不完全竞争、破产与企业资本结构选择

不完全竞争条件下破产或破产的可能性对企业资本结构的选择有着重要的影响.破产延缓了企业在下一阶段的投资决策,这种延缓本身的成本并不很高,但由于产品市场是不完全竞争的,因而这种延缓使得破产企业在市场竞争中处于一种策略劣势.企业间最终的均衡结果取决于破产企业固定生产成本的高低:如果固定生产成本较低,那么产品市场上相互竞争的企业之间采用相同的策略,最终的均衡结果是对称的;反之相互竞争的企业之间采取不同的策略--一家企业寻求债权的税收优惠,另一家企业寻求股权的策略效应,最终的均衡结果是不对称的,这也解释了为什么同一个行业中相似的企业之间资本结构有很大的不同.     

Economic Disadvantage,Family Dynamics,and Adolescent Enrollment in Higher Education

This study applies a family process model to the linkage between early economic disadvantage and later enrollment in higher education. Using two waves of data on low‐income youth, the authors found that the attitudes and behaviors of their parents, mostly mothers, mediate the impact of disadvantage on enrollment. Economically disadvantaged parents are less optimistic about their adolescents' educational chances and, in turn, engage less in the proactive parenting that promotes enrollment. The authors also found that parents' perceived efficacy buffers against the more negative consequences of disadvantage that can influence their adolescents' educational trajectories. Group comparisons reveal few differences by gender or ethnicity.

论训诂中的逻辑问题

前人在运用训诂方法训释词义的时候,往往难免在概念、判断和推理等方面出现逻辑错误,而这些又往往与违反思维的基本规律密切相关。训诂在概念方面所出现的逻辑问题,一般表现在内涵与外延不明确这两个方面;在判断方面所出现的逻辑问题,一般表现在把误字当做正字、把衍文当做正文、把虚词当做实词、误动为静或误静为动、把借字当做本字、把引申义当做本义、把联绵词当做两个单词等方面;在推理方面所出现的逻辑问题,一般表现在以偏概全、机械类比和前提不真实等方面;在思维规律方面所出现的逻辑问题,一般表现在违反同一律、违反不矛盾律、违反充足理由律等方面。     

Society's readiness: How relational approaches to well-being could support young children's educational achievement in high-poverty contexts

This paper explores how relational approaches to well-being could support young children's educational achievement in high-poverty contexts. It draws on findings from a qualitative study involving mothers and early years educators living and/or working in a city characterised as one of the most disadvantaged in England. The findings suggest that children's well-being, rather than being merely an individual characteristic or aspiration, is interdependent with their social and material environments, as are the institutions that support them. The paper concludes by calling for a recalibration of early childhood policies away from assessing individual children's ‘school readiness’ to encouraging society's readiness to support everyone's well-being, and consequently that of young children too.     

How parents' income,time and job quality affect children's health and development

The advent of the Global Financial Crisis reminds us that modern epidemiological research has consistently demonstrated links between the socio‐economic circumstances of families and children's health and development. Drawing on data from the Longitudinal Study of Australian Children, this article firstly examines the evidence for intergenerational transmission of socio‐economic disadvantage from parents to young children. It then examines parents' jobs as another source of social inequality. Results confirm that children's healthy development is affected by family income, by parents' hours of work and by the quality of parents' jobs. Job combinations that include long work hours of mothers and fathers and poorer quality jobs are associated with elevated rates of parental mental health problems, less time spent in developmentally important activities with children, and socio‐emotional developmental difficulties for children. The evidence suggests that these effects are greater within low income families. These findings highlight the need for social and economic policies to move beyond simplistic notions of promoting parental workforce participation as a way of reducing the adverse effects of social disadvantage. A more nuanced approach is required that considers the additional impacts of the quality and characteristics of jobs, especially for the parents of young children.

Economic disadvantage,perceived family life quality,and emotional well-being in Chinese adolescents: A longitudinal study

Over three consecutive years, Chinese secondary school students experiencing and not experiencing economic disadvantage (n = 280 and 2,187, respectively) responded to measures of perceived family life quality (parenting attributes and parent-child relational quality) and emotional well-being (hopelessness, mastery, life satisfaction and self-esteem). While participants experiencing economic disadvantage generally had more negative perceptions of parenting quality and parent-child relational quality than did adolescents not experiencing economic disadvantage, the differences were more pronounced for the father-adolescent dyad than for the mother-adolescent dyad. Emotional well-being was also different in adolescents with and without economic disadvantage. Although adolescents experiencing different intensity of economic disadvantage differed on some paternal parenting processes, no related differences were observed for other measures of family life quality and emotional well-being. The present study fills the research gap pertinent to the relationship between economic disadvantage and family as well as emotional quality of life in early adolescence in the Chinese culture. This work was financially supported by the Research Grants Council of the Government of the Hong Kong Special Administrative Region, Hong Kong (Grant CUHK4293/03H) and Wofoo Foundation. The author wishes to thank Britta Lee and Joyce Chow for their assistance in collecting the data.
