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...

A common sales tactic is for a seller to encourage a potential customer to make her purchase decision quickly, before she can investigate rival deals in the market.  We consider a market with sequential consumer search in which firms can achieve this either by making an exploding offer (which...

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...

A seller wishes to prevent the discovery of rival offers by its prospective customers.  We study sales techniques which serve this purpose by making it harder for a customer to return to buy later after a search for alternatives.  These include making an exploding offer, offering a "buy-now"...

This paper examines the implications of "prominence" in search markets.  We model prominence by supposing that the prominent firm will be sampled first by all consumers.  If there are no systematic quality differences among firms, we find that the prominent firm will charge a lower price than...

We examine the impact of multiproduct nonlinear pricing on profit, consumer surplus and welfare in a duopoly. When consumers buy all their products from one firm (the one-stop shopping model), nonlinear pricing leads to higher profit and welfare, but often lower consumer surplus, than linear...
