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.     

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.

推动我国税务代理业发展的思考

我国法制建设的不完善、税务代理机构行为的不规范、税制结构的不完善以及执法刚性的不足等因素制约了我国税务代理的发展,为了推动我国税务代理事业的发展,应该采取以下措施:健全税务代理制度,提高法律级次;明确执业范围,强化管理手段,规范税收代理执业行为;完善税制结构,强化依法治税的社会环境;加强对税务代理市场的培育。     

船舶评估重置全价的确定

由于船舶资产专业性强,在评估该类资产时,评估人员因知识面限制,对如何确定船舶重置全价常感到无所适从.尤其对大型船舶,因涉及商业机密,无法进行直接询价,即便询到价格,其准确度也无从把握.本文详细介绍了船舶资产重置全价应包含的内容及确定过程,供评估人员在有关工作中参考.     

Politically connected boards,value or cost: evidence from a natural experiment in China

This study investigates the net effect of a politically connected board for a firm. Using a natural experiment in China – a regulatory change to forbid bureaucrats from sitting on the board of public firms – we address the causality of the net effect of a politically connected board by testing the market reaction of the shares of firm targeted by the regulatory change to the policy announcement. The stocks of firms with politically connected directors who are targeted by the regulatory change show on average a significantly positive abnormal return, which suggests that the agency cost effect of a politically connected director dominates the value effect. The result is robust to various model settings and to a matched sample using the propensity score methodology. Additionally, the announcement effect of the resignation of a politically connected director is significantly positive, and significantly higher than that of a non‐connected director. Overall, our results suggest that the agency cost effect of a politically connected director dominates the value effect.
