Appraising the precautionary principle – a decision analysis perspective

The public and regulators are naturally concerned about any decision that has uncertain but potentially serious health and environmental consequences. When facing such decisions, some individuals say we should resolve significant uncertainties before taking expensive action that may be unnecessary. Others support the precautionary principle, which says that policy makers should err on the side of caution by acting now to avoid or limit potentially detrimental consequences. This paper appraises the precautionary principle from a perspective decision analytic point of view. We argue that neither the 'resolve uncertainties before taking action' nor the 'act now on the side of caution' are appropriate as general policies for all environmental decision problems. Instead, we conclude that policy makers need to conduct sound, in-depth analyses to resolve the pros and cons of acting now versus conducting more research on a case-by-case basis.     

The precautionary principle: an 'unprincipled' approach to biotechnology regulation

A tenet of administrative law, particularly in the United States, is that regulators must base their decisions on 'intelligible principles' to provide consistency, predictability, transparency and accountability. The precautionary principle, which purports to provide a new decision rule for making environmental decisions under conditions of uncertainty, fails to provide such an intelligible principle for making decisions. The precautionary principle is ambiguous on the use of the two major criteria currently used to make environmental decisions - significant risk and cost-benefit balancing - yet offers no new specific decision criteria in their place. The second fundamental problem with the precautionary principle is that it is based on the unsubstantiated premise that the current regulatory system is insufficiently protective. The current system already tends to err on the side of the safety, as it should, but the relevant question is just how precautious should we be? As illustrated by the example of genetically modified organisms, the prudent level of precaution depends on factors such as the magnitude, distribution and uncertainty of risks, the extent of exposure, and the trade-offs and lost benefits in foregoing the risk. These are precisely the factors that are considered under the current risk-based approach, which the precautionary principle seeks to replace.     

Comparing precaution in the United States and Europe

The regulation of health and environmental risks has generated transatlantic controversy concerning precaution and the precautionary principle (PP). Conventional wisdom sees the European Union endorsing the PP and proactively regulating uncertain risks, while the United States opposes the PP and waits for evidence of harm before regulating. Without favouring either approach, this paper critically analyses the conventional depiction of transatlantic divergence. First, it reviews several different versions of the PP and their different implications. Second, it broadens the transatlantic comparison of precaution beyond the typical focus on single-risk examples, such as genetically modified foods. Through case studies, including hormones in beef and milk production and mad cow disease in beef and in blood donations, as well as reference to a wider array of risks, the paper demonstrates that relative precaution varies enormously. Sometimes the EU is more precautionary than the US (such as regarding hormones in beef), while sometimes the US is more precautionary than the EU (such as regarding mad cow disease in blood). Thus, neither the EU nor the US can claim to be categorically 'more precautionary' than the other. The real pattern is complex and risk-specific. Third, the paper seeks explanations for this complex pattern in five sets of hypotheses: optimal tailoring on the merits, political systems, risk perceptions, trade protectionism, and legal systems. None of these hypotheses fully explains the observed complex pattern of relative transatlantic precaution. The paper concludes that differences in relative precaution depend more on the context of the particular risk than on broad differences in national regulatory regimes.

The decision relevance and timeliness of accounting earnings in Saudi Arabia

This study examines the decision relevance and timeliness of accounting earnings in Saudi Arabia during the 1995-1999 sample period. The empirical results suggest that the publication of accounting earnings does not cause significant revision to the market assessment of future cash flows of Saudi firms. On the other hand, it appears that the publication of accounting earnings leads individual investors to revise their security holdings. However, this evidence is limited to cases where firms reported profit. The empirical results further suggest that earnings are timely in terms of their association with security returns and that increasing the measurement interval significantly improves this association. The tests also show that positive and negative earnings have differential implications for the timeliness of accounting earnings. Further tests show that this evidence is not consistent with the loss liquidation argument [J. Account. Econ. 20 (1995) 125] and, potentially, may reflect the lack of tax incentives to liquidate investments in loss firms. Finally, the results show that Saudi managers do not incorporate economic losses into accounting earnings on a timely basis which may reflect reduced market demand for accounting information, low levels of public debt, low expected litigation costs, and weak monitoring by analysts and other stakeholders.     

