金融市场对我国通货膨胀与收入不平等关系的调节作用分析——基于财富门槛视角

笔者通过构建数理模型,从金融市场财富门槛的角度对我国通货膨胀与收入不平等的关系进行了理论分析。结果发现,一方面,在我国金融市场不发达的现实背景下,形成了规避通货膨胀的财富门槛,财富门槛降低了低收入群体规避通货膨胀的效果,扩大了收入差距;另一方面,通货膨胀又在事实上提高了金融市场的财富门槛,进一步加剧了收入不平等状态。利用我国1978年～2009年时间序列数据,进行Johansen协整检验与Granger因果检验,结果验证了金融市场对我国通货膨胀与收入不平等关系的正向影响作用。     

Job Polarization and Task‐Biased Technological Change: Evidence from Sweden, 1975–2005

In this paper, we show that between 1975 and 2005, Sweden exhibited a pattern of job polarization with expansions of the highest‐ and lowest‐paid jobs compared to middle‐wage jobs. The most popular explanation for such a pattern is the hypothesis of task‐biased technological change, where technological progress reduces the demand for routine middle‐wage jobs but increases the demand for non‐routine jobs located at the tails of the job–wage distribution. However, our estimates do not support this explanation for the 1970s and 1980s. Stronger evidence for task‐biased technological change, albeit not conclusive, is found for the 1990s and 2000s. In particular, there is both a statistically and economically significant growth of non‐routine jobs and a decline of routine jobs. However, results for wages are mixed; while task‐biased technological change cannot explain changes in between‐occupation wage differentials, it does have considerable explanatory power for changes in within‐occupation wage differentials.     

Multiracialism and Meritocracy: Singapore's Approach to Race and Inequality

This paper characterizes Singapore's efforts to tackle the problem of persistent racial inequality in terms of the notion of fair meritocracy. Singapore's race policy attempts to level the playing field through its unique race-based self-help organizations and a comprehensive, racially integrated, public housing program. Individuals are then sorted by the ostensibly objective mechanism of a standardized test based educational system. The social and economic implications of this policy are examined and, using summary data from the 1980 and 1990 censuses, the extent to which Singapore has been successful in creating a fair multiracial meritocracy is assessed.     

Gender and regional inequality in human development: the case of Spain1

In this paper, we present estimates of the Human Development Index and the Gender-Related Development Index in the Autonomous Communities of Spain. Our case study of Spain, a developed country with clear gender and regional differences, demonstrates the importance of adjusting human development indices in accordance with gender discrimination and regional inequalities. We also show the significance of the income component in assessing the development level of women in countries like Spain, where lack of employment or low remuneration are the chief characteristics of women's inequality. Our analysis makes clear that the Gender-Related Human Development Index has limited applicability in developed countries; it also illustrates the need for alternative variables or models to assess inequality in those countries.     

性别收入差异及性别歧视的变化

性别歧视带来的性别收入差异一直备受关注。文章基于吉林省1990-2010年间三期妇女地位的调研数据分析了吉林省的性别工资差异问题,并运用Oaxaca-Blinder对性别收入差距进行了分解。文章对20年间吉林省的性别收入差异进行了横向和纵向的分析,实证研究得到如下结论:性别分割是我国劳动力市场上一直存在的一种现象,性别收入差距总体趋势在扩大;个体特征差异能够在一定程度上解释性别收入差异,现阶段性别收入差异在很大程度上是由于劳动者本身的人力资本水平引起的,是正常合理的范围;歧视仍然是造成性别收入差距的一个原因,女性在获得教育的机会上还是比男性要低,而且女性很难进入到高收入行业和职业,使得在教育方面女性仍然处于不利地位。但是经过20年的发展,对女性的歧视逐步减弱。     

Gender inequalities in ownership and control of land in Africa: myth and reality

Lack of clarity behind measurement and interpretation of statistics on gender and land leads to an inability to clearly articulate a policy response to the potential inequalities faced by women and men. This article sets out to explore, conceptually and empirically, the levels and relative inequalities in land rights between women and men in African countries. The first section of the article engages in a conceptual discussion of how to measure gendered‐land outcomes, what ownership and control mean in different contexts, and why attention to these factors is important for the development of gender and land statistics. The second section of the article systematically reviews existing evidence from microlevel large sample studies to summarize recent trends in land access, ownership, and control by sex. The third section presents new statistics from a variety of nationally representative and large‐scale unpublished data on gender and land in Africa. Results provide not only a nuanced understanding of the importance of measuring land indicators for gendered development in Africa and globally but also new statistics on a variety of land outcomes to aid stakeholders in the discussion of gender‐land inequalities.     

Bivariate income distributions for assessing inequality and poverty under dependent samples

As indicators of social welfare, the incidence of inequality and poverty is of ongoing concern to policy makers and researchers alike. Of particular interest are the changes in inequality and poverty over time, which are typically assessed through the estimation of income distributions. From this, income inequality and poverty measures, along with their differences and standard errors, can be derived and compared. With panel data becoming more frequently used to make such comparisons, traditional methods which treat income distributions from different years independently and estimate them on a univariate basis, fail to capture the dependence inherent in a sample taken from a panel study. Consequently, parameter estimates are likely to be less efficient, and the standard errors for between-year differences in various inequality and poverty measures will be incorrect. This paper addresses the issue of sample dependence by suggesting a number of bivariate distributions, with Singh–Maddala or Dagum marginals, for a partially dependent sample of household income for two years. Specifically, the distributions considered are the bivariate Singh–Maddala distribution, proposed by Takahasi (1965), and bivariate distributions belonging to the copula class of multivariate distributions, which are an increasingly popular approach to modelling joint distributions. Each bivariate income distribution is estimated via full information maximum likelihood using data from the Household, Income and Labour Dynamics in Australia (HILDA) Survey for 2001 and 2005. Parameter estimates for each bivariate income distribution are used to obtain values for mean income and modal income, the Gini inequality coefficient and the headcount ratio poverty measure, along with their differences, enabling the assessment of changes in such measures over time. In addition, the standard errors of each summary measure and their differences, which are of particular interest in this analysis, are calculated using the delta method.     

日本发挥女科技工作者作用的政策及环境的研究

积极开发女性科技人力资源是日本推动科技发展的重要方针。日本政府采取一系列政策措施改善女科技工作者工作和成长环境，构建全社会支持女科技工作者平等发挥作用的氛围，解决女性面临的传统雇佣制度与单位内性别不平等、工作与家庭双重角色冲突与再就业困境、兼顾工作与养育子女的社会环境不够完善等种种困难，使女性科技工作者为实施科学技术立国战略做出贡献。
