近年来分红保险已成为我国保险市场的热销产品,它几乎占据了寿险市场的半壁江山,但分红保险负债的确认与计量问题,特别是分红保险红利负债的确认与计量问题在我国并未形成统一的规范,本文根据分红保险的不同红利分配方式对分红保险合同红利负债的确认与计量问题进行研究。 相似文献

我国证券市场风险收益特征的行为基础 总被引:2,自引:0,他引:2
海通证券公司研究所联合课题组 《经济理论与经济管理》2003,(7):27-32
我国证券市场的风险收益具有以下特征:(1)资本资产定价模型所揭示的风险收益关系在我国股市并不显著。(2)我国证券市场系统性风险占整体风险的比例较高。(3)从趋势上看,无论个股还是行业系统性风险占整体风险的指标没有明显的下降趋势。这些特征根源于我国特定的投资者结构以及不同投资者的风险厌恶特性和对私人信息的偏好特性。因此,投资者应针对上述特征,在集中投资、反向交易和降低交易频率等方面调整交易策略,提高投资收益率。 相似文献

The objective of this study is to estimate willingness to pay (WTP) for the reduction of mortality risks caused by fossil
fuel (natural gas, coal and oil) versus nuclear electric power generation systems and to examine the influence of risk characteristics
involved with electric power generation on WTP. A choice experiment was conducted to achieve these objectives. The attributes
for nuclear risks in the experiment included the probability of disasters and the expected losses if a disaster occurs. We
find evidence of (i) a baseline effect (where WTP is sensitive to hypothetical versus actual baseline expected mortality);
(ii) a ‘labeling effect,’ where, surprisingly, the term ‘nuclear’ has no effect on WTP, but the term ‘fossil-fueled power
generation’ results in lower WTP; and (iii) disaster aversion, meaning that people focus on the conditional loss from a nuclear
disaster, not the probability. We also find that the WTP for reducing deaths from a nuclear disaster is about 60 times the
WTP for routine reducing fossil-fuel generation-related deaths. 相似文献

Summary. Starr (1973) showed that, if people have different subjective probabilities, ex ante and ex post efficiency conflict. Conversely, under the simple preferences that he considered, the discrepancy between ex ante and ex post efficiency disappears when subjective probabilities are identical. Here I consider identical subjective probabilities, but
more general preferences. First, risk attraction is admitted. Second, I dispense with the double requirement (dubbed IZU)
of additive separability and state-independence of the utility of zero-date consumption, an unrealistic requirement when modeling
the investment in durable goods. I find that, under IZU, and as long as ex post preferences satisfy the natural assumption of quasiconcavity (and satisfy some technical qualifications), an ex ante efficient allocation is indeed ex post efficient, but the converse is not necessarily true under risk attraction. If, on the other hand, IZU is violated, then one
can have ex ante efficient allocations that are not ex post efficient, and vice-versa, even under risk aversion.

Evaluating flood risk management options in Scotland: A participant-led multi-criteria approach 总被引:1,自引:0,他引:1
Wendy Kenyon 《Ecological Economics》2007,64(1):70-81
The characteristics of flood risk management include complexity, large spatial scales, inter-temporal issues, plural values and conflicts of interests. It is argued that issues with such characteristics require public participation in the decision making process. This study builds on existing deliberative processes to develop a new participant-led multi-criteria method to evaluate flood risk management options in Scotland. The results show that participants preferred regeneration or planting of native woodland to other flood management options, and least preferred building flood walls and embankments. The design of the workshops allowed a rich dataset to reveal the thinking behind such results and provided a deeper understanding of why participants came to these conclusions. 相似文献

This paper examines the short and long-term price linkages among major art and equity markets over the period 1976–2001. The art markets examined are Contemporary Masters, French Impressionists, Modern European, 19th Century European, Old Masters, Surrealists, 20th Century English and Modern US paintings. A global equity index (with dividends and capitalisation changes) is also included. Multivariate cointegration procedures, Granger non-causality tests, level VAR and generalised variance decomposition analyses based on error-correction and vector autoregressive models are conducted to analyse short and long-run relationships among these markets. The results indicate that there is a stationary long-run relationship and significant short and long run causal linkages between the various painting markets and between the equity market and painting markets. However, in terms of the percentage of variance explained most painting markets are relatively isolated, and other painting markets are generally more important than the equity market in explaining the variance that is not caused by innovations in the market itself. This suggests that opportunities for portfolio diversification in art works alone and in conjunction with equity markets exist, though in common with the literature in this area the study finds that the returns on paintings are much lower and the risks much higher than in conventional financial markets.The authors would like to thank delegates to the 14th Australasian Finance and Banking Conference, University of New South Wales, seminar participants at the Queensland University of Technology and Massey University, Masaki Katsuura, and two anonymous referees for helpful comments on earlier versions of this paper.
