Marital disruption and economic well-being: a comparative analysis

Summary.  Though there is a considerable literature concerned with the economic consequences of marital breakdown, there is still substantial disagreement in terms of its magnitude. One of the major problems underlying this debate is how economic well-being is defined. We implement several measures of well-being of monetary and multidimensional nature by using data from the European Community Household Panel. Another issue in this literature concerns selection bias of divorcing couples. We tackle this issue by using a propensity score matching technique combined with a difference-in-differences estimator. Results confirm the importance of the definition of well-being. We find a strong gender bias when using monetary measures but a considerably lower bias, and for some countries non-existent, when using non-monetary indices.     

试论长江经济带交通的协调发展

长江经济带在交通设施建设上存在着发展不平衡、与经济发展不相协调等问题,应以长江干流为主轴,以长江航运建设为重点,加快沿江铁路、公路及其他交通设施的建设,形成快速、配套、畅通的东西向交通大动脉,并配套建设、完善南北纵向辐射铁路和公路等交通设施,以形成高效、畅通、合理的综合立体交通运输体系,从而实现长江经济带交通的协调发展。     

陕西高校与区域经济发展的协调性分析

高等教育与区域经济的协调发展,有助于高等教育与区域经济发展的紧密结合,实现良性互动。从规模和结构两个方面的分析表明：陕西高校与经济发展并没有实现相互促进和良性循环,而是造成了较高的人力资本存量与落后的经济发展并存的现象。鉴于此,今后迫切需要把陕西高等教育发展的重点从规模扩张转移到规模与质量并重上来,加快学科专业结构的调整。     

两岸三地个人所得税制的透析与借鉴

比较研究大陆、台湾、香港在个人所得税制模式选择、税率结构、费用扣除方法及征缴方式上的差异,可以发现大陆现行个人所得税调节作用扭曲的原因。本文认为,改革和完善大陆个人所得税制,不仅要借鉴台湾和香港的经验,还必须从大陆的现实状况出发,着力构建个人所得税制执行的社会基础和配套条件。     

反氢原子能级及光谱的经典定性研究

利用一种带相位因子的经典屏蔽Coulomb势,采用经典分析方法对反氢原子的能级和光谱给出了预言性的描述,结果发现其能级与光谱同氢原子有较大区别。在反氢原子中主量子数n小于1的分数值且正电子由基态跃迁到激发态时才产生光谱,与氢原子发光机制正好相反。     

区域产业投入优化的熵权系数模型研究

针对区域产业投入的优化问题,不仅考虑到投入的经济效益,同时也考虑了投入的社会效益和生态效益,综合主观赋权法和客观赋权法,建立熵权系数模型,以确定各产业的最优投入,并举例说明模型的应用.

Inequality and negative income

Summary This note deals with some problems in the measurement of inequality when negative incomes are allowed. A new axiom is defined, called the Greatest Gets More axiom. Using this axiom it can be shown that the properties of some inequality measures depend on whether there are negative incomes or not. In this paper, for the intermediate measures of Eichhorn and the centrist inequality measures of Kolm a threshold value is given above which the Greatest Gets More axiom holds. I am indebted to two anonymous referees for their helpful comments.     

掺杂半导体中孤立杂质能级的研究

提出一种计算掺杂半导体中孤立杂质能级的方法,该方法建立在密度函数理论基础之上。在应用时只需考虑杂质原子所在处的电子密度状态,对所研究对象的对称性没有特别的要求。在低掺杂浓度下,理论计算结果与实验结果基本一致。     

The role of perception in the intention to change the family financial situation

The study investigates factors associated with the individual intentions to change the family financial situation of 337 farm respondents. The hypotheses are that intentions to change are influenced by (a) resource flexibility or constraints existing at the time of the decision situation, including off-farm employment, education, age, and household size, and (b) perceptual factors of perceived income adequacy, locus of control, degree of discrepancy between standard and level of the family financial situation, and dissatisfaction or satisfaction with the discrepancy. Older respondents and those experiencing more external control are less likely to intend to change. Younger respondents and those who perceive their incomes as more adequate are more likely to perceive that they have control over their situation. The lower the perceived income adequacy, the greater the discrepancy between standard and level of the family financial situation and the lower the satisfaction with the discrepancy. Significant indirect effects were consistent with theoretical expectations.Research was supported by the Minnesota Agricultural Experiment Station Projects 52-055, 52-054, and 52-058 and the Minnesota Extension Service. The authors wish to thank Jean W. Bauer, Ph.D., for research collaboration and Susan Keskinen and Cathy Schultz for research assistance.Her research interests include social, economic, and technical decision processes, discrepancies between standards and levels, and the interrelationship of work and family roles, particularly for farm women. Her Ph.D. is from Iowa State University.Her research interests in family resource management theory include social decision making processes and social decision rules, family life quality, and the economic consequences of divorce. Her Ph.D. is from Michigan State University.
