再就业小额担保贷款实证研究——以江西为例^①

本文在简要回顾前期研究成果的基础上，结合再就业小额信贷面临的难题，剖析了全国再就业小额担保贷款开展最早、规模最大的“江西模式”的运作机制，其成功之处在于下岗工人、金鬲虫组织、政府的效用水平实现了帕累托改进，并证明金融服务不仅能为高收入者“锦上添花”，而且能为低收入者“雪中送炭”；最后，本文在得出“江西模式”启示的同时，提出了进一步完善和推广再就业小额信贷的建议。

The effect of differential accounting conservatism on the “over-valuation” of high-tech firms relative to low-tech firms

This paper examines systematic differences in the level of accounting conservatism between high-tech and low-tech firms. Relying on the recent development in theoretical models and empirical measures of conservatism, we investigate conservative accounting practices and earnings management behavior in high-tech and low-tech firms. The results based on comparisons of cumulative nonoperating accruals, regression coefficients from the income timeliness models in Basu (1997), the distribution of earnings, and discretionary accruals between the two groups are consistent with a higher level of accounting conservatism in high-tech firms vis-à-vis low-tech firms. Additional analyses show that the effect of conservatism cannot be used as a defense for the over-valuation of high-tech firms.     

中国石油公司海外经营的汇率风险管理初探

汇率风险主要有折算风险、交易风险和经济风险.保值工具是汇率风险管理的有效手段.对于汇率波动较为频繁,但波动幅度不大,从长期看(一年以上)汇率稳定在一定水平的国家,可以不采取任何管理措施和衍生工具.对于汇率波动幅度较大、波动次数频繁的国家,应将管理的重点放在经济风险上,合理使用外币债务、重视内部保值措施.对于汇率变动较为频繁,有时波动幅度较大的国家,应将管理的重点放在短期交易风险上,同时综合考虑风险管理成本和收益,合理使用一些衍生工具进行保值.针对我国石油公司外汇风险管理状况和海外石油项目所在国家汇率变动的特点,提出五点建议:1)外币资金集中管理,尽量实现同种外币流入和流出的匹配;2)从项目经济评价阶段开始就把汇率风险作为一项重要的内容进行管理;3)使用不同的保值工具组合,以达到保值增值的目的;4)利用外币债务进行风险防范;5)加强培训和海外项目汇率风险研究.     

从国开行的统贷模式探讨中小企业融资难题

中国中小企业的组织形式、企业规模等因素,决定了股票和债券市场不可能成为其有效的融资渠道。没有足够的可抵押资产及相应的担保更无法获得银行贷款。国家开发银行开创性的创造出了一个开放性的融资体系。这个融资体系包括一个向中小企业提供贷款的平台和一个为贷款提供担保的平台。这种开放式融资体系中的贷款模式有效的破解了中小企业融资市场中的规模难题、软信息难题及担保难题,为商业银行提供了有效借鉴。     

Insider Ownership and Firm Value: Evidence from Real Estate Investment Trusts

Real estate investment trust (REIT) provides a unique laboratory to study the relation between insider ownership and firm value. One, a REIT has to satisfy special regulations which weaken alternative mechanisms to control agency problems. Empirically, I find a significant and robust nonlinear relation between Tobin's Q and REIT insider ownership that is consistent with the trade-off between the incentive alignment and the entrenchment effect of insider ownership. Two, many REITs are Umbrella Partnership REITs (UPREITs) which have dual ownership structure. They have both common shares and Operating Partnership Units (OP units). Property owners can contribute their properties to the UPREIT in exchange for OP units. Their capital gains taxes remain deferred as long as they hold onto their OP units and the UPREIT does not sell the properties they contributed. OP units owners are locked in with the firm and have incentive to monitor firm management, but their interests diverge from the common shareholders because their tax bases are much lower. Consistent with the trade-off between positive monitoring effect of OP units and tax-induced agency costs, I find that UPREIT's firm value increases with the fraction of OP units, but the effect is significantly weaker for the UPREITs where insiders hold OP units.
