Female fertility history and mid-late-life health: Findings from China

China’s middle-aged and older women suffer from poorer health than men. Using national baseline data from the China Health and Retirement Longitudinal Study (CHARLS), a survey conducted from 2011 to 2012, this article applies logistic models to investigate the association between female fertility history (parity, early childbearing, late childbearing) and middle-aged and late-life health. We find that parity is related to the mid-late-life health of women. Women with four children or more are more likely to suffer from activities of daily living (ADL) impairment and poorer self-rated health than those with one to three children. Early childbearing is associated with ADL impairment; however, the correlation is mediated by socioeconomic status. Early childbearing is related to self-rated health in later life by an indirect-only mediation effect via educational attainment and personal income.     

Women's Marriage Behavior Following a Premarital Birth in Sub‐Saharan Africa

This study examines the relationship between premarital childbearing and the timing of women's entry into their first marriage in sub‐Saharan Africa. The study shows that African women who have a premarital birth generally experience later transitions to marriage than do their childless peers. Although the birth of a child precipitates a quicker transition to marriage initially, unmarried mothers, on average, marry at older ages than their childless peers and remain single for between 2 and 14 years. Evidence from a subsample of countries confirms that the time between having a child and first marriage has lengthened slightly in some countries; however, this reflects mainly the overall trend toward later marriage, rather than a further bifurcation of the marital trajectories of mothers versus childless women. The study raises policy concerns about the welfare of Africa's single mothers and their children.     

保障性住房与新生代农民工城市居留意愿——来自2017年中国流动人口动态监测调查的证据

住房是农民工进入城市、融入城市的安身立命之所,而建设保障性住房(简称“保障房”)是改善农民工居住条件,推进农民工市民化进程的关键举措之一.在此背景下,结合最新的2017年中国流动人口动态监测调查数据,系统考察了保障房对新生代农民工城市居留意愿的影响.研究表明:第一,居住在保障房的新生代农民工比例仍然偏低,意味着针对农民工的保障房建设依然任重道远.第二,相比于租房,保障房对新生代农民工城市居留意愿具有显著正向影响,在加入其他解释变量后,结论保持一致.考虑到模型中潜在的选择性偏误,运用倾向得分匹配法构建反事实框架加以纠正,并通过逆向概率加权法、逆向概率加权回归调整法、调整变量衡量方式等进行稳健性检验,结论依然成立.第三,保障房对新生代农民工城市居留意愿的影响存在代际差异,相比于90后农民工,保障房对80后农民工的影响更明显.由此,提出要发挥保障房在农民工市民化进程中的作用,应当突出保障房建设的多样性与差异化、优先考虑就业居住超五年和80后农民工等方面实施更有利于新生代农民工的住房制度改革举措.     

所为非所想?农户风险管理意愿与行为的悖离分析

实现农户风险管理意愿与行为统一是降低农业风险对农户农业生产负面影响的重要途径。利用2018年东北三省和湖北省种植大户的调查数据,从自然风险与市场风险两方面,对农户风险管理的意愿、行为及其悖离进行分析,并探究形成悖离的原因。研究发现：对于自然风险,大部分农户使用了有效的风险管理工具,但风险管理意愿不高;农户的市场风险管理行为极为少见,与之相悖的是,农户具有较高的市场风险管理意愿。结果表明,风险管理实际行为控制、风险管理执行意愿和风险管理外部环境是影响农户自然风险管理意愿与行为悖离的主要因素;此外,农户对农业保险缺乏了解,以及目前农业保险存在的不足也是导致此悖离的重要原因;风险管理执行意愿和风险管理外部环境是影响农户市场风险管理意愿与行为悖离的主要因素。此外,农户获取信息渠道不足,对市场风险管理工具缺乏了解,甚至存在明显的误解与不信任也是导致农户市场风险管理意愿与行为悖离的重要原因。因此,为了有效实现农户风险管理意愿与行为的统一,应健全农业保险的推广机制,加强市场风险管理的宣传,扩大“保险+期货”的试点,发挥新型主体的带动作用。     

