This paper explores the idea that the distribution of wealth across social groups fundamentally affects the evolution of economic
inequality. By providing microfoundations suitable for this exploration, this paper hopes to enhance our understanding of
when social forces contribute to the reproduction of economic inequality. In tackling this issue, this paper offers contributions
in two domains. First, it models social capital as a real capital asset with direct use and collateral values. Second, it
extends the concepts of identity, alienation and polarization originally advanced by Esteban and Ray (Esteban, J.M. and Ray,
D.: On the measurement of polarization, Econometrica
62(4) (1994), 819–851). This generalization permits us to consider the multiple characteristics that shape social identity,
inclusion and exclusion. It also underwrites a higher-order measure of socio-economic polarization that permits us to explore
the hypothesis that economic inequality is most pernicious and persistent when it is socially embedded. Holding constant the
initial levels of economic polarization and wealth inequality, we show that higher socio-economic polarization increases subsequent
income and wealth inequality. Far from being a distributionally neutral panacea for missing markets, social capital in this
model may itself generate exclusion and deepen existing economic cleavages. 相似文献

This paper compares a model of labor supply for female heads of household, male heads, and wives. Not only have female-headed households increased significantly as a proportion of all households in recent years, but these households are also more likely to be in poverty than are other households. Yet, the determinants of labor supply for this increasingly important demographic group still are largely unknown. Analyses are performed on a sample of employed female and male heads and wives from the 1976 Survey of Income and Education. We examine the effects of wages, unearned income, number of children, and several other variables on hours worked per year, allowing for race interactions. We find that female heads and wives are similar in the effects of wages on their labor supply, while female and male heads are similar in the positive effect of children. We conclude that although financial need, as evidenced by low wages and children, increases female heads’labor supply, employment in more advantaged, non-female dominated jobs and core industries is needed to promote their full participation in the labor force. 相似文献

Multiple regression analysis traces the effects of two time dimensions (body time as indexed by the female menstrual cycle, and social time as indexed by the calendar week) upon moods, in a prospective study of daily moods over a 40-day period. Positive moods peaked in the ovulatory phase and on weekends, while negative moods peaked in the luteal phase of the menstrual cycle. An individual difference analysis showed that women whose moods are responsive to the menstrual cycle are physically active, socially assertive, sexually orgasmic women for whom the maternal role is important. 相似文献

In this review, the influence of social and work roles are incorporated into a model of retirement adjustment, along with two psychological moderators that may aid the retirement transition. These psychological resources, locus of control and retirement self-efficacy, are those behavioral predispositions that would lead one to engage in proactive strategies for mastering the role changes inherent in the retirement transition. The implications of social and work-related role changes and psychological resources for retirement planning and adjustment are discussed. 相似文献

This article compares two methodologies for modeling and forecasting statistical time series models of demographic processes: Box-Jenkins ARIMA and structural time series analysis. The Lee-Carter method is used to construct nonlinear demographic models of U.S. mortality rates for the total population, gender, and race and gender combined. Single time varying parameters of k, the index of mortality, are derived from these model and fitted and forecasted using the two methodologies. Forecasts of life expectancy at birth, e0 , are generated from these indexes of k. Results show marginal differences in fit and forecasts between the two statistical approaches with a slight advantage to structural models. Stability across models for both methodologies offers support for the robustness of this approach to demographic forecasting. 相似文献

This paper involves a city-level investigation of the 1964–1971 black rioting. It attempts to explain inter-city variations in the severity of the rioting with inter-city variations in black population size, political structure, black-white income inequality, and regional location. The research charts two new areas of inquiry: (1) It is the first study to use data on the entire rioting period (1964–71). (2) Most previous investigators have concentrated on linear hypotheses, e.g., most have posited and tested for a linear relationship between riot activity and black-white economic inequality. However, a review of theoretic commentary on rebellion reveals that some potential relationships should be hypothesized as curvilinear; more specifically, plausible hypotheses can be developed that rebellious activity is highest where economic inequality and political responsiveness are moderate. Such hypotheses are developed and tested. The overall pattern of results supported the posited curvilinear relationships. 相似文献

An experimental procedure was developed to investigate word-learning skills of children who use cochlear implants (CIs). Using interactive play scenarios, 2- to 5-year olds were presented with sets of objects (Beanie Baby stuffed animals) and words for their names that corresponded to salient perceptual attributes (e.g., "horns" for a goat). Their knowledge of the word-object associations was measured immediately after exposure and then following a 2-hour delay. Children who use cochlear implants performed more poorly than age-matched children with typical hearing both receptively and expressively. Both groups of children showed retention of the word-object associations in the delayed testing conditions for words that were previously known. Our findings suggest that although pediatric CI users may have impaired phonological processing skills, their long-term memory for familiar words may be similar to children with typical hearing. Further, the methods that developed in this study should be useful for investigating other aspects of word learning in children who use CIs. 相似文献
