I analyze the implications of bundling on price competition in a market with complementary products. Using a model of imperfect competition with product differentiation, I identify the incentives to bundle for two types of demand functions and study how they change with the size of the bundle....

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...

This paper explores tying in the situation where a multi-product firm without monopoly power competes against several single-product firms. I consider two markets: one for a horizontally differentiated good, the other for a homogeneous good. As opposed to the widely accepted opinion that tying...

This paper extends the standard model of bundling to allow products to be substitutes and for products to be supplied by separate sellers.  Whether integrated or separate, firms have an incentive to introduce a bundling discount when demand for the bundle is elastic relative to demand for...

The paper offers an overview of the literature on bundling in the telecommunications sector and its application in the Spanish market. We argue that the use of bundling in the provision of services is associated to technological reasons. Therefore, there appears no need to regulate bundling...

This paper presents a simple model of regulated/deregulated shopping hours and bundling in markets where consumers have preference in shopping time. We show that, for a range of parameters, the market will change from a duopoly with an independent pricing regime when shopping hours are...

Commodity bundling is studied in an environment where the dispersion of valuations unambiguously decreases when two or more goods are sold as a bundle only. Bundling is more likely to dominate separately selling the goods if marginal costs are low relative to the average valuation, or if the...

Produktbündel sind im Wirtschaftsleben allgegenwärtig. Sie können zum einen erhebliche Vorteile für Anbieter und Kunden aufweisen, zum anderen können sie aber auch als Instrument zur Behinderung des Wettbewerbs eingesetzt werden. Die ökonomische und rechtliche Würdigung ist daher sehr...
