Whereas both the Allais paradox, the first empirical challenge of the classical rationality assumptions, and learning have
been the focus of many experimental investigations, no experimental study exists today into learning in the pure context of
the Allais paradox. This paper presents such a study. We find that choices converge to expected utility maximization if subjects
are given the opportunity to learn by both thought and experience, but less so when they learn by thought only. To the extent
that genuine preferences should be measured with proper learning and incentives, our study gives the first pure demonstration
that irrationalities such as in the Allais paradox are less pronounced than often thought.

This study estimates the effects of children's economic contributions on parents' allocation of time for income-earning activities, care of preschool children, non-income home production, and leisure activities in Ile-Ife, Nigeria. Fathers spent 65% of work time, mothers 20%, and children 15% during the assessment of family time allocation and income contribution. Demographic factors affecting the parents' time for the children include age of parents, age and sex of children and the number of other people living in the household. Economic factors affecting parents' time allocation include education, house value, wealth, and combined income of parents. Major observations noted were the following: 1) children contribute non-negligible amounts of income and time to their families' income-earning activities; 2) they play important roles in non-income home production and child care activities; 3) their presence has a considerable influence on their parent's allocation of time; 4) children appear to stimulate fathers to work longer hours at the expense of leisure; 5) young children reduce mothers' time in income-earning activities and leisure time; 6) older male children substitute for mothers' shorter work time; 7) older female children substitute for mothers' lesser home production time; and 8) older children of both sexes appear to increase mothers' leisure time. 相似文献

ABSTRACTIn 2017, the Israeli government implemented a universal child development account programme – the Saving for Every Child Program (SECP) – which establishes a personal savings account for every Israeli child and provides monthly deposits until the child turns 18. The SECP has the potential to provide substantial assets when children reach adulthood, but the benefits depend on parents’ investment choices. The unique programme’s nature presents opportunities to learn from its implementation. This paper provides a comprehensive overview of the SECP, its legislative history, early findings from its implementation, and recommendations that may improve programme participation and outcomes across population groups. 相似文献

This article will demonstrate how schools of social work can collaborate with community agencies to provide a comprehensive and enriching educational experience for both student interns and participating agencies. An innovative partnership of a state school of social work with community agencies leading to a cutting-edge geriatric field education program is described. Case examples are used to illustrate the benefits of these partnerships, as well as challenges partners overcame in forging and sustaining partnerships. Necessary components of partnership development are detailed. 相似文献

Rural dwelling elders who experience mental health problems often have difficulty finding help since rural communities often lack adequate mental health service providers. This paper reports on the initial phase of a 5-year, interdisciplinary clinical research study that is testing the effectiveness of providing a home delivered, therapeutic psychosocial intervention, aimed at improving the emotional wellbeing and the quality of life of medically frail elders who live in rural communities. In the early phases of this study, the clinical research team encountered a number of interesting and often unanticipated challenges as it attempted to recruit study participants and provide services to them. In this article, we examine these challenges and share what we have learned so far about providing mental health services to elderly persons living in rural environments. 相似文献

Objective. An individual's personal experiences and perception of the collective experience are often linked to political attitudes, especially those concerning the national economy. In this article, we examine whether personal concern about terrorism and perceptions of public concern about terrorism affect attitudes about counterterrorism policies. In addition, we evaluate which factor is the strongest predictor across several counterterrorism policies. Method. We analyze individual‐level survey data collected during the fall of 2001. Results. Our results indicate that perceptions of public concerns are the strongest and most consistent predictor of policy attitudes about terrorism. Conclusion. The implications for theory about perceptions of public opinion and the competing role of personal interest and sociotropic concern are discussed. 相似文献

Objectives. Harris and Sim (2002) recently demonstrated the complexity of lived race by exploring patterns of racial self‐identification. They raised important sociological questions about the role of context in racial self‐identification, but offered an incomplete picture of ethnic fluidity by excluding Hispanics from their analyses. We address this limitation with data on Hispanics from the National Longitudinal Study of Adolescent Health (Add Health). Methods. Our social‐psychological approach, using compositional analysis, focuses on the lived experience of race and ethnicity as qualitatively similar conceptual categories. Results. Informed by the cognitive process of social categorization, we find that considerably more individuals show fluidity in racial and ethnic self‐identification across contexts than suggested by Harris and Sim. Conclusions. Harris and Sim's thesis is even more strongly supported by these findings than in their original analysis, and our findings reinforce their challenge to the assumed stability of racial and ethnic measurement in sociology. We conclude by proposing a change in the measurement of race/ethnicity in America. 相似文献

Objectives. The objectives of this article are to examine the impact of acculturation on the levels of trust in both the national and local governments in a long‐term minority‐majority community and to consider the effect on Mexican Americans' level of trust of long‐term co‐ethnic control of local government. Methods. Ordered probit is applied to measures of local and national political trust derived from the National Election Studies. Data were drawn from a sample of Latino respondents residing in the predominantly Mexican‐American region of south Texas. Independent variables include a language‐based measure of acculturation, a measure of interethnic social interaction, and items dealing with respondents' evaluations of the honesty, efficiency, and beneficiaries of governmental policies. Clarify is then used to estimate the real‐world impacts of these variables. Results. Acculturation has a significant and negative impact on trust in the national government. This effect vanishes, however, at the local level. Moreover, co‐ethnic control of government appears not to be related to trust. Conclusions. Trust in the national government is significantly reduced by acculturation, while trust in local government is unaffected. Moreover, trust in government is not enhanced by co‐ethnic control of the levers of political power. 相似文献