Quality Provision with Heterogeneous Consumer Reservation Utilities

This study examines a firm's quality and price decisions when consumers differ not only in their willingness‐to‐pay for quality but also in their reservation utility for the basic product. We find that while the firm offers lower‐quality products when consumers' valuations for quality deteriorate, the optimal quality may increase with a negative shift in consumers' reservation utilities. We also investigate the optimal price and quality of the products within a vertically differentiated product line when the number of products is exogenously given. The existing literature shows that when consumers differ only in their willingness‐to‐pay for quality, the firm sets the efficient quality for consumers with the highest valuation for quality, whereas the concern for cannibalization pushes down the quality of inferior products. We find that when consumers are heterogeneous in both their reservation utility and valuation for quality, the concern for cannibalization may distort the quality upwards, even for consumers with the highest willingness‐to‐pay for quality. In addition, a low‐quality product may enjoy a higher profit margin than a high‐quality product within the product line.     

基于服务驱动假说的消费者自提包裹选择意愿研究

基于淘宝网买家样本,分析了上门投递服务缺陷、上门投递感知风险与消费者自提意愿的关系,试图在新的认知环境下重新检验服务驱动假说。研究表明,上门投递服务缺陷一方面对消费者自提意愿产生了直接的促进作用,另一方面也通过上门投递感知风险的中介效应施加了间接作用;自提感知价值既在上门投递服务缺陷与消费者自提意愿间发挥了调节作用,又对上门投递感知风险的中介作用产生了调节。根据研究结论,可推测当前阶段下服务驱动假说具有一定合理性,相关企业应当明确自提点服务定位,并且需要调整营销推广思路。     

牧地承包经营权转让意愿影响因素研究——基于农户劳动力配置视角

基于西部3省731户农(牧)户的实地调研数据,从农(牧)户劳动力配置视角分析了牧地承包经营权转让意愿的影响因素。研究结果表明:务牧人口数、近三年务牧消耗、务牧技能水平等对牧地承包经营权转出意愿有显著的负向影响;务工兼牧业人口数、务工技能水平和户均单位土地劳动投入对牧地承包经营权转出意愿有显著的正向影响;务工人口数、户主受教育程度等对牧地承包经营权转让意愿的影响不显著。     

大学生参与社会实践活动意愿实证分析与提升路径

参与社会实践活动对大学生成长成才具有重要现实意义和成效，然而当前社会实践活动大学生的参与率相对较低。在对福建省四所高校大学生参与社会时间活动意愿问卷调查的基础上，就影响大学生参与社会实践意愿的因素进行了实证分析，认为是否为学生干部、是否熟悉参与方式及家人是否支持正是影响大学生参与社会实践的三大要素。相应地，在实际工作中，加强宣传协同优化社会实践环境、改变学生家长教育观念争取支持、创新形式多元筹集经费支持等举措，实为拓宽大学生社会实践参与路径之关健。     

Teen Childbearing and Depression: Do Pregnancy Attitudes Matter?

The relationship between teen childbearing and depression has been extensively studied; however, little is known about how young women's own attitudes toward becoming pregnant shape this association. This study used data from the National Longitudinal Study of Adolescent Health to investigate whether the relationship between teen childbearing and adult depression is moderated by adolescent attitudes toward becoming pregnant. The results showed that although, on average, women who had first births between ages 16 and 19 experienced no more depressive symptoms in adulthood than women who had first births at age 20 or older, the relationship between teen childbearing and adult depression varied significantly based on adolescent pregnancy attitudes. When they had negative adolescent attitudes toward getting pregnant, teen mothers had similar levels of depression as adult mothers, but when they had positive adolescent pregnancy attitudes, teen mothers actually had fewer depressive symptoms than women with adult first births.     

农用承包地流转意愿的实证研究--基于福建省六地市农户问卷调查

从农户意愿角度，以福建省农民的农用承包地为研究对象，对影响农户承包地流转的因素进行分析，通过实地调查和问卷调查的形式收集到影响农户流转承包地的样本数据，并对通过建立二元Logistic模型对各个因素的显著性进行检验。通过实证研究发现，户主受教育程度、户主的职业、农户家庭的人口、家庭的收入主要来源、承包地面积和农户流转承包地的租金水平是农户流转承包地的显著性影响因素，其中户主受教育程度、家庭的收入主要来源、承包地面积和租金水平是正向影响，户主的职业和农户家庭的人口是负向影响。根据研究的结论提出相应的政策建议。
