‘BIG DATA’, THE ‘INTERNET OF THINGS’ AND THE ‘INTERNET OF SIGNS’

This paper examines the relationship between so‐called ‘Big Data’, the ‘Internet of Things’ (the ‘Internet of People and Things,’ and the ‘Internet of Everything’), and the ‘Internet of Signs.’ In particular, we investigate how the ‘things’ in the ‘Internet of Things’ generate ‘Big Data’, and how both are used to generate semiotic ‘signs’. In addition, we analyse the importance of context in and the relationships between ‘Big Data’, the ‘Internet of Things’, and the ‘Internet of Signs’. Copyright © 2013 John Wiley & Sons, Ltd.     

Poverty or preference: what do ‘consensual deprivation indicators’ really mean?

Consensual deprivation indicators assume that there is a broad consensus on what goods/services families should be able to afford, and that an inability to afford those items can measure deprivation. Using data from two British surveys in 1999, this paper makes two arguments. First, there is only limited agreement about which items families should be able to afford. Secondly, different social groups are more (or less) likely to say the absence of a ‘necessity’ is due to choice. Families who cannot afford two or more ‘necessities’ invariably have a number of ‘nonnecessities’, often many. Their patterns of preferences (and spending) are not typical and they are choosing to buy other goods – through preference rather than poverty. Simply checking whether people lack items for any reason provides results empirically as reliable, but subject to similar criticisms.     

Consideration of the social context of auditors’ reliance on expert system output during evaluation of loan loss reserves

Auditors are accountable for judgments made within the social context of the accounting firm. Tetlock (1985) states that decision makers often use the acceptability heuristic to cope with accountability. According to this heuristic, individuals make decisions which they are reasonably confident will be acceptable by others to whom they are accountable. When auditors form judgments with the aid of expert system output, they must determine the appropriate level of reliance on the expert system output. Since the expert system output is based on the input of experts, auditors may decide the output is ‘acceptable‘ and overrely on the output. In addition, because of the conservative nature of the accounting firm, expert system output which is negative may be viewed as more acceptable than positive output leading to greater overreliance. The results indicate that auditors do overrely on expert system output and rely to a greater degree on output which is negative versus output which is positive.

Cross‐market spillovers with ‘volatility surprise’

This article adopts the asymmetric DCC with one exogenous variable (ADCCX) model developed by Vargas (2008), by updating the concept of ‘volatility surprise’ to capture cross-market relationships. Current methods for measuring spillovers do not focus on volatility interactions, and neglect cross-effects between the conditional variances. This paper aims to fill this gap. The dataset includes four aggregate indices representing equities, bonds, foreign exchange rates and commodities from 1983 to 2013. The results provide strong evidence of spillover effects coming from the ‘volatility surprise’ component across markets. Against the background of the recent financial crisis, the aim is to contribute to the literature on the interdependencies of financial markets, both in conditional means and (co)variances. In addition, asset management implications are derived.     

Firm Characteristics,Shareholder Sophistication and the Incidence of a ‘First Strike’ Under the ‘Two Strikes’ Rule in Australia

To restrain ‘excessive’ executive pay, Australia introduced new legislation in 2011, commonly known as the ‘two strikes’ rule. This rule has predictable consequences for publicly listed firms and their directors. In this study, we investigate which firm characteristics are associated with the incidence of a ‘first strike’ under the two strikes rule. We find that the incidence of a first strike is positively associated with higher levels of CEO pay, lower ownership concentration, smaller firm size, higher level of institutional ownership and CEO duality. Additional analysis suggests that shareholders fail to differentiate between CEO pay, which is related to the economic characteristics of a firm, and the pay that is not related to firm characteristics. This finding suggests that, unlike US shareholders, Australian shareholders do not appear to have a sophisticated understanding of CEO pay structure.     

