Motivated by the implied stochastic volatility literature (Britten–Jones and Neuberger, forthcoming; Derman and Kani, 1997; Ledoit and Santa–Clara, 1998) this paper proposes a new and general method for constructing smile–consistent stochastic volatility models. The method is developed by recognising that option pricing and hedging can be accomplished via the simulation of the implied risk neutral distribution. We devise an algorithm for the simulation of the implied distribution, when the first two moments change over time. The algorithm can be implemented easily, and it is based on an economic interpretation of the concept of mixture of distributions. It can also be generalised to cases where more complicated forms for the mixture are assumed.  相似文献

Residential mortgage markets in both the United States and Canada have recently been dominated by instruments such as variable-rate and short-term rollover mortgages which require borrowers to assume a greater burden of interest rate risk. An outstanding question is whether this approach to risk allocation is Pareto optimal or whether there are other more effective methods of dealing with the risk created by interest rate volatility. This study examines the potential for shifting this risk from the mortgage market to the financial futures market. After considering the rationale for expecting that neither mortgage borrowers nor lenders wish to absorb the high levels of risk present in the existing financial environment, this study discusses the hedging of interest rate risk through financial futures markets. Empirical tests are then performed to evaluate the effectiveness of U.S. futures markets for hedging positions from the U.S. mortgage market. These results indicate that the interest rate risk inherent in residential mortgages can be substantially shifted through one or more positions in the existing futures contracts and long-term, fixed-rate mortgages may still be financially feasible under conditions of interest rate volatility.  相似文献

Using daily abnormal currency returns for the universe of countries with flexible exchange rates, we show local currency depreciations ahead of unscheduled, public sovereign debt downgrade announcements. Consistent with the private information hypothesis, the effect is stronger in lower institutional quality countries and holds after we control for concurrent public information and for publicly available rumors about the forthcoming downgrades. Our results persist when abnormal currency returns are adjusted for global carry and dollar risk factors, world equity and bond returns, as well as local stock market returns. Finally, the currency depreciations are permanent, providing evidence for a link between fundamentals and currency markets.  相似文献

The two general channels by which monetary policy impacts output are the neo-classical cost of capital channel and the credit channel. This paper decomposes the output response to a change in the stance of monetary policy to each of these channels. We use a unique industry level data set that measures the financial characteristics of firms operating at the industry level through time. We bring these financial characteristics formally into the regression analysis, thus allowing for a more precise identification of the two channels. The evidence indicates that both channels are active in the Canadian economy.  相似文献

Innovation, rule breaking and the ethics of entrepreneurship   总被引:2,自引:1,他引:1  
This article examines a feature of the ethics of entrepreneurship that is infrequently directly discussed, viz., rule breaking. Entrepreneurs are widely said to engage in rule breaking. Many examples of this appear in popular and academic literature. But how may this be integrated into an account of the ethics of entrepreneurship? One response would be that when entrepreneurs break legal and moral rules then what they do is wrong and ought to be condemned. There is a great deal to be said for this rule model of entrepreneurial ethics. However, this view is also mistaken. Instead, this article defends a virtue-based account of the ethics of entrepreneurship in which certain instances of rule breaking, even if morally wrong, are nevertheless ethically acceptable and part of the creative destruction that entrepreneurs bring not only to the economy but also to morality.  相似文献

This study uses a sample of plant closings as the testing stage to examine the financial consequences of variant environmental performance records and stakeholder pressure levels. It compares 117 manufacturing facilities closing down between 1998 and 2000 to 351 facilities surviving through this period, along four measures of environmental performance. It shows that in the ten years prior to closure, closing facilities reduce their toxics emissions relatively more and incur somewhat stronger community and regulatory pressures than surviving ones. The results persist through alternative versions of the model and suggest that the environmental performance of closing facilities is at least as good as that of surviving ones. The mix of environmental practices of closing facilities differs from that of surviving ones with the former engaging in significantly less recycling of waste than the latter. Closing facilities focus more on end-of-pipe measures while surviving ones engage in more pro-active strategies, consistent with evidence in the literature of a positive relation between pro-active environmental practices and performance. Stakeholder pressures, in some cases (e.g., in pollution intensive industries), may be associated with unrecoverable costs to facilities, including closure, depending on the environmental management choices of the facilities.  相似文献

This paper focuses on product-harm crises and examines consumer responses associated with product defect in three time periods (i.e., 3 days, 3 months and 1 year after a crisis). An experiment was conducted based on three widely accepted- influences on product-harm crisis management (i.e., crisis extent, social responsibility and organizational responses). The fourth influencing factor, time, was introduced in the present study. The four-factor model for measuring the effectiveness of product-harm crisis management was tested with particular attention to the impact of time. Crises were described in scenarios for a fictitious mobile phone. The results demonstrate that the effects of a crisis are minimal a few months after the crisis has occurred. Consumers tend to “forget” about the crisis and its effects, especially in cases when the company is socially responsible, and when the company issues a voluntary recall of its product.  相似文献

The energy and environmental crises are important problems facing the United States today. With less than 6% of the world's population, the U.S. accounts for 47% of the world's automobiles and nearly 35% of the total energy demand. Automobiles consume nearly 14.5% of the total energy demand and are the major source of air pollution. Whiel there are many potential solutions for the energy and environmental crises, this paper specifically focuses on how the electric car can be a partial answer to the complex problem of personal transportation. The paper specifically discusses the role of marketing in bridging the gap between technology and the consumer. On the basis of an extensive exploratory study, the authors contend that there is sufficient interest among consumers for an economical, pollution-free, electric car. Understanding the consumer's need and developing a product that is feasible, considering existing technology, is the role that marketing must play.  相似文献

The purpose of this paper is to describe the implications of the collective model of household behavior for the methods used to estimate the economic value of non-marketed environmental resources. After demonstrating how the separability restrictions inherent in the collective model allow individual preference and household income allocation choices to be distinguished, the paper demonstrates how the framework can be used to recover Hicksian consumer surplus. An algebraic example is used to illustrate how the framework can be used in valuing environmental resources.  相似文献
