资产评估法律责任的法律法规分析

我国资产评估行业经过十几年的迅速发展，已经成为与注册会计师和律师并列的三大中介服务行业之一，是我国市场经济体系的重要组成部分。然而，近几年证券市场上公开披露的重大违规案例，很多都直接或间接与资产评估有关，尤其“麦科特”公司虚假上市案，资产评估“诉讼爆炸”时代即将来临，资产评估法律责任引起广泛关注。本从资产评估法律责任的相关法律法规的比较入手，找出了其存在的问题，并进行了理论分析。     

Pollution Externalities in a Model of Endogenous Fertility and Growth

An endogenous growth model with human capital formation, pollution caused by production of consumption goods, and endogenous fertility decisions made by altruistic agents with infinite horizons is presented. Consequences for optimal policy of modelling fertility as an explicit decision variable are examined. Because ordinary lump-sum transfers to individuals are no longer neutral, either revenue from a pollution tax must be redistributed to dynasties (working as an implicit tax on child births), or lump-sum transfers must be supplemented with an explicit fertility tax. Alternatively, the government can avoid distortions of the fertility decisions by maintaining an appropriate public debt. When abatement is highly productive, it can be optimal to subsidize fertility in order to increase total production.     

环境分析中沾污与损失的来源及相应对策

将环境污染分析的全过程中沾污的来源归纳为实验室空气、实验用容器、实验设备、实验试剂、实验用溶剂以及工作人员等 6个方面 ;将损失的来源归纳为容器吸附和挥发损失两方面 ,同时给出了减轻沾污与损失的对策     

关于社会保险的深层次思考

正确认识社会保险税并非一般意义上的税，而是介于税费之间，从而跳出了目前的费改税之争，对当前我国社会保障制度的构建具有重要的指导作用。关于社会保险模式的选择，结合我国实际，针对不同群体可选择“并列型和个人主导型”。运用收支两条线和提高社会保障立法层次构建起社会保障运行的制约机制。同时，要在工会的参与实施下，通过制度规则建企，构建社会保险的补充形式，如企业保险、社区互助等。     

Locally Greater Vulnerability to Background Risk

Willingness to take on risk is influenced by the presence of fair and unfair background risks for decision makers who are risk vulnerable as defined by Gollier and Pratt [1996], for these decision makers are more risk averse when they possess such an uninsurable background risk. We present an alternative derivation of the index of local vulnerability based on Diamond and Stiglitz [1974] compensated increases in risk, such that risk aversion increases with the introduction of any small fair background risk if and only if the index of local vulnerability is positive. We establish that the increase in risk aversion is greater for those who are more vulnerable as measured by the index of local vulnerability.     

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.     

建立和完善环境管理体系实现企业可持续发展

针对加入WTO后石油天然气行业所面临的形势，从国际、国内、行业三个方面进行了详细分析，找出了我国石油行业之间的差距以及自身存在的问题。只有巩固与完善石油行业HSE管理体系，建立并实施加14000环境标准管理体系，正确处理好HSE管理体系与ISO 14000环境标准管理体系间的关系，才能最终实现我国环境标准与国际环境标准接轨。同时还要积极推行清洁生产，使企业从传统的由资源到产品再到污染物排放的线型经济模式中解脱出来，实现由资源到产品最终到再生资源的循环经济模式。只有这样，企业才能做到环境与经济的融合，才能提高企业市场竞争力，最终实现可持续发展。     

Capital mobility,wage bargaining,and social insurance policies in an economic union

In a two-country model with mobile capital we analyse decentralized social insurance policies. These policies are a compromise between the preferences of workers and capital owners. Due to wage bargaining, worker-based social insurance contributions are borne by capital owners. These contributions affect the profitability of investment, and consequently the direction and size of capital flows. Countries will take account of these effects in determining social insurance policy. Noncooperative decision making results in tax competition and an underprovision of social insurance. In addition, increasing economic integration, represented by increasing capital mobility, could imply a divergence of social insurance levels in the two countries.     

银行保险的制度变迁理论分析以及对我国的启示

20世纪80年代以来,无论是一直实施混业经营的欧洲,还是近几年重新走上混业经营之路的美国,银行保险都成为一种潮流和趋势。银行保险业务的产生及发展,既源于微观领域经营环境和竞争环境的变化,也源于宏观领域制度管制的放松和信息技术的迅猛发展,更源于银行保险经济学机理带来的范围经济和协同效益。银行保险作为一种制度创新的产物,更多地体现为从销售渠道创新到业务产品创新,再到组织模式创新的金融一体化的制度变迁过程。本文从制度变迁理论的角度对银行保险的产生动因以及演变发展进行分析,以期对我国银行保险的走向提供借鉴。     

Valuing Mortgage Insurance Contracts in Emerging Market Economies

We develop a new option-based method for the valuation of mortgage insurance contracts in closed form in an economy where agents are risk neutral. While the proposed valuation method is general and can be used in any market, it may be particularly useful in emerging market economies where other existing methods may be either inappropriate or are too difficult to implement because of the lack of relevant data. As an application, we price a typical Serbian government-backed mortgage insurance contract.
