随着经济全球化及人们投资观念的转变，越来越多的上市公司已意识到要保证融资渠道的畅通和公司的持续发展，就必须重视投资关系管理。从证券市场规范发展和国际化着眼，我国上市公司投资关系管理规范化已时不我待，并成为我国证券管理层和理论工作必须研究解决的一个现实问题。     

我国保险公司税收制度的完善

我国保险公司税制存在诸多弊端 ,如 :中外资保险公司所得税待遇不同 ,营业税负担过重等 ,阻碍了保险业的发展。笔者建议在考虑政策目标 ,税收原则 ,最终纳税人等相关因素的前提下 ,改革现行保险公司税制。如 :统一中外资保险公司所得税税率 ,降低营业税率并实行差别税率等。     

培育和发展具有核心竞争力的大公司和大企业集团

为了增强中国经济实力和对“入世”后面对的激烈竞争，必须发展大公司和大企业集团。从目前情况看，中国的大公司和大企业集团的核心竞争力还很弱，在技术创新能力，多样化经营能力，适应市场能力和赢利能力等方面都与发达国家的大企业存在很大差距，我们必须从体制，机制，技术创新，增加人力资本，改善外部环境等方面多做工作，促进大公司和大企业集团核心竞争力的提高。

Valuing and Pricing Retail Leases with Renewal and Overage Options

We consider retail leases with landlord overages options, with tenant renewal options, with both and with neither. We illustrate how the ratio of initial expected sales to the sales threshold can be manipulated to equate the value of the landlord overage options to that of the tenant renewal option at the same initial rent. Not only are the values equal, but the cumulative distributions of potential IRRs on the two leases are nearly identical, suggesting that these leases are equally attractive to risk-averse investors and thus that the same risky discount rate can be used in valuing the leases. In contrast, the appropriate risky discount rate for the overage lease is calculated to be 75–160 basis points greater than that for the renewal lease.     

A Semiparametric Method for Valuing Residential Locations: Application to Automated Valuation

This paper is motivated by automated valuation systems, which would benefit from an ability to estimate spatial variation in location value. It develops theory for the local regression model (LRM), a semiparametric approach to estimating a location value surface. There are two parts to the LRM: (1) an ordinary least square (OLS) model to hold constant for interior square footage, land area, bathrooms, and other structural characteristics; and (2) a non-parametric smoother (local polynomial regression, LPR) which calculates location value as a function of latitude and longitude. Several methods are used to consistently estimate both parts of the model. The LRM was fit to geocoded hedonic sales data for six towns in the suburbs of Boston, MA. The estimates yield substantial, significant and plausible spatial patterns in location values. Using the LRM as an exploratory tool, local peaks and valleys in location value identified by the model are close to points identified by the tax assessor, and they are shown to add to the explanatory power of an OLS model. Out-of-sample MSE shows that the LRM with a first-degree polynomial (local linear smoothing) is somewhat better than polynomials of degree zero or degree two. Future applications might use degree zero (the well-known NW estimator) because this is available in popular commercial software. The optimized LRM reduces MSE from the OLS model by between 5 percent and 11 percent while adding information on statistically significant variations in location value.     

Disclosure of Private Information and Reduction of Uncertainty: Environmental Liabilities in the Chemical Industry

We investigate the potential uncertainty-reducing role of accounting information in the context of contingent Superfund liability valuation. We first develop theoretical arguments for the way reduction of uncertainty regarding these contingent liabilities is expected to affect security prices. Empirical proxies are developed for two types of uncertainty surrounding contingent Superfund liabilities: site uncertainty and allocation uncertainty. In a valuation framework, we then investigate whether financial statement disclosures and accruals reduce uncertainty and thereby affect security valuation. Specifically, we analyze the interaction of private information contained in firm disclosures and accruals with inherent uncertainty surrounding contingent Superfund liabilities. Results suggest that in a regulatory environment allowing substantial reporting discretion, firm-provided financial statement information affects valuation of contingent Superfund liabilities by reducing uncertainty. Further, we find that information revealed through accruals versus disclosures is differentially effective at reducing site and allocation uncertainty.     

我国上市公司管理层收购财务绩效的实证研究

管理层收购(MBO)是优化公司治理结构、降低代理成本、充分发挥企业家才能,从而提高公司财务绩效的有效途径。本文以我国深、沪两市中具有代表性的24家上市公司为样本,采用合成数据(Panel Date)截面回归的计量模型,对我国上市公司MBO的财务绩效问题进行了实证研究,结果表明:(1)在比较低的管理层持股比例下,MBO并未提高我国上市公司的财务绩效,且管理层持股比例与公司财务绩效成反向关系;(2)管理层收购前后,公司每股净资产均呈向上的凸性;每股收益随着管理层持股比例的扩大而呈递减趋势。     

上市公司利用减值准备进行盈余管理的实证研究--以吉林省上市公司为例

上市公司于2001年1月1日起开始执行新的企业会计制度,新的会计制度与原会计制度相比最显著的变化就是在原来四项资产减值准备计提的基础上又增加四项减值准备。这八项减值准备的计提,充分体现了谨慎性原则对历史成本原则的修正,目的是为了挤出上市公司资产中的水分,保护所有者和债权人的利益,从而化解其投资风险。通过对吉林省上市公司八项资产减值准备计提情况的分析,可以反映出吉林省上市公司利用减值准备进行盈余管理的实际情况。     

我国商业银行业公司治理结构与经营绩效的实证研究

通过对8家股份制商业银行的公司治理结构与经营绩效的关系做回归分析,结果显示:经营绩效与董事会规模正相关;与第一大股东持股比例负相关;与前5大股东控制权分散度正相关。因此,国有商业银行应当适度增大董事会规模、明晰产权关系、强化监事会职能、加强管理层激励与信息透明度。
