Real Options Theory is often applied to the valuation of IT investments. The application of Real Options Theory is generally accompanied by a monetary valuation of real options through option pricing models which in turn are based on restrictive assumptions and thus subject to criticism. Therefore, this paper analyzes the application of option pricing models to the valuation of IT investments. A structured literature review reveals the types of IT investments which are valued with Real Options Theory in scientific literature. These types of IT investments are further investigated and their main characteristics are compared to the restrictive assumptions of traditional option pricing models. This analysis serves as a basis for further discussion on how the identified papers address these assumptions. The results show that a lot of papers do not account for critical assumptions, although it is known that the assumptions are not fulfilled. Moreover, the type of IT investment determines the criticality of the assumptions. Additionally, several extensions or adaptions of traditional option pricing models can be found which provide the possibility to relax critical assumptions. Researchers can profit from the results derived in this paper in two ways: First, it is demonstrated which assumptions can be critical for various types of IT investments. Second, extensions of option pricing models that relax critical assumptions are introduced. 相似文献

The EU is gradually systematizing its approach to ex ante regulation (notably with the publication of the recent regulatory framework for Electronic communications). Market definition is viewed as an essential first step in this, with the ‘Hypothetical Monopoly Test’ a useful conceptual tool for use in the assessment. This paper examines the use of this test for market definition when there are several differentiated goods or services under consideration. It sets out an analytic framework, discusses the pros and cons of using the test and illustrates its use in a Telecom context. 相似文献

Philanthropic venture capital (PhVC) is a financing option available for social enterprises that, like traditional venture capital, provides capital and value-added services to portfolio organizations. Differently from venture capital, PhVC has an ethical dimension as it aims at maximizing the social return on the investment. This article examines the deal structuring phase of PhVC investments in terms of instrument used (from equity to grant), valuation, and covenants included in the contractual agreement. By content analyzing a set of semi-structured interviews and thereafter surveying the entire population of PhVC funds that are active in Europe and in the United States, findings indicate that the non-distribution constraint holding for non-profit social enterprises is an effective tool to align the interests of both investor and investee. This makes the investor behaving as a steward rather than as a principal. Conversely, while backing non-profit social ventures, philanthropic venture capitalists structure their deal similarly as traditional venture capital, as the absence of the non-distribution constraint makes such investments subject to moral hazard risk both in terms of perks and stealing and social impact focus. 相似文献

The extension of adjustment assistance to those who have suffered trade‐related job displacement is widely supported on both sides of the economics of globalisation debate. The form that such assistance should take, namely wage insurance, is also the subject of wide agreement. Nevertheless, the formal economic rationales offered for such a policy are varied, including political economy arguments, equity arguments and market failure/ex post efficiency arguments. This note proposes an ex ante efficiency‐based rationale for the provision of adjustment assistance in the specific form of wage insurance. Job displacement imposes pecuniary externalities on displaced workers, which, in a complete markets setting, induce only shifts along the ex ante Pareto‐efficient frontier. However, when markets are incomplete, pecuniary externalities become welfare‐relevant. Without the possibility of diversifying or hedging the risk of pecuniary external diseconomies of job displacement using contingent claims, welfare is reduced ex ante. Wage insurance – whether publicly underwritten, privately underwritten (as in Shiller's (2003 ) ‘livelihood insurance’), or supplied on a mixed public/private basis – completes the market for contingent claims, allowing workers to diversify or hedge the risk of trade‐related pecuniary external diseconomies. By facilitating risk sharing, wage insurance removes an impediment to ex ante Pareto efficiency. Moreover, wage insurance affects not only post‐displacement behaviour by increasing the incentive to reacquire employment quickly, but it also affects pre‐displacement consumption and investment behaviour, in particular, lowering the threshold at which workers will be willing to undertake irreversible investment in industry‐specific skills. 相似文献

Recent developments in information technology (IT) are having a major effect on the way in which service firms are organised and produce their services. Much of the investment in IT has been made as a result of service firms' pursuit of a particular marketing strategy. However, investment in IT often brings with it such a variety of attributes that, once installed, a thorough reappraisal of the appropriate marketing strategy to be followed is required. 相似文献

After mentioning some deficiencies of the standard Black-Scholes model for the valuation of call options, we discuss discrete models which allow price changes of the underlying security at discrete time points only. It is shown that, given any distribution with a moment higher than 2, the paths of the Black-Scholes stock price process can be approximated uniformly as closely as one wishes by discrete paths generated by this distribution. Based on this approximation, discrete-time trading strategies are defined. Convergence (in measure and almost surely) of the corresponding financial gain processes is obtained. the results show the robustness of the Black-Scholes model. 相似文献

ABSTRACT Recent growth of personal computing and networked systems have resulted in Information Systems (IS) departments facing a heavy demand on their services. Based on internal marketing concepts, IS services need to use a measure of service quality for their internal customers. Studies carried out recently, suggest SERVQUAL as a possible measure of IS service quality. However, there are some issues that relate to their discriminant validity and appropriateness. A bottom-up approach to elicit service quality dimensions is explored using service encounters in a health organization. The results indicate that while the dimensions of responsiveness and assurance seem to be important, there is a need to re-look at these broad dimensions as more specific dimensions may be more appropriate for IS settings. 相似文献

服务定义的研究线索和理论界定 总被引:12,自引:0,他引:12
服务经济理论滞后于服务业的发展的重要原因之一是缺乏严谨统一的有关服务的理论定义。本文以服务定义的演变为逻辑线索,评析了自古典经济学以来的代表性概念,认为服务是不同经济主体之间通过使用权的让渡获得运动形态的使用价值。并使服务消费者获得消费利益或满足感。服务具有生产与消费的同步性,无形性和不可感知性,差异性和质量的不确定性,不可储存和无法运输性等特征。 相似文献
