When parents divorce, child support and visitation must be determined. The 1988 Family Support Act requires all states to have child support guidelines for courts to use in determining child support obligations. However, many divorcing couples arrive at agreements without court intervention, or they simply fail to enforce the court decision ex post. Given that the guidelines provide a starting point for negotiations, couples may be able to find self-negotiated, Pareto-improving solutions. In this paper we model the bargaining process that divorcing couples engage in when coming to agreements on visitation and child support. The model suggests that individuals may arrive at agreements that are Pareto improvements for both parents but that the children's welfare may decline as a result of these self-negotiated settlements. Data from the Stanford Child Custody Study show that the changes made in child support and visitation agreements are consistent with our model in only 30 percent of the cases. Therefore, we consider alternative specifications of the model and show that both significant costs of enforcing the original agreement and alternative assumptions on parental preferences can explain these empirical results.  相似文献

The incidence of pregnancy during adolescence has escalated dramatically in recent years, with an estimated half a million infants born to teenagers each year in the United States. A disproportionately high amount of child abuse and/or neglect is encountered among adolescent parents, underscoring the need for an effective intervention strategy. Short-term psychotherapy may be beneficial in these cases for forging a therapeutic alliance expeditiously and rigorously challenging the patient's resistance. The case described involves alleged abuse by a 16-year-old mother. An intervention was designed to clarify the allegations surrounding the abusive incident, help the mother confront episodes of loss in her own life and overcome feelings of hopelessness engendered by separation from her infant.  相似文献

Several methods exist for the problem of testing the equality of several treatments against the one-sided alternative that the treatments are better than the control. These methods include Dunnett's test, Bartholomew's likelihood-ratio test, the Abelson-Tukey-Schaafsma-Smid optimal-contrast test, and the multiple-contrast test of Mukerjee, Robertson, and Wright. A new test is proposed based on an approximation of the likelihood-ratio test of Bartholomew. This test involves using a circular cone in place of the alternative-hypothesis cone. The circular-cone test has excellent power characteristics similar to those of Bartholomew's test. Moreover, it has the advantages of being simpler to compute and may be used with unequal sample sizes.  相似文献

Given the fragmented structure of child‐care assistance in the United States, it has been difficult to obtain accurate estimates of which families are assisted, through which mechanisms, and at what level. Making use of survey data from New York City, we analyze the distribution of several forms of public child‐care assistance. Results suggest that about 40% of all families with young children receive some form of child‐care assistance. Considering all forms of assistance, the distribution of child‐care help is targeted in both expected and some unexpected ways. Implications of these results are discussed in the context of U.S. child‐care policies governing access and benefit levels.  相似文献

主权原则是国际私法中的一项基本原则。在国际私法中长期以来都存在国家利益优先的倾向,但随着全球化趋势的日益增强,传统国际私法中的主权观已越来越不适应国际民商事交往蓬勃发展的现实。全球化带来的是全球法律文明的趋同化,由此伴随着全球共同利益的产生。国际私法作为处理国际民商事法律冲突的法律部门,必须对这种国际社会利益做出反应,把对人权的尊重和保护作为追求正义价值的基本向度。  相似文献
