Methods that are typically used to examine individual differences in risk attitudes (e.g. lotteries, dilemmas, questionnaires) require participants to explicitly declare their willingness to take risk. Therefore, they may be biased by the need for self-presentation or situational characteristics such as time pressure and cognitive constraints that lead to more spontaneous and automatic processing of risk-related information. The aim of this study was to construct an indirect measure of risk attitudes that is free of these methodological limitations. The method based on the Implicit Association Test shows high internal reliability and satisfactory stability over time. It correlates moderately with different explicit measures of risk attitudes that are related to sensation seeking. Finally, it is characterized by a high predictive power. Adding the implicit measure to the set of independent variables representing declarative evaluations of risk attitudes significantly improved the model predicting risky real-life behavior. We argue that the indirect assessment of risk attitudes presented in this paper may be used as an universal measure of people’s risk propensity that is free of biases related to self-presentation and situational factors.  相似文献

This paper presents a heterogeneous agents model of the foreign exchange market in which agents’ risk attitudes vary over time due to psychological factors emphasized in prospect theory. We find that psychological component and risk-profit elasticity play significant roles in exchange rate expectations formation and investment behavior. Although all agents show more risk-averse after the crisis, the extent to which their risk attitude responds to the crisis varies due to heterogeneous forecasting rules as well as the changes of trading environment and central bank intervention. Moreover, time-varying risk attitudes can help explain the forward premium puzzle. These findings have implications for the exchange rate expectation formation theories and foreign exchange market stability policies.  相似文献

The toxic capsule crisis (TCC) shocked China in 2012, and seriously harmed consumer confidence. Based on a firsthand survey in 12 provinces with 850 observations, this paper examines Chinese consumers’ risk perceptions and risk attitudes about drugs after the TCC. The empirical results suggest that Chinese consumers’ risk perceptions (attributed likelihood of a drug safety accident occurrence) and risk attitudes (measured as level of concern about drug labeling) are weakly negatively correlated, but that risk perceptions are positively correlated with consumer concern about drug safety problems in general. Risk perception was higher among male consumers and those from rural areas, reporting a religious faith, of higher education, and with a family member who has experienced problems caused by drug safety problems. Those reporting a higher level of concern about drug safety issues, with a higher level of understanding of TCC, who reported less frequent physical examinations, and who searched for information after the TCC also had a higher level of risk perception. Being or having a family member who engaged in the health industry and being more satisfied with the government response to the TCC decreased risk perception. Regarding risk attitude, older consumers, those with a higher level of education and with a self-reported religious faith, and those less prepared including those who did not purchase health insurance, do not have health exams as frequently, and who do not take measures of protection and isolation when ill are more concerned about drug labeling information.  相似文献

We undertake a decomposition of the risk factor loadings of 15 national stock market returns from 1972 to 1990, using a variant of the Campbell-Shiller (1988) linearisation. (Campbell, John Y. and Shiller, Robert J., ‘The dividend-price ratio and expectations of future dividends and discount factors’, Review of Financial Studies, Vol. 1, 1988, pp. 195–228.) We find considerable variation among countries in the relative importance of a cash flow component and a discount rate component in determining the beta with the world equity index return and with other risk factors. Also, the substantial international heterogeneity in factor loadings suggests that a global portfolio allows ample hedging opportunities, presumably deriving from differences in underlying economic structure.  相似文献

We propose a novel class of convex risk measures, based on the concept of the Fréchet mean, designed in order to handle uncertainty which arises from multiple information sources regarding the risk factors of interest. The proposed risk measures robustly characterize the exposure of the firm, by filtering out appropriately the partial information available in individual sources into an aggregate model for the risk factors of interest. Importantly, the proposed risks can be expressed in closed analytic forms allowing for interesting qualitative interpretations as well as comparative statics and thus facilitate their use in the everyday risk management process of the insurance firms. The potential use of the proposed risk measures in insurance is illustrated by two concrete applications, capital risk allocation and premia calculation under uncertainty.  相似文献

The aim of this paper is to contribute to the debate on systemic risk by assessing the extent to which distress within the main different financial sectors, namely, the banking, insurance and other financial services industries contribute to systemic risk. To this end, we rely on the ΔCoVaR systemic risk measure introduced by Adrian and Brunnermeier (2011). In order to provide a formal ranking of the financial sectors with respect to their contribution to systemic risk, the original ΔCoVaR approach is extended here to include the Kolmogorov–Smirnov test developed by Abadie (2002), based on bootstrapping. Our empirical results reveal that in the Eurozone, for the period ranging from 2004 to 2012, the other financial services sector contributes relatively the most to systemic risk at times of distress affecting this sector. In turn, the banking sector appears to contribute more to systemic risk than the insurance sector. By contrast, the insurance industry is the systemically riskiest financial sector in the United States for the same period, while the banking sector contributes the least to systemic risk in this area. Beyond this ranking, the three financial sectors of interest are found to contribute significantly to systemic risk, both in the Eurozone and in the United States.  相似文献

