Auditing,Reasoning Systems,Reporting Frameworks,and Accounting Policy Risk: A Response to Alexander

This response to Alexander (2010 ) clarifies the approach taken in Smieliauskas et al. (2008 ). Here we elaborate further on the significance of the accounting risk concept for fairness of presentation in financial reporting. In the process we show how Alexander's potentially important concept of accounting policy risk can be made operational via the concept of accounting risk.     

Capital and Risk Revisited: A Structural Equation Model Approach for Life Insurers

The role of risk in the capital structure decision of firms is a vast topic in finance. Commonly, models of the interrelationship between risk and capital enumerate as many risk factors as possible by appropriate proxies, with the goal of detailing their individual effects. In this study of the life insurance industry for 1994 through 2000, we take a broader, holistic view of enterprise risk, identifying two groups of insurer risk factors that arise from the major activities of life insurers: investing and underwriting. We call the group of risk factors associated with investing asset risk, and the group associated with underwriting product risk. After specifying other important determinants of capital structure as controls, we allow all other risk factors to find expression in residual error. Within this framework, our focus is to compare two candidate measures for the role of proxy for asset‐related risks. One measure, called regulatory asset risk (RAR), derives from the regulatory tradition of concern with solvency and is related to the C‐1 component of risk‐based capital. The other measure, called opportunity asset risk (OAR), is motivated by traditional finance concerns with market risk and reflects volatility of returns. Product‐related risks are proxied by underwriting exposures in different product lines. We employ structural equation modeling (SEM), which uses longitudinal factor analysis. SEM is an innovative technique for such studies, in dealing effectively with multiple structural equations, autocorrelated panel data, unobserved underlying factors, and other issues that are not simultaneously addressed in other methodologies. We find that RAR and OAR are not equivalent proxies for asset risks. Although overlapping to some extent, each illuminates different aspects of the asset risk–capital interrelationship. In particular, RAR does not seem to affect the capital structure decision of small firms, although OAR does. We interpret this to suggest that small firms as a whole are not as sensitive in their capital decisions to the proxy of regulatory concerns as to the proxy of market opportunity. This contrasts with large insurers, for whom both RAR and OAR have significant effects on capital that comport with the finite risk hypothesis. More detailed analysis suggests that the lack of effect of RAR for small insurers may result from RAR's proxying some factors that induce finite risk for part of the small insurer sample, and other factors that favor the excessive risk hypothesis.     

More on Properness: The Case of Mean-Variance Preferences

This paper focuses on the situations where individuals with mean-variance preferences add independent risks to an already risky situation. Pratt and Zeckhauser (Econometrica, 55, 143–154, 1987) define a concept called proper risk aversion in the expected utility framework to describe the situation where an undesirable risk can never be made desirable by the presence of an independent undesirable risk. The assumption of mean-variance preferences allows us to study proper risk aversion in an intuitive manner. The paper presents an economic interpretation for the quasi-concavity of a utility function derived over mean and variance. The main result of the paper says that quasi-concavity plus decreasing risk aversion is equivalent to proper risk aversion.     

An Intertemporal International Asset Pricing Model: Theory and Empirical Evidence

We extend Campbell's (1993) model to develop an intertemporal international asset pricing model (IAPM). We show that the expected international asset return is determined by a weighted average of market risk, market hedging risk, exchange rate risk and exchange rate hedging risk. These weights sum up to one. Our model explicitly separates hedging against changes in the investment opportunity set from hedging against exchange rate changes as well as exchange rate risk from intertemporal hedging risk. A test of the conditional version of our intertemporal IAPM using a multivariate GARCH process supports the asset pricing model. We find that the exchange rate risk is important for pricing international equity returns and it is much more important than intertemporal hedging risk.     

