This article deals with demand for insurance with a background risk in a nonprobabilized uncertainty framework, where preferences are represented by a nonadditive model of decision making. The Choquet expected utility model that we use generalizes expected utility and allows for a separation of the attitude towards uncertainty and the attitude towards wealth. When the insurable and the background risk are comonotone, the impact of the background risk on the demand for insurance is related to the attitude towards wealth. In contrast, when the two risks are anticomonotone, the attitude towards uncertainty is determinant. In this case, some of the resulting behaviors cannot be explained by the standard expected utility model.  相似文献

Recent work suggests that sentiment traders shift from safer to more speculative stocks when sentiment increases. Exploiting these cross‐sectional patterns and changes in share ownership, we find that sentiment metrics capture institutional rather than individual investors’ demand shocks. We investigate the underlying economic mechanisms and find that common institutional investment styles (e.g., risk management, momentum trading) explain a significant portion of the relation between institutions and sentiment.  相似文献

基于2005年1月至2019年6月间公开发售的2246支来自全球的基建基金数据,本文研究基建基金投资者偏好和委托代理问题。研究结果表明:投资者偏好客户忠诚度较高、投资于国际市场、团队管理型的基建基金;在基建基金公司层面,投资者存在跟风投资行为,且随着信息不透明度和收益不确定性加剧;投资者与基金管理人存在委托代理问题,体现为基金费率与预期业绩不匹配。该现象源于基金管理人利用投资者较高的预期收益设置费率,可以由基金特征因素和年份效应解释,尤其是投资于国际市场、收益分配或非团队管理等特征。本文结论对创新基础设施融资模式、稳定资金来源和微观审慎监管具有重要借鉴意义。  相似文献

Previous work finds a negative and significant relation between the maximum daily return over the past one month and expected future stock returns. We determine that this effect is more pronounced for stocks that achieve their maximum daily returns toward the end of the month and stocks that are associated with capital losses show greater reversals. These results suggest the effect is related to investor attention and risk preferences.  相似文献

We use various stochastic dominance criteria that account for(local) risk seeking to analyze market portfolio efficiencyrelative to benchmark portfolios formed on market capitalization,book-to-market equity ratio and price momentum. Our resultssuggest that reverse S-shaped utility functions with risk aversionfor losses and risk seeking for gains can explain stock returns.The results are also consistent with a reverse S-shaped patternof subjective probability transformation. The low average yieldon big caps, growth stocks, and past losers may reflect investors’twin desire for downside protection in bear markets and upsidepotential in bull markets.  相似文献

By focusing on the decisions of investors to invest in cross‐listed stocks, this paper presents new evidence on why we observe striking differences in the percentage of trade in foreign markets for cross‐listed stocks. With a large sample of Toronto Stock Exchange (TSX) stocks cross‐listed in the U.S. and Canada, we document the effect of investor recognition and risk characteristics on the distribution of trading volume. Firms that are more visible to American investors are traded more heavily in the U.S. At the same time, firms that offer diverse risk characteristics are attractive to Americans. While investors understand the benefits of international diversification, as they are attracted to stocks that are different (e.g., the stock of small firms with few assets in the U.S.), they also seek stocks that provide them with high returns.  相似文献

The objective of this study is to investigate factors that influence investor information demand around earnings announcements and to provide insights into how variation in information demand impacts the capital market response to earnings. The Internet is one channel through which public information is disseminated to investors and we propose that one way that investors express their demand for public information is via Google searches. We find that abnormal Google search increases about two weeks prior to the earnings announcement, spikes markedly at the announcement, and continues at high levels for a period after the announcement. This finding suggests that information diffusion is not instantaneous with the release of the earnings information, but rather is spread over a period surrounding the announcement. We also find that information demand is positively associated with media attention and news, and is negatively associated with investor distraction. When investors search for more information in the days just prior to the announcement, preannouncement price and volume changes reflect more of the upcoming earnings news and there is less of a price and volume response when the news is announced. This result suggests that, when investors demand more information about a firm, the information content of the earnings announcement is partially preempted.  相似文献

The Role of Risk Management and Governance in Determining Audit Demand   总被引:1,自引:0,他引:1  
Abstract:  Most prior research into audit fees has been based on a theoretical model which treats audit fees as the by-product of a production function ignoring potential demand forces that may drive the level of the audit fee. Inspired by prior 'anomalous' results, we take a different perspective by focusing on demand factors that may affect the level of the audit fee. Using data collected from a sample of listed companies in Belgium, we consider both disclosures about risk and risk management and actual decisions about corporate governance to examine whether audit fees are higher when these demand forces exist. In general, we expect that external auditing will increase in situations where there are multiple stakeholders with individual risk profiles who can shift some of the cost of monitoring to other stakeholders. Consistent with our theory and expectations, our results indicate that audit fees are higher when a company has an audit committee, discloses a relatively high level of financial risk management, and has a larger proportion of independent Board Members. Audit fees are lower when a company discloses a relatively high level of compliance risk management. The latter result indicates that controls are only complementary as long as they are voluntary, as mandated controls act as substitutes for non-mandated controls.  相似文献

