In this paper we present an alternative model for pricing exotic options and structured products with forward-starting components.
As presented in the recent study by Eberlein and Madan (Quantitative Finance 9(1):27–42, 2009), the pricing of such exotic
products (which consist primarily of different variations of locally/globally, capped/floored, arithmetic/geometric etc. cliquets)
depends critically on the modeling of the forward–return distributions. Therefore, in our approach, we directly take up the modeling of forward variances corresponding to the tenor
structure of the product to be priced. We propose a two factor forward variance market model with jumps in returns and volatility.
It allows the model user to directly control the behavior of future smiles and hence properly price forward smile risk of
cliquet-style exotic products. The key idea, in order to achieve consistency between the dynamics of forward variance swaps
and the underlying stock, is to adopt a forward starting model for the stock dynamics over each reset period of the tenor
structure. We also present in detail the calibration steps for our proposed model. 相似文献

Abstract. This paper is the first to provide a micro‐level analysis of the impact of intercity rail connections on property prices. We use the variation in mainline accessibility provided by the reorganization of the rail system in post‐unification Berlin to isolate accessibility effects from correlated individual location effects. Evidence does not support the existence of localized effects on location productivity and household utility. While the city, since unification, has undergone significant changes in its spatial structure, these effects cannot be attributed to the new transport concept. Our findings question the justification for committing substantial public funds to downtown rail redevelopment projects. 相似文献

Empirical papers show that successful exporting firms either use unaffiliated foreign trade intermediaries or own foreign wholesale subsidiaries. However, conventional trade theory models assume that producers can directly access foreign consumers. We introduce intermediaries in an international trade model where producers differ with respect to productivity as well as regarding their varieties' perceived quality and tradability. Trade intermediation is prone to frictions owing to the absence of enforceable cross‐country contracts while own wholesale subsidiaries require additional capital investment. The sorting pattern of firms depends on their degree of competitive advantage; the equilibrium prevalence of intermediation in the industry depends negatively on the heterogeneity among producers, and the market‐specificity of goods, and positively on expropriation risk. Using sectoral US export data by destination country, we confirm the empirical validity of these predictions. 相似文献

Electronic listening (eListening) is an innovation that potentially provides patients and other users with the right answer in the right place at the right time. Thus, eListening can potentially improve service flexibility, adaptability and quality. The main purpose of this paper is to investigate the extent to which new web-based service delivery channels, which we refer to as health-portals (he-portals), facilitate eListening in the Spanish public healthcare sector. In this paper, we investigate the relative importance and significance of hospital size and three different types of information and communications technologies (Internet, groupware and collective systems) on the use of eListening through an empirical investigation of 300 Spanish public he-portals. Our main conclusion is that the implementation of Internet systems alone does not guarantee the development of effective eListening. In addition, we demonstrate that hospital size does not affect the level of eListening achieved by hospitals. 相似文献

Since the deregulation of the coffee market in 1989, price crises are proof of the uncertainty and risk around coffee growers’ income, particularly for small producers who, in the case of Mexico, have taken action such as the conversion of their traditional crops into the organic production system which, besides the ecological priority, allows them to get a higher income than from conventional coffee. In this document we model as real investment options (RIO) the possibility of conversion from one system into the other one also including the feasibility of abandoning this strategic decision. 相似文献

We compare the performance of various matching estimators using a novel approach that is feasible in the absence of experimental data. We estimate a structural model of hospital choices and catheterization for Medicare heart attack victims using hospital chart data on patient heterogeneity. With the estimated structural parameters, we simulate data for which the treatment effect is known. We find that as measures of individual heterogeneity are added to the controls, matching estimators perform well. However, the estimators do a poor job recovering the true treatment effect when measures of individual heterogeneity are unavailable. Copyright © 2010 John Wiley & Sons, Ltd. 相似文献

This paper presents an exploratory input–output analysis of the nonprofit sectors in former West Germany and the USA based on the conceptual and data structure provided by the System of National Accounts. When compared with the USA, the West German nonprofit sector catered more to government demands. A higher proportion of West German nonprofit services went to government and a smaller proportion went to households. In terms of the multiplier effect of nonprofit output, we find that an additional dollar of nonprofit services delivered to households and/or government induced indirectly an additional 83 cents of business output in the USA. By comparison, West Germany's nonprofit sector had a lower multiplier effect, with 43 Pfennig per DM1. We also find that businesses have a much larger stake in nonprofit production as intermediate suppliers when compared to their role as intermediate consumers. The economic position the nonprofit sector occupies in both countries is that of a producing sector, taking inputs from businesses and providing outputs for households and governments. This general structural characteristic suggests that the nonprofit sector is particularly sensitive to changes in government policies as well as to shifts in private household incomes, yet relatively insensitive to demand changes in other industries. 相似文献

The purpose of this paper is to examine the factors that drive or prevent companies' implementation of sustainable supply chain management (SSCM) practices. To this end, we interviewed 29 senior managers from 23 New Zealand‐based companies. The key reported drivers were customer expectation, top management commitment, moral and ethical values of managers, reputation management, and economic and operational benefits. Conversely, cost concerns, strategic and structural restraints, supplier and customer issues, and a lack of effective regulations were cited as critical obstacles to SSCM implementation. Thus, the evidence from our findings provides support for both instrumental and normative logics for SSCM implementation. The findings further indicate that, in general, instrumental and normative logics are congruent; however, varied tensions arise when managers seek to simultaneously address competing yet desirable SSCM aspects. Accordingly, we argue that it is imperative to understand, work through, and manage such tensions as balancing divergent sustainability aspects holds considerable potential for successful SSCM implementation. 相似文献

Globalisation of world economy brings new and more complex demands to business systems. In order to respond to these trends, business systems apply new paradigms that are inevitable reflecting on management metasystems – quality assurance (QA), as well as on information technology (IT) metasystems. Small and medium enterprises (in particular in food industry) do not have possibilities to access external resources to the extent that could provide adequate keeping up with these trends. That raises the question how to enhance synergetic effect of interaction between existing QA and IT metasystems in order to overcome resource gap and achieve set goals by internal resources. The focus of this article is to propose a methodology for utilisation of potential of quality assurance document management system (QDMS) as prototypical platform for initiating, developing, testing and improving new functionalities that are required by IT as support for buiness system management. In that way QDMS plays a role of catalyst that not only accelerates but could also enhance selectivity of the reactions of QA and IT metasystems and direct them on finding new functionalities based on event-driven paradigm. The article tries to show the process of modelling, development and implementation of a possible approach to this problem through conceptual survey and practical solution in the food industry. 相似文献

We study the effect of fiscal rules on a country's credit rating and their interaction with financial development. We build a rich set of panel data, which includes a novel index for the strength of fiscal rules. We find a positive and significant effect of fiscal rules on sovereign ratings. We also find that this effect is attenuated in economies with a more developed domestic financial system. Therefore, financial markets act as a substitute for fiscal rules in lowering the default risk assessed by credit rating agencies. This substitution effect between fiscal rules and financial development is mostly triggered through the monitoring and enforcement dimension of fiscal rules. 相似文献
