This paper surveys recent economic research on price discrimination, both in monopoly and oligopoly markets. Topics include static and dynamic forms of price discrimination, and both final and input markets are considered. Potential antitrust aspects of price discrimination are highlighted...

We investigate three ways in which firms can become "prominent" and thereby influence the order in which consumers consider options. First, firms can affect an intermediary's sales efforts by means of commission payments. When firms pay commission to a salesman, the salesman promotes the product...

This paper surveys models of markets in which some consumers are "savvy" while others are not. We discuss when the presence of savvy consumers improves the deals available to non-savvy consumers in the market (the case of search externalities), and when the non-savvy fund generous deals for...

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 extends the standard model of bundling as a price discrimination device 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...

This paper studies sales techniques which discourage consumer search by making it harder or more expensive to return to buy after a search for alternatives. It is unilaterally profitable for a seller to deter search under mild conditions, but sellers can suffer when all do so. When a seller...

This paper studies a model in which some consumers shop on the basis of price alone, without attention to potential differences in product quality. A firm may offer a low-quality product to exploit these inattentive consumers. In the unique symmetric equilibrium of the model, firms choose prices...

The purpose of this paper is to generalize the results obtained by Sklivas (1987) and Fershtman and Judd (1987) allowing for non-linear demand functions, many players and general attitudes to the risk by the players. We also generalize their set-up by introducing a more general measure of th...

In this paper I analyze the kind of behavior which can be considered evolutively stable in an oligopolistic market

In this paper we study the conjecture that oligopoly or imperfect competition causes more inflation than perfect competiton. We find necessary and sufficient conditions for this to occur.
