基于CGSS2006调查数据,运用多层线性模型分析方法,揭示了市场化改革对住房不平等程度,以及住房资源分配机制的影响作用。研究表明,在地区层面,地区市场化的推进虽然有效提高居民的住房水平,但在一定时期内也拉大住房资源分配的贫富差距,地区市场化水平与住房不平等程度之间存在倒“U”型曲线关系;在个体层面,体制内外职工的住房差异已不显著,但政治精英在住房资源的占有上更具优势。 相似文献

柯亨认为,马克思主义追求的社会主义理想是消除资本主义的阶级剥削,代之以经济平等和彻底的民主,但是,从历史和现实看,我们都距离马克恩的理想有很大距离。即使作为当前的合理目标是最好的选择,市场社会主义至多仍然是次优的选择。鉴于历史发展的进程要求,即过渡特征,我们必须对结果意义上的各种不平等采取包容政策。但在社会主义机会平等的条件下,收入差异在仅仅反映了不同的收入、闲暇差异时才是可以接受的。社会主义平等并非“机械的平等”或“结果的相同”。 相似文献

Recent research has increasingly focused on how ethnicity operates within labor markets. Due to perceptions of intragroup homogeneity and assumptions that inequality only occurs between majority whites and people of color, most research has neglected intragroup economic inequality. This study examines how skin color, immigration/nativity status, and gender influence wage differentials in Latina/o co‐ethnic jobsites (where workers are the same ethnicity). Using data from the Los Angeles Study of Urban Inequality (LASUI), it is found that there are skin color, immigration/nativity status, and sex wage gaps among Latina/os working in co‐ethnic jobsites. Moreover, illustrating intersectionality, immigrant women and dark‐skinned immigrants suffer from wage gaps in co‐ethnic jobsites. Unexpectedly, some Latinas experience a wage advantage, in comparison with Latinos, which is associated with lighter skin. The author suggests that Latinas are subjected to multiple‐jeopardy situations in which they experience an intersection of inequalities in jobsites saturated by co‐ethnics but that lightness of skin color functions as a form of social capital. Thus, research on the benefits or costs associated with working with co‐ethnics cannot be extended to the entire ethnic group. The conclusion is that for Central Americans and Mexicans, co‐ethnic jobsites are generally forms of segregated employment with limited protection from discrimination. 相似文献

In recent years scholars have identified racial disparities in wealth and home ownership as crucial factors underlying patterns of racial inequality and residential segregation in American metropolitan housing markets. While numerous federal housing policies have been identified as responsible for reinforcing residential segregation and racial inequalities in home ownership, little research has focused on the segregative effects of the Section 235 program. As one component of the 1968 Housing Act, Section 235 was designed to shift the focus of federal housing policy away from dispensing aid to local housing authorities for building public housing to providing direct supply-side subsidies to the private sector to stimulate home ownership for nonwhites and the poor. Archival and census data, government reports and housing analyses, and oral histories and interviews are used to examine the segregative effects of the Section 235 program in Kansas City, Missouri from 1969 through the early 1970s. Findings indicate that while the housing subsidy program allowed a vast majority of participating white families to purchase new housing in suburban areas, most participating African American families purchased existing homes located in racially transitional neighborhoods in the inner city. These findings corroborate recent research showing how the market-centered focus of federal housing policy has impaired the ability of African Americans to accumulate wealth through home ownership and reinforced racially segregative housing patterns. 相似文献

Summary. The paper presents a general strategy for selecting the bandwidth of nonparametric regression estimators and specializes it to local linear regression smoothers. The procedure requires the sample to be divided into a training sample and a testing sample. Using the training sample we first compute a family of regression smoothers indexed by their bandwidths. Next we select the bandwidth by minimizing the empirical quadratic prediction error on the testing sample. The resulting bandwidth satisfies a finite sample oracle inequality which holds for all bounded regression functions. This permits asymptotically optimal estimation for nearly any regression function. The practical performance of the method is illustrated by a simulation study which shows good finite sample behaviour of our method compared with other bandwidth selection procedures. 相似文献

The asymptotic (Pitman) power of the X2 test is investigated for particular classes of alternatives. A simple rule is introduced to identify ‘orthogonal alternatives’, for which the noncentrality parameter can be computed in a very simple way. In the sequel, restricted alternatives are considered and the ARE of the unrestricted test w.r.t. the restricted one is shown to depend only on the numbers of degrees of freedom. The concluding section discusses ‘undetectable alternatives’, i.e. alternatives for which the noncentrality vanishes. 相似文献

This paper establishes the principles that should govern the welfare and inequality analysis of heterogeneous income distributions. Two basic criteria – the equity preference condition and the compensation principle – are shown to be fundamentally incompatible. The paper favours the latter, thereby vindicating the traditional method of dealing with heterogeneous samples. However, inequality and welfare comparisons will usually be well defined only if equivalent incomes are obtained using constant scale factors; and researchers will need to distinguish clearly between inequality of nominal incomes and inequality of living standards. Furthermore, household observations must always be weighted according to family size. 相似文献

Minority ethnic groups have low income in later life from private pensions, partly due to shorter employment records in Britain since migration. Yet disadvantage and discrimination in the labour market, as well as differences in cultural norms concerning women's employment, may lead to persistence of ethnic variation in private pension acquisition. Little is known about the pension arrangements made by men and women in minority ethnic groups during the working life. This paper examines the extent of ethnic disadvantage in private pension scheme arrangements and analyses variation according to gender and specific ethnic group, using three years of the British Family Resources Survey, which provides information on over 97,000 adults aged 20-59, including over 5,700 from ethnic minorities. Both men and women in minority ethnic groups were less likely to have private pension coverage than their white counterparts but the extent of the difference was most marked for Pakistanis and Bangladeshis. Ethnicity interacted with gender, so that Blacks showed the least gender inequality in private pension arrangements, reflecting the relatively similar full-time employment rates of Black men and women. A minority ethnic disadvantage in private pension coverage, for both men and women, remained after taking account of age, marital and parental status, years of education, employment variables, class and income. The research suggests that minority ethnic groups - especially women - will be disproportionately dependent on means-tested benefits in later life, due to the combined effects of low private pension coverage and the policy of shifting pension provision towards the private sector. 相似文献
