Life satisfaction and family structure among adolescents in Hong Kong

Relationships between family structure and perceived life satisfaction in overall life and five domains of the Brief Multidimensional Students’ Life Satisfaction Scale, family life, friendships, school experience, myself, and where I live were examined among 4,502 Chinese adolescent secondary school students in Hong Kong. Bivariate analyses showed that economic status was not a significant risk factor, but gender, level of study, and migrant status had to be controlled to examine the life satisfaction-family structure relations. Logistic regression analyses found that in overall life, with adolescents living with two parents as standard for comparisons, adolescents living with mother had similar life satisfaction, but those living with father only, and those with no parents, or single parent with other adults had very much higher risk of life dissatisfaction. Specifically, the risks associated with the adverse family structures were most excessive in the domain of ‘family life’.

新经济地理学视角下的劳动力跨省转移机制研究--以长三角城市群为例

新经济地理学理论认为劳动力出于商品多样性偏好和节约商品运输成本的目的集聚于厂商集聚的地区。文章以长三角城市群为例,利用第六次人口普查数据和NEG模型研究了劳动力流动跨省迁移的影响因素,着重考察了市场潜能对劳动力跨省迁移的作用。研究发现：市场潜能对劳动力跨省迁移有显著的正向效应,从而证明了新经济地理学的“前向联系”;地理距离对劳动力跨省迁移有弱化效应,但没有通过显著性检验;工资水平、就业率、边界效应对劳动力跨省迁移有显著的正向效应。     

Financial Intermediation Modernization in Countries with Transition Economy

During the modern phase of economic reforms directed at the establishment of market economy, many countries with transition economies face the challenge of solving the issue of formation and rational usage of internal sources of financing the real sector of the economy, as well as attracting considerable volume of direct foreign investment. In general, financial market imperfections hold back innovation and growth, and that public policy can complement financial markets. Therefore, the most relevant issue at the present time is the formation of attendant and complex supervision institutions, as well as an exigency of innovative economy governance as mainframe principles for further banking system elaboration and financial sector development in general. We have taken Armenia as a case study for transition economy as far as Armenia is currently in the stage of capital market development through integration into international financial markets.      

AFFECTIVE RESPONSES WITHIN A COMPLEX DECISION-MAKING TASK: THE INFLUENCE OF “PERCEPTUALLY” ILL-STRUCTURED PROBLEMS

The perceptual effects of varying levels of expert advice for potentially improving on strategic decisions were examined in conjunction with goals. The amounts of advice about decision alternatives, as well as assigned goals ranging from “nearly impossible” to “easy,” were manipulated. The task used was complex and functioned perceptually as an “ill-structured” problem. Mixed results indicated that more advice significantly affected satisfaction but advice in general had little influence on effort. On the other hand, as goal difficulty decreased, satisfaction and effort significantly increased. Easy goals were superior to more difficult ones within this perceptually ill-structured decision-making situation.

中国股票市场的"不流动性溢价"现象研究

为了解释中国股票市场出现的“不流动性溢价”现象,根据金融经济学的基本理论:所有承担了系统性金融风险的风险厌恶投资者都要求获得超额的收益。假定收益—风险时间序列服从某个包含流动性补偿的GARCH-M模型;实证检验结果表明理论假设合理,即:股票的超额回报包含不流动性补偿,预期的不流动性与未来市场超额回报正相关,而未预期的不流动性与当期的市场超额回报负相关。     

产品市场竞争程度对企业融资行为的影响

许多研究表明我国上市公司存在较强的股权融资偏好。国内学者根据代理理论认为股权融资过多的企业未能充分利用财务杠杆而使企业绩效下降,而本文主要从产品市场竞争对资本结构影响这一角度来研究上市公司的融资行为。研究发现,上市公司的股权融资偏好和上市公司治理结构不完善、代理问题严重等体制和政策因素有关,但是,激烈的产品市场竞争也是导致企业采用低财务杠杆的重要原因,而且由于这一原因而导致的财务保守行为是合理的,它是企业为避免财务风险提高产品市场竞争能力而采取的战略行为。
