Rhetoric and Reality of Economic Self-sufficiency Among Rural,Low-Income Mothers: A Longitudinal Study

This study examined the contributions of maternal labor force participation and marital status on economic self-sufficiency over time for rural mothers. Data were from 174 rural families participating in three waves of data collection in Rural Families Speak. χ ² and multiple logistic regression were utilized. Results revealed only one-third of mothers moved toward economic self-sufficiency over three years. Maternal education, employment status, and weekly work hours were associated with improved economic well-being. Compared to single-parent families, unmarried-couple and married-couple families had increased odds of improving economically. In an analysis of all mothers with partners, married or unmarried, martial status was not significant in economic improvement. Findings suggest the role of marriage in welfare reform for rural families should be reconsidered.

MODELING THE ALLOCATION OF GRADUATE STUDENT FINANCIAL AID

Universities have always competed with one another for the relatively small number of highly qualified students interested in graduate education. This competition has been intensified recently by adverse demographic trends. This paper is concerned with the use of financial aid awards as a means of competition and with allocation of awards so that enrollments are maximized while satisfying academic standards and budget constraints. It also considers the randomness of actual aid disbursements and develops models of incremental aid allocation that increase enrollments but are within tolerance levels for budget overruns.     

我国区域金融发展与经济增长的关系研究——基于面板数据的实证研究

运用1980—2004年间相应经济指标的面板数据对我国东、中、西部经济增长与金融发展进行了实证分析,结果表明,中西部地区更多的依靠信贷规模扩张来推动经济增长,而东部地区更多的依赖于金融效率的提升。     

金融周期、金融波动与中国经济增长——基于省际面板门槛模型的研究

本文应用面板门槛模型,研究了2005-2017年间我国31个省（市、自治区）金融波动对经济增长的影响。研究发现,随着金融周期所处阶段的变化,金融波动对经济增长会产生显著的非对称性双重门槛效应,主要体现为如下两点：首先,金融周期处于膨胀期、平稳期和萧条期时金融波动对经济增长会产生负向影响,但从影响系数值的大小来看,处于膨胀期时最大,是后两者的2倍之多,处于平稳期时最小且并不显著;其次,分区域的稳健性检验表明,金融发展水平高的区域双重门槛值出现得早,且两个门槛值间的区间要比金融发展水平低的区域宽28%。这些结论说明,经济增长对于金融波动的容忍弹性会随着金融周期所处的阶段而变化,金融发展水平的提高会放大经济增长对金融波动的容忍区间,但也会加速金融周期处于膨胀期时爆发金融危机的可能性,这使得当前我国存在着进一步发展金融水平和严控金融风险的矛盾,对此本文也提出了相应的政策建议。     

When is brokerage negatively associated with economic benefits? Ethnic diversity,competition, and common-pool resources

There is a growing body of literature positively linking dimensions of social capital to economic benefits. Yet recent research also points to a potential “dark side” of social capital, where over-embeddedness in networks and the pressures associated with brokerage are hypothesized to constrain actors, having a negative effect on economic outcomes. This dichotomy suggests that context is important, yet the overwhelming majority of existing empirical evidence stems from socially homogenous populations in corporate and organizational settings, limiting a broader understanding of when and how context matters. We advance this discourse to a socially fragmented, ethnically diverse common-pool resource system where information is highly valuable and competition is fierce. Merging several unique datasets from Hawaii's pelagic tuna fishery, we find that network prominence, i.e., being well connected locally, has a significant, positive effect on economic productivity. In contrast, we find that brokerage, defined here as ties that bridge either structurally distinct or ethnically distinct groups, has a significant, negative effect. Taken together, our results provide empirical support to widespread claims of the value of information access in common-pool resource systems, yet suggest that in ethnically diverse, competitive environments, brokers may be penalized for sharing information across social divides. Our results thus contribute to an emerging theory on the fragile nature of brokerage that recognizes its potential perils and the importance of context.     

Migration aspirations of European youth in times of crisis

In recent years, the European Union (EU) passed through a significant economic crisis. All across Europe, European young people are among the groups which are hit hardest, with youth unemployment rates rising to over 50% in member states such as Greece and Spain. In the classical migration literature, it is suggested that such unfavourable economic climate would make people more likely to move abroad. Whereas in press releases we are regularly confronted with stories about South European young adults with tertiary education working in bars in Northern European cities, limited empirical evidence exists as such on the relationship between the recent Euro-crisis and migration aspirations. This paper addresses this gap in the academic literature. Using data from Flash Eurobarometer 395, I investigate which micro- and macro-level characteristics influence migration aspirations of young people across the member states of the EU. The results reveal the importance of individual characteristics and feelings of discontent with the current climate in explaining migration aspirations. Furthermore, I detect a negative relationship of relative welfare levels with migration aspirations, and a positive relationship of the youth unemployment ratio. Together, the results suggest that potential young intra-EU movers are positively selected from the population.

长江经济带软件与信息技术服务业技术创新效率时空演变及影响因素研究

选取长江经济带软件与信息技术服务业相关数据,利用DEA-BCC模型测算软件与信息技术服务业技术创新效率,并借助自然断裂法和Tobit模型分析区域软件业技术创新效率时空演变特征及影响机理。从静态分析结果看,长江经济带软件业技术创新效率在研究期内呈现先升、后降、再升的螺旋上升态势。从动态分析结果看,技术进步是软件业技术创新效率提升的主要原因。软件业技术创新效率在空间分布上有明显的中间凹陷特征,各地区整体技术创新效率明显上升。科技创新水平、产业结构、对外开放水平、信息化水平、人口密度是影响长江经济带软件业技术创新效率的重要因素,且影响程度存在区域差异。     

An Empirical Test of a Neo-Malthusian Theory of Fertility Change

Some neo-Malthusians regard fertility as being kept in check by scarcities and constraints and, conversely, as being raised by economic prosperity. Since out-migration to developed countries and the receipt of food aid from developed countries relax the constraints imposed by a country’s carrying capacity, both will have a positive effect on fertility rates in developing countries. Moreover, better economic prospects will also raise fertility, all other things equal. This article provides an empirical test of these hypotheses derived from a neo-Malthusian theory of fertility change. The results fail to confirm the theory and often contradict it.

试论社会治理背景下政府与市场关系的经济法规制

政府与市场的关系问题是经济法规制的基于问题,如何正确看待政府与市场在经济生态系统内各自的功能及作用,是经济法规制的核心问题。因为这样的认识直接导致了经济立法的体系构建与内容规则。经济法规制是国家实施经济治理与尊重市场调节的基本依据,也是施行经济法治与社会治理的根本前提。所以,从社会治理的背景下来讨论经济法规制的社会经济发展的制度条件及制度生成条件,有利于真正建立和完善经济法规制的体系和内容,从而使得经济法治生态化地融入社会治理的结构体系内,达到优化社会制度以促进经济发展的目的。
