石油勘探工程三种期权价值分析

本文参考实物期权二叉树定价模型推导的原理,建立了一套石油勘探工程的二叉树期权价值模型,着重举例分析了石油勘探工程推迟期权价值、增长期权价值、放弃期权价值的应用计算方法。对比了上述三种实物期权价值与传统净现值的差异。分析得出,采用传统净现值和实物期权两种理论的计算结果可能会导致两个截然相反的决策结果。     

约旦社会保障制度改革及其启示

和世界上大多数国家一样,约旦也面临着越来越严重的人口老龄化问题。为此,约旦政府在社会保障领域实施了三项重要的改革措施。一是参数式改革,即不改变现有制度的性质,只是调整具体的参数;二是整合碎片化制度改革,把公务员和军事人员纳入全国统一的社保制度中来;三是未雨绸缪,积极开展公共预筹积累制改革,融资模式由现收现付制逐步过渡到部分积累制,不断完善投资管理体制。这三项改革不仅符合世界银行提倡的改革模式,而且这三项改革措施之间的相互配合与协调,有力地推动了约旦社保制度的改革和发展,具有极强的借鉴意义。     

Analyzing the impact of investment spikes on dynamic productivity growth

Firm-level data usually show that a large portion of firm-level investment takes place in a few investment episodes. This paper assesses productivity growth and its components in production framework that accounts for the dynamics of capital adjustment and relates this to investment spikes using firm-level data of the Spanish meat processing industry over the period 2000–2010. Using the method of impulse responses by local projections, it is shown that investment spikes produce a significant productivity change loss of 0.7% in the first year after the spike. The worsening of technology is the main cause of the reduction of productivity growth in the first year. Technology then improves in the fifth year as a result of investment spike, resulting in the U-shape pattern of relationship. Scale inefficiency significantly improves by 0.4% and 0.5% in the first and second year after the spike has occurred, respectively. All these effects, however, largely depend on the firms׳ size. In particular, it is shown that the loss of technology in the first year mainly pertains to smallest firms, while larger firms experience a negative impact on the contribution of technical inefficiency change to productivity growth.     

Social Return On Investment (SROI): Problems,solutions … and is SROI a good investment?

The conclusion of this special issue on Social Return On Investment (SROI) begins with a summary of both advantages and problems of SROI, many of which were identified in preceding articles. We also offer potential solutions for some of these problems that can be derived from standard evaluation practices and that are becoming expected in SROIs that follow guidances from international SROI networks. A remaining concern about SROI is that we do not yet know if SROI itself adds sufficient benefit to programs to justify its cost. Two frameworks for this proposed metaevaluation of SROI are suggested, the first comparing benefits to costs summatively (the resource → outcome model). The second framework evaluates costs and benefits according to how much they contribute to or are caused by the different activities of SROI. This resource → activity → outcome model could enable outcomes of SROI to be maximized within resource constraints (such as budget and time limits) on SROI. Alternatively, information from this model could help minimize the costs of achieving a specific level of return on investment from conducting SROI. Possible problems with this metaevaluation of SROI are discussed.     

Development and validation of the Perceived Investment Value (PIV) scale

This study aims to develop a complementary and more comprehensive measurement to assess the nature of investment value affecting consumers’ investment behavior. Recent research suggests that consumers may desire and obtain certain outcomes from investments that have not been anticipated in mainstream finance and economics literature. These benefits might be hedonistic or altruistic, self-expressive or emotional and experiential. Yet, while an increasing amount of attention has been paid to this topic, little effort has been made to develop an appropriate measurement scale for the subjective consumer perceptions of investments. To address this gap in the literature, this study introduces the concept of Perceived Investment Value (PIV), and develops and validates a measurement scale for the concept. The ultimate 18-item PIV scale parsimoniously represents six Perceived Investment Value dimensions: Economic value—Monetary savings; Economic value—Efficiency; Functional value—Convenience; Emotional value—Emotions and Experiences; Symbolic value—Altruism; and Symbolic value—Esteem. The final measurement scale demonstrates acceptable reliability and validity. Implications related to the developed scale are discussed in terms of their potential to inform a future research agenda.

投资理论的历史考证与组合投资的基本问题探析

欧盟债务危机的全面爆发,引起了人们对两个传统话题的热议,一是政府债券是否永远都是无风险的“金边债券”;二是广大投资者如何应对越来越复杂的“投资风险”。前者属于广大投资者无能为力的事情,后者才是其需要研究和解决的问题。本文通过对投资理论发展过程的历史考察,目的在于说明组合投资是应对投资风险的有效手段;通过对组合投资特点和效果的理论分析,目的在于引起广大投资者对投资组合问题的关注,以便在投资实践中立于不败之地。     

鼓励企业“走出去”的税收法律机制研究

＂走出去＂战略的实施,对我国税收法律机制提出了新要求。我们应尽快制定包括ODI税收条款在内的海外投资基本法;明确ODI税收激励的产业和区域政策导向;完善消除国际重复征税的法律规定;强化税收激励机制;扩大税收协定网络;规范对＂走出去＂企业的税收管理和服务。     

企业实施食品可追溯体系的投资意愿与投入水平研究

基于Logistic、Interval Censored回归模型,研究了影响食品生产企业实施可追溯体系的投资意愿与投资水平的主要因素。结果表明,79.2%的企业愿意投资实施可追溯体系,其中80.7%的企业选择的投资水平在新增投资的20%及以下。影响企业实施可追溯体系投资意愿的主要因素是企业从业人数（1000-2000人之间）、管理者年龄、预期收益和政府优惠政策,而影响投资水平的主要因素是农副产品加工业的行业特征、销售规模（3亿元及以上）、管理者学历层次（大专及以上）和预期收益。     

Investment, resolution of risk, and the role of affect

This experimental study is concerned with the impact of the timing of the resolution of risk on investment behavior, with a special focus on the role of affect. In a between-subjects design, we observe the impact of a substantial delay of risk resolution (2 days) on investment choices. Besides the resolution timing all other factors, including the timing of payout, are held constant across treatments. In addition, state-of-the-art experimental techniques from experimental economics and psychology are used for eliciting preferences and to explicitly measure emotions and personality traits. Participants put their own money at stake. Our main finding is that the timing of the resolution of risk matters for investment, modulated by the probability of investment success. Emotions are found to play a significant role in this respect and explain our main finding. Our results support recent models of decision making under risk trying to incorporate anticipatory emotions but also uncover some important shortcomings related to the dynamics of emotions.
