We examine risk attitudes under regret theory and derive analytical expressions for two components—the resolution and regret premiums—of the risk premium under regret theory. We posit that regret-averse decision makers are risk seeking (resp., risk averse) for low (resp., high) probabilities of gains and that feedback concerning the foregone option reinforces risk attitudes. We test these hypotheses experimentally and estimate empirically both the resolution premium and the regret premium. Our results confirm the predominance of regret aversion but not the risk attitudes predicted by regret theory; they also clarify how feedback affects attitudes toward both risk and regret.  相似文献

We study comparative statics of Nth-degree risk increases within a large class of problems that involve bidimensional payoffs and additive or multiplicative risks. We establish necessary and sufficient conditions for unambiguous impact of Nth-degree risk increases on optimal decision making. We develop a simple and intuitive approach to interpret these conditions : novel notions of directional Nth-degree risk aversion that are characterized via preferences over lotteries.  相似文献

This paper complements evidence on the Allais paradox from advanced countries and educated people by a novel investigation in a poor rural area. The share of Allais-type behavior is indeed high and related to indicators of “lacking ability,” such as poor education, unemployment, and little financial sophistication. Based on prospective reference theory, we extend these characteristics by biased processing of probabilistic information. Finally, we reveal that Allais-type behavior is linked to risk-related characteristics, such as risk tolerance and optimism. This indicates a potential problem as exactly the more dynamic among the poor tend to make inconsistent decisions under uncertainty.  相似文献

We use the multiple price list method and a recursive expected utility theory of smooth ambiguity to separate out attitude towards risk from that towards ambiguity. Based on this separation, we investigate if there are differences in agent behaviour under uncertainty over gain amounts vis-a-vis uncertainty over loss amounts. On an aggregate level, we find that (i) subjects are risk averse over gains and risk seeking over losses, displaying a “reflection effect” and (ii) they are ambiguity neutral over gains and are mildly ambiguity seeking over losses. Further analysis shows that on an individual level, and with respect to both risky and ambiguous prospects, there is limited incidence of a reflection effect where subjects are risk/ambiguity averse (seeking) in gains and seeking (averse) in losses, though this incidence is higher for ambiguous prospects. A very high proportion of such cases of reflection exhibit risk (ambiguity) aversion in gains and risk (ambiguity) seeking in losses, with the reverse effect being significantly present in the case of risk but almost absent in case of ambiguity. Our results suggest that reflection across gains and losses is not a stable individual characteristic, but depends upon whether the form of uncertainty is precise or ambiguous, since we rarely find an individual who exhibits reflection in both risky and ambiguous prospects. We also find that correlations between attitudes towards risk and ambiguity were domain dependent.   相似文献

Existing research demonstrates that parent and child gender may influence important aspects of family relationships; however, most research in this area has been conducted with non‐clinical samples. As clinicians, it is important to consider how gender impacts family relationships, particularly among vulnerable families. This study examined the intersections of gender role attitudes and parenting practices among 34 parents involved with the child welfare system and referred for clinical intervention. Using a mixed methods design, themes regarding gender role beliefs and parenting practices were found through qualitative interviews with parents. Findings suggested that fathers felt responsible for financially providing for their families and expressed challenges in communicating with mothers, and mothers described challenges they face because of a lack of father involvement. Parents also discussed a perceived need to monitor daughters closely while fostering the independence of their sons. Results of the qualitative analyses were supported by quantitative findings indicating significant differences in harsh and inconsistent discipline practices and clear expectations for girls compared to boys. The discussion addresses implications for clinicians, including how a feminist family therapy perspective may help promote client influence over traditional gender norms by questioning gender role attitudes and exploring alternate narratives that may impact family dynamics.  相似文献

Contemporary society is beset with subtle racial tensions. Modern racism is a form of racism often found in modern, politically correct America. In this form of racism, racist beliefs are often expressed only indirectly. In the present paper, race differences in attitudes about and perceptions of racism were examined through the use of a survey. Results showed several differences in the way Blacks and Whites perceive race relations on a university campus. This information helps to gain insight into the causes of modern racial tensions. The results also suggest strategies to reduce racism on college campuses.  相似文献

In a recent article entitled “Putting Risk in its Proper Place,” Eeckhoudt and Schlesinger (2006) established a theorem linking the sign of the n-th derivative of an agent’s utility function to her preferences among pairs of simple lotteries. We characterize these lotteries and show that, in a given pair, they only differ by their moments of order greater than or equal to n. When the n-th derivative of the utility function is positive (negative) and n is odd (even), the agent prefers a lottery with higher (lower) n + 2p-th moments for p belonging to the set of positive integers. This result links the preference for disaggregation of risks across states of nature to the complete structure of moments preferred by mixed risk averse agents. It can be viewed as a generalization of a proposition appearing in Ekern (1980) which focused only on the differences in the n-th moments.  相似文献

