Book Reviews

The purpose of this short paper is to alert teachers of management accounting to a perceived inadequacy in the prevailing textbook treatment of a commonly taught and examined management accounting technique, the limiting factor rule, which, in many textbooks, functions as a preface to the exposition of linear programming. Having explained the manner in which the use of the limiting factor rule can lead to the discovery of the optimal production plan where there is just one constrained resource, it is common to assert the necessity of using linear programming in situations where there are multiple resource constraints. In this paper, the possibility of applying the limiting factor rule where more than one resource is constrained is explained more precisely than in existing textbooks. The significance of this discussion, it is suggested, lies as much in its contribution to intellectually sound exposition in textbooks as in its practical significance.     

Doing battle with short sellers: The conflicted role of blockholders in bear raids

If short sellers can destroy firm value by manipulating prices down, an informed blockholder has a powerful natural incentive to protect the value of his stake by trading against them. However, he also has a potentially conflicting incentive to use his information to generate trading profits. We show that a speculator can exploit this conflict and force the blockholder to buy a disproportionately large amount to prevent value destruction. This is costly for the blockholder because the trades must sometimes be executed at inflated prices. Given reasonable constraints on short sellers, a sufficiently large blockholder will have the incentive to absorb these losses and prevent a bear raid. However, conditions exist under which outside intervention may be warranted.     

A Model of the Relative Income Hypothesis

James Duesenberry's (1949) relative income hypothesis holds substantial empirical credibility, as well as a rich set of implications. Although present in the pages of leading economics journals, the hypothesis has become all but foreign to the blackboards of economics classrooms. To help reintegrate the concept into the undergraduate economics curriculum, the author constructs a model of the relative income hypothesis to present a few of its important properties and implications. Negative spending externalities, the effect of public provision taxes on wasteful spending races, and the Pareto implications of universal income growth are illustrated within a two-good consumption space as a method of introducing this rich literature to a greater number of introductory and intermediate economics students.     

Ricardian Equivalence and the Efficacy of Fiscal Policy in Australia

Events surrounding the global financial and economic crises of 2008 and 2009 have sparked a renewed interest in discretionary fiscal policy. This article considers whether private saving in Australia behaves in a manner that is consistent with Ricardian equivalence, thus mitigating the effects of fiscal policy, or conversely, if fiscal policy has some ability to influence the real economy. Results indicate that, while there is not a full Ricardian response to changes in the fiscal stance, there is some partial offsetting behaviour—implying that fiscal policy does elicit some (limited) impact on economic activity.     

Analysis of prospective airline mergers using a simulated annealing model

This paper examines the efficacy of a simulated annealing model of the US airline network in analyzing potential mergers between major airlines. The simulation performs satisfactorily in modeling the current hub-and-spoke system focusing on the effects on passenger routings, producer profits, and consumer welfare. In general, the simulated annealing model reasonably demonstrates the price and demand effects due to a merger of major carriers. While it cannot take into account all relevant information, such as labor union relationships and negotiating tactics, it can offers insight into the implications of airline mergers.     

Knowledge structures of prospectors,analyzers, and defenders: content,structure, stability,and performance

The managerial cognition perspective argues that managers operating in complex, dynamic environments develop knowledge structures that help them focus their attention, interpretation, and actions. We explore the content and structure of top managers' strategic knowledge structures by measuring differences in the level of attention they give in annual reports to strategic issues and themes that Miles and Snow used to describe their main strategic types. Twenty-one themes that form seven main factors describing managers' strategic cognition are identified, and these demonstrate reasonable fit with the Miles and Snow model. We show that expert raters can recognize these factors when they read annual reports that contain them. Cluster analysis is then used to identify groups of firms that share similar profiles on these strategic dimensions which are interpreted as examples of cognitive strategic groups. These groups show alignment with Miles and Snow's strategic types, are relatively stable over time, and differ in financial performance. The sample comprises 1,038 listed Australian firms between the years 1992 and 2003. Copyright © 2007 John Wiley & Sons, Ltd.     

Managing the Risks of Corporate Political Donations: A Utilitarian Perspective

This paper applies a utilitarian analysis to corporate political donations. Unlike the more common rights-based analyses, it is argued that the optimal policy is the one that best satisfies society’s rational preferences concerning donor influence, adequate financing, donor pressure and the cost of maintaining and enforcing the democratic system. This analysis suggests that a ban is best if it would be generally observed and sufficient financing from other sources is available, otherwise a donation cap is a better option. Further, lobbyists should be banned from donating small gifts and drafting bills for candidates. The impact of disclosure and other risk management mechanisms are also considered.     

Schlotzsky's gourmet deli franchise store#

This instructional case examines quantitative and qualitative information in the decision to acquire a franchise store of a Gourmet Deli chain. In particular, it illustrates to students how commonly requested quantitative information in practice, such as an income statement, needs to be tailored to the decision-making context. The case integrates and tests students' introductory understanding of income statements for managerial purposes, cost behaviour, break-even calculations, cost-benefit analysis, regression applications in management accounting, and corporate overhead cost allocations.     

The impact of securitization on the expansion of subprime credit

This paper investigates the relationship between securitization activity and the extension of subprime credit. The analysis is motivated by two sets of compelling empirical facts. First, the origination of subprime mortgages exploded between the years 2003 and 2005. Second, the securitization of subprime loans increased substantially over the same time period, driven primarily by the five largest independent broker/dealer investment banks. We argue that the relative shift in the securitization activity of investment banks was driven by forces exogenous to factors impacting lending decisions in the primary mortgage market and resulted in lower ZIP code denial rates, higher subprime origination rates, and higher subsequent default rates. Consistent with recent findings in the literature, we provide evidence that the increased securitization activity of investment banks reduced lenders' incentives to carefully screen borrowers.
