This paper uses empirical evidence to examine the operational dynamics and paradoxical nature of risk management systems in the banking sector. It demonstrates how a core paradox of market versus regulatory demands and an accompanying variety of performance, learning and belonging paradoxes underlie evident tensions in the interaction between front and back office staff in banks. Organisational responses to such paradoxes are found to range from passive to proactive, reflecting differing organisational, departmental and individual risk culture(s), and performance management systems. Nonetheless, a common feature of regulatory initiatives designed to secure a more structurally independent risk management function is that they have failed to rectify a critical imbalance of power - with the back office control functions continuing to be dominated by front office trading and investment functions. Ultimately, viewing the 'core' of risk management systems as a series of connected paradoxes rather than a set of assured, robust practices, requires a fundamental switch in emphasis away from a normative, standards-based approach to risk management to one which gives greater recognition to its behavioural dimensions. 相似文献

The paper investigates the extent of the impact from changes in asset price and risk on corporate investment behaviors as well as the real economy. The results support the unidirectional causality effects from asset price fluctuations on the macro-level. By applying quarterly data of Chinese listed companies, we further find the existence of balance sheet effect on the firm-level, which suggests that the changes in asset prices and risk affect the net asset value, and consequently influence corporate investment decisions. More importantly, the balance sheet effect appears to be much more significant after the implementation of new fair value accounting standards in 2007. The impact on the real economy from asset price risk is found to be more prominent as well. 相似文献

In premium auctions, the highest losing bidder receives a reward from the seller. This paper studies the private value English premium auction (EPA) for different risk attitudes of bidders. We explicitly derive the symmetric equilibrium for bidders with CARA utilities and conduct an experimental study to test the theoretical predictions. In our experiment, subjects are sorted into risk-averse and risk-loving groups. We find that revenues in the EPA are significantly higher when bidders are risk loving rather than risk averse. These results are partly consistent with theory and confirm the general view that bidders' risk preferences constitute an important factor that affects bidding behavior and consequently also the seller's expected revenue. However, individual subjects rarely follow the equilibrium strategy and revenue in our experiment is lower than in the symmetric equilibrium. 相似文献

We investigate how investors should optimally choose to invest in a dynamically complete international market. We find closed-form solutions for the optimal investment strategy and for the wealth loss an investor suffers from not investing internationally. Theoretically, we show that the gain from international investment is due to the speculative investment only, and why it is important for an investor from a large economy to invest in a small economy. In a numerical example we compare the wealth losses investors from Denmark and the U.S. suffer due to home bias. 相似文献

A decision-analytic model for avoiding a risky activity is presented. The model considers the benefit and cost of avoiding the activity, the probability that the activity is unsafe, and scientific tests or studies that could be conducted to revise the probability that the activity is unsafe. For a single decision maker, thresholds are identified for his or her current subjective probability that the activity is unsafe. These thresholds indicate whether the preferred course of action is avoiding the activity without further study, engaging in the activity without further study, or conducting a test or research programme to obtain additional information and following the result. When these thresholds are low, precautionary action is more likely to be warranted. When there are multiple stakeholders, differences in their perceptions of the benefit and cost of avoidance and differences in their perceptions of the accuracy of the additional information provided by the test or research programme combine to create differences in their decision thresholds. Thus, the model allows for the rational expression of differences among parties in a way that highlights disagreements and possible paths to conflict resolution. The model is illustrated with an application to phytosanitary standards in international trade and examined in terms of recent empirical research on lay perceptions of risks, benefits, and trust. Further research is suggested to improve the elicitation of model components, as a way of fostering the legitimate application of risk-based decision analysis in precautionary policy making. 相似文献

随着金融市场理论研究和实践检验的不断发展,资本市场的许多基础理论受到了极大的挑战,与现有理论相悖的异象不断涌现。新近兴起的实验经济学为人们研究资本市场提供了一条更为有效的途径。本文分析了实验方法在资本市场研究中的利与弊,介绍了部分资本市场实验的设计过程,并应用该方法分析了风险与收益、资本市场的效率、市场泡沫的产生和破灭、CAPM理论,以及交易制度等。文章指出,在资本市场中运用实验方法进行研究,具有可控性、可比性以及可重复性等优点,为我们对于资本市场诸多理论进行检验提供了可能。在资本市场实验的设计中,我们不但需要考虑实验的各种交易制度,还需要考虑到被试人员的选择、交易资产的确定以及市场信息的设计等很多问题,只有对这些问题进行全面地考虑,才能保证实验结果的可信度,进而为我们对于各种金融理论的检验提供可能。 相似文献

Good demand estimates are the key to effective pricing decision-making. However, they are subject to a high degree of uncertainty due to various factors that are unpredictable or difficult to model, thus making pricing decisions risky. This research provides a simple proposal for a robust optimization methodology that incorporates both demand uncertainty and the decision maker's degree of risk aversion. Uncertainty is explicitly considered for two coefficients of a linear demand function, price expressions are derived, and a criterion is proposed for defining the degree of risk aversion. The resulting model is also applied to an exponential demand case to better reflect a more realistic retail setting. 相似文献
