协方差结构模型不收敛原因及解决方法

协方差结构模型实际上是一般线性模型的扩展,它主要利用一定的统计手段对复杂的理论模式加以处理,并根据各种拟合指数对模型作出检验与评价,从而达到证实或证伪事先假设的理论模型的目的。笔者在利用协方差结构模型对北京市居民住房消费行为和意愿进行量化研究时发现协方差结构模型存在不收敛问题,文章提出,导致模型不收敛的原因,一是缺失数据处理方法不当,可采用期望最大化算法(EM算法)和马尔科夫链蒙特卡罗法(MCMC算法)处理数据缺失;二是变量间存在多重共线性,可去掉设置不合理的潜变量以避免共线性问题;三是模型过于复杂,收敛条件苛刻,可调整模型使之简单化,并重新设定收敛条件,促使模型收敛。

新古典经济学在解释中国企业成长中的问题分析

本文认为,新古典经济学理论主要以发达国家的经验为基础,研究视角集中于发达国家的市场结构和企业的产生、成长等问题,在解释中国企业成长过程方面存在一些缺陷:一是经济人假设遇到了障碍;二是我国市场化程度有限,市场结构相互交叉;三是政府的角色不同,参与市场的程度和对市场的影响程度不同;四是国家经济发展的目标或侧重点不同;五是我国经济迅速发展,市场环境和结构变化、技术发展进程加快。文章提出,我们应当辩证地学习和借鉴新古典经济学理论,指导我国经济发展和企业成长。

Underpricing, Subsequent Equity Offerings, and the Long-Run Performance of Japanese IPOs

Using data on IPOs that are issued in Japan during January 1975–March 1989, we examine the deliberate underpricing and overreaction hypotheses to explain high initial returns at offering dates. Specifically, we analyze the cross-sectional pattern of the short- and long-run performance of IPOs. The obtained results indicate that the deliberate underpricing theories which we examine are unable to explain the high initial returns on the Japanese IPOs. Furthermore, for the average of the IPOs, the empirical results are not consistent with the overreaction hypothesis. However, there is evidence consistent with the hypothesis that for a certain minority group of IPOs, the high initial returns occur due to overreactions by investors. We interpret the overall results as indicating that the high initial returns on the Japanese IPOs can be attributed to a mixture of both underpricing and investor overreaction. We conjecture that the binding regulations in Japan led to underpricing. This revised version was published online in August 2006 with corrections to the Cover Date.     

Housing markets and the economy: the assessment

Housing markets have multiple interactions with the rest ofthe economy and these are surveyed in this paper. The driversof house prices include income, the housing stock, demography,credit availability, interest rates, and lagged appreciation,the latter a potential mechanism for overshooting. There israther less agreement on the determinants of new construction,though planning constraints are widely seen as a major issueand one of the causes of the UK housing affordability problem.The paper argues that housing collateral and downpayment constraintsare the key to understanding the role of house-price variationsin explaining medium-term consumption fluctuations. Institutionalvariations between countries and over time account for majordifferences in linkages between house prices and economic activity.This illuminates debates about how monetary and other policyshould react to house-price variations. The paper also discussesthe role of housing markets in explaining regional migrationand location decisions, intergenerational inequality, and restrictingaccess of the less affluent to public goods, such as good schools,which are capitalized in local house prices.

服务承诺策略有效性实施探讨

服务承诺,是服务机构通过公开媒体向顾客预示服务质量或效果,并予以保证或赔付的营销行为,其目的是降低顾客购买风险和增加顾客满意度。但是,服务企业要有效发挥服务承诺的作用,就必须在服务承诺设计上遵守"内容适度"、"表述清晰"和"兑付容易"等原则;在实施服务承诺时,要综合考虑服务本身特点、服务企业状况、服务行业情况和顾客特征等一系列因素。