Measuring Longevity Risk: An Application to the Royal Canadian Mounted Police Pension Plan

An employer that sets up a defined benefit pension plan promises to periodically pay a certain sum to each participant starting at some future date and continuing until death. Although both the future beneficiary and the employer can be asked to finance the plan throughout the beneficiary's career, any shortcoming of funds in the future is often the employer's responsibility. It is therefore essential for the employer to be able to predict with a high degree of confidence the total amount that will be required to cover its future pension obligations. Applying mortality forecasting models to the case of the Royal Canadian Mounted Police pension plan, we illustrate the importance of mortality forecasting to value a pension fund's actuarial liabilities. As future survival rates are uncertain, pensioners may live longer than expected. We find that such longevity risk represents approximately 2.8 percent of the total liability ascribable to retired pensioners (as measured by the relative value at risk at the 95th percentile) and 2.5 percent of the total liabilities ascribable to current regular contributors. Longevity risk compounds the model risk associated with not knowing what is the true mortality model, and we estimate that model risk represents approximately 3.2 percent of total liabilities. The compounded longevity risk therefore represents almost 6 percent of the pension plan's total liabilities.     

Time Period and Risk Measures in the General Risk Equation

In an earlier paper, a general risk equation, applicable to all non growth systems, and inclusive of financial systems, was derived. It related expected throughput capacity of any system to both system resources and positive risk of loss of throughput capacity. Two risk measures were required, a new MEL‐risk measure, and the conventional standard‐deviation risk measure.

In this paper we show that the two apparently distinct risk measures are intimately related, and that which one is appropriate depends merely on the time period over which the risk is calculated. We show, ultimately by application of the Central Limit Theorem, that if we merely sufficiently alter the time period, at some point the need for one measure will transition into the need for the other, without any change in the underlying physical system.

This leads to a comprehensive risk measure that defaults to either the MEL‐risk measure, or standard‐deviation measure, depending not on the physical system, but merely on the time period over which the risk is calculated.     

The Causal Impact of Media in Financial Markets

Disentangling the causal impact of media reporting from the impact of the events being reported is challenging. We solve this problem by comparing the behaviors of investors with access to different media coverage of the same information event. We use zip codes to identify 19 mutually exclusive trading regions corresponding with large U.S. cities. For all earnings announcements of S&P 500 Index firms, we find that local media coverage strongly predicts local trading, after controlling for earnings, investor, and newspaper characteristics. Moreover, local trading is strongly related to the timing of local reporting, a particular challenge to nonmedia explanations.     

Measuring potential market risk

We argue herein that there is a fundamental and an important difference between the market risk and the potential market risk in financial markets. We also argue that the spectrum of smooth Lyapunov exponents can be used in (λ,σ²)-analysis, which is a method to measure and monitor these risks. The reason is that these exponents focus on the stability properties (λ) of the stochastic dynamic system generating asset returns, while more traditional risk measures such as value-at-risk are concerned with the distribution of asset returns (σ²).     

Risk association: towards a linguistically informed framework for analysing risk in discourse

This article addresses a fundamental feature of risk discourse, namely, risk association, defined as the process whereby an agent establishes a connection between something, x, and the notion of risk. In addition, risk association can be defined as the result of such a process, i.e. an established connection between x and risk. A special case of risk association is when x is linked to harmful properties and thus is represented as a risk. Although fundamental to any analysis of socio-cognitive attention to risks, the process of risk association is often taken for granted in risk research. A layered model of risk association is presented taking linguistic practices, i.e. the use of words, as the point of departure. Accordingly, there are both central and more peripheral means of risk association. The central means include the morpheme ‘risk’. More peripheral means of risk association are close synonyms and antonyms of risk (e.g. ‘hazard’, ‘danger’, ‘safety’ and ‘security’) and other related words (e.g. ‘crisis’, ‘protection’ and ‘threat’). For an illustration, the model is applied to an empirical example: the instructions for Swedish government agencies. The example illustrates how the exact vocabulary considered for operationalization in analysis has important consequences for the conclusions that follow with respect to the extent to which government agencies are associated with risk.     

Deterministic criteria for the absence of arbitrage in?one-dimensional diffusion models

We obtain a deterministic characterisation of the no free lunch with vanishing risk, the no generalised arbitrage and the no relative arbitrage conditions in the one-dimensional diffusion setting and examine how these notions of no-arbitrage relate to each other.     

