Most epidemiological studies agree that economically disadvantaged populations are the groups most vulnerable to mental health problems and report lower quality of life among these populations. However, it appears that access to social support plays a role in protecting against the chronic stress resulting from conditions such as poverty. This study is an attempt to clarify the relative contribution of social support to the quality of life of economically disadvantaged populations in two low-income neighbourhoods of Montreal. A random sample of 417 social assistance recipients were interviewed in the respondents?? homes. The Quality of Life scale used was the Satisfaction with Life Domains Scale. The availability of social support components was assessed using the Social Provisions Scale. Social support measures were entered into a multidimensional model that included a number of variables identified as having a relationship to mental health. Among the 17 variables included in a multiple regression analysis, emotional support and support providing reassurance of worth accounted for most of the variance in the QOL predicted by the model. Psychological distress also accounted for a fair amount of variance in QOL and younger people and people experiencing food insecurity showed a lower QOL. 相似文献

This paper presents empirical evidence and a theoretical foundation in favor of the view that the retirement age decision affects older workers' employment prior to retirement. To the extent that there are search frictions on the labor market, the return on jobs is determined by their expected duration: The time to retirement is then key to understanding older workers' employment. Countries with a retirement age of 60 are indeed characterized by lower employment rates for workers aged 55–59. Based on the French Labor Force Survey, we show that the likelihood of employment is significantly affected by the distance to retirement, in addition to age and other relevant variables. We then extend McCall's job search model by explicitly integrating life‐cycle features with the retirement decision. Using simulations, we show that the distance effect in interaction with the generosity of unemployment benefits and the depressed demand for older workers explains the low rate of employment just before the eligibility age for the Social Security pension. Finally, we show that implementing actuarially fair schemes not only extends the retirement age, but also encourages a more intensive job search by older unemployed workers. (JEL: J22, J26, H55) 相似文献

This paper develops a new concept of separability with overlapping groups—latent separability. This is shown to provide a useful empirical and theoretical framework for investigating the grouping of goods and prices. It is a generalization of weak separability in which goods are allowed to enter more than one group and where the composition of groups is identified by the choice of group specific exclusive goods. Latent separability is shown to be equivalent to weak separability in latent rather than purchased goods and provides a relationship between separability and household production theory. For the popular class of linear, almost ideal and translog demand models and their generalizations, we provide a method for choosing the number of homothetic separable groups. A detailed method for exploring the composition of the separable groups is also presented. These methods are applied to a long time series of British individual household data on the consumption of twenty two nondurable and service goods. 相似文献

This paper considers the effects of multicollinearity on the multiple coefficient of determination and on the standard errors of the estimated regression coefficients. Limiting results are well known for these problems, and some particular cases have been investigated. However, the limiting cases do not explain the nonmonotonic relationships that have been observed in practice. This paper explores these relationships and attempts to provide a unifying graphical explanation that includes the previous results as special cases. Implications for stepwise regression and for the interpretation of any multiple regression involving multicollinear independent variables are discussed. 相似文献

The past forty years have seen a rapid rise in top income inequality in the United States. While there is a large number of existing theories of the Pareto tail of the long‐run income distributions, almost none of these address the fast rise in top inequality observed in the data. We show that standard theories, which build on a random growth mechanism, generate transition dynamics that are too slow relative to those observed in the data. We then suggest two parsimonious deviations from the canonical model that can explain such changes: “scale dependence” that may arise from changes in skill prices, and “type dependence,” that is, the presence of some “high‐growth types.” These deviations are consistent with theories in which the increase in top income inequality is driven by the rise of “superstar” entrepreneurs or managers. 相似文献
