Mix-and-match compatibility in asymmetric system markets

This paper shows that the private incentive for mix-and-match compatibility in system markets diverges from the social planner's incentive if competing suppliers are asymmetric in production cost or product quality. There can be too much or too little compatibility when the market is served by fully integrated system suppliers. Also, the market outcome involves socially too much incompatibility in the form of exclusive technological alliances when the market is composed of independent component suppliers. These results contrast with the standard one obtained in the symmetric setup and shed new light on public policy towards compatibility, technological alliances, and bundling practices in system markets

The Essential Role of Securities Regulation

This Article posits that the essential role of securities regulation is to create a competitive market for sophisticated professional investors and analysts (information traders). The Article advances two related theses-one descriptive and the other normative. Descriptively, the Article demonstrates that securities regulation is specifically designed to facilitate and protect the work of information traders. Securities regulation may be divided into three broad categories: (i) disclosure duties; (ii) restrictions on fraud and manipulation; and (iii) restrictions on insider trading-each of which contributes to the creation of a vibrant market for information traders. Disclosure duties reduce information traders\u27 costs of searching and gathering information. Restrictions on fraud and manipulation lower information traders\u27 cost of verifying the credibility of information, and thus enhance information traders\u27 ability to make accurate predictions. Finally, restrictions on insider trading protect information traders from competition from insiders that would undermine information traders\u27 ability to recoup their investment in information. Normatively, the Article shows that information traders can best underwrite efficient and liquid capital markets, and, hence, it is this group that securities regulation should strive to protect. Our account has important implications for several policy debates. First, our account supports the system of mandatory disclosure. We show that, although market forces may provide management with an adequate incentive to disclose at the initial public offering (IPO) stage, they cannot be relied on to effect optimal disclosure thereafter. Second, our analysis categorically rejects calls to limit disclosure duties to hard information and self-dealing by management. Third, our analysis supports the use of the fraud-on-the-market presumption in all fraud cases even when markets are inefficient. Fourth, our analysis suggests that in cases involving corporate misstatements, the appropriate standard of care should, in principle, be negligence, not fraud

Pricing and Information Disclosure in Markets with Loss-Averse Consumers

Abstract: We develop a theory of imperfect competition with loss-averse consumers. All consumers are fully informed about match value and price at the time they make their purchasing decision. However, a share of consumers are initially uncertain about their tastes and form a reference point consisting of an expected match value and an expected price distribution, while other consumers are perfectly informed all the time. We derive pricing implications in duopoly with asymmetric ?rms. In particular, we show that a market may exhibit more price variation the larger the share of uninformed, loss-averse consumers. We also derive implications for ?rm strategy and public policy concerning ?rms’ incentives to inform consumers about their match value prior to forming their reference point

Spatial asymmetric duopoly with an application to Brussels’ airports

We study the problem of a city with access to two firms or subcentres (restaurants, airports) selling a differentiated product and/or offering a differentiated workplace. The first subcentre is easily congested (near city centre, access by road), the second less prone to congestion but further away. Both need to attract customers and employees and need to make profits to cover their fixed costs. This is an asymmetric duopoly game that can be solved for a Nash equilibrium in prices and wages. This solution involves excessive congestion for the nearby subcentre. Three stylised policies are studied to address this congestion. The first policy is to widen the congested road to the nearby subcentre. The second policy option is to add congestion pricing (or parking pricing etc.) for the congested subcentre. The third policy is to provide a direct subsidy to the remote subcentre so that it can reduce its price. We illustrate the theory using a numerical model applied to the two Brussels airports.duopoly, imperfect competition, congestion, general equilibrium, airport competition

Dundee Discussion Papers in Economics 215:Outsourcing versus FDI in oligopoly equilibrium

We consider the make-or-buy decision of oligopolistic firms in an industry in which final good production requires specialised inputs. Factor price considerations dictate that firms acquire the intermediate abroad, by either producing it in a wholly owned subsidiary or outsourcing it to a supplier who must make a relationship specific investment. Firms’ internationalisation mode depends on cost and strategic considerations. Crucially, asymmetric equilibria emerge, with firms choosing different modes of internationalisation, even when they are ex-ante identical. With ex-ante asymmetries, lower cost producers have a stronger incentive to vertically integrate (FDI), while higher cost firms are more likely to outsource

Asymmetric Duopoly in Space - what policies work?

In this paper we study the problem of a city with access to two subcentres selling a differentiated product. The first subcentre has low free flow transport costs but is easily congested (near city centre, access by road). The second one has higher free flow transport costs but is less prone to congestion (ample public transport capacity, parking etc.). Both subcentres need to attract customers and employees by offering prices and wages that are sufficiently attractive to cover their fixed costs. In the absence of any government regulation, there will be an asymmetric duopoly game that can be solved for a Nash equilibrium in prices and wages offered by the two subcentres. This solution is typically characterised by excessive congestion for the nearby subcentre. We study the welfare effects of a number of stylised policies by setting up a general model and illustrating the model using competition between airports as an example. The first stylised policy is to extend the congested road to subcentre 1. This policy will not necessarily lead to less congestion as more customers will be attracted by the lower transport costs. The second policy option is to add congestion pricing (or parking pricing etc.) for the congested subcentre. This will decrease its profit margin and attract more customers. The third policy is acceptable for politicians: providing a direct subsidy to the remote subcentre, reducing its marginal costs. This policy will again ease the congestion problem for the nearby subcentre but will do this in a very costly way.duopoly, imperfect competition, congestion, general equilibrium, airport competition
