This paper presents an alternative approach to derive the Breeden-Litzenberger valuation formula, which expresses the price of an arbitrary derivative security in terms of call options' prices. This valuation formula follows from the observation that a continuous derivative security can be replicated by a portfolio including a bond and call options with all possible exercise prices. Discrete terms are added to the original Breeden-Litzenberger formula to reflect possible discontinuities of the call option price's derivative with respect to the exercise price. These discontinuities are subsequently shown to correspond to mass points of the probability distribution of the stock price. Several applications of the Breeden-Litzenberger valuation formula are demonstrated. 相似文献

Venture Capital Funds, Financial Foreign Direct Investment and the Generation of Local Comparative Advantage in the Technology Sector in Israel 总被引:1,自引:0,他引:1
The rapid development of a new comparative advantage in thehi-tech sector in Israel in the period 1995–2005 providesan example of a new form of foreign direct investment (FDI).Unlike traditional FDI, this new form of international investment,that we dubbed financial foreign direct investment (FFDI), involvescapital flows from developed countries to small countries andto the emerging markets. The providers of this capital, definedin our study as "sector-specific capital", are financial andrisk intermediaries like venture capital funds and private equityfunds. Like multinational enterprises they transfer factorsof production across borders seeking to maximize their value.In doing so, they are a part of a process of generating newcomparative advantages. We focus on the case of Israel and showthat, due to the inherent asymmetry, it takes government actionto trigger the process of importing sector-specific capitalto Israel primarily from the US capital market, but once theprocess has begun, it has led to economic growth via reducingtangible and intangible trade costs, creating trust and thusgenerating competitive advantage for innovative technology firmsfrom Israel in the global markets. 相似文献

The basic Lucas model for risky R&D projects is revisited. New solutions for optimal expenditures are explored by exploiting the merits of the theory of differential equations. After applying the calculus of variations, a nonlinear differential equation is presented whose solution provides the optimal control for a constant conditional-completion density function and different time-dependent return models. New, exact, and approximate solutions are presented and discussed. It is found, for the class of risky R&D projects under study, that the behavior over time of the optimal expenditure is functionally similar to that of the expected return. 相似文献

Assessing Mobility Barriers In Dynamic Strategic Groups Analysis 总被引:1,自引:0,他引:1
The Mobility Barriers Paradigm (Caves and Porter, 1977) has strongly influenced research in strategic management, particularly in the areas of competitive analysis and strategic groups. In this article we develop a procedure called MOBIUS, based on ‘match ratios’(MRs), in order to identify those competitive variables which act as mobility barriers in a particular industry. We also attempt to classify mobility barriers in terms of the degree of observed mobility around key strategic variables and the extent to which change is desired on these variables. the MOBIUS procedure is illustrated briefly in the context of the pharmaceutical industry. 相似文献

Consider a futures contract on Country 2’s currency denominated in Country 1’s currency, and its reciprocal, a futures contract on Country 1’s currency denominated in Country 2’s currency. Because both are marked to market in different currencies, the relationship between the associated futures prices is not simple. We investigate the functional relationship between these two futures prices. 相似文献

This paper models how regulatory attempts to protect the privacy of consumers' data affect the competitive structure of data‐intensive industries. Our results suggest that the commonly used consent‐based approach may disproportionately benefit firms that offer a larger scope of services. Therefore, though privacy regulation imposes costs on all firms, it is small firms and new firms that are most adversely affected. We then show that this negative effect will be particularly severe for goods where the price mechanism does not mediate the effect, such as the advertising‐supported Internet. 相似文献

In many countries laws are not enforced against visibly present illegal immigrants. The visibly present illegal immigrants also tend to be concentrated in particular sectors. We explain such permissible illegal immigration in an endogenous-policy model where selective sector-specific illegality transforms illegal immigrants from non-sectorally specialized to sector-specific factors of production. Under initial conditions where no immigrants are present, the median voter opposes immigration. When, however, a population of illegal immigrants has accumulated, ongoing illegal immigration becomes an endogenous equilibrium policy, at the same time that a majority of voters opposes legal immigration and opposes amnesty that would legalize the immigrants' presence. We also establish a basis for domestic voters preferring that illegal immigrants be employed in service rather than traded-goods sectors. 相似文献

Prior research into the link between new product development and market segmentation has focused on two main approaches: (1) design, segment, and do limited competitive evaluation; and (2) segment first, design second. This paper proposes a third approach, which is to simultaneously design, perform segmentation according to benefit and to evaluate against competitive designs. This research uses a benefit segmentation technique based on conjoint analysis (or other techniques that relate product attributes to consumer utility) in which the segments emerge simultaneously with the design based on certain design principles or “strategies.” Herein a method is proposed to narrow down the many possible feasible designs (combinations of attributes) to a finite set and to examine the appeal of each design. Five distinct design strategies are proposed for modeling and studying competitive reaction. These include “traditional” ones such as differentiation and new ones whose fringe customers have high utility. The paper shows that these five strategies are adequate for modeling competitive reaction using simulation. Another contribution of the paper is the way competitive reaction is modeled. In generating and evaluating a design the desire herein is also to assess the defensibility of the design and include it in the evaluation criteria. These issues are addressed by decomposing the solution procedure into two phases. In the first phase, different optimal designs are created based on predefined product development strategies. In the second, these optimal designs are compared against one another with regard to market share and potential to secure market leadership. This work shows that the nature of competition as well as the variability of customer preferences are critical to how a strategy performs. This process uncovers a surprisingly robust design strategy—developing attributes such that a “lower fringe” is most satisfied—that even achieves market dominance under certain conditions. This methodology is also applied to partworth data on refrigerators, which provides a concrete example of the concepts and demonstrates results consistent with the propositions developed earlier in the paper. 相似文献

Pricing methodologies in Medicare vary from one component of the system to another, often leading to conflicting incentives. Failure to recognize linkages may result in inefficient allocation of resources and higher overall costs. To motivate the analysis, I derive pricing rules for a welfare-maximizing regulator. I show that while optimal inpatient payments are standard Ramsey prices, optimal outpatient payments must incorporate net loss due to unnecessary hospitalizations, as well as supply elasticities. Ignoring this leads the myopic regulator to underprovide preventive services. The dialysis program is a useful case for empirical investigation, since payments for maintenance care are more rigidly determined than payments for related hospital care. Given constant prices, empirical analysis focuses on the effect of dialysis intensity on hospital use. Results indicate that greater dialysis intensity reduces hospital use, even at levels considered more than adequate. A simple cost-benefit calculation suggests that for every dollar of additional spending on outpatient intensity, about $2 in hospital expenditures can be saved. This suggests that the current pricing structure within aspects of the Medicare program is inefficient, underscoring the problem of regulatory myopia. 相似文献
