我国土地征用制度探讨

国家为了公共利益的需要,可以依法对土地实行征用,但是这种征用必须符合公共利益、给予公平补偿、满足正当程序的要求。完善我国土地征用制度应该在这三个方面着手。     

Conditional and Unconditional Conservatism:Concepts and Modeling

We develop a model that captures the distinct natures of and interactions between conditional and unconditional conservatism. Under unconditional conservatism, the book value of net assets is understated due to predetermined aspects of the accounting process. Under conditional conservatism, book value is written down under sufficiently adverse circumstances, but not up under favorable circumstances. The specification of earnings provided by the model yields hypotheses about how unconditional conservatism and other factors preempt conditional conservatism and so affect the asymmetric response of earnings to positive and negative share returns, both current and lagged, documented by Basu (1995, “Conservatism and the Asymmetric Timeliness of Earnings.” Ph.D. dissertation, University of Rochester’ 1997, “The Conservatism Principle and the Asymmetric Timeliness of Earnings.” Journal of Accounting and Economics 24, 3–37).This revised version was published online in August 2005 with a corrected cover date.     

Risk-taking incentives of executive stock options and the asset substitution problem

Various theoretical models show that managerial compensation schemes can reduce the distortionary effects of financial leverage. There is mixed evidence as to whether highly levered firms offer less stock‐based compensation, a common prediction of such models. Both the theoretical and empirical research, however, have overlooked the leverage provided by executive stock options. In principle, adjusting the exercise prices of executive stock options can mitigate the risk incentive effects of financial leverage. We show that the near‐universal practice of setting option exercise prices near the prevailing stock price at the date of grant effectively undoes most of the effects of financial leverage. In a large cross‐sectional sample of Canadian option‐granting firms, we find evidence that executives' incentives to take equity risk are negatively rather than positively related to the leverage of their employers.     

金融自由化利益的纷争和实证分析

自麦金农和爱德华肖在1973年提出金融深化理论后的30年中，西方许多经济学家对金融自由化的利益倍加关注，并进行了激烈的论战。这些争论带给我们很多有益的启示：金融自由化是一种手段，而不是目的本身；自由化是相对的，过度开放和过度压抑同样都是有害的；金融自由化的后果可以是双重的，有些作用是相互抵消的；金融自由化与危机有关，但后并非前的必然结果。以金融全球化带来的负面影响否认金融全球化的效率和结果是一种偏见。     

项目总控的应用及其信息处理规划

随着国内大型建设项目的增多，大型建设项目的实施遇到诸多问题，其原因主要是业主对项目的控制能力不强，从而导致大型建设项目不能实现其质量、进度、投资等预期目标，甚至会导致整个项目的失败，项目总控模式的应用很大程度地解决了这一问题，另外，由于信息处理是项目总控的主要工作，因此，本也讨论了项目总控模式下的信息处理规划。     

The Impact of Acquisitions on Operating Performance: Some Australian Evidence

This study investigates the impact of acquisitions on the operating performance of Australian firms. For a sample of 36 Australian acquisitions occurring between 1986 to 1991 inclusive, and using matched firms to control for industry and economy-wide factors, the results based on four accrual and four cash flow performance measures show that corporate acquisitions do not lead to significant improvements in post-acquisition operating performance. The consistency of the results with the agency, the hubris and the financial motivation hypotheses suggests that corporate acquisitions in Australia may be undertaken for other than synergistic reasons. The results assist in explaining inconsistent findings reported in the literature.     

培育和发展金融资本促进我国金融业改革

作为世界贸易组织成员国，在经济全球化、全球金融市场一体化和金融自由化的大环境中培育和发展金融资本，是我国金融业的发展趋势，也是更为适合的改革途径。本文试图从金融资本理论出发，探讨这一改革途径的必要性、可能性和发展思路。     

完善我国社会保障财政制度的法律思考

财政作为社会保障的核心组织者和保障资金的重要提供者，在社会保障中起有着十分重要而独特的作用。本文分析了建立和完善我国社会保障财政制度的必要性，并从社会保障预算、社会保障税、社会保障财政转移支付三个方面对我国社会保障财政制度的法律完善进行了探讨。     

中国金融垄断的一个例证--实际利差扩大化

随着股份制商业银行的壮大和中小金融机构的兴起以及外资银行的进入，我国国有商业银行一统天下的局面有了很大改观，但是国有商业银行的垄断地位却没有发生根本性改变。国有商业银行依然凭借其垄断地位，直接或间接地获取垄断利润。本从国有商业银行存贷款利差分析入手，阐述了实际利差扩大化的产生机理，指出国有商业银行垄断地位是实际利差扩大化的制度基础，从而表明实际利差扩大化正是我国金融垄断的一个有力证据。     

The macroeconomic determinants of technology stock price volatility

Stock prices reflect the value of anticipated future profits of companies. Since business cycle conditions impact the future profitability of firms, expectations about the business cycle will affect the current value of firms. This paper uses daily and monthly data from July 1986 to December 2000 to investigate the macroeconomic determinants of US technology stock price conditional volatility. Technology share prices are measured using the Pacific Stock Exchange Technology 100 Index. One of the novel features of this paper is to incorporate a link between technology stock price movements and oil price movements. The empirical results indicate that the conditional volatilities of oil prices, the term premium, and the consumer price index each have a significant impact on the conditional volatility of technology stock prices. Conditional volatilities calculated using daily stock return data display more persistence than conditional volatilities calculated using monthly data. These results further our understanding of the interaction between oil prices and technology share prices and should be of use to investors, hedgers, managers, and policymakers.
