Limiting Auditors' Liability: The Potential Consequences

The recent revival of interest in the issue of limiting auditors' liability raises questions about the potential effect of such a limitation on auditors' performance. This paper considers the consequences of limited liability from the perspectives of contracting theory and economic arguments. We examine the potential effect of a reduction in auditors' liability on the standard of care or quality of service they provide, emphasising the "calculus of negligence" concept used by Australian courts. We consider the potential impact of reduced liability on the auditor's decision to shirk responsibilities (the moral hazard problem) and on the value placed on audit services. The analysis shows that placing a statutory cap on auditors' liability has the potential to reduce the effectiveness of bonding mechanisms; provide an avenue for divergent behaviour; lower the level of care provided by auditors; and decrease the value of audit services.     

具缺货期不同决策支配权的两级供应链合作机制研究

从考虑市场需求固定且卖方和买方对缺货期的不同决策支配权情况,研究了两级供应链的合作机制,建立了其不完全信息的动态博弈模型,并得出其精炼贝叶斯纳什均衡,从理论上证明了卖方和买方分别占支配地位和从属地位时买方卖方应相互合作。     

Immigration and Economic Welfare: Resource and Environmental Aspects*

The relation between immigration and the economic welfare of residents b analyzed for resource-rich economies (such as Australia) both under competitive conditions and when various distortions are present Immigration provides efficiency gains for residents under distortion–free competition for standard ‘gains from trade’ reasons. Such reasons, however, tend to be ignored by immigration and ‘optimal population’ theorists who raise the issue of restricting immigration without explicitly referring to the distortions. In situations where distortions and externalities are present, we argue that it is generally preferable to devise policies which specifically target the distortions than to restrict immigration.     

基于CVM的征地补偿价格测算——以湖北省荆门市为例

采用意愿调查法等方法,通过调查农户受偿意愿和市民支付意愿,测算出荆门市基于农户最低受偿意愿的征地补偿价格为85.77万元/公顷,基于市民最高支付意愿的征地补偿价格为147.03万元/公顷.并通过构建回归模型,探讨影响农户受偿意愿和市民支付意愿决策的显著因子;为合理确定征地补偿标准提供依据.     

金融发展与城乡居民收入差距关系探讨--以中国西部12省区为例

文章基于2002-2011年中国西部12个省份金融市场（金融中介和保险市场）发展状况面板数据,建立回归模型,利用pooled LS回归和基于贝叶斯线性回归理论的MCMC算法,对西部地区金融发展与城乡居民收入差距之间的关系进行实证分析。研究结果表明：金融中介发展拉大了西部地区城乡居民收入差距,而保险市场发展则对西部地区城乡居民收入差距的扩大有抑制作用。并在文章的最后对出现这些情况的原因以及政策建议进行了阐述。     

人口老龄化背景下提升我国城镇职工养老保险统筹层次分析及建议

我国自2000年起进入人口老龄化社会,近年来人口老龄化趋势持续上升,提升基本养老保险制度的保障能力成为急需,其中,提高基本养老保险的统筹层次为完善养老制度的步骤之一.2011年,中共中央在"十二五"规划中做出明确指示,由社会统筹账户中的基础养老金部分率先实行全国统筹,但在具体实施过程中却有一定困难.实现城镇职工养老保险的全国统筹需要突破当前存在的瓶颈问题,采取切实可行的举措.     

中国体育产业区域竞争力综合评价--基于31个省区的比较研究

文章在已有研究的基础上,从产业发展水平、经济发展水平、市场基础条件等三个层面构建了中国体育产业区域竞争力综合评价指标体系,并采用因子分析法对中国31个省（自治区、直辖市）的体育产业竞争力进行综合评价分析。结果表明,中国体育产业区域竞争力存在着明显差异：东部地区的京沪广等省市处于第一梯队,中部地区位于第二梯队,西北省区除陕西处于第二梯队外,其余则大多位于第三梯队。可见中国体育产业的区域竞争力与经济发展程度是基本一致的。对于西部地区体育产业竞争力的提升,主要应该通过构建产业园区,推动特色体育产业集群发展,创新全民体育运动项目等方式来实现。     

Stock Price Dynamics and Firm Size: An Empirical investigation

We show that after controlling for the effects of bid-ask spreads and trading volume the conditional future volatility of equity returns is negatively related to the level of stock price. This “leverage effect” is stronger for small, as compared to large, firms. We also document that while the essential characteristics of the relations between stock price dynamics and firm size are stable, the strengths of the relationships appear to change over time.
