Pareto utility

In searching for an appropriate utility function in the expected utility framework, we formulate four properties that we want the utility function to satisfy. We conduct a search for such a function, and we identify Pareto utility as a function satisfying all four desired properties. Pareto utility is a flexible yet simple and parsimonious two-parameter family. It exhibits decreasing absolute risk aversion and increasing but bounded relative risk aversion. It is applicable irrespective of the probability distribution relevant to the prospect to be evaluated. Pareto utility is therefore particularly suited for catastrophic risk analysis. A new and related class of generalized exponential (gexpo) utility functions is also studied. This class is particularly relevant in situations where absolute risk tolerance is thought to be concave rather than linear.     

Does the online collection of ego-centered network data reduce data quality? An experimental comparison

We analyze whether differences in kind and quality of ego-centered network data are related to whether the data are collected online or offline. We report the results of two studies. In the first study respondents could choose between filling out ego-centered data through a web questionnaire and being probed about their network in a personalized interview. The second study used a design in which respondents were allocated at random to either online or offline data collection. Our results show that the data quality suffers from the online data collection and the findings indicate that this is the consequence of the respondents answering “mechanically”. We conclude that network researchers should avoid to simply copy traditional network items into a web questionnaire. More research is needed about how new design elements specific for web questionnaires can motivate respondents to fill out network questions properly.     

An Exploratory Study of Religion and Trust in Ghana

Based on individual-level data from 2008 Afro-barometer survey, this study explores the relationship between religion (religious affiliation and religious importance) and trust (interpersonal and institutional) among Ghanaians. Employing hierarchical multiple regression technique, our analyses reveal a positive relationship between religious affiliation and both measures of trust among Ghanaians. A positive relationship between Catholic, Protestant, Muslim, Pentecostal/Evangelical faiths and interpersonal trust compared to non/traditional religion are detected. The data also reveal that upon controls, only Catholic and Pentecostal/Evangelical show significant positive effect on institutional trust among Ghanaians compared to non/traditional religion. It is worth noting that religious importance does not significantly predictor of neither interpersonal nor institutional trust among Ghanaians. The overall effect of religion on trust is weak, and weaker for institutional trust. Most of the difference relates to the difference between world religions and traditional religions. Place of residence, political affiliation, region of residence, ethnicity, and education are significant nonreligious predictors of both institution and interpersonal trust among Ghanaians. The findings further show that whereas age significantly influences only interpersonal trust, gender, life satisfaction, media exposure, sense of corruption, and sense of unfair treatment are significant factors molding institutional trust among Ghanaians. Policy implications of the study are discussed, emphasizing the need to incorporate religious organizations in efforts aimed at boosting interpersonal and institutional trust among Ghanaians. Religious-specific trust promotion program is suggested as possible strategy likely to succeed in Ghana. The need for more detailed studies in this important but ignored area is emphasized.     

Collective Labor Supply and Child Care Expenditures: Theory and Application

In this study we examine the collective labor supply choices of dual-earner parents and take into account child care expenditures. For this purpose we use data of the Flemish Families and Care Survey (FFCS, 2004–2005). The main findings are, firstly, that the supply of paid labor is hardly affected by changes in the prices of child care services. Secondly, child care price effects on the individual labor supplies are much smaller than the wage effects. Thirdly, we find that additional earnings due to an increase in household non-labor income minus the child care expenditures are mainly transferred to the wife.     

Adolescent Adjustment and Patterns of Parents' Behaviors in Early and Middle Adolescence

In this study, we identified unique clusters of parenting behaviors based on parents' school involvement, community involvement, rule‐setting, and cognitive stimulation with data from the Panel Study of Income Dynamics—Child Development Supplement. In early (n=668) and middle adolescence (n=634), parents who provided high cognitive stimulation (i.e., cognitive enrichment parents) or engaged in all parenting behaviors (i.e., engaged parents) had the highest family income, parent education, and percentage of European Americans. Adolescents of cognitive enrichment or engaged parents often evidenced the highest academic and social adjustment. Adolescents whose parents set a large number of rules (i.e., “Rule setters”) or were also heavily involved in the community (i.e., the “Managers” cluster) had the lowest adjustment.     

Some Australian Children's Perceptions of Physical Punishment in Childhood

Despite ratification of the United Nations Convention on the Rights of the Child, children remain the only people in Australia against whom violence may be justified as discipline. This article presents findings from qualitative research conducted in the State of Victoria, in which children were invited to contextualise incidents of physical punishment by describing the experience from different standpoints and reflecting on the feelings and motivations of victims and perpetrators. The research provides new insights into children's experiences of childhood ‘discipline’, as children reveal the physical and emotional impact of being hit by a parent, the futility of ‘physical punishment’, parents’ confusing reactions and children's awareness of double standards. Children suggest more positive ways to communicate and to resolve conflict, and provide insightful comments that have the potential to enlighten adults’ thinking about the issue.     

The Role of Marital Status and Age on Men’s and Women’s Reactions to Touch from a Relational Partner

Prior research has consistently documented differences between men’s and women’s reactions to being touched by other people. One of the more interesting findings in this literature is the apparent role of marital status in dramatically altering these sex differences in reactions to intimate touch. Unmarried men tend to respond more favorably to intimate touch than unmarried women do, but this difference is reversed among married people. However, research that documented this effect has potentially confounded marital status with age. Participants in this investigation were 305 adults, ranging in age from 18–69. They completed an extensive survey of their reactions to touch to various body regions from a significant other. Results indicated that men had uniformly more positive reactions to intimate touch than women did. For non-intimate touch, the sexes were more comparable in their reactions. This investigation once again documented a disordinal sex by marital status interaction. Unmarried men had generally more positive reactions to touch than unmarried women did and this pattern was reversed among married participants. When statistically controlling for participants’ age, these interactions were still evident.
