Agricultural economic reforms,gender inequality and poverty in Senegal

In Senegal, as in many developing countries, the agricultural sector plays a key role in the economy. In addition to supplying food, agriculture is the most important source of employment, especially for women. Through the Plan for an Emerging Senegal (PES), the Senegalese government is implementing an ambitious financing plan to improve the productivity of the agricultural sector and enhance employment opportunities for women. Our study assesses the impact of two PES measures (investment subsidies and an increase in production subsidies for the agricultural sectors) on economic growth, women's employment, poverty and inequality using a dynamic computable general equilibrium model linked to a microsimulation model. The results show that both policies have generally positive effects in reducing poverty and gender inequalities. However, investment subsidies in the agricultural sectors have stronger impacts in reducing gender inequality and poverty in the long term.     

社会经济发展与男孩偏好的淡化

本文利用2010年中国人民大学育龄妇女家庭与生育状况调查数据,对男孩偏好弱化现象及导致男孩偏好弱化的社会经济因素进行了研究。研究发现,农业技术和生产工具的进步、农村家庭收入来源中非农收入比例的提高、男孩较高的养育成本、社会保障的完善和人口流动性的增加所导致的人们对“养儿防老”预期的降低以及住房、交通条件的改善等一系列社会经济变化的共同作用,使人们的男孩偏好逐步淡化。     

出生性别比综合治理:有所为,有所不为

从1980年我国出生性别比越过正常值域至今,党和各级政府制订了种种措施进行综合治理,但取得的成效甚微。这一时期我国治理工作的特点有:重视禁止性法律法规的制定,但与之相配套的规章制度比较缺乏;重视目标任务的提出,但落实目标的措施比较缺乏;部门性、专项性规章制度较多,综合性规章制度比较缺乏。今后一段时期内综合治理工作,可以按照避实就虚、避难就易的原则,在大力发展社会经济、建立健全社会养老制度、相关法律法规的制定与完善、加大对两非行为的打击力度等方面有所作为;而在人口生育政策的调整、传统文化的改变等方面有所不为。     

台湾出生性别比的状况分析和对策研究

通过梳理有关台湾的人口资料,首先发现台湾出生性别比的发展呈现出总体偏高的趋势,其产生的原因是多种因素共同作用的结果。其次对台湾治理出生性别比偏高的直接和间接措施进行分析,直接措施是加大对非法性别鉴定的处罚,间接措施是消除不利文化的影响,营造促进妇女发展的社会环境。这些措施最终达到了＂标本兼治＂的目的。最后借鉴台湾治理出生性别比问题的经验和教训,为治理中国出生性别比偏高的问题提供相关对策。     

Migrant networks and the immigrant professional: An analysis of the role of weak ties

Weak ties, particularly those to potential employers, play a more important role than strong ties in the immigration of professionals to the United States. I operationalize network strength through the class of admission variable in the Immigration and Naturalization Service's public use data files,Immigrants Admitted to the United States, 1972–1992. I also examine the differential impact of legislative measures on the availability of strong versus weak ties for four groups of professionals: physicians, nurses, engineers and scientists. Not only do weak ties figure heavily on the immigration experiences of professionals, but those impacts affect women differently than men. Professional women rely more heavily on strong ties than on weak ties when compared with males in their respective professions, with the exception of nursing. These findings suggests a need for further study into the migration experiences of professionals as well as more research into how gendered networks develop among immigrant professionals and how those networks influence (either positively or negatively) immigrant adaptation to United States' society.     

Beliefs About Diet and Health:

Low income older women (N = 20) in South Carolina were recruited from congregate meal sites for qualitative interviews to assess beliefs about general health, physical functioning, and preventive health behaviors. A loosely structured interview guide of topics was used to encourage free expression of informants' ideas. The Ethnograph analysis package was used for data analysis. In response to open-ended questions, the women spontaneously shared their beliefs about diet and health. Implications for health promotion in rural areas are discussed.     

中国育龄妇女生育集中度变化分析——基于“五普”、“六普”数据

新中国成立以来,结束了上千年的封建制度给妇女带来的桎梏,妇女的社会地位有了明显的提升,具体表现在社会活动的参与率有了显著的提高,同时妇女在生育行为方面也发生了巨大的变化。本文利用最近两次中国人口普查数据来分析育龄妇女的生育集中度变化情况,并以此对中国目前TFR很低的现象做了解释,据此推断中国在未来几年的时间,总和生育率在一定程度上会呈上升的变化趋势,但不可能在短期内回升到更替水平。     

从再婚人口的性别差异看城市女性的再婚困境——以北京为例

随着我国婚姻解体数量的增多,再婚也日益普遍。基于北京市人日抽样调查数据和婚姻登记数据的计算结果表明,北京近年来失婚女性的再婚率只有男性的40％左右。通过对再婚人口的婚次、年龄、教育程度和户籍等方面的特征及其匹配特点的分析,可以看到女性在再婚过程中相对男性处于明显的弱势地位,而“男高女低”的婚配模式则是造成城市女性再婚困境的主要原因。     

性别工资差异与工资歧视--基于RIF回归的分解方法

文章采用2012年中国劳动力动态调查数据,利用基于 RIF 回归的分解方法分析性别工资差异,并对各收入分位数上的性别歧视程度进行估量和分解。研究发现：随着收入分位数的提高,特征效应对性别收入差距解释的比重逐渐提高;系数效应带来的性别歧视对性别收入差距解释的比重不断下降,但系数效应依然是造成劳动力性别收入差距的主要原因。教育在消减性别收入差距上的作用减弱,而职业资格、掌握技能耗时、职业性别隔离和签订劳动合同等变量则有助于缩小性别收入差距。     

Frequency domain bootstrap for ratio statistics under long-range dependence

A frequency domain bootstrap (FDB) is a common technique to apply Efron’s independent and identically distributed resampling technique (Efron, 1979) to periodogram ordinates – especially normalized periodogram ordinates – by using spectral density estimates. The FDB method is applicable to several classes of statistics, such as estimators of the normalized spectral mean, the autocorrelation (but not autocovariance), the normalized spectral density function, and Whittle parameters. While this FDB method has been extensively studied with respect to short-range dependent time processes, there is a dearth of research on its use with long-range dependent time processes. Therefore, we propose an FDB methodology for ratio statistics under long-range dependence, using semi- and nonparametric spectral density estimates as a normalizing factor. It is shown that the FDB approximation allows for valid distribution estimation for a broad class of stationary, long-range (or short-range) dependent linear processes, without any stringent assumptions on the distribution of the underlying process. The results of a large simulation study show that the FDB approximation using a semi- or nonparametric spectral density estimator is often robust for various values of a long-memory parameter reflecting magnitude of dependence. We apply the proposed procedure to two data examples.