Toward a better expert system for auditor going concern opinions using Bayesian network inflation factors

We develop an analytical model intended as the first stage in the development of expert systems to improve auditor knowledge in, and assist in the decision process of, Going Concern Opinions (“GCOs”). Our approach is consistent with a design science approach to developing information systems, resulting in an initial artifact, the mathematical model, which can, through iterative design science and behavioral research, inform a technology-based expert system. Based on Bayesian networks, our model provides insights about auditors’ revision, or inflation, of the probability to issue a GCO based on the interrelationship that forms with the incremental existence of one, two, or three publicly observable financial statement risk factors – net operating loss, negative cash flows from operations, and negative working capital. We calculate the revised probabilities using empirical data of GCOs from 2004 to 2015. Results reveal that the incremental relationship (one, two, or three factors present) effectively models expert auditors’ decisions to issue a GCO, and suggests the existence of these measurable inflation factors that represent situational and auditor-specific factors. We also find that Non-Big Four auditors inflate these factors differently than Big Four auditors to arrive at a decision to issue a GCO.     

SCOPE: a blackboard model-based decision support system for crude-oil trading

A complex decision problem dealing with crude-oil trading is hierarchically decomposed into multiple subproblems. A blackboard architecture for a Decision Support System (DSS) called SCOPE is developed in which the subproblems generated during the initial decision analysis can be mapped to relevant knowledge sources incorporating the most appropriate techniques for each. A prototype implementation of SCOPE-0, an expert system application using Knowledge Engineering Environment (KEE) for supporting the most critical subproblem—crude-oil evaluation—is presented. Some of the lessons learned from this research project, methodological issues, and promising future directions for DSS design are outlined. Copyright © 1999 John Wiley & Sons, Ltd.     

‘Knowledge Preservation in Accounting’: Does It Deserve to Be Preserved?

This is my third in a series of critical pieces on the accounting education field. The first, ‘What Accounting Can Learn from Legal Education’, was published in Issues in Accounting Education (Fall 1987) and dealt with the problems resulting from teaching accounting as a science. The second, ‘Wisdom or Widgets: Whither the School of Business?’ (Abacus, September 1988) dealt with the price we pay in our research for our obsession with quantitative methods. The current piece evaluates Robert Bricker's 1988 article in this journal.     

A comparative analysis of the evolution of a taxonomy for best practices: a case for ‘knowledge efficiency’

Taxonomies play an increasingly important role in knowledge management of business best practices, providing a basis by which to index, find and communicate knowledge. However, knowledge continues to evolve over time. As a result, taxonomies must also continue to evolve as organizations innovate and change. Reportedly, firms customize best‐practice taxonomies to meet their unique organization needs. Accordingly, we might expect organizations to generate dissimilar best‐practice taxonomies. However, taxonomies must also reflect the state of knowledge in the area being categorized, and thus are likely to be similar in many ways in different organizations. The purpose of this paper is to study how taxonomies change in different organizations and how they stay the same. In order to explain the parallels in organizational taxonomies, the notion of ‘knowledge artefact efficiency’ (or knowledge efficiency) is suggested to capture the concept that new knowledge is rapidly adopted by many organizations in their knowledge management systems.

IN-QUOTES: a knowledge-based system for supporting decision making in weakly structured domains

In complex and weakly structured domains, decision makers often employ multiple techniques, including quantitative modeling and reasoning from past experiences, to address the problem at hand. As such, there has been a call for more research on developing systems that merge problem-solving approaches, such as reasoning from past experiences, with other paradigms to provide support for both the unstructured and structured aspects of the decision-making process. Development of these systems is dependent on acquiring and modeling the knowledge and expertise inherent in the process and then representing and implementing it in an appropriate form. However, in weakly structured domains, knowledge acquisition may be better described as knowledge ‘co-creation’ in which the expert and system builder work together to understand the process and lend as much structure to it as possible. In this paper, we propose that the integration of principles drawn from the paradigms of case-base reasoning, expert systems, and object-oriented programming facilitates this process by providing a powerful approach to acquire and model knowledge in a weakly structured domain. We demonstrate this approach through the development of a system designed to assist a decision maker in the performance of a difficult, somewhat unstructured design and planning task. © 1998 John Wiley & Sons, Ltd.     

