In policy research a frequent aim is to estimate treatment effects separately by subgroups. This endeavor becomes a methodological challenge when the subgroups are defined by post‐treatment, rather than pre‐treatment, variables because if analyses are performed in the same way as with pre‐treatment variables, causal interpretations are no longer valid. The authors illustrate a new approach to this challenge within the context of the Infant Health and Development Program, a multisite randomized study that provided at‐risk children with intensive, center‐based child care. This strategy is used to examine the differential causal effects of access to high‐quality child care for children who would otherwise have participated in one of three child care options: no non‐maternal care, home‐based non‐maternal care, and center‐based care. Results of this study indicate that children participating in the first two types of care would have gained the most from high‐quality center‐based care and, moreover, would have more consistently retained the bulk of these positive benefits over time. These results may have implications for policy, particularly with regard to the debate about the potential implications of providing universal child care. © 2002 by the Association for Public Policy Analysis and Management.  相似文献

The 1996 Personal Responsibility and Work Opportunity Reconciliation Act requires welfare recipients to look for work and has made it more difficult for nonworking recipients to remain on the welfare rolls. In addition, the economic boom of the 1990s and changes in federal and state policies have raised the net income gain associated with moving from welfare to work. This paper analyzes data from a panel survey of single mothers, all of whom received welfare in February 1997. In 1999, those who left welfare and were working had a higher household income and lower poverty rate, experienced a similar level of material hardship, engaged in fewer activities to make ends meet, and had lower expectations of experiencing hardship in the near future than did nonworking welfare recipients. Estimations of fixed‐effect regressions of income that control for both observable and unobservable time‐invariant characteristics show that monthly net income increases by $2.63 for every additional hour of work effort. About 60 percent of the observed monthly income difference between wage‐reliant and welfare‐reliant mothers can be attributed to differences in their work effort. Thus, after welfare reform, it does pay to move from welfare to work. © 2002 by the Association for Public Policy Analysis and Management.  相似文献

Two Taiwanese republics have been mentioned in this paper, namely, the Republic of Taiwan (ROT) and the Republic of Taiwan (ROT). The ROT briefly existed in 1895, and the ROT is yet to be created. Two Chinese republics have also been discussed, the Republic of China (ROC), which was created by Dr. Sun Yat‐sen in 1912, and the Republic of China (ROC) or Zhonghuagongheguo, which may be created by the Chinese Communists with the blessings of Deng Xiaoping. If Beijing, indeed, changes its national title from the People's Republic of China (PRC) to the ROC, Taipei's formal ties with other capitals may have to come to an abrupt end. Such a move will also shatter the hope of those Taiwan independists in creating a new country in Taiwan or frustrate those who are for the Taiwanization of the ROC. However, it will also mean the “end” of Communism in China, if one does not believe in Marxist Utopia.  相似文献

In post‐modern society cultural cleavages are becoming at least as relevant as socio‐economic ones. They can only be properly researched by the survey method, which opens up a whole new area for both micro and macroanalysis. So, first, we pinpoint some of the main problems of research into value orientations. Second, we suggest a new analysis of attitudes towards gender and homosexuality, employing both micro and macro data. One key finding here is that attitudes towards gender and homosexuality are linked at the micro level, which explains some of the saliency of gender and homosexuality as a new emerging cleavage in advanced societies. At the macro level, the main finding is that attitudes towards gender and homosexuality are strongly embedded in cultural or civilisational differences among countries. The evidence suggests therefore that these attitudes do constitute a new cleavage in advanced societies.  相似文献
