Information about a new or non-frequently purchased product is often produced by both sides of the market. We construct a monopoly pricing model consisting of both seller's information disclosure and consumer's information acquisition. The presence of consumer search, which lowers the...

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...

Advertising is commonly regarded as a strategic tool to increase demand and steal business from competitors. The present work studies the competitive effects of advertising in a two-period game with incomplete information about the opponent's cost structure. Bagwell and Ramey (1988) showed that...

The literature on the effects of market concentration in platform industries or two-sided markets often compares the competitive outcome against a benchmark. This benchmark is either the “joint management” solution in which one decision maker runs all platforms or a “pure” monopoly with...

We propose both a monopoly and a duopoly model of a two-sided market. Both settings are fully comparable, as we impose a homogeneous good produced at zero costs without capacity constraints, as well as identical parameterization of market sizes. We determine the duopoly equilibrium and the...

This paper studies the implications of consumer reference dependence in market competition. If consumers take some product (e.g., the first product they have considered) as the reference point in evaluating others and exhibit loss aversion, then the more "prominent" firm whose product is taken...

This paper develops a model of pricing and advertising in a matching environment with capacity constrained sellers and uncoordinated buyers. Sellers' search intensity attracts buyers only probabilistically through costly informative advertisement. Equilibrium prices and profit maximizing...

We model comparative advertising as brands pushing up own brand perception and pulling down the brand image of targeted rivals. We watched all TV advertisements for OTC analgesics 2001-2005 to construct matrices of rival targeting and estimate the structural model. These attack matrices identify...

In this study, we analyze a dynamic duopoly game in which firms can use advertising and price as competitive tools. The market is assumed to be completely covered in the sense that all consumers purchase a product from one of the two firms. We assume that advertising creates a positive...

In this paper we introduce two models of opinion dynamics in oligopoly markets and apply them to a situation, where a new entrant challenges two incumbents of the same size. The models differ in the way the two forces influencing consumer choice - (local) social interactions and (global)...
