The paper tests the hypothesis that private transfers can be explained by the existence of self-enforcing family constitutions prescribing the minimum level at which a person in middle life should support her young children and elderly parents. The test is based on the effect of a binding credit ration on the probability of making a money transfer, which can be positive only in the presence of family constitutions. Allowing for the possible endogeneity of the credit ration, we find that rationing has a positive effect on the probability of giving money if the potential giver is under the age of retirement, but no significant effect if the person is already retired. This appears to reject the hypothesis that transfer behavior is the outcome of unfettered individual optimization on the part of either altruistic or exchange motivated agents, but not the one that individuals optimize subject to a self-enforcing family constitution. The policy implications are briefly discussed.

In this paper we explore the relationship between English language proficiency and earnings in South Africa, using new data from the first wave of the National Income Dynamics panel survey of 2008. Much of the literature on this topic has studied the impact on earnings of host country language acquisition among minority groups of immigrants to developed countries. In our study we analyse the returns to language skills in a developing country context where the dominant language of business, government and education is that of the former colony, although not more than one percent of the African majority population group speaks English as their home language. Our findings suggest large returns among Africans to reading and writing English very well, and particularly among those who have a tertiary education. We also briefly consider the implications of these results for language and education policy in South Africa in the post-apartheid period.  相似文献

It has been demonstrated that craving for gambling is associated with anxiety and depression in pathological gamblers. Exercise has been shown to reduce anxiety and depression, as well as positively influence abstinence rates in individuals with substance use disorders. In this study, we examined the impact of a physical activity program in 33 pathological gamblers. We also analyzed the association between craving and plasmatic levels of stress hormones (adrenocorticotropic hormone, cortisol, and prolactin). The program involved eight 50-min sessions. Craving was assessed 24 h before, immediately before, and immediately after each session, as well as on a weekly basis. Before and after the program, we evaluated gambling behavior, depressive symptoms, anxiety, and plasma levels of stress hormones. We identified a significant reduction in craving following each session and at the end of the program. There was improvement in anxiety, depressive symptoms, and gambling behavior. The post-session reduction in craving was accompanied by post-program reductions in craving and anxiety but not by a post-program reduction in depressive symptoms. The craving reduction was associated with a variation in prolactin levels but not with variations in levels of cortisol or adrenocorticotropic hormone.  相似文献

In this article, Object-Oriented Bayesian Networks (OOBN) are proposed as a tool to model measurement errors in a categorical variable due to respondent. A mixed measurement error model is presented and an OOBN implementing such a model is introduced. The insertion of evidence represented by the observed value and its propagation throughout the network yields for each unit the probability distribution of the true value given the observed. Two methods are used to predict the individual true value and their performance is evaluated via simulation.  相似文献

Hierarchical spatio-temporal models allow for the consideration and estimation of many sources of variability. A general spatio-temporal model can be written as the sum of a spatio-temporal trend and a spatio-temporal random effect. When spatial locations are considered to be homogeneous with respect to some exogenous features, the groups of locations may share a common spatial domain. Differences between groups can be highlighted both in the large-scale, spatio-temporal component and in the spatio-temporal dependence structure. When these differences are not included in the model specification, model performance and spatio-temporal predictions may be weak. This paper proposes a method for evaluating and comparing models that progressively include group differences. Hierarchical modeling under a Bayesian perspective is followed, allowing flexible models and the statistical assessment of results based on posterior predictive distributions. This procedure is applied to tropospheric ozone data in the Italian Emilia–Romagna region for 2001, where 30 monitoring sites are classified according to environmental laws into two groups by their relative position with respect to traffic emissions.  相似文献

This article provides a summary of the author’s research on human smuggling in Austria comparing migrants from Former Yugoslavia and the Russian Federation. The project’s primary intent was to collect more detailed information on migrants seeking asylum in Austria and their use of smuggling services to leave their home countries, including detailed information on demographics, force or threat of force by smugglers, routes and methods of transportation, costs of smuggling, payment methods, and deeper perceptual questions regarding the flight. Another central premise of the article discusses how current distinctions between human smuggling and human trafficking are arbitrary in many regards.  相似文献

This paper studies the economic implications for mothers of the changes in child custody law from maternal preference to joint custody using the 1960–2000 Census Public Use Micro Sample (IPUMS). Variation in the timing of the joint custody reform across states provides a natural experimental framework to study the causal effect of shared custody on mothers’ economic outcomes. The results show that only single mothers experience a decrease in earnings as a consequence of the adoption of the joint custody law, exposing them to a higher risk of poverty. The paper discusses a possible explanation for these findings, namely that the higher child support payment the mother receives from the non-custodial father in case of joint custody might discourage her from looking for high paid jobs or investing in her career.  相似文献

The rising share of women in college with dependent children and growing emphasis on two‐generation policies for reducing socioeconomic inequality have galvanized research aimed at determining whether mothers' increased education can improve their and their children's well‐being. Yet as part of this effort, scholars have overlooked signs that mothers' college enrollment may not be unequivocally good for families. This research brief aims to bring greater attention to this side of the story. The authors analyze time diary (2003–2015) and well‐being data (2010, 2011, 2013) from the American Time Use Survey. The authors find that mothers in college experience a time squeeze that limits their time in caregiving, self‐care, and work, on one hand, and school‐related activities, on the other. This time squeeze may explain why mothers enrolled in college (compared with mothers who were not in school) also reported less happiness and more fatigue during activities with their children.  相似文献

The authors argue, in line with recent research, that operationalizing gender ideology as a unidimensional construct ranging from traditional to egalitarian is problematic and propose an alternative framework that takes the multidimensionality of gender ideologies into account. Using latent class analysis, they operationalize their gender ideology framework based on data from the 2008 European Values Study, of which eight European countries reflecting the spectrum of current work–family policies were selected. The authors examine the form in which gender ideologies cluster in the various countries. Five ideology profiles were identified: egalitarian, egalitarian essentialism, intensive parenting, moderate traditional, and traditional. The five ideology profiles were found in all countries, but with pronounced variation in size. Ideologies mixing gender essentialist and egalitarian views appear to have replaced traditional ideologies, even in countries offering some institutional support for gendered separate spheres.  相似文献

This study examines whether the length of auditor-client-relationship affects audit quality. It is motivated by recent calls for mandatory auditor rotation in Europe which are based on concerns that a longer auditor tenure reduces audit quality. Earnings management is used as proxy for audit quality. It is measured by the firms’ success to achieve earnings benchmark targets. A situation in which an abnormal high proportion of firms just meet the benchmark and an abnormal low proportion of firms just miss the benchmark is interpreted as earnings management. Analysed benchmark targets are the reporting of small profits (loss avoidance) and the reporting of small positive earnings increases. Multivariate analyses indicate a higher success for benchmark beating with longer auditor tenure. This result suggests that, in the current environment, mandatory limitations on the length of auditor-client-relationship could result in higher audit quality.  相似文献
