We examine an infinite horizon model of quality growth in a durable goods monopoly market. The monopolist generates new quality improvements over time and can sell any available qualities, in any desired bundles, at each point in time. Consumers are identical and for a quality improvement to have value the buyer must possess previous qualities: goods are upgrades. We show that subgame perfect e...

Digital-age technologies promise to revolutionize the market for academic journals as they have other media. We model journals as intermediaries linking authors with readers in a twosided market. We use the model to study the division of fees between authors and readers under various market structures, ranging from monopoly to free entry. The results help explain why print journals traditionall...

When competing firms target information towards specific consumers through direct marketing activities, complete segmentation of markets can result. We analyze a two-stage duopoly where, prior to price competition, each firm targets information to specific consumers and only consumers informed by a firm can buy from it. This has the effect of endogenously determining market segments in a model ...

This paper presents a model of a global CO 2 emissions market as envisaged in the Kyoto Protocol. Using an agent-based simulation, six trading regions abstracted from the Annex-I countries are allowed to trade within a market defined by 1) perfect competition, 2) monopoly, 3) monopsony, and 4) unrestrained strategic battling between powerful buyers and sellers. Cost analysis was performed for v...

Two financial services firms (FSFs) produce information on future returns from risky assets, incorporate this information in a report and sell the reports to investors. The FSFs make strategic choices of the quality, differentiation and prices of their reports. Their optimal strategic choices of quality and differentiation divide the market for the report into three segments. Each FSF has a mon...

Classroom market experiments can complement the theoretical orientation of standard industrial organization courses. This paper describes various experiments designed for such courses, and presents details of a multi-market game with entry and exit. In this experiment incumbents have a cost advantage in their ‘home’ markets, and mobile firms decide which market to enter. After entry decisions a...

This paper presents a theory of the market provision of broadcasting and uses it to address the nature of market failure in the industry. Advertising levels may be too low or too high, depending on the relative sizes of the nuisance cost to viewers and the expected benefits to advertisers from contacting viewers. Market provision may allocate too few or too many resources to programming and the...

This paper presents an empirical assessment of the degree of competition within the Jamaican banking sector during the period 1998 to 2009. We employ a dynamic version of the Panzar Rosse Model to estimate market power among the sample of banks that constitute over 90 percent of the banking market. Using the conventional statistical tests, we are unable to reject monopoly/perfect collusion for ...

This paper takes a critical look at electronic markets. Through an examination of Hong Kong's air cargo industry, where an electronic network recently has begun its operation, we argue that none of the key industry stakeholders stand to gain from an electronic market. Instead we found that the existing electronic network has limited its service to carefully preserve the distribution of power am...

We address the problem faced by innovators who have an idea for a marketable product but must hire employees to bring the product to the market. Information leakage implies that newly hired employees become informed of the idea and may attempt to bring the product to the market themselves. We develop a bargaining model to analyze this situation. In this model, employees’ rents endogenously reße...
