The study examines whether the income opportunities of Native Americans over the 1980s improved in response to stronger aggregate job growth or deteriorated in response to declining wage and employment opportunities, particularly for the less-skilled. Using data from the 1980 and 1990 US Census on individuals aged 16–64, a methodology is presented to analyze the effect of changes in the income distributions of Native Americans and whites on the average Native American-white income ratio. Oaxaca-type decompositions are also used to yield insights into the role of economy-wide as opposed to Native American-specific effects on changes in income, hourly earnings and annual hours employed over the period. The study concludes that the economic circumstances of Native American men and women further deteriorated relative to whites over the decade, chiefly due to the declining valuation given to Native American human capital, particularly for men. An important finding of the study is the role of economy-wide vis-à-vis native-specific effects: almost all of the adverse movements in average hourly earnings against Native Americans can be attributed to changes in economy-wide hourly earnings structures (with the least-skilled being paid less), whereas the large fall in relative annual hours is due to changes specific to Native Americans.  相似文献

Summary In this article a ‘socio-historical’ method of analysisand intervention in social work will be developed, illustratedby an example drawn from social work with families, the programknown in France as Action Educative en Milieu Ouvert. Our purposeis to support and encourage what we call ‘low key practices’,which refers to practices in which social workers within theexisting structures of so-called ‘individual social work’attempt to explain the social struggle taking place in the situationsthey are dealing with.  相似文献

Random telephone interviews of organizations reveal that, contraryto popular belief, organizations do have opinions and that suchopinions can be obtained by use of traditional survey methods.In addition, when compared with a sample of individuals, theopinions of organizations differ from those of individuals onsome questions and not on others. It is suggested, therefore,that the omission of organizations from public opinion researchmay result in a misrepresentation of reality.  相似文献

In a recent article in this Journal Browning and Culbertson (hereafter B-C) extended the theoretical investigation of the predicted effects of maximum price controls to the competitive firm and deduced an excess capacity result. In this note we extend their analysis to derive long-run adjustment paths for the industry for changes in market demand or control prices. The importance of such an extension is that the relevant industry adjustment path is different depending on whether one considers changes in the control price through such mechanisms as cost pass-throughs or through changes in industry demand. To make this extension meaningful, however, we must first consider the link between the firm and market diagrams in B-C's model. Section I is devoted to the analysis. Section II offers some concluding remarks.  相似文献

Child care denotes any arrangement used by a working parent for care of a child, including self-care. This paper is concerned with the factors that influence the demand for market modes of child care by two parent families with working mothers. An econometric model is specified that relates the demand for child care to price, income, and other economic variables. Because of the discrete nature of the child care decision, the multinomial logit probability model is used to analyze the data. The empirical results suggest that the demand for child care is sensitive to both prices and income.  相似文献