The effect of a decision aid on risk aversion in capital investment decisions

In this study we examine whether a decision aid is an effective means of reducing risk aversion within a capital investment decision context, and under what conditions. Participating in the experiment were 78 working adults (mid management) with a mean age 30 and enrolled in a leading U.S. MBA program. We predict and find that a decision aid will be most effective among individuals intolerance of ambiguity and exhibiting high negative affect.

Bounds for Ratios of Posterior Expectations: Applications in the Collective Risk Model

This paper considers the collective risk model for the insurance claims process. We will adopt a Bayesian point of view, where uncertainty concerning the specification of the prior distribution is a common question. The robust Bayesian approach uses a class of prior distributions which model uncertainty about the prior, instead of a single distribution. Relatively little research has dealt with robustness with respect to ratios of posterior expectations as occurs with the Esscher and Variance premium principles. Appropriate techniques are developed in this paper to solve this problem using the k -contamination class in the collective risk model.

Cue usage in financial statement fraud risk assessments: effects of technical knowledge and decision aid use

This paper investigates the effects of technical knowledge and decision aid use on financial statement fraud risk assessments made by directors and students. More extreme fraud risk assessments are made when participants identify and process larger (smaller) numbers of diagnostic (non‐diagnostic) factors, with technical knowledge driving diagnostic factor identification. Significant decision aid‐technical knowledge effects are also found; decision aid use has a detrimental effect on high‐knowledge directors while improving performance in inexperienced, low‐knowledge students. These results suggest that although decision aids can afford gains in performance in inexperienced users, they can have unintended and/or paradoxical behavioural effects on experienced users.     

The effect of experience and complexity on order and recency bias in decision making by professional accountants

Recently, questions have been raised regarding the impact of experience on the susceptibility of professional accountants to judgment bias—particularly order and recency biases as predicted in the Belief‐Adjustment Model. The Belief‐Adjustment Model predicts recency effects will always exist in complex decision domains (regardless of experience). Complexity is defined within the model as a function of task familiarity and information load. The prior studies on experience and bias in accounting domains have focused on varying task familiarity and have found that task familiarity can mitigate order/recency bias. In this study, complexity is operationalised through heavy information load (a condition more consistent with professional accounting environments) while maintaining a high level of task familiarity. Two experiments were conducted. The first experiment utilised a going concern decision using highly experienced partners and managers. The second experiment was conducted in the insolvency domain and used 87 experienced insolvency practitioners. The results indicate that experience does not mitigate order/recency bias under conditions of heavy information load.     

An analysis of the first ten volumes of research in Accounting, Business and Financial History

Although numerous studies have focused upon the publishing patterns of leading academic accounting journals, the area of accounting history has largely been neglected. This paper uses standard content and citation techniques to analyse the 155 articles published in the first ten volumes of Accounting, Business and Financial History across the period 1990 to 2000. It highlights the leading individual and institutional contributors to ABFH, the major foci of their studies and the journals, articles and scholars exerting the greatest influence upon ABFH authors.     

Change analysis of a dynamic copula for measuring dependence in multivariate financial data

This paper proposes a new approach to measure dependencies in multivariate financial data. Data in finance and insurance often cover a long time period. Therefore, the economic factors may induce some changes within the dependence structure. Recently, two methods have been proposed using copulas to analyse such changes. The first approach investigates changes within the parameters of the copula. The second determines the sequence of copulas using moving windows. In this paper we take into account the non-stationarity of the data and analyse the impact of (1) time-varying parameters for a copula family, and (2) the sequence of copulas, on the computations of the VaR and ES measures. We propose tests based on conditional copulas and the goodness-of-fit to decide the type of change, and further give the corresponding change analysis. We illustrate our approach using the Standard & Poor 500 and Nasdaq indices in order to compute risk measures using the two previous methods.
