Sensitivity and Stability Analysis in DEA: Some Recent Developments

This papersurveys recently developed analytical methods for studying thesensitivity of DEA results to variations in the data. The focusis on the stability of classification of DMUs (Decision MakingUnits) into efficient and inefficient performers. Early workon this topic concentrated on developing solution methods andalgorithms for conducting such analyses after it was noted thatstandard approaches for conducting sensitivity analyses in linearprogramming could not be used in DEA. However, some of the recentwork we cover has bypassed the need for such algorithms. Evolvingfrom early work that was confined to studying data variationsin only one input or output for only one DMU at a time, the newermethods described in this paper make it possible to determineranges within which all data may be varied for any DMU beforea reclassification from efficient to inefficient status (or vice versa) occurs. Other coverage involves recent extensionswhich include methods for determining ranges of data variationthat can be allowed when all data are varied simultaneously for all DMUs. An initial section delimits the topics to be covered.A final section suggests topics for further research.     

The harder they fall,the faster they rise: Approach and avoidance focus in narcissistic CEOs

Drawing on theoretical underpinnings of approach‐avoidance motivation and CEO narcissism, we provide a framework examining stronger approach focus (motivation towards desirable outcomes) and weaker avoidance focus (motivation away from undesirable outcomes) in narcissistic CEOs using a quasi‐natural experimental setting—the economic crisis beginning in 2007. Because highly narcissistic CEOs possess lower avoidance motivation in the precrisis period, their firms face greater declines in the onset of the crisis. However, their greater tendency towards approach motivation enables narcissistic CEOs to increase firm performance in the postcrisis period. While narcissistic CEOs are less likely to protect against potential shocks, they are adept at helping firms recover from such shocks. Using a sample of 392 CEOs representing 2,352 CEO firm‐years, we find support for the proposed framework. Copyright © 2013 John Wiley & Sons, Ltd.     

Regular Effective Demand Systems (REDS)

Empirical demand analysis is usually conducted on the basis of either ‘regularity’ or ‘flexibility’. This paper takes a middle ground between ‘regularity’ and ‘flexibility’, offering a compromise in the form of a new specification termed ‘REDS’.     

Popularizing a Management Accounting Idea: The Case of the Balanced Scorecard

We explore how the Balanced Scorecard (BSC), as a management accounting technique, was developed and marketed as a general management practice. Drawing on actor network theory (ANT), we analyze interviews with key actors associated with the BSC, insights gained from attending BSC training workshops, and other documentary evidence to construct a history of the BSC. Our historical analysis offers theoretical tools to understand how the various features of the accounting technique were translated and transformed, that is, shaped and solidified. This translation entailed processes of modification, labelling, framing, and specification of abstract categories and cause‐effect relations. We also examine the networks and associations that both shape the form of the BSC and mobilize the interests of various constituencies around it to produce what can be regarded as a global management technology. Finally, we highlight the strategies and actions used to maintain control of this technique through its continuous reinvention, and, by doing so, we emphasize the idea of strategic agency.     

Coordination and transfer

We study the ability of subjects to transfer principles between related coordination games. Subjects play a class of order statistic coordination games closely related to the well-known minimum (or weak-link) and median games (Van Huyck et al. in Am Econ Rev 80:234–248, 1990, Q J Econ 106(3):885–910, 1991). When subjects play a random sequence of games with differing order statistics, play is less sensitive to the order statistic than when a fixed order statistic is used throughout. This is consistent with the prediction of a simple learning model with transfer. If subjects play a series of similar stag hunt games, play converges to the payoff dominant equilibrium when a convention emerges, replicating the main result of Rankin et al. (Games Econ Behav 32:315–337, 2000). When these subjects subsequently play a random sequence of order statistic games, play is shifted towards the payoff dominant equilibrium relative to subjects without previous experience. The data is consistent with subjects absorbing a general principle, play of the payoff dominant equilibrium, and applying it in a new related setting.     

