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...

We analyse the roles of social network topology and size on the monopoly pricing of network goods in a market, where consumers interact with each other and are characterised by their social relations. The size effect is the well-known network externalities phenomenon, while the topological...

We analyse how consumer heterogeneity affects buying behaviour and the monopoly pricing of a network good and its usage. Under perfect information, sufficiently high heterogeneity yields a unique equilibrium, and the unit price is increasing in heterogeneity. Under incomplete information, we...

In earlier theoretical framework, Morris and Shin (2002) highlight the potential dangers of transparency policy. In particular, public announcements may be detrimental to social welfare. Later, Morris and Shin (2005) uphold that more precise communication can degrade the signal value of prices....

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...

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...

In liberalized electricity markets strategic firms compete in an environment characterized by fluctuating demand and non-storability of electricity. While spot market design under those conditions by now is well understood, a rigorous analysis of investment incentives is still missing. Existing...

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 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...