This paper, which reinterprets previous work by Bradbury and Rouse (2002 ), addresses the risk quantification issue at an intuitive level. The insights provided by such quantification are discussed. Risk factors are associated with the risk-return concept. This allows measuring whether risks taken on are appropriately rewarded. The paper gives a non-technical exposition of DEA and outlines possible applications to accounting and finance. Using data for a large multinational, it shows how DEA analysis can be combined with internal audit procedures. It explains how the results obtained can be used to improve risk management.  相似文献

In the most recent stage of development of modern society, the growing complexity and dynamism of the contexts firms operate in has led to a relentless increase in the level of risk in all areas of firms’ management and activities. For this reason, the discipline and practice of risk management (RM) has taken hold more and more in very different sectors and contexts: from nuclear to supply chain to healthcare. The evolutionary path of RM has followed distinct paths of development that have adopted specific perspectives and, backed by different cultural matrices, led to unique approaches and methods. The aim of this paper is to provide a contribution to the identification and characterization of new paths of development based on a thorough analysis of the academic and managerial literature. This taxonomy can serve as an integrated reference to the RM discipline allowing those who deal with RM to identify and characterize the most suitable paths of development for a given context, within a comprehensive framework. This study can also promote a sort of ‘cross fertilization’ between experts in specific areas of RM as has been the case of clinical RM which draws from the experience gained in the field of complex engineering systems.  相似文献

The Scottish Government’s social care regulator, the Care Commission, seeks continual improvement in the quality of social care services. Its approach has been to establish a modern risk-based regulatory regime using separate measures of risk and quality. We evaluate this twin approach, firstly, in relation to the literature on predictors of poor service quality in care delivery; and, secondly, by interviewing a sample of Care Commission inspectors. We conclude that this system has important advantages, both in terms of regulatory transparency and the need for inspectors to remain sensitive to the separateness of risk and quality issues. Future revisions of risk and quality assessment within social care services, both in Scotland and further afield, should seek to minimise misunderstanding and conflict between regulators and regulatees on closely interrelated matters of risk, quality and efficiency.  相似文献

Basel II defines operational risk as the risk of direct or indirect loss resulting from inadequate or failed internal processes, people or systems or from external events. In the past decade, there have appeared a number of quantitative approaches to measuring this risk, approaches that abstract from market risk and reputational risk. The challenge is to develop operational risk measures in an asset management context where there is only limited information available about the incidence and severity of operational loss events. We survey different approaches to this problem and argue that managing this risk through operational due diligence is a source of alpha in this funds management context.  相似文献

The influence of incidental emotion on responsiveness to risk feedback was investigated. One hundred and eighty‐seven male and female undergraduate students experienced a film emotion induction procedure to elicit happiness, sadness, or neutral affect. They then received false feedback indicating that their risk of getting a fictional type of influenza was high or low, and were given the chance to obtain more information about this type of flu and how to prevent it. Among low‐risk participants, experiencing any emotion (happy or sad) resulted in obtaining more information than those in the neutral condition. Conversely, high‐risk participants who experienced any emotion took less information than those in the neutral group. High‐risk feedback produced less positive affect, more negative affect and worry, and higher risk perceptions than low‐risk feedback. The findings have implications for how threatening risk feedback will affect information seeking behavior in the context of an emotional state.  相似文献

This paper examines two arguments presented in Gray and Hall (2006). First, that the generally used estimate of 0.06 for the market risk premium within the Officer version of the capital asset pricing model (CAPM) and the generally used estimate of 0.50 for the parameter ‘gamma’ within the Officer framework are jointly inconsistent with evidence concerning the market risk premium in the standard version of the CAPM. Second, that the first two of these parameter estimates are also jointly inconsistent with the observed cash dividend yield on the Australian market. To resolve these problems, Gray and Hall recommend setting gamma to zero. The present paper shows that the first argument does not account for the fact that imputation induces a reduction in the market risk premium as defined in the standard version of the CAPM. The present paper also shows that both arguments identify a problem that characterizes only parts of the Officer framework, and these parts are not generally used in Australia. Therefore, rather than suggesting that gamma should be zero, Gray and Hall's analysis identifies parts of the Officer framework that should be avoided.  相似文献

