实物期权定价模型在我国应用的障碍分析 总被引:3,自引:0,他引:3
实物期权评估方法是20世纪应环境变化的要求发展起来的新的项目评估方法之一。我国的项目评估研究和实践领域也高度关注该方法,以应对今天复杂多变的经济环境。但是,我国目前经济环境特征决定了国外模式在我国不能完全适应,我们在和世界接轨的时候,也必须做出改进。本文结合我国经济环境详细分析了实物期权两种定价模式中各个定价参数在获得过程中所面对的部分障碍,为今后期权评估方法在我国的应用提出部分建议。 相似文献

摘 要:本文将川渝毗邻地区合作共建区域发展功能平台统称为川渝毗邻地区合作示范区(以下简称“示范区”),并以此为研究对象,通过泰尔L指数,测度示范区经济发展差异,随后运用哈肯模型、耦合协调和灰色关联度等方法进行协调度分析。研究发现,各示范区经济发展差异较小,经济发展趋同,加剧示范区之间的竞争,削弱协同合作,抑制比较优势的发挥和提升;成渝“双核”对示范区的辐射带动作用不明显,示范区总体与成渝“双核”的差距仍然较大;在示范区协同发展中,经济金融活动发挥着主导作用,经济环境与金融支持协调发展趋势向好,金融支持对示范区协同发展有显著的正向影响。基于此,建议大力发展新型金融业态,为优势产业发展营造良好的金融支持环境;开辟特色金融“试验区”,引入特色金融活水,有针对性地加强各示范区优势产业和特色产业的金融支持,进一步提升比较优势,强化示范区与成渝“双核”的经济联系,为成渝地区双城经济圈高质量发展提供重要支撑。 相似文献

Internet Protocol Television (IPTV), the convergence services of television and Internet, is being rapidly developed around the world. The advent of digital technologies has changed the convergence market dramatically with the wide diffusion of the convergent services. Using the Technology Acceptance Model as a conceptual framework and method of logistic regression, this research analyzes the demand for IPTV by drawing data from 452 consumers. Individuals' responses to questions about whether they accept IPTV are collected and combined with observations of their socio-economic status and intrinsic/extrinsic factors modified from the Technology Acceptance Model. Results of logistic regression show two variables (intrinsic and extrinsic factors) that seem to explain what influences consumer behavior towards adopting IPTV. Overall, the logistic regression model explains over 50% of the variance in the IPTV adoption. The variances shed light on the multi-open platform environment that IPTV will forge. 相似文献

Summary. This paper extends the work of Ray and Vohra [3]. It ascertains which partitions of players will emerge and what actions
will these players choose under each partition, when they can sign binding agreements and their actions have externalities.
The emphasis, however, is placed on situations with multiple outcomes and how agents behave in the presence of such multiplicity.
In particular, a deviating coalition considers all the likely outcomes that may prevail upon its deviation, and selects (if
possible) a subset of them. Three augmentations of Ray and Vohra's [3] solution concept are defined, capturing three distinct
behavioral assumptions. Efficiency of and the relation between the three notions are discussed.

Abstract. This paper contributes to the growing literature that analyses the Spanish publishing performance in Economics throughout
the 1990s. Several bibliometric indicators are used in order to provide Spanish rankings (of both institutions and individual
authors) based on Econlit journals. Further, lists of the ten most influential authors and articles over that period, in terms of citations, are reported.
We are grateful to many colleagues who made very useful remarks to preliminary versions of this paper, as well as to two anonymous
referees. We are particularly indebted to Xavier Sala-i-Martín, without whose invaluable help this work would not have been
possible. All errors or omissions are of our exclusive responsibility. 相似文献

Tests of unit roots and other nonstationary hypotheses that were proposed by Robinson (1994) are applied in this article
to the Nelson and Plosser's (1982) series. The tests can be expressed in a way allowing for structural breaks under both the
null and the alternative hypotheses. When applying the tests to the same dataset as in Perron (1989), we observe that our
results might be consistent with those in Perron (1989) when testing the nulls of trend-stationarity or a unit-root. However,
we also observe that fractionally integrated hypotheses may be plausible alternatives in the context of structural breaks
at a known period of time.

Recent application of the switching regression model to allocate workers into the primary and secondary labor markets is
considered to be the best solution to the classification problem of the empirical testing of the dual labor market theory.
In such models, normality of the error terms is assumed. This paper adopts the switching regression model to test the dual
labor market theory by assuming different distributions of the error terms. The test results strongly support the dual labor
market theory regardless of the assumption one makes about the error terms. However, the results indicate that different distribution
can lead to different percentage distributions of workers in the two segments. In particular, the normal distribution generates
more workers in the primary segment than the non-normal distributions. Therefore, care must be taken not to generalize the
type of industries or occupations that fall under the primary and secondary segments.

Summary. According to empirical studies, the wage differential by skills evolved non–monotonically in the past decades although the
relative supply of skilled labor steadily increased. The present paper provides a theoretical explanation for this finding.
In our setting, technological change intertemporally alters the human–capital investment incentives of heterogeneous individuals.
As a consequence of changing incentives, the time path of the relative wage is U–shaped while there is a rise in the share
of skilled workers.

Summary. We analyze an infinite horizon model where a seller who owns an indivisible unit of a good for sale has incomplete information
about the state of the world that determines not only the demand she faces but also her own valuation for the good. Over time,
she randomly meets potential buyers who may have incentives to manipulate her learning process strategically. We show that
i) the seller's incentives to post a high price and to experiment are not necessarily monotonic in the information conveyed
by a buyer's rejection; and ii) as the discount factors tend to one, there are equilibria where the seller always ends up
selling the good at an ex-post individually rational price.
