Metagame analysis of competitive strategy

The need for effective competitive strategy planning for a firm's survival and growth has long been recognized to be important. The identification and selection of good, or robust, market strategies must be based on the anticipation of the likely strategies of significant competitors, who should ideally be visualized as undergoing a similar process of assessing their own and other's goals and probable strategies. This paper reviews and evaluates the traditional economic and game theoretic approaches to competitive strategy analysis and presents an application of metagame analysis—an approach which has not previously been used in the strategic business environment. This approach, which appears to have some significant advantages over both economic and game theoretic approaches has been utilized and evaluated in a business firm (Dutta and King, forthcoming). An illustration of its use, which is based on a real-world application, is discussed.     

A point optimal test for heteroscedastic disturbances

A new test for additive heteroscedasticity in the disturbances of the linear regression model is proposed. Power functions of various forms of the new test are compared empirically with those of currently favoured tests for a range of heteroscedastic models. The results highlight the power advantage of a test which is MP1 at a central point in the alternative hypothesis parameter space. The main conclusion is that the recommended version of the new test is generally more powerful than existing tests against medium and severe heteroscedasticity, whereas the King and Szroeter tests perform better against weak heteroscedasticity.     

Sustainability of Tourism Development in Macao,China

To maximize the benefits to stakeholders in Macao, the sustainability of Macao tourism was examined by assessing the economic, socio‐cultural and environmental impacts of tourism, visitor satisfaction and the level of community involvement in local tourism planning from 2002 to 2009, through the use of primary and secondary data. The results revealed that tourism did bring both positive and negative impacts to the community. Visitor satisfaction was found to be moderate. Channels for community participation in local tourism development were also lacking. The paper suggests that for sustainable tourism development, Macao needs to diversify away from its casino industry, to speed up the construction of the public transport system and to keep monitoring the environmental conditions, the students' drop‐out and crime rate and the locals' quality of life. More importantly, a master plan for its tourism development integrating all the key stakeholders' interests is urgently required. Copyright © 2011 John Wiley & Sons, Ltd.     

Hedge funds and financial stability: Regulating prime brokers will mitigate systemic risks

We review key characteristics of the hedge fund industry, and identify conditions under which this sector can pose a threat to financial stability. Direct regulation of hedge funds that increases transparency does not appear feasible, may create a moral-hazard problem, and may reduce market liquidity. Indirect regulation by prime brokers and market discipline by creditors, counterparties, and investors have been effective in limiting the risks from the hedge fund sector. To reduce systemic risks, more regulation of prime brokers is warranted to avoid competitive dynamics from undermining counterparty risk management practices.     

Competitive Neutrality in Access Pricing

This article examines the notion of competitive neutrality when setting access prices for vertically integrated bottleneck networks. In contrast to the claims of regulated firms (for example, Telstra), it is not possible to argue that access charges that involve unit prices in excess of short‐run marginal cost reflect competitive neutrality. That is, we demonstrate that in general models of downstream oligopoly, upstream prices that differ from marginal cost are not competitively neutral in the sense of placing integrated and non‐integrated firms on an equal basis.
