market shares. This supports predictions from recent theoretical...
