Do participants make decisions consistent with risk-value tradeoffs? One hundred and five undergraduate business students made risk and preference judgments about lottery pairs in a series of paper surveys. The data indicate that the participants’ responses were generally consistent with the key assumptions of risk-value models, but that some extensions of the theory would improve this consistency. In particular, we find that modifying the risk assumptions of the risk-value theory so they are consistent the concept of the reflection of the risk attitude in the domains of gains and losses increases the agreement between the theory and the participants’ responses. 相似文献

What is Loss Aversion? 总被引:3,自引:0,他引:3
A behavioral definition of loss aversion is proposed and its implications for original and cumulative prospect theory are analyzed. Original prospect theory is in agreement with the new loss aversion condition, and there utility is capturing all effects of loss aversion. In cumulative prospect theory loss aversion is captured by both the weighting functions and the utility function. Further, some restrictions apply for the weighting functions involved in the latter model.We are indebted to Michèle Cohen and Peter Wakker for helpful comments. The suggestions of an anonymous referee have improved the presentation of the paper. 相似文献

In this note we provide new results of interest in the portfolio choice problem when the risky opportunities are correlated:
for a general vector (X1, X2,..., Xn) of risky opportunities we give new conditions for stochastic comparison among different portfolios choices and new necessary
and sufficient conditions to characterize the portfolio which gives the maximal expected utility. 相似文献

Analyses of the economic consequences of divorce have emphasized the negative effect of divorce for women. For men, consequences
of divorce are most often believed to be social or psychological. This is not consistent with an economic literature showing
the positive effects of marriage on men’s wages. Using a nationally representative life-history survey among men in the Netherlands,
this paper reanalyzes the possible negative effects of a divorce for the careers of men. Complete life histories provide information
on upward and downward occupational mobility as well as on unemployment and disability. Multivariate event history models
show that after divorce, men experience an increased chance of becoming downwardly mobile, an increased chance of becoming
unemployed, and an increased chance of becoming disabled. Additional analyses are done to assess whether these effects are
spurious, due to the influence of earlier problems that men experienced in their lives, as measured by indicators of employment
problems, health problems, and problems in social relationships. While these variables have an effect on the future career,
they are not strong enough to eliminate the divorce effect. Implications are discussed for different theoretical hypotheses
about the importance of marriage and divorce for men’s employment.

We investigated the sensitivity of measures of cognitive ability and socioemotional development to changes in parents' marital status using data from the National Longitudinal Survey of Youth, 1979. We used several scores for each assessment, taken at different times relative to parents' marital transitions, which allowed us to trace the effects starting up to five years before a parent's change in marital status and continuing for up to six years afterward. It also allowed us to correct for the unobserved heterogeneity of the transition and nontransition samples by controlling for the child's fixed effect in estimating the time path of his or her response to the transition. We found that children from families with both biological parents scored significantly better on the BPI and the PIAT-math and PIAT-reading assessments than did children from nonintact families. However, much of the difference disappeared when we controlled for background variables. Furthermore, when we controlled for child fixed effects, we did not find significant longitudinal variation in these scores over long periods that encompass the marital transition. This finding suggests that most of the variation is due to cross-sectional differences and is not a result of marital transitions per se. 相似文献

This research examines excess mortality among American veterans age 70 years or older during a two-to-three year interval
from 1993/94 to the end of 1995. Using a structural hazard rate model, we analyzed data on a sample of respondents age 70
or over from the Survey of Asset and Health Dynamics among the Oldest Old (AHEAD). We found that at age 70, older veterans
have a slightly higher death rate than their nonveteran counterparts, implying a mortality crossover right before this age.
Such excess mortality among veterans increases considerably with age, when other factors are held equal. The direct and indirect
effects of veteran status on mortality by means of physical and mental health mostly perform in opposite directions, and such
effects vary greatly in magnitude and direction as a function of age. The intervening effects of physical and mental health
status decrease substantially with increasing age. Many of the mechanisms inherent in the excess mortality among older veterans
are not captured by variations in their health status, especially among the oldest-old. A more extensive study on this topic
is urgently needed. 相似文献

