从会计等式看产权理论在我国企业的运用

本文认为,会计等式在一定程度上反映了产权理论在企业中的运用状况。传统计划经济体制下的“企业”没有企业的本质属性,其会计等式只记录“企业”使用物质资料和物质资料在“企业”里的分布情况,国家是生产资料的完全所有者,没有产权的存在。现阶段的企业是市场经济的主体,有自己的生产经营权利,追求利润最大化,而组织活动本身又受社会主义市场经济条件下生产资料公有制的影响,其会计等式反映了一定条件下的产权关系,说明了产权理论在会计核算上的运用。文章指出,会计等式中体现的产权思想只是产权经济学的一部分,用会计等式和会计的语言说明生产要素所有者参与利益形成和分配过程的权益,即会计反映的是权力怎样计算为权益的。     

中国钢铁产业国际市场势力实证研究

本文首先运用边际成本模型估算了中国钢铁产业的国际市场势力,发现中国加入世贸组织后钢铁产业的国际市场势力下降,且加入世贸组织前后钢铁产业国际市场势力均较小;然后选取SITC(Rev.2)中两位码为67的钢铁产品,运用剩余需求弹性模型实证研究了其在韩国、印度、日本和美国这些主要出口国市场上的国际市场势力,发现在韩国、日本和印度市场的国际市场势力依次降低,在美国市场的国际市场势力尚未形成,说明中国钢铁产业出口具有一定的国际市场势力,但与此同时,总体上出口单价和进口单价之比有下降趋势,其低成本优势也趋于减弱,中国从钢铁产业贸易中获得的比较利益正不断减少,钢铁产业没有明显的现实国际市场势力。     

Bt Cotton,Pesticide Use and Environmental Efficiency in Pakistan

There is a broad literature on the impact of Bt cotton adoption in different countries, but few studies have explicitly looked at environmental and health effects from an economic perspective. We analyse the impact of Bt cotton on environmental efficiency in Pakistan, using farm survey data and a doubly heteroskedastic stochastic production function framework. Negative environmental and health effects of chemical pesticide use are quantified with the environmental impact quotient. Bt‐adopting farms have higher cotton yields, while using lower pesticide quantities and causing less environmental damage. Bt farms are both technically and environmentally more efficient than non‐Bt farms. Bt adoption increases environmental efficiency by 37%. Achieving the same reduction in negative environmental and health impact without Bt would cost conventional cotton farmers US$ 54 per acre in terms of foregone yields and revenues (7% of total revenues). Extrapolating this shadow price of the technology's health and environmental benefits to the total Bt cotton area in Pakistan results in an aggregate value of US$ 370 million. These benefits are in addition to the profit gains for Bt‐adopting farmers. Our results suggest that Bt technology can contribute to sustainable agricultural development.

所得税申报中资产时间性差异的调整方法比较

在所得税申报中,资产时间性差异的纳税调整要涉及几个纳税年度,并且一个正常生产经营企业的资产往往处在动态过程中。每年有新增资产,也有出售、报废、到期的资产,要准确无误地对其进行纳税调整,是所得税申报中的一个常见问题也是难点问题。文章通过对所得税申报中资产时间性差异调整的两种方法的比较,确定一种较为简便可行的方法。     

Real Options, (Dis)Investment Decision-Making and Accounting Measures of Performance

This paper suggests that a residual income-type measure of performance can be designed which supports optimal investment and disinvestment decision-making in a real options framework involving the options to wait before investing and to abandon. The measure has a number of advantages and disadvantages. Nonetheless, the balance of advantage versus disadvantage for the proposed measure must be set against the inadequacies of other competing measures of performance and associated organisational designs. Even if the measure of performance suggested is not regarded as practically useful, it has another general advantage – it can be used as a benchmark against which to evaluate other performance measures with regard to their support of optimal investment and disinvestment decision-making in a real options framework.     

The effect of takeovers on the fundamental value of acquirers

This paper develops a new methodology to examine the financial impact of acquisitions, designed to address whether takeovers yield a positive net present value for the acquiring company. Specifically, we employ the residual income valuation method to compare the fundamental value of the acquiring company before acquisition with the fundamental value after acquisition.We apply this methodology to 303 UK acquisitions completed during 1985–1996, and compare the results with the effects of takeover on profitability and short‐ and long‐run share returns. We find that the impact of acquisition on fundamental value is slightly negative but statistically insignificant. This result differs from the effect of takeover on profitability, which is significantly positive, and the effect of takeover on share returns, which is significantly negative.
