Through surveys of students and junior professionals and interviews with business and government executives, we studied Chinese choices and fairness perceptions in risky health and safety decisions. The survey responses were compared with American responses from an earlier study by Keller and Sarin.The survey results show that the American and Chinese respondents had similar fairness perceptions, but the Chinese did not make decisions that were consistent with their fairness perceptions, whereas the Americans did. We found that the middle-age Chinese professionals tended to make choices that were more different from the Americans than were the choices of the young Chinese management students. It is likely that these discrepancies were caused by cultural differences, with the younger Chinese tending to face a stronger Western influence.The insights from the survey results were enriched by interviews that revealed fairness perceptions of Chinese business and government executives. A framework to interpret cultural influences on decision making was also proposed.  相似文献

The relationship between spending on education and equal opportunity has been a subject of debate for several decades. This study aims to shed light on this debate by examining correlations between the distribution of Blue Ribbon awards to Indiana middle and high schools and per pupil expenditure. Based on criteria that include curricula, instruction, school climate, leadership, community support, goal setting and attainment, success with all students, skill development, and character education, Blue Ribbon School awards are a recognition of outstanding achievement given by the federal government. Using total federal, state, and local expenditures as the basis for comparison, we found that the federal government did not select more wealthy schools than poor schools for the Indiana Blue Ribbon School awards. However, there was a large difference in the expenditures per pupil in the Indiana districts with Blue Ribbon schools vs. the 30 randomly selected Indiana districts without Blue Ribbon schools. Total local sources were significantly greater in Blue Ribbon school districts than in non-Blue Ribbon school districts. A discussion of items related to the power, prestige, and wealth of the award-winning schools is included.  相似文献

This paper reports an empirical investigation of the effects of three pictorial forms of problem representation on conformance with the Reduction of Compound Alternatives Principle of expected utility theory. The most common form of representation, written problem statements, was compared with three pictorial representations: tubes containing one hundred labeled balls, decision matrices with each column proportional in size to the probability of the corresponding event, and bar graphs. The tubes representation led to fewer violations of the Principle. In addition, when subjects were trained to construct proportional matrices from written problem statements, they exhibited fewer violations than those who received the same problems already formatted in proportional matrices. The results reported here should contribute to the development of a theory of the way people frame decision problems.  相似文献

International research consistently shows that high-stakes exams are a significant source of stress and worry for students within secondary education. Existing research focuses on individual variation in exam-related stress levels among students with very little attention given to the influence of school context on student stress. Using data from the Irish Post-Primary Longitudinal Study, a mixed methods study of secondary students, this paper examines both individual and school level factors influencing the levels of stress among students preparing for the nationally standardised Leaving Certificate examination. The paper presents new findings which highlight the potential role of schools in ameliorating student stress. Findings show that student stress is not only influenced by individual-level factors but that certain aspects of the schooling process impact on stress levels. In particular, the quality of student–teacher interaction and peer relations within the school are found to have a significant impact on student stress levels. Students with more positive interactions with their teachers have lower stress levels with higher stress levels among those who have experienced bullying from peers. Stress is also influenced by programme choice at upper secondary level and the extent to which students are facilitated in their choice of subjects.  相似文献

Wealth aggregates implied by the Household Finance and Consumption Survey (HFCS) usually yield much lower amounts than macroeconomic statistics reported in the National Accounts. An important source of this gap may be the under-representation of the wealthiest households in the HFCS. This article therefore combines a semi-parametric Pareto model estimated from top survey data and observations from rich lists with a non-parametric stratification approach to quantify the impact of the missing wealthy households on component-specific micro-macro gaps. We find that unadjusted micro data substantially underestimates wealth inequality. The largest effects are documented for equity. For other components, the missing wealthy explain less than ten percentage points of the micro-macro gap. We find that differences in oversampling strategies limit the cross-country comparability of unadjusted survey-implied wealth distributions and that our top tail adjustment leads to measures that are internationally better comparable.

Effects of Outcome and Probabilistic Ambiguity on Managerial Choices   总被引:1,自引:0,他引:1  
Information ambiguity is prevalent in organizations and likely influences management decisions. This study examines, given imprecise probabilities and outcomes, how managers make choices when they are provided with single-figure benchmarks. Seventy-nine MBA students completed two experiments. We found that, in a decision framed as a decision under certainty involving an ambiguous outcome, the majority of the subjects were ambiguity prone in the loss condition and switched to ambiguity aversion in the gain condition. However, in the presence of probabilistic ambiguity in a decision under risk, this expected switching pattern was shown only when the difference in riskiness between the two choice options (in the loss condition) was perceived to be relatively small. In a companion study, we used a written protocol approach to identify factors that affect decision makers' investment choices when faced with ambiguous outcomes. Protocols frequently mentioned that the ambiguous outcome option was risky, even in the case which was framed as a decision under certainty in the problem statement. In a decision under risk with ambiguous outcomes, the combination of probabilistic risk and outcome ambiguity was seen as even more risky.  相似文献

Karni and Safra [8] prove that the Becker-DeGroot-Marschak mechanism reveals a decision maker's true certainty equivalent of a lottery if and only if he satisfies the independence axiom. Segal [17] claims that this mechanism may reveal a violation of the reduction of compound lotteries axiom. This paper empirically tests these two interpretations. Our results show that the second interpretation fits better with the collected data. Moreover, we show by means of some nonexpected utility examples that these results are consistent with a wide range of functionals.  相似文献

Insurer ambiguity and market failure   总被引:2,自引:2,他引:2  
A series of studies investigate the decision processes of actuaries, underwriters, and reinsurers in setting premiums for ambiguous and uncertain risks. Survey data on prices reveal that all three types of these insurance decision makers are risk averse and ambiguity averse. In addition, groups appear to be influenced in their premium-setting decisions by specific reference points such as expected loss and the concern with insolvency. This behavior is consistent with a growing analytical and empirical literature in economics and decision processes that investigates the role that uncertainty plays on managerial choices. Improved risk-assessment procedures and government involvement in providing protection against catastrophic losses may induce insurers to reduce premiums and broaden available coverage.This article is part of a larger effort supported by the National Science Foundation on The Role of Insurance, Compensation, Regulation, and Protective Behavior in Decision Making about Risk and Misfortune. We greatly appreciate the many helpful comments and suggestions by our colleagues on the project: Jon Baron, Colin Camerer, Neil Doherty, Jack Hershey, Eric Johnson, and Paul Kleindorfer.
