商业银行网点布局实证研究——以衡水市为例

网点作为商业银行为客户提供金融服务的主要渠道,其布局合理性不仅关系到商业银行经营业绩和竞争力,也关系到社会服务功能的完善。目前,商业银行网点布局随意性和随机性较强,科学的规划和决策不足,资源的浪费和资源配置效率的低下现象突出。实证分析衡水市商业银行网点布局的各种因素,利用数理模型对商业银行网点选址进行分析和优化,以此提高网点布局的科学性与合理性。     

基于链网结合的地方产业集群升级机理与路径

在经济全球化的背景之下,产业集群升级是内因与外因共同作用的结果,单纯考虑其一则有失偏颇。通过建立理论模型,分析了基于链网结合的产业集群升级机理与路径。产业内垂直分工形成了全球价值链,产业集群作为其中的一个环节,其升级必然会受到集群网络与价值链的双重影响,就升级机理而言,产业集群升级要重点关注的是链网结合度问题。对于升级路径来说,产业集群升级可以分为隐性与显性两种升级模式,其中前者是后者的基础;隐性升级的实现是链网结合作用的结果,而显性升级的实现是价值链攀升的结果。我国的地方产业集群的升级,应以链网结合为基础,积极实现隐性升级,提升集群自身竞争力,在此基础上通过价值链的攀升实现显性升级。     

To buy or not to buy? The value of contradictory analyst signals

We study the predictive ability of individual analyst target price changes for post-event abnormal stock returns within each recommendation category. Although prior studies generally demonstrate the investment value of target prices, we find that target price changes do not cause abnormal returns within each recommendation level. Instead, contradictory analyst signals (e.g., strong buy reiterations with large target price decreases) neutralize each other, whereas confirmatory signals reinforce each other. Further, our analysis reveals that large target price downgrades can be explained by preceding stock price decreases. However, upgrades are not preceded by stock price increases, thereby demonstrating asymmetric analyst behavior when adjusting target prices to stock prices. Our results suggest that investors should treat recommendations with caution when they are issued with large contradictory target price changes. Thus, instead of blindly following a recommendation, investors might put more weight on the change in the corresponding target price and consider transaction costs.     

The relationship between banking market competition and risk-taking: Do size and capitalization matter?

This paper addresses the effects of bank competition on the risk-taking behaviors of banks in 10 Latin American countries between 2003 and 2008. We conduct our empirical approach in two steps. First, we estimate the Boone indicator, which is a measure of competition. We then regress this measure and other explanatory variables on the banking “stability inefficiency” derived simultaneously from the estimation of a stability stochastic frontier. Unlike previous findings, this paper concludes that competition affects risk-taking behavior in a non-linear way as both high and low competition levels enhance financial stability, while we find the opposite effect for average competition. In addition, bank size and capitalization are essential factors in explaining this relationship. On the one hand, the larger a bank is, the more it benefits from competition. On the other hand, a greater capital ratio is advantageous for banks that operate in collusive markets, while capitalization only enhances the stability of larger banks under high and average competition. These results are of extreme importance when considering bank regulations, especially in light of the recent turmoil in the global financial markets.

我国社会管理创新的重点与方向

开展社会管理创新必须关注基层问题.基层问题不仅仅具有经济意义,还有重要的社会意义.目前我国基层问题的实质是:私人部门和公共部门缺乏平衡,造就健全社会生活的基层组织有待于进一步健全,基层问题没有被当作核心问题来抓.解决这些问题的方案很多,主要应当考虑:鼓励资源往基层配置,建立新的治理模式,寻求解决基层问题的更开阔思路.     

基于VAR模型对投资、就业与经济增长的实证研究

本文选用中国1978～2007年30年的数据,基于VAR模型运用Granger因果关系检验、脉冲响应分析、方差分解等方法分析投资、就业与经济增长三者之间的关系。实证结果表明:经济增长既是就业的格兰杰原因,也是投资的格兰杰原因;投资是就业的格兰杰原因;就业和经济增长均不是投资的格兰杰原因。投资可以促进就业和经济增长,经济增长也可以促进就业。     

提高劳动报酬在初次分配中比重的对策分析

劳动报酬在初次分配中的比重过低,是当前我国贫富差距过大的直接原因。要提高劳动报酬在初次分配中的比重,必须深化分配制度改革,形成合理的分配结构,建立劳动工资正常增长机制。     

EBCT measured coronary artery calcium scores in asymptomatic life insurance applicants

EBCT measured coronary calcium is fast becoming a standard screening tool in asymptomatic patients with and without risk factors who apply for life insurance. Since atherosclerotic plaques become calcified as part of their natural history, the calcium score is an excellent measure of total atherosclerotic burden. Over the past 5 years, various clinical studies have confirmed the predictive value of the coronary calcium score for both soft (revascularization, MI) and hard (MI and sudden cardiac death) events incrementally and independently of traditional coronary risk factors identified by the Framingham Heart Study. Accurate assessment of cardiac mortality risk in asymptomatic applicants for life insurance should include both traditional risk factor assessments in combination with age and gender specific percentiles for coronary calcium. New data from both new and ongoing clinical trials will seek to further support the predictive value of coronary calcium scores as an independent and incremental predictor of hard cardiac events.