The role of public health improvements in health advances: The twentieth-century United States 总被引:2,自引:0,他引:2
Mortality rates in the United States fell more rapidly during the late nineteenth and early twentieth centuries than in any other period in American history. This decline coincided with an epidemiological transition and the disappearance of a mortality "penalty" associated with living in urban areas. There is little empirical evidence and much unresolved debate about what caused these improvements, however. In this article, we report the causal influence of clean water technologies--filtration and chlorination--on mortality in major cities during the early twentieth century. Plausibly exogenous variation in the timing and location of technology adoption was used to identify these effects, and the validity of this identifying assumption is examined in detail. We found that clean water was responsible for nearly half the total mortality reduction in major cities, three quarters of the infant mortality reduction, and nearly two thirds of the child mortality reduction. Rough calculations suggest that the social rate of return to these technologies was greater than 23 to 1, with a cost per person-year saved by clean water of about dollar 500 in 2003 dollars. Implications for developing countries are briefly considered. 相似文献

This study investigates the relationship between environmental degradation and men and womens family size preferences and subsequent reproductive behaviors in Nepal. We draw on unique environmental data at the local level, household and individual-level survey data and individuals reproductive behavior over a 3 year time period in Western Chitwan Valley, Nepal. Results from Ordinary Least Squares (OLS) and logistic regression models show that poorer environmental quality and greater reliance on publicly owned natural resources are associated with higher family size preferences and higher rates of pregnancy. The analyses provide support for the vicious circle argument that environmental degradation can lead to rising population growth via positive effects on fertility. As environmental conditions decline and when households rely on public lands for natural resources, men and women desire larger family sizes and women are more likely to get pregnant in the near future. 相似文献

Cultural differences in response to the Satisfaction With Life Scale (SWLS) items is investigated. Data were fit to a mixed
Rasch model in order to identify latent classes of participants in a combined sample of Norwegians (N = 461) and Greenlanders (N = 180). Initial analyses showed no mean difference in life satisfaction between the two subsamples. After transforming the
ordinal raw scores into interval scales while simultaneously controlling for response bias, different results appeared. First,
approximately 80% of the participants in the Greenlandic subsample fit a latent class with a large degree of random responding
to the SWLS. Second, relative to the Norwegians, more Greenlanders were using extreme categories in responding to the SWLS.
After statistically controlling for this tendency, Norwegians were in general more satisfied with their lives than Greenlanders.
Third, Greenlanders who belonged to one specific latent class were more satisfied than their Norwegian counterparts. A salient
feature of this class was the relative unwillingness of respondents to change the circumstances of their lives if they were
given such an opportunity. The above results are a reminder of the care that must be used in analyzing survey data across
cultures. The analytical strategy applied in the article offers an improved approach to handling such data. 相似文献

Structural Analysis of a Consumption-Based Stratification Indicator: Relational Proximity of Household Expenditures 总被引:1,自引:0,他引:1
This paper proposes a new analysis of consumption inequality using relational methods, derived from network images of social structure. We combine structural analysis with theoretical concerns in consumer research to propose a relational theory of consumption space, to construct a stratification indicator, and to demonstrate its analytical efficacy with aggregate consumption data. This allows us to emphasize the multi-dimensionality of the relationship between social groups and consumption patterns in the context of a stratification perspective. We utilize the concept of structural equivalence, derived from network models of social structure, to recover relational proximity between social groups and between consumption categories. Additionally, we use relational proximity to construct a new indicator of consumption hierarchy and we test its predictive ability in estimating consumption behavior. We discuss the theoretical implications of our findings for a spatial theory of stratification, as well as possible directions for future research. 相似文献
