EFFECTS OF A CHILD'S DISABILITY ON AFFECTED FEMALE'S LABOUR SUPPLY IN AUSTRALIA

Australia has experienced a growing rate of child disability, with the rate of 3.7 per cent in 1998 increasing to 4.3 per cent in 2003 for children aged under four years and from 9.5 per cent to 10 per cent for children aged five to 14 years in the same period. However, surprisingly no study has examined the economic effects of child disability in the Australian context. This paper attempts to quantify the link between a child's disability and the work behaviour of the female in the affected family. Our findings provide empirical justifications for the current policy linking the severity level of child disability to the assessment of eligibility for Carer Payment (Child). We also found that child disability has different impacts on the labour market activities of married women and non‐married women. It appears that child disability imposes a greater hardship on non‐married women than on married women in terms of work choice decision. Once non‐married women manage to enter the labour force, they may have to stay on to work as usual even if they have a disabled child, because they may not have other family members to turn to for help as married women do.

机构投资者是股票市场影响实体经济的助推器吗？——基于投资者情绪对公司资本投资的视角

"资本市场并非有效",股票市场上投资者情绪对公司的实体投资行为具有重大影响。被监管层寄予厚望的机构投资者从中扮演了什么角色?上述重大影响的助推器抑或制衡器,深层的作用机理又是什么?运用行为公司金融理论,研究发现,公司资本投资决策倾向于遵循机构投资者的"专家意见",机构投资者是投资者情绪影响公司资本投资的"助推器","管理者信心"是上述助推功能得以发挥的重要渠道。上述研究发现有助于从微观企业的视角,有效识别机构投资者在股票市场影响实体经济中的角色,为监管层在"后金融危机时代"制定和执行有关机构投资者的政策提供依据;也有益于公司管理层科学理解机构投资者传递的信息,合理规避决策过程中的"专家陷阱"。     

中小企业研发困境的博弈分析

知识经济时代，企业自主研发是增强其竞争力的必经途径。而在国内，众多中小企业对研发投入持消极态度，尽管政府多方鼓励，但收效不大，且企业在自主研发的投入方面与发达国家有着较大的差距。可从严格保护研发成果、协作研发与加大政府的政策优惠力度等方面对中国中小企业的研发投入情况进行改进。     

物业企业服务质量评价研究

物业服务企业要想获得生存与发展,提高服务质量是其必然选择。因此,服务质量评价不但是业主和物业主管部门的要求,而且更符合物业企业自身发展的需要,但当前物业服务质量评价方法比较简单,理论性和系统性等方面都存在不足。物业企业可结合SERVQUAL模型,构建以业主、物业公司及第三方评价为一体的服务质量的评价模型,从而能比较全面地了解自身的服务质量。     

Government Expenditure Financing in a Two‐Sector Cash‐In‐Advance Model of Endogenous Growth

We show that an expansion in the government size could be desirable from the viewpoint of the economy's long‐run growth, wherein factor intensity between the sectors, the mode of public spending financing, and the form of the cash‐in‐advance (CIA) constraint are crucial. We also show that when real balances are required only for consumption purchases, money financing is equivalent to consumption tax financing, but is not equivalent to income tax financing. If both consumption and gross investment are liquidity‐constrained, then the three financing methods are mutually not equivalent. The optimal financing scheme has the following features: (1) when the CIA constraint applies only to consumption purchases, any combination of the money growth rate and the consumption tax rate that satisfies the government budget constraint constitutes an optimal financing mix; (2) when the CIA constraint applies to both consumption and investment purchases, consumption tax financing only is optimal.

国内外电力建设工程竣工移交条件差异及合同纠纷分析

国内外电力建设工程竣工移交时,在性能试验责任主体、时间、试验项目等多方面存在较多差异,进而导致了工程投入商业运行、颁发移交生产交接书、缺陷责任期起始和结束等诸多时间的不一致,这些差异和不一致可能引起业主与EPC承包商之间的合同纠纷。本文对上述差异和可能引起的纠纷进行了分析,并提出对策和建议。     

英语读写素质研究中的二元理论分析

英语读写素质是习得读写能力并形成读写体验的过程。读写素质主要由分析能力、结合社会文化能力、话语分类能力、读写实践能力、记忆能力、情感反应、思辨能力和隐喻理解能力等因素构成。本文首先应用二元理论中的集对分析理论分析了句子、语法和词语,英语句子具有同异性,英语语法中时态的相关性均有特定的语法表征手段,英语词语是一种约定俗成的语言单位常常附衍了一串同义词、近义词和反义词。如果用联系数来描述词语的相关度,它同时也反映出了词语的思想丰度。本文还运用博弈理论和悖论分析文章的含义及价值,最后应用模糊二元对比排序法对英语读写素质各因素进行分析,通过分析确定了各因素的重要度,将其应用于读写素质研究中具有积极作用并具一定的发展潜力。