Exploring Comparative Ratings and Constituent Facets of Public Trust in Risk Regulatory Bodies and Related Stakeholder Groups

This paper reports on two comparative ranking tasks performed by a sample of the British citizens (N = 304). The first was designed to compare levels of relative trust vested in a sample of UK risk regulatory bodies and associated stakeholder groups. The second sought to elicit a ranking of a range of previously identified facets of social trust referenced to their desirability as attributes of a government funded risk regulatory body. The ranking tasks were embedded within a broader programme of research focused on “Evaluating public understandings of and trust in the Health and Safety Executive” (Pidgeon et al., 2003). It is argued that deriving rankings of multi‐faceted phenomena using the method of paired comparisons offers a more robust approach to rating social trust entities than the direct ranking techniques used in previous studies in this area. Results are discussed with reference to qualitative findings from the broader programme of work on public trust in HSE (Pidgeon et al., 2003) and the wider literature on public trust in risk regulation.     

Leveraged investor disclosures and concentrations of risk

We analyze a model where investors (e.g., hedge funds) need to borrow from lenders with heterogeneous risk-exposures and risk-management motives. Investors may obtain advantageous terms of borrowing by disclosing their investment strategy, thereby revealing its correlation to the lender's existing risk exposure. Investors risk being “front-run” by their lender if they disclose, however. We show that in the presence of front-running, the “unraveling” result of full disclosure may not hold. In addition, disclosure regulation results in a loss of welfare since investors compelled to disclose will mitigate front-running by choosing a lender with sufficiently high correlation, thus exacerbating concentrations of risk.     

From objective to constituted risk: an alternative approach to safety in strategic technological innovation in the European Union

Safety is a legitimate means of limiting technological innovation in our societies. However, the potential socio-economic impact of curtailing techno-industrial progress on the grounds of safety means that risk governance policies tend to restrict the range of legitimate approaches to safety on the principle that it can only be discussed in the frame of an allegedly objective scientific representation of risk. In European risk governance, socio-economic factors such as the underlying innovation rationales and goals are not openly considered to be related to the constitution of safety, but tend largely to be treated as factors of subjective reaction towards risk and technology. This paper seeks to overcome that approach by proposing a ‘constitutive’ understanding of how risk and socio-economic factors and dynamics relate, focusing in particular on the ‘safe and responsible’ development of nanotechnology in the European Union (EU). I argue that risk is constituted according to socio-economic considerations, and that the controllability of the environmental and health risks of nanotechnology in the EU is assumed on principle in the very strong institutional commitment to the industrial exploitation of nanotechnology R&D. Using a constitutive approach, we may legitimately conceive a broader set of potential safety scenarios, while at the same time highlighting major obstacles to implementing more critical constitutions of techno-industrial risk in the framework of a highly competitive knowledge-based global economy.     

UK Evidence on the Characteristics versus Covariance Debate

We evaluate the Fama–French three‐factor model in the UK using the approach of Daniel and Titman (1997) to determine whether characteristics or covariance risk better explains the size and value premiums. Across all three factors, we find that return premiums bear little relationship to the corresponding loadings. We show that small and value stocks earn higher returns irrespective of their return covariance. Our study contributes to the existing literature by reporting original findings on the Fama–French three‐factor model in the UK and by reporting results that complement existing evidence from similar studies in the USA and Japan.     

Calibration to American options: numerical investigation of the de-Americanization method

American options are the reference instruments for the model calibration of a large and important class of single stocks. For this task, a fast and accurate pricing algorithm is indispensable. The literature mainly discusses pricing methods for American options that are based on Monte Carlo, tree and partial differential equation methods. We present an alternative approach that has become popular under the name de-Americanization in the financial industry. The method is easy to implement and enjoys fast run-times (compared to a direct calibration to American options). Since it is based on ad hoc simplifications, however, theoretical results guaranteeing reliability are not available. To quantify the resulting methodological risk, we empirically test the performance of the de-Americanization method for calibration. We classify the scenarios in which de-Americanization performs very well. However, we also identify the cases where de-Americanization oversimplifies and can result in large errors.     

The Role and Current Status of IFRS in the Completion of National Accounting Rules – Evidence from Sweden

Abstract

In this paper, the influence of IFRS on Swedish national accounting rules is analyzed. The lawmaker’s and standard setters’ response to EU Accounting Directive 2013/34/EU is studied, as well as the use of IFRS in enforcement. The conclusion is that IFRS have a strong position and legitimacy in Swedish financial reporting.     

Science and proven experience: a Swedish variety of evidence-based medicine and a way to better risk analysis?