Seizing Opportunities: The Moderating Role of Managerial Characteristics on the Relationship between Opportunity‐Seeking and Innovation Efficacy in Small Businesses

We draw from regulatory focus theory to examine the relationship between a focus on opportunities through strategic orientation and entrepreneurial culture and managerial reports of innovation efficacy in small businesses. We propose that manager goals and behaviors moderate these relationships. Hypotheses were tested on a sample of 352 small employer firms. Findings support that strategic orientation positively associates with innovation efficacy and that this relationship is stronger under low managerial direction behaviors. Entrepreneurial culture positively associates with innovation efficacy when managers focus on profit and growth goals and under high managerial direction behaviors.     

Policy preferences of experts seeking to raise and stabilise farm incomes in the Eastern Gangetic Plains

Poverty is endemic in the highly populated Eastern Gangetic Plains where agriculture is critical to more than half the population. However, the mechanisms to support agriculture for development are contested. For example, some have advocated a strong role for government support and assistance due to market weaknesses, while others have promoted the need for more market-oriented approaches. We use an elicitation process focussed on expert policymaking communities, employing stated preference techniques to explore these options. Differences in perceptions about the effectiveness of policies and their delivery are reported between countries, while also empirically examining the influence of the respondents' organisational background. The results show support for policies that improve farmers' access to inputs, especially when delivered by private sector actors. The research provides an important contribution to the literature on policies for agricultural development.     

Optimal equity valuation using multiples: The number of comparable firms

We examine how the accuracy of a multiples-based valuation changes as the number of comparable firms used to estimate the valuation multiple increases. Our research is motivated by a contrast between the approach followed by practitioners, who typically use a small number of closely comparable firms, and the academic literature which often uses all firms in an industry. Using a simple selection rule based on growth rates, we find that using 10 closely comparable firms is as accurate on average as using the entire cross-section of firms in an industry. The loss of accuracy from using five comparable firms rather than 10 firms or the entire industry is not great.     

Exploring customer heterogeneity with a scale-extended latent class choice model: Experimental evidence drawn from urban water users

The search for improved water pricing is central to urban water reform in many countries. Establishing efficient water prices is notoriously difficult, not least because different customers have different demands for water and yet they are presently faced with a one-size-fits-all approach to pricing and service. This is especially challenging where water availability fluctuates widely, as is the case in many parts of Australia, because the impacts of exposure to episodic periods of scarcity can differ markedly. There is now substantial interest in the notion of ‘unbundling’ the water product to provide a better fit between customers' preferences and the level of service received. Following this trend, this study provides important insights into householders' willingness to pay for a range of flexible water options using a choice experiment. The paper reports a relatively underemployed extension to the latent class modelling framework to investigate preference heterogeneity towards urban water products, including purchasing services that involve the provision of environmental and amenity outcomes. The work adds to studies that use choice data to reveal heterogeneity while improving our understanding of household customers' demands. Overall, it also brings into focus questions about the future management of water in urban contexts.     

Rethinking Accounting,Accountability, and Accounting Regulation: Concerns about the Proposed Canadian Sustainability Standards Board*

This paper expands on a letter recently submitted by a group of Canadian business academics to the Independent Review Committee on Standard Setting in Canada (IRCSSC) in response to the committee's proposed Canadian Sustainability Standards Board. We highlight sections of the IRCSSC's Consultation Paper that we find problematic and draw on accounting and other research to explain why it fails to live up to its potential. Chief among the problems we identify is that the IRCSSC appears to be wedded to the same narrow, investor-based focus promoted by the International Sustainability Standard Board. We also draw attention to the rushed nature of the process, its exclusion of lay experts, the IRCSSC's ambiguous use of the term public interest, and its inattention to alternative understandings of value and the environment (including the people within it). Finally, we problematize the IRCSSC's sidestepping of the issues of power, culture, and conflict; its neglect of monitoring and enforcement; and its surprising disregard of the Global Reporting Initiative. Along with a number of suggestions for improving the process and its outcome, this paper also contributes to ongoing debates on standard setting and the question of whether accounting is currently equipped to provide the necessary tools for sustainability reporting.
