Estimation of expected return is required for many financial decisions. For example, an estimate for cost of capital is required for capital budgeting and cost of equity estimates are needed for performance evaluation based on measures such as EVA. Estimates for expected return are often based on the Capital Asset Pricing Model (CAPM), which states that expected excess return (expected return minus the risk-free rate) is equal to the asset's sensitivity to the world market portfolio (β) times the risk premium on the “world market portfolio” (the market risk premium). Since the world market portfolio, by definition, contains all assets in the world, it is not observable. As a result, an estimate for expected return is commonly obtained by taking an estimate for β based on some index (as a proxy for the world market portfolio) and an estimate for the market risk premium based on a potentially different index and multiplying them together. In this paper, it is shown that this results in a biased estimate for expected return. This is undesirable since biased estimates lead to misallocation of funds and biased performance measures. It is also shown in this paper that the straightforward procedure suggested by Fama and MacBeth [J. Financ. Econ. 1 (1974) 43] results in an unbiased estimate for expected return. Further from the analysis done, it follows that, for an unbiased estimate, it does not matter what proxy is used, as long as it is used correctly an unbiased estimate for expected return results. 相似文献

In January 1992, Kazakhstan initiated a reform programme to move towards market-determined prices. The price liberalization process was characterized by large relative price shifts and an increase in the overall price level towards those observed in market economies. The paper shows how the piecemeal manner in which prices were liberalized resulted in strong relative price variability over a prolonged period of time, against a background of high inflation. Convergence towards international relative and absolute price levels has progressed but is not complete, with prices for energy and services in particular still below market economy levels. 相似文献

This paper presents the development andvalidation of new measurement tools to exploreself-efficacy toward service and toward civicparticipation. We developed and administereda survey to 851 students in an AACSB-accreditedcollege of business at a comprehensive publicuniversity located in the Midwest. Traditionalscale development methodologies plusconfirmatory factor analysis and simultaneousfactor analysis in several populations wereused to analyze both a primary sample and aholdback sample. Results strongly support thevalidity and reliability of the surveyinstrument. Future use for the instrumentincludes verification of the effectiveness ofpedagogies designed to increase self-efficacytoward service and motivation for civicparticipation in business students. 相似文献

社保基金监管的现状、问题与建议 总被引:2,自引:0,他引:2
目前,我国已经初步确立社保基金监管体制,取得了明显的成效.但依然存在着局部地区违规操作、管理体制不顺畅和相关法制、监管建设滞后等问题.从世界范围社会保障基金监管实践看,依托完备法律法规体制实施社保基金监管,确立社保基金监管部门、监管结构,赋予执法权威,社保基金监管向专业化、市场化发展成为社保基金监管的共同点.借鉴国际先进管理经验,我国应提高立法层次、建立完善的法律体制;强化监管力量,适当集中,构建主辅分明、多重监管的社保基金监管结构;推进社会保险基金监管的市场化. 相似文献

While many mutable competencies and immutable personality traits have been shown to have a direct positive relationship with international assignee success, this study examines whether a set of situation‐specific cross‐cultural competencies comprising cultural agility are also related to international assignee success. This study examines whether the combination of three situation‐specific responses to cultural differences (cultural adaptation, cultural minimization and cultural integration) explain any additional variance in supervisor's ratings of international assignee success above and beyond personality and cross‐cultural competencies. To test this hypothesis, supervisor‐rated of assignees’ effectiveness in working with host nationals was regressed on the number of international assignees’ cultural orientations. Controlling for personality and dynamic competencies, the overall model was significant explaining 17 per cent of the total variance. This study provides some preliminary evidence on the importance of expatriates’ possessing the ability to possess concurrent cultural orientations. The HR practices to foster cultural agility are discussed. 相似文献
