现有“利润加储量”的评估方法应用于资源类公司仍在某些环节出现悖论。本文认为,资源类上市公司的价值构成应包括矿权重估溢价、正常开采投资收益及个别公司的超额利润。其中,采矿权重估溢价的潜在收益应是在矿权未市场化之前的资源类企业获得的特有收益,但其收益期和相应的折现期也因矿权的逐步市场化而受到采矿权有效期的限制。本文用简单模型估算了主要资源类上市公司的基本价值。  相似文献

Properties can be bought by government agencies, land trusts, or private entities for conservation and preservation purposes, such as farmland preservation, wildlife refuges, other conservation, and cultural and historical preservation. There is variation in the dollars paid per acre across properties and across buyer type. An option value model based on future potential land uses is used to explain much of this variation. The data used in our analysis is sales transactions data for conservation and preservation purposes from throughout the United States. We find that much of the value of conservation properties is derived from future potential land uses, including housing, timber, recreation, and conservation. We confirm that public versus private buyers value options differently, which makes sense from a public good point of view, if markets are thin.  相似文献

A number of recent studies have shown that earnings information is less useful and value relevant when firms are financially troubled. This finding has given rise to the consideration of alternatives. In this paper, we examine the contributions of book value-based proxies (normal earnings and abandonment value) and flow-based proxies (earnings and operating accruals) to the assessment of the likelihood of emergence from financial distress. Our prior reasoning is that while book value-based proxies may provide information about potential future cash resources, flow-based proxies, because they capture the progress of reorganization efforts underway, as opposed to mere potential, should be relatively more useful in assessing the likelihood of emergence from distress. Our findings are consistent with this explanation. We document that the primary predictors of emergence are flow-based proxies—in particular, cash from operations, net of earnings.  相似文献

Among the growing literature on value creation in collaborative buyer-seller relationships, most researchers examine relationship value at a single point in time. In the present research, we explore whether different stages of the relationship life cycle moderate the relative importance of value-creating dimensions. To shed light on the dynamic nature of value in B2B relationships, we present the results of a survey among purchasing managers using a quasi-longitudinal research design. Our findings confirm the moderating role of the relationship life cycle in value creation. More precisely, our results indicate that a key supplier's potential for value creation in customer's operations increases in relative importance as relationships move through the life cycle. In turn, supplier's capabilities to create superior value at the level of the customer's sourcing process display a decreasing role over the life cycle of a business relationship. No significant link was found in the present study between value creation through a supplier's core offering and different stages of a buyer-seller relationship.  相似文献

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.  相似文献

公允价值的困境解析及其对策   总被引:20,自引:0,他引:20  
公允价值的运用在国外已成为一种趋势,在我国却并不顺利.文章认为公允价值在理论上是可行的,尽管实际运用中,由于使用者的逐利动机、会计准则制度不完善、相关的法律法规不健全及执法不严等,导致在关联交易、非货币交易、债务重组和资产减值中出现了很多问题,但是通过引入全面收益并且建立良好的实施环境,它也就具有了实务上的可行性.  相似文献

企业经营的价值构成与战略权衡   总被引:5,自引:1,他引:5  
企业为顾客所提供的产品或服务的总价值由顾客价值与企业价值构成。相对于同业中的竞争者或历史上的企业自身,如果企业更能创造顾客价值,则可认为企业有当下经营优势;如果企业更能创造顾客价值与企业价值,则可认为企业有持续经营优势。顾客价值与企业价值是企业经营过程中既对立又统一的两个方面。如何跨期考虑顾客价值与企业价值之间的比例关系,是企业应该而且必须做出的战略权衡。  相似文献

知识员工雇佣管理模式研究--基于SHRM的分析   总被引:1,自引:0,他引:1  
本文从战略人力资源管理的视角,综合运用知识资本理论和战略管理理论熏以知识员工异质性为研究的逻辑起点,根据知识员工所拥有知识的战略价值及企业专用性这两个维度,把知识员工分为先锋型、工兵型、卫士型和盟友型等四种类型,然后较深入地分析了各类知识员工的特点,并在此基础上提出了差异化雇佣管理模式。文章最后还就差异化雇佣管理所带来的问题进行了研究,一方面丰富了雇佣关系管理理论的内容,另一方面也为中国的知识型和高科技企业在实践中分层分类雇佣管理知识员工提供了理论依据。  相似文献

Recent empirical work shows evidence for higher valuation of firms in countries with a better legal environment. We investigate whether differences in the quality of firm‐level corporate governance also help to explain firm performance in a cross‐section of companies within a single jurisdiction. Constructing a broad corporate governance rating (CGR) for German public firms, we document a positive relationship between governance practices and firm valuation. There is also evidence that expected stock returns are negatively correlated with firm‐level corporate governance, if dividend yields are used as proxies for the cost of capital. An investment strategy that bought high‐CGR firms and shorted low‐CGR firms earned abnormal returns of around 12% on an annual basis during the sample period.  相似文献