In this paper, we identify initial macroeconomic and financial market conditions that help explain the distinct response of the real economy of a particular country to the recent global financial crisis. Using four measures of crisis severity, we examine a data set with over 90 potential explanatory factors employing techniques that are robust to model uncertainty. Four findings are of particular note. First, we find empirical evidence for the pivotal role of pre-crisis credit growth in shaping the real economy's response to the crisis. Specifically, a 1% increase in pre-crisis lending translates into a 0.2% increase in the cumulative loss in real output. Moreover, the combination of pronounced growth in lending ahead of the crisis and the country's exposure to external funding from advanced economies is shown to intensify the real downturn. Economies with booming real activity before the crisis are found to be less resilient to the global shock. Buoyant growth in real GDP in parallel with strong growth of credit particularly exacerbated the effects of the recent crisis on the real economy. Finally, we provide empirical evidence on the importance of holding international reserves in explaining the response of the real economy to the crisis. The accumulation of international reserves mitigated the harmful effects of financial stress on the real economy, in particular when domestic funding via credit is abundant. The results are shown to be robust to several estimation techniques, including those allowing for cross-country spillovers.  相似文献

The objective of this paper is to test whether the effect of variables such as knowledge, attitudes, trust, risk perception, and psychometric risk characteristics changes in the different stages of risk-related information processing. To address this question, a distinction is made between two information-processing steps, reception (measured as a person’s ability to retain the information communicated) and acceptance (measured as a person’s level of agreement with the communicated information). An empirical study was conducted, using a radiological accident (2008) in Belgium as a communication case study. Face-to-face interviews were conducted on a large sample of Belgian population representative with respect to province, region, level of urbanization, gender, age, and professionally active status (N?=?1031) and among the population living in vicinity of the accident (N?=?104). All factors were measured on reliable scales (Cronbach’s α?>?.75). The reception–acceptance model was used to produce new insights into risk communication. The results demonstrate that knowledge was the driving factor only for the reception of risk messages, while heuristic predictors such as psychometric risk characteristics, attitudes, and trust were most influential for the acceptance of risk messages. It is discussed how the results will facilitate a more thorough understanding of information processing and how they could be used to design more focused risk communication strategies.  相似文献

This paper addresses the expansion of risk practices through a case study of a government led project in Sweden purposed to develop a method to include social events in mandatory risk practices. Social heterogeneity was to be transformed into straightforward causality in order to turn the social into a manageable object. In this regard, the project was quite successful. By inviting social scientists into the process, otherwise often marginalized within risk practice, causality and quantifiable risk factors could be established and the model became a rigorous and legitimate scientific model. Although experts were granted significant autonomy and became experts far beyond their own area of expertise, the success of the model lies rather in allowing experts authority within confined boundaries. Grand narratives and critical perspectives are disregarded as too abstract and if social scientists are to infuse aspects of social critique they must adapt to these circumstances: they must become instrumentalists.  相似文献

Over the past ten years or so, there have been multiple attempts to site and build carbon capture and storage (CCS) facilities in Europe, North America and elsewhere. To date, most of those attempts have not been successful. In Europe, for example, there are currently no commercial CCS facilities in operation. There are a number of reasons for this, ranging from lack of political will, the collapsing price of CO2, lack of commercial drivers to capture and store CO2, and public opposition to the proposed facilities. There have been several case studies examining the communication challenges associated with the siting of CCS facilities. Up till now, most of this research has been carried out by climate change or carbon policy experts as well as social researchers rather than scientists representing the wider risk communication community, aside from some notable exceptions. This study does the opposite by examining CCS from a broader risk communication perspective. It provides a brief overview of risk communication theory in order to situate some of the findings of the CCS communication research, and then, it makes some recommendations on how the siting of CCS facilities could be improved including the importance of trust, proactive communication and early stakeholder involvement. In conclusion, this study notes that if the science associated with the technology is communicated in the correct manner and if the key risk communication recommendations are adhered to, then the siting of future CCS facilities should be successful.  相似文献

Research on risks has mainly been devoted to detailed analyses of such risks that are subject to public debate and policy decision making. However, many if not most of the risks that are now the subject of regulation were once neglected. Experts in conjunction with regulators have a crucial role in putting risks on the policy agenda. But what views do experts have on the matter of attention to risks? In order to answer this question risk assessment experts were asked to list the risks they considered to be over‐emphasized, respectively neglected. Radiation risks constituted the largest category of risks reported to be over‐emphasized. Other risks often reported to be over‐emphasized included BSE, GMOs, amalgam, and air traffic. Lifestyle risks were the largest category of risks reported to be neglected. Other risks often listed as neglected included radon (as an exception within the radiation category), road traffic, socio‐economic risks, energy production excluding nuclear power, and local accidents (including fires and workplace accidents). Risks mentioned about equally often as neglected and over‐emphasized included chemicals and crime. There was a correlation between perceived risk and neglect: risks considered to be neglected were also judged as larger. For a comparison, the topics of articles in the journal Risk Analysis from 1991–2000 were categorized into the same risk categories that were used for the questionnaire. The risks most commonly treated in the journal (chemicals and cancer) coincided with the risks which experts in our survey considered to be overemphasized rather than neglected.  相似文献