This paper investigates similarities and differences between Arab and Jewish professionals living in Israel regarding their knowledge and attitudes about AIDS. Although AIDS in Israel is not considered to be a pressing crisis, the aim of the research is to document and analyse what professionals in the helping professions – Arabs and Jews alike – know and how they feel about AIDS. The study also explores thoughts and feelings concerning AIDS–related education and training. This is the first scholarly attempt to compare Israeli and Arab professionals' attitudes and knowledge about such a stigmatised topic as the AIDS epidemic. The study sample consists of 350 professionals, including 218 Jews and 132 Arabs, working in various social and health–care agencies providing services to the Arab population. Professionals include social workers, nurses, occupational therapists, psychologists, and special education teachers and counsellors. Results indicate that Jewish professionals scored significantly higher on both knowledge and attitude scales than did their Arab counterparts. Two regression models predicting both knowledge and attitudes are presented, and their implications are discussed using several frameworks: the status of the disease, including perception of the threat; perception of adequacy of training; educational environment; and the socialisation process of Arab professionals in Israel  相似文献

The construction of parents' cannabis use in the context of child protection has far-reaching implications for how their parenting is perceived and assessed and for the decisions made regarding their children's lives. Yet little is known about the meanings various stakeholders in child protection processes attribute to parents' cannabis use. This paper aims to explore constructions of parents' cannabis use in child protection court proceedings and position them within a political and social context. A qualitative data mining method was used to examine 32 Family Court judgements in care proceedings that involved parents using cannabis in England and Wales. The analysis of the judgements revealed that most portrayed parents' cannabis use as a negative, deviant and harmful activity. Three constructions of cannabis use were identified: cannabis use as a risk to children, cannabis use as proof of parents' deficits, and cannabis use as (responsible) self-medication. The discussion considers the findings in light of two social and political processes that underpin child protection policy and practice: the adoption of a risk perspective and the manifestation of othering processes. Implications for policy and practice highlight the importance of developing a critical framework for responding to parental cannabis use.  相似文献

It is commonly assumed that popular support for national pension systems depends on widespread satisfaction with projected benefit levels among the working age population, and in particular that public support for the system will be jeopardised if the taxpayers do not feel confident about eventually receiving the promised benefits. On the basis of Norwegian survey data, two sets of questions are addressed in the article: (1) Is there a widespread lack of confidence in and satisfaction with the Norwegian National Insurance pension scheme? and (2) Is there an association between confidence and satisfaction and people's political attitudes towards the National Insurance pension scheme? Although we do not find any signs of a dramatic erosion of confidence towards the system, we do find that overall satisfaction with projected benefits is low among the working age population. Contrary to what one might expect, however, confidence and satisfaction from the point of view of individual interests appear not to be associated with a political preference for privatisation.  相似文献

Experiments on intertemporal consumption typically show that people have difficulties in optimally solving such problems. Previous studies have focused on contexts in which agents are faced with risky future incomes and have to plan over long horizons. We present an experiment comparing decision making under certainty, risk, and ambiguity, over a shorter lifecycle. Results show that behavior in the ambiguity treatment is markedly different than in the risk condition and it is characterized by a significant pattern of under-consumption.  相似文献

The paper explored how to promote constructive intergroup relations among children and young people in a context of protracted conflict. Across two studies, the Empathy–Attitudes–Action model was examined in middle childhood and adolescence. More specifically, we tested the relations among dispositional empathy, out‐group attitudes, and prosocial behaviors for youth born after the peace agreement in Northern Ireland. In one correlational (Study 1: N = 132; 6–11 years old: M = 8.42 years, SD = 1.23) and one longitudinal design (Study 2: N = 466; 14–15 years old), bootstrapped mediation analyses revealed that empathy was associated with more positive attitudes toward the conflict‐related out‐group, which in turn, was related to higher out‐group prosocial behaviors, both self‐report and concrete actions. Given that out‐group prosocial acts in a setting of intergroup conflict may serve as the antecedents for peacebuilding among children and adolescents, this study has intervention implications.  相似文献

The study describes collaborative involvement of child welfare agencies in Sweden with mandated reporters and analyses the association between socioeconomic and demographic factors as well as collaborative involvement on referral rates. The empirical material consists of data collected on location in 100 Swedish child welfare agencies, augmented with register data. The study shows that: (i) collaboration is common in the child welfare field, (ii) structural factors moderately predict municipal variations in child welfare referrals and (iii) most importantly, that collaboration on the aggregate level seems to serve as a marginal, or even counter-productive, measure in identifying children and adolescents at risk. The results are particularly discussed in the context of policy principles in Swedish child welfare, i.e. collaboration as a statutory requirement for child welfare agencies and the official notion of collaboration as an important means to facilitate early interventions.  相似文献

This study investigates staff and family attitudes towards the use of the fences that surround many aged care facilities in Australia, in the context of indefinite detention of people with dementia. This indefinite detention has been described in a report from an Australian Senate Inquiry as “a significant problem within the aged care context”, which “is often informal, unregulated and unlawful”. Five focus groups comprising direct care workers, family members, nurse unit managers and facility managers discussed the reasons for and their attitudes towards fences. The results show a tension between the provision of physical and emotional safety. This is to say that even while it is illegal to detain people with dementia against their will, and even while participants understood the negative impact of fences on the well‐being and emotional safety of people with dementia, they accepted and supported the presence of perimeter fences because they provided the perception that fences kept people with dementia physically safe. This has implications for redressing the balance between physical and emotional safety in policy and practice.  相似文献