Using asset market data, as well as theoretical relations between investors' preferences,option-implied, risk-neutral, probability distribution functions (PDFs,) and index-implied,actual, PDFs, this paper extracts a time-series of investors' relative risk aversion (RRA)functions. Based on results recently derived by Benninga and Mayshar (2000), thesefunctions are used to recover the evolution of risk preferences heterogeneity. Applyingnon-parametric estimation on European call options written on the S & P500 index, wefind that: (i) the RRA functions are decreasing; and (ii) the constructed risk preferencesheterogeneity series is positively correlated in a static, as well as a dynamic, setup witha prevalent proxy for investors heterogeneity, namely, the spread between auction- andmarket-yields of Treasury bills.  相似文献

Using four different proxies for a firm's investor base we demonstrate that idiosyncratic risk premiums are larger for neglected stocks and smaller or economically insignificant for visible stocks. Since neglected stocks have greater idiosyncratic volatility (IV), the total IV risk premium (price × quantity) for neglected stocks will be greater than that of visible stocks. Additionally, we find a positive size effect and negative beta effect after controlling for IV. Overall, our results provide strong support for Merton's theory that market segmentation induced by incomplete information is an important component of the influence of IV in the cross‐section of returns.  相似文献

Equity Risk, Conversion Risk, and the Demand for Insurance   总被引:1,自引:0,他引:1  
Existing insurance theory fails when applied to real property because it does not account for variations in the economic environment. The article studies optimal property insurance in the presence of two sources of variation: equity risk and conversion risk. Equity risk is randomness of the value of a property. It tends to raise demand for conventional insurance. In contrast, conversion risk is randomness in the value the property would have if, after severe damage, it were converted to the highest‐valued use. It is distinct from equity risk because the highest‐valued use is typically not the current one. Under independent conversion risk, the optimum upper limit is a compromise among underlying conversion thresholds. Absent independence, the optimum can be quite different. Conversion risk can raise or lower the demand for property insurance. Insurance contracts that fail to address conversion tend to undermine the orderly disposition of obligations and reduce the gains from reallocation of risks through insurance.  相似文献

This study examines the determinants of earnings management in an international setting using the limited investor attention model of Hirshleifer and Teoh ( 2003 ). The model predicts that investor attention reduces earnings management. I use analyst following, institutional ownership, and Big N auditor choice to proxy for investor attention. I have four key findings. First, I document that financial analysts curb earnings management in U.S. firms but not in non‐U.S. firms. Second, I document that institutional block‐holdings curb earnings management across the world. Third, Big N auditors reduce earnings management in U.S. firms but not in non‐U.S. firms. Fourth, I document that corporate governance mechanisms reduce earnings management in U.S. firms but not in non‐U.S. firms.  相似文献

本文以2003—2019年间开放式主动管理型的股票型和偏股型基金为样本,以持仓占比为权重估算基金投组中A股的总市场风险暴露,检验结果表明,该序列上升反映了基金面临的隐性杠杆约束收紧,刻画了市场的弱流动性。内在逻辑在于,流动性收紧时,投资者难以通过融资直接增加杠杆,更倾向于重仓持有高市场风险头寸的股票而间接实现杠杆。本文发现隐性杠杆约束所刻画的风险在股票或基金收益截面上的无条件定价基本失效,而条件定价则依赖于低市场情绪与弱流动性。分解基金持股的敞口,进一步发现,因中小盘基金在流动性收紧时具有更强的流动性偏好,其持股的市场风险头寸能够更敏锐地捕捉到弱流动性风险。  相似文献

Charges that geographical redlining is widely practiced by mortgage lenders and is associated with racial discrimination have received much attention. However, empirical research in this area has yet to document a convincing answer to the question of whether redlining even exists. Much of the previous research in this area has suffered from failure to account for variations in risk, and/or failure to adequately control for geographical differences in demand. This study addresses these problems in an effort to determine whether the disparity in the flow of mortgage credit can be explained by differences in risk and demand.  相似文献

The demand for insurance against loss from a particular risky asset is likely to depend on other risks the decision-maker faces. For independently distributed other risks, referred to as background risk, Eeckhoudt and Kimball [1992] determine the effect on insurance demand of introducing background risk. Recently, Eeckhoudt, Gollier, and Schlesinger [1996] determine conditions on preferences such that first- and second-degree stochastic deteriorations in background risk lead to a decrease in the decision-maker's willingness to accept other risks. These results, although formulated in a general decision model, also apply to insurance demand. This article continues analysis of this question by determining the effect on insurance demand of several other general changes in background risk.  相似文献