A Consulting Giant; a Disgruntled Client: A ‘Failed’ Attempt to Change Management Controls in a Public Sector Organisation

There has been very little research into management consulting interventions in public sector organisations, especially in emerging economies. This paper aims to fill this void by narrating the empirics of a consulting assignment carried out by a large international consulting firm in a Pakistani public sector organisation. The study found that consultants’ recommendations of ‘businesslike’ management controls, such as a modern performance measurement system and a ‘state‐of‐the‐art’ information system, were rejected outright by the client management. Employing a critical realist perspective that focuses on the structural conditions facing both the client and the consultants, and on the strategies adopted by both parties, the study aims to explain the empirics of the case. Through structural and strategic analysis, this paper aims to enhance our understanding of the dynamics of management consulting in public sector organisations, especially in emerging economies.     

A NOTE ON SOME ‘WEAK FORM’ TESTS OF CAPITAL MARKET EFFICIENCY IN NEW ZEALAND*

This paper reports the results of some experiments designed to test the ‘weak form’ efficiency of the New Zealand Stock Market The experiments were tests of serial correlation for various lags, and runs tests. The evidence suggests that the New Zealand market, at least as reflected in those securities tested, is essentially weak-form efficient     

‘MODERATION IN ALL THINGS’: INTERNATIONAL COMPARISONS OF GOVERNANCE QUALITY

Comparative measures of aspects of government in different countries are a rapidly growing industry. This paper offers a broad‐ranging critique of the state of the art. The two central questions are (a) How do currently available international measures of governance gain attention from non‐expert audiences, and (b), How understandable are they likely to be to these audiences?’ Findings from a range of relevant literature are brought to bear on three prominent sets of international measures, and conclusions are drawn.     

Narratives in managers’ corporate finance decisions

This article uses the extended case method to explore senior executives’ corporate finance decisions. We quantified firm’s finance practices using a mail survey, and then – to resolve puzzles in managers’ decision processes – conducted face‐to‐face interviews with chief finance officers of large listed firms. The interviews identified six themes as consistent influences on finance decisions: pressures imposed by clienteles; constraints on resources; risk management; heuristics; real options; and sustainability. We conclude that managers are logical and rational in their decisions, but employ a wider range of criteria than assumed in conventional finance theories.     

‘Bankruptcy tourism’ under the EC regulation on insolvency proceedings: A view from England and Wales

This article provides an account of the emergent phenomenon of ‘bankruptcy tourism’—forum shopping by debtors for favourable personal insolvency law—within the EU and with particular reference to England and Wales. After outlining the structural features of the European legal framework that make forum shopping for personal insolvency law possible, including the EC Regulation on Insolvency Proceedings and explaining why England and Wales in particular has proved to be an attractive ‘tourist’ destination, the article charts how the official receivers and the courts in England and Wales have sought to manage the influx of foreign bankruptcies in terms of legal principle and process drawing on two reported cases, Eichler and Mitterfellner. It will be seen that the institutional response in England and Wales has been twofold. First, the ‘problem’ of forum shopping debtors has been framed as a problem of policing the line between genuine and fictional relocations. Secondly, there are signs that the procedural onus on debtors to evidence their claim to English jurisdiction before a bankruptcy order is made has been increased, a move that can be interpreted as a form of institutional resistance designed to raise the barrier to entry. Having sought to illuminate the problems, costs and inconvenience associated with forum shopping from a practitioner standpoint, we explore the ‘good’ versus ‘bad’ forum shopping question and consider the scope for reform of the EC Regulation. Adopting a creditor perspective, we conclude provisionally that the Regulation could usefully be reformed to limit the scope for insolvent debtors to switch their COMI in anticipation of filing for bankruptcy.

