A comparison of several approximations to the power function of the likelihood ratio test in covariance structure analysis*

In this paper we compare alternative asymptotic approximations to the power of the likelihood ratio test used in covariance structure analysis for testing the fit of a model. Alternative expressions for the noncentrality parameter (ncp) lead to different approximations to the power function. It appears that for alternative covariance matrices close to the null hypothesis, the alternative ncp's lead to similar values, while for alternative covariance matrices far from H_o the different expressions for the ncp can conflict substantively. Monte Carlo evidence shows that the ncp proposed in Satorra and Saris (1985) gives the most accurate power approximations.     

从美国公司财务假帐丑闻看公司治理和社会制约的完善

美国公司财务假帐频繁产生的原因有：公司管理制度和公司治理结构方面的变化对企业的约束力下降在社会中介机构的独立审计制度下部分中介机构与造假公司同流合污，法律制度的缺陷与不完备，以及政府对企业投资银行和征券行业的监管机制不健全等。有鉴于此，我国公司应建立、健全监音管理机制，并加强公司内部控制。     

Commodity currencies

This paper looks at real exchange rate behavior by focusing on three OECD economies (Australia, Canada, and New Zealand) where primary commodities constitute a significant share of their exports. For Australia and New Zealand especially, we find that the US dollar price of their commodity exports (generally exogenous to these small economies) has a strong and stable influence on their floating real rates, with the magnitude of the effects consistent with predictions of standard theoretical models. However, after controlling for commodity price shocks, there is still a purchasing power parity puzzle in the residual. The results here are relevant to developing commodity-exporting countries as they liberalize their capital markets and move towards floating exchange rates.

上市公司利润泡沫的剖析

利润是企业经营成果的集中体现,也是衡量企业经营管理业绩的主要指标之一。随着财务报告信息在市场经济中地位的不断提升,部分上市公司为了寻求对自己有利的财务成果,不惜一切手法操纵利润,甚至采用欺诈手段不合法地调整企业的利润,形成了泡沫利润,损害了投资者的利益,影响了我国证券市场的正常发展。本文针对目前上市公司财务报表的利润浮夸现象,就企业泡沫利润的形成原因、手段进行分析,并对如何识别泡沫利润的手段提出了初浅的看法,最后提出了相应的防范措施。     

Linear Programming Models for the Measurement of Environmental Performance of Firms—Concepts and Empirical Results

I use linear programming models to define standardised, aggregate environmental performance indicators for firms. The best practice frontier obtained corresponds to decision making units showing the best environmental behaviour. Results are obtained with data from U.S. fossil fuel-fired electric utilities, starting from four alternative models, among which are three linear programming models that differ in the way they account for undesirable outputs (pollutants) and resources used as inputs. The results indicate important discrepancies in the rankings obtained by the four models. Rather than contradictory, these results are interpreted as giving different, complementary kinds of information, that should all be taken into account by public decision-makers.
