On the constitution of audit committee effectiveness

Pressures to perform and be effective are significantly influential within contemporary society, including within the realm of corporate boards of directors and audit committees. This paper adopts a social constructivist approach to better understand the process by which meanings regarding audit committee effectiveness are internally developed and sustained, within the small group of people who attend audit committee meetings. We conducted the investigation through interviews in three large Canadian public corporations listed on the Toronto Stock Exchange.     

Appraising and Evaluating PFI for NHS Hospitals

This paper explores the use of appraisal in the development of proposals to use private finance to provide acute hospitals under the Private Finance Initiative (PFI). It addresses the extent to which value for money (VFM) and affordability (which must be satisfied to enable a scheme to be approved) are demonstrated in the documents prepared by hospital Trusts. It identifies a number of issues (such as the transfer of risk and the development of public sector comparators) that pose new problems for investment appraisal, which are specific to its application to PFI.     

Improving lattice schemes through bias reduction

Lattice schemes for option pricing, such as tree or grid/partial differential equation (p.d.e.) methods, are usually designed as a discrete version of an underlying continuous model of stock prices. The parameters of such schemes are chosen so that the discrete version “best” matches the continuous one. Only in the limit does the lattice option price model converge to the continuous one. Otherwise, a discretization bias remains. A simple modification of lattice schemes which reduces the discretization bias is proposed. The modification can, in theory, be applied to any lattice scheme. The main idea is to adjust the lattice parameters in such a way that the option price bias, not the stock price bias, is minimized. European options are used, for which the option price bias can be evaluated precisely, as a template to modify and improve American option methods. A numerical study is provided. © 2006 Wiley Periodicals, Inc. Jrl Fut Mark 26:733–757, 2006     

The ideology of class and tourism confronting the discourse of advertising

Starting from Baudrillard's analysis of the ideological character inherent in all consumption, touristic consumption, for many reasons ,has a special place in this social semantic. Here, advertising plays an important if not essential role because tourism is a product consumed outside of normal time and daily social space. Therefore the social semantic asserts itselfless through the product itself than through its representation: the discourse of advertising. But advertising discourse is plural, each form having its own ideology, competing with others. Behind the commercial competition lies a competition of social classes, but with a new typology, no longer based on the capital/favor relationship. Four ideological models are analyzed and illustrated with their advertising messages: the traditional model, the clerical/executive model, the youth model, and the “intellectual class” model.     

Global and political strategies in deregulated industries: the asymmetric behaviors of former monopolies

In deregulated industries former monopolies often adopt asymmetric behaviors: these firms impede the entry of foreign competitors in their home market, especially using defensive political strategies, and, at the same time, aggressively develop international strategies in foreign markets. To account for this behavior, I develop a game theoretic model involving three players: the former monopoly, its home government, and the host government of the country into which the firm wants to enter. I show first that there are in fact different asymmetric strategies that former monopolies can use in such a setting, and that a global strategy cannot always be implemented by those firms because of cooperation issues between the two governments. I also study the conditions under which these issues can be solved and show that this can happen only when the firm develops a political strategy that integrates both defensive and offensive activities. Overall, this paper therefore argues that asymmetric strategies are not always adopted to maintain monopoly rents but are also dictated by the nature of the international relationships between the governments involved.
