In this article we study patterns of vertical product differentiation in a multi-product monopoly using a random utility model. Prior research shows that applying such a model in a multi-product setting implies symmetric patterns of product differentiation in which all product variants of a...

We analyze third degree price discrimination by an upstream monopolist to a continuum of heterogeneous downstream firms. The novelty of our approach is to recognize that customizing prices may be costly. As a consequence, partial price discrimination arises in equilibrium; in particular,we...

We analyze the impact of product bundling in experimental markets. One firm has monopoly power in a first market but competes with another firm à la Cournot in a second market. We compare treatments where the multi-product firm (i) always bundles, (ii) never bundles, and (iii) chooses whether...

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 analyzes tying and bundling as an entry deterrence tool. It shows that a multi-product firm can defend its monopoly position in one market via tying even when it does not have market power in another market. This is shown on a model with two complementary goods, each of which is...

I develop a multiproduct nonlinear pricing model where a firm sells both discrete and continuous goods/services to consumers with multidimensional heterogeneity. I derive the optimal selling mechanism and provide primitive conditions under which different bundling strategies arise. Exploiting...

The constitutional conception of market integration within the European Union entails creating a level playing field for competition in the consolidated banking sector. The financial crisis of 2008 brought with it the need to proceed with care as it rolled back the gains of improving competitive...

If buyers can choose to initiate bargaining with a seller, how does this alter the price that the seller 'posts' in the market? And does the option of bargaining raise or lower expected welfare?This paper develops a simple model to answer these questions. With a single seller, the potential for...

In economics, market failure is a situation in which the allocation of goods and services is not efficient. Monopoly power and asymmetric information are amongst the major causes of market failure. We plan to identify if there is a market failure in the dietary market. The present study plans to...