A key question for evidence-based medicine (EBM) is how best to model the way in which EBM should ‘[integrate] individual clinical expertise and the best external evidence’. We argue that the formulations and models available in the literature today are modest variations on a common theme and face very similar problems when it comes to risk analysis, which is here understood as a decision procedure comprising a factual assessment of risk, the risk assessment, and the decision what to do based on this assessment, the risk management. Both the early and updated models of evidence-based clinical decisions presented in the writings of Haynes, Devereaux and Guyatt assume that EBM consists of, among other things, evidence from clinical research together with information about patients’ values and clinical expertise. On this A-view, EBM describes all that goes on in a specific justifiable medical decision. There is, however, an alternative interpretation of EBM, the B-view, in which EBM describes just one component of the decision situation (a component usually based on evidence from clinical research) and in which, together with other types of evidence, EBM leads to a justifiable clincial decision but does not describe the decision itself. This B-view is inspired by a 100-years older version of EBM, a Swedish standard requiring medical decision-making, professional risk-taking and practice to be in accordance with ‘science and proven experience’ (VBE). In the paper, we outline how the Swedish concept leads to an improved understanding of the way in which scientific evidence and clinical experience can and cannot be integrated in light of EBM. How scientific evidence and clinical experience is integrated influences both the way we do risk assessment and risk management. In addition, the paper sketches the as yet unexplored historical background to VBE and EBM.     

Is the social representation of nanotechnology anchored in that of GMOs?

The use of nanotechnology (devices/materials composed of parts less than 10 nanometres) in the development of new products is rapidly expanding. Industrialists and decision-makers consider nanotechnology to be the next industrial revolution, but fear they risk the same resistance to nanotechnology that their counterparts experienced with genetically modified organisms (GMOs). Although risk perception studies have shown that perceived risk of GMOs is quite high compared to that related to nanotechnology, no study to date has explored a potential direct social representation link between the two. The present study aims to fill that gap by comparing the social representations of nanotechnology and GMOs among a population of non-experts. This study was conducted with 282 students in human and social sciences and natural sciences. Using a free association task with the inductive words ‘nanotechnology’ and ‘GMO (genetically modified organism)’, we identified the existing social representations of the two based on a structural approach. While the representation of GMOs is objectified in the field of agriculture, objectification for nanotechnology seems to still be lacking, although its possible objectification likely lies in computing and robotics. Our calculation of the rate of similarity of associative words with nanotechnology and GMOs indicated no present, direct link between their social representations. We discuss the possible evolution of the social representation of nanotechnology over time.     

Incentives and financial crises: Microfounded macroprudential regulation

We provide a micro-based rationale for macroprudential capital regulation of financial intermediaries (banks) by developing a model in which bankers can privately undertake a costly effort and reduce the probability of adverse shocks to their asset holdings that force liquidation (deterioration risk). A decline in the fundamental risk of assets ameliorates funding conditions, boosting the banks’ ability to expand their balance sheets. In principle, a higher continuation value would improve incentives to put effort. However, the rise in asset demand and prices also increases the payoff in liquidation, eventually reducing the equilibrium optimal effort. Poor incentives impose socially inefficient liquidation and can be corrected through a regulatory capital requirement. We show that the requirement should be high when fundamental risk is low. Therefore, the model suggests a theoretical foundation for macroprudential regulation and the countercyclical capital buffer of Basel III.     

Strategies to create risk awareness and legitimacy: the Swedish climate campaign

Social means of risk regulation often only arise in response to media attention and public opinion. In contrast, in the case of climate change, the Swedish government proactively launched a public information campaign to promote public awareness and knowledge of the risks associated with climate change, with the explicit objective of promoting acceptance of public means of reducing greenhouse gas emissions. This paper analyses the framing of climate change in the Swedish climate campaign and its communication strategy. What was the message of the campaign narrative? What did it imply concerning the causes, effects, and management of and responsibility for climate change? What means were used to communicate the risks of climate change? The paper analyses the campaign narrative, its references to various affective images of climate change, and the various storytelling techniques it used. It concludes that the Swedish climate campaign relied on a unidirectional view of risk communication and proffered a narrative containing inconsistencies and ambivalence. The analysis demonstrates that despite a thoroughly worked‐out strategy, a well‐defined message, and the intention to speak clearly, a complex problem such as climate change cannot easily be transformed into a single, coherent story.
