论可持续发展与科技税收政策

我国要实施可持续发展战略,必须制定一整套符合可持续发展要求的税收政策--可持续发展税收.科技税收政策是可持续发展税收政策的重要内容.文章分析了我国现行的鼓励科技发展的税收措施,通过比较与借鉴国外促进可持续发展的科技措施,提出了有关建立和完善我国科技税收政策的建议.     

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.     

独立审计质量影响因素分析

独立审计服务质量的高低影响到其对投资者保护的有效程度,进而影响到社会公众投资者的信心和一国资本市场发展的成熟程度。如何有效地提高独立审计质量,历来成为政府监管部门、立法机关、公众投资者等利益相关者关注的焦点。提高独立审计质量的一个前提是,需要明确影响独立审计质量的主要因素有哪些。对此,国内外许多学者对此进行过研究,这些研究或者是规范角度的一般理论分析,或者是从实证检验角度进行。本文则从较少受到关注的审计师专业胜任能力、审计师工作强度以及审计收费三个角度,进行实际调查分析,考察这三个因素对独立审计质量的影…     

Explosion in the quasi-Gaussian HJM model

We study the explosion of the solutions of the SDE in the quasi-Gaussian HJM model with a CEV-type volatility. The quasi-Gaussian HJM models are a popular approach for modeling the dynamics of the yield curve. This is due to their low-dimensional Markovian representation which simplifies their numerical implementation and simulation. We show rigorously that the short rate in these models explodes in finite time with positive probability, under certain assumptions for the model parameters, and that the explosion occurs in finite time with probability one under some stronger assumptions. We discuss the implications of these results for the pricing of the zero coupon bonds and Eurodollar futures under this model.

Measuring the Level and Inequality of Wealth: An Application to China

We construct and compare three distinct measures of household asset wealth that complement traditional income‐ or expenditure‐based measures of socioeconomic status. We apply these measures to longitudinal household survey data from China and demonstrate that household asset wealth has been increasing over time, a theme consistent with many previous studies on the process of development in China. Unlike other studies that have shown rising income inequality over time, however, we show that asset wealth inequality has actually been declining in recent years, indicating widespread participation in the benefits of economic reforms. Furthermore, the evolution in the cumulative distribution of household welfare is such that social welfare has been increasing with the passage of time, despite rising inequality in the early years of the survey.     

The Joint Effects of Multiple Legal System Characteristics on Auditing Standards and Auditor Behavior

This paper derives the impacts of legal system characteristics and auditing standards on auditor behavior (audit quality), and analyzes the determination of optimal auditing standards under different legal regimes. Legal regimes are characterized by differences in the uncertainty concerning the outcome of legal proceedings (termed vagueness of legal systems) and differences in the average size of damage awards. Auditing standards as determined by standard setters can vary in both toughness and vagueness. Our analysis provides implications for the adoption of International Standards on Auditing (ISA). Countries, such as the United States, where auditor legal liability is significantly more onerous than the global norm are not likely to adopt ISA, since these standards may not induce auditors to provide the optimal level of audit quality. Conversely, the adoption of ISA by countries, such as China, where the legal system makes the recovery of damages from auditors quite difficult, is not by itself likely to result in a high level of audit quality. Furthermore, our model suggests that auditor rotation can help improve audit quality, but only in certain circumstances.