The role of international banking in the ‘oil surplus’ adjustment process

In the rapidly changing and dramatically volatile oil market in which the balances of payments of the various countries are characterized by an unpreeendented variability, the role of international banks in the intermediations between countries, has been crucial. The stabilization function of the banking system which is instrumental in allowing a more rational oil production policy and investment policy has been since 1980 under considerable stress due to a decline of deposits. In this paper we shall first analyze the general framework of the problem and then the specific decision process of the banking system by emphasizing the differences between micro- and macroeconomic aspects.     

Transforming social sector auditing – they audited more,but scrutinized less

The legitimacy of audit technologies is inevitably linked to a knowledge base. Even though it has been pointed out that the agreements on how to measure and verify certain operations are only temporal, empirical studies on change in audit are rare. This paper reports a detailed empirical study of change in performance audit within social services in Sweden. The paper complements previous research since this paper is not about making new things auditable but about challenging existing technologies within a field. We observe how the new ‘sharp’ control‐based model – realized through measures of prioritizing, focusing and standardizing – was related to new demands on ‘facts’ about the audit object. The effect was that many things in this new situation became unauditable; they audited more, but actually scrutinized less. The paper also contributes to existing literature on the role of ‘sharp’ control‐based audit in the social sector. With a ‘soft’ and ‘fuzzy’ object, as is often the case in many parts of the public sector, it is difficult to produce hard, convincing evidence that holds true in different settings.     

Explanations for Not Having an Audit Committee in a ‘Comply or Explain’ Regime

We utilise the Australian ‘comply or explain’ corporate governance regime to examine the explanations given for not having an audit committee and whether these explanations are consistent with underlying firm characteristics. We hand‐collect explanations provided by firms, and find the most common explanations are that the firm or board size is too small or that the firm is insufficiently complex to justify an audit committee. Thus, the reasons that firms provide for not having an audit committee are focused on internal factors limiting their ability to supply an audit committee. As we find that these explanations are associated with lower total assets, smaller board size and lower leverage, they are consistent with underlying firm characteristics. Thus firms are not providing inconsistent or unrelated explanations as pretexts to avoid forming an audit committee. Documenting that the explanations given for non‐compliance are associated with related firm characteristics should be of interest to regulators and policy makers.     

A new statutory director’s duty for Australia — a ‘duty’ to be concerned about employee entitlements in the insolvent corporation

Australia has introduced legislation that is aimed at preventing a person from entering into agreements or conducting transactions with the intention of defeating the recovery of employee entitlements. It is essentially aimed at directors and their behaviour in the pre‐appointment period. This paper discusses the history leading up to such a legislative move and the likely benign impact now that the Corporations Act in Australia prohibits such behaviour. Further, the paper argues that mooted changes to the legislation giving employees a ‘maximum priority’ ahead of secured creditors is unnecessary. Copyright © 2003 John Wiley & Sons, Ltd.     

Are Auditors Professionally Skeptical? Evidence from Auditors’ Going‐Concern Opinions and Management Earnings Forecasts

We examine whether auditors exercise professional skepticism about management earnings forecasts when making going‐concern decisions. Using publicly issued management earnings forecasts as a proxy for earnings forecasts provided by managers to auditors, we find that management earnings forecasts are negatively associated with both auditors’ going‐concern opinions and subsequent bankruptcy. The weight auditors put on management forecasts in the going‐concern decision is not significantly different from the weight implied in the bankruptcy prediction model. Moreover, compared with the bankruptcy model, auditors assign a lower weight to management forecasts they perceive as being less credible, including those (1) issued by managers who issued optimistic forecasts in the previous two years, and (2) predicting high earnings increases or high earnings. Taken together, our evidence is consistent with auditors being professionally skeptical about management earnings forecasts when making going‐concern decisions.
