In this article we analyze the risk attitude of a group of heterogeneous agents and we develop a theory of comparative collective risk tolerance. In particular, we characterize how shifts in the distribution of individual levels of risk tolerance affect the group’s attitude towards risk. In a model with efficient risk-sharing and two agents an increase in the level of risk tolerance of one or of both agents might have an ambiguous impact on the collective level of risk tolerance; the latter increases for some levels of aggregate wealth while it decreases for other levels of aggregate wealth. For more general populations we characterize the effect of first-order like shifts (individual levels of risk tolerance more concentrated on high values) and second-order like shifts (more dispersion on individual levels of risk tolerance) on the collective level of risk tolerance. We also evaluate how shifts in the distribution of individual levels of risk tolerance impact the collective level of risk tolerance in a framework with exogenous egalitarian sharing rules. Our results permit to better characterize differences in risk taking behavior between groups and individuals and among groups with different distributions of risk preferences.  相似文献

At-risk adolescents experience troubling levels of depression but there is a dearth of research related to the levels of depression and associated psychosocial problems experienced by adolescent abortion patients. The relationship between depression and 16 other psychosocial life problems is examined in a sample of adolescent pregnancy termination patients. Using the Multidimensional Adolescent Assessment Scale (MAAS), depression and related psychosocial problems are assessed in a sample of 120 U.S. abortion patients ages 14–21. In general, patients scoring above the clinical cutscore for depression also reported higher levels of psychosocial problems in the other areas. Depression was significantly associated with problems with self-esteem, stress, guilt and confused thinking. Implications for practice and research are discussed.  相似文献

Repressive abortion policy in the United States creates undue burdens for groups of vulnerable women, including adolescents, women of color, women living in rural areas, and women with economic disadvantages. Repressive abortion policy creates a two-tiered system of access to reproductive health care that is a particular disadvantage to vulnerable women. In this study, current policy is discussed with examples of such policies outlined in three areas: insurance coverage and Medicaid restrictions, mandatory waiting periods, and mandated state counseling. Social workers' role in policy practice is emphasized in regard to advocacy and abortion policy.  相似文献

The current study examines a secondary data analysis of 3,452 administrative cases from a national abortion fund representing patients who received pledges for financial assistance to pay for an abortion from 2010 to 2015 in the United States, where abortion costs are not covered under federal public health programs. Case data were analyzed to assess patients' geographic origin, and whether or not cases were more likely to originate from states with Medicaid and private insurance restrictions. The anticipated travel distance to the provider and whether or not travel distances had been increasing over time were also examined. Results indicate that the majority of pledges are made to residents of the South, Midwest, states without expanded Medicaid access to abortion, and states that have private insurance restrictions on abortion coverage. Results further indicate that those who receive funding pledges anticipated traveling approximately 225 kilometers (140 miles) on average to access the abortion. This distance increased from 2010 to 2015, with patients seeking second trimester procedures expecting to travel nearly 3 times farther than patients in their first term. Abortion fund patients travel great distances to access an abortion and those distances are increasing over time. It is recommended that policy restricting public funding of abortion be repealed to improve access to abortion not only in the United States, but also in other countries where policy restrictions may impede access to abortion, even when it is legal.  相似文献

The taboos surrounding suicide are especially hard to penetrate when the suicide is that of a child. Concerned with presenting a clear picture, the authors discuss the difficulties in recognizing childhood suicide, presuicidal conditions and behaviors, and methods for prevention.  相似文献

ABSTRACT

The web-push method has been shown to increase web response rates in general public surveys. Response rates from two waves of the Emergency Medical Services for Children Program’s Performance Measures Survey, a state-administered establishment survey, were compared to determine if the second wave's revised, centralized implementation strategy improved response rates and consistency across states. The centralized strategy included the web-push design; a carefully timed contacts; and a three-month timeline. The results of the centralized web-push method included a higher overall response rate for a three-month period (81.0% compared to 56.6%) as well as greater consistency in results across states.  相似文献

ABSTRACT

This article examines the concept of being “easy” as a quality that female caregivers aspire to as they envision their potential care in later life. It draws on data from a qualitative study exploring the significance of caregiving to adult daughters’ perspectives and plans for their own aging. Caregivers’ experiences differ based upon their perception of how easy or difficult it was to care for their loved one. The former exemplifies a positive way to approach aging and the receiving of care. Being easy describes an attitude that these caregivers desired for their own later life.  相似文献

In this article, we show that behavioral features can be obtained at a group level even if they do not appear at the individual level. Starting from a standard model of Pareto optimal allocations, with expected utility maximizers but allowing for heterogeneity among individual beliefs, we show in particular that the representative agent has an inverse S-shaped probability distortion function as in Cumulative prospect theory.  相似文献

Common Learning     
Consider two agents who learn the value of an unknown parameter by observing a sequence of private signals. The signals are independent and identically distributed across time but not necessarily across agents. We show that when each agent's signal space is finite, the agents will commonly learn the value of the parameter, that is, that the true value of the parameter will become approximate common knowledge. The essential step in this argument is to express the expectation of one agent's signals, conditional on those of the other agent, in terms of a Markov chain. This allows us to invoke a contraction mapping principle ensuring that if one agent's signals are close to those expected under a particular value of the parameter, then that agent expects the other agent's signals to be even closer to those expected under the parameter value. In contrast, if the agents' observations come from a countably infinite signal space, then this contraction mapping property fails. We show by example that common learning can fail in this case.  相似文献

We present a theoretical model of health beliefs and behaviors that explicitly takes into account the emotional impact of possible bad news (i.e., illness), ex-ante in the form of anxiety and ex-post in the form of disappointment. Our model makes it possible to explain (simultaneously) a number of anomalies such as ’low’ testing rates, heterogeneous perceptions of risk levels, underestimation of health risk, ostriches and hypochondriacs, over-use and under-use of health services, patient preference for information when relatively certain of not being ill, yet avoiding information when relatively certain of being ill, etc. Our model matches observed patterns both in health beliefs and health behaviors and irrational health beliefs and behaviors can be characterized as the optimal response under a given structure of emotions and preferences.  相似文献
