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

A survey conducted in Mississippi, Texas, Indiana, and Nebraska elicited producers' preferences for various farm policy changes. This permitted examination of the diversity of preferences that single-state studies have not allowed. Five policy choices, including deficiency payments, loan programs, crop insurance, export programs, and disaster payments were examined. Logit model results predicting producer preferences for each of the five dichotomous policy choices are reported. Explanatory variables based on expected utility theory such as risk aversion, price and yield variability, and price–yield correlation are significant in various models. 相似文献

Measuring and reporting the nation's finances are based on government budgeting, national accounting and the accounting discipline, which are all fundamentally different. The nature and extent of these differences has rarely been made explicit. The most visible change in the accounting discipline in the second half of the 20th century was the emergence of codifications of accounting, with concomitant policy–making processes that allow for 'due process'. One result is that each codification is different within countries such as the UK and US, as well as between them. The codifications for government budgeting and national accounting are different again. The article offers some broad conclusions. 相似文献

Transition from a planned command economy to a market economy means tearing down a socio-economic setting where everybody follows orders and nobody bears individual responsibility for anything. The absence of personal responsibility does not promote ethical behavior in any walk of life. Today, the malnourished business ethics in the former Soviet Union creates a critical obstacle to economic development. The paucity of new official rules governing the conduct of business makes the transition process painful and difficult to people habituated to numberless rules and regulations. The first part of this paper surveys the most visible unethical business practices that have been reported by the Western media and those that are causing the largest number of complaints by the local governments and businessmen. The second part of the paper looks at ethical problems that have been under-reported. 相似文献

In September 1991 the Greek Consumer Protection Act No. 1961 was enacted. Chapter 2 of this Act establishes a legal framework for product safety. This framework has the dual aim of securing deregulation in the Greek market while maintaining effective consumer protection. This paper analyses the main features of this framework and demonstrates its inadequacies. It also investigates the extent to which these inadequacies could jeopardise an effective protection of consumers' interests. The paper concludes by emphasising that effective protection of consumers can only be achieved by supporting the general safety requirement with adequate accident-surveillance systems, mechanisms for investigation of risks, unambiguous risk-assessment criteria, creation of a comprehensive set of supporting standards that offer a high level of protection, effective control of the safety of products by the authorities, and real possibilities for consumer organisations to participate in the whole process.

Zusammenfassung Die Sicherheit des Verbrauchers in Griechenland: eine Analyse des Verbraucherschutzgesetzes von 1991 Im September 1991 trat das griechische Verbraucherschutzgesetz in Kraft. Kapitel 2 des Gesetzes führt einen rechtlichen Rahmen für die Sicherheit von Produkten ein. Dieser Rahmen verfolgt das Ziel der Deregulierung auf dem griechischen Markt bei zugleich wirksamem Verbraucherschutz. Der Beitrag analysiert die wesentlichen Aspekte dieses Rahmens und stellt seine Schwächen dar. Er prüft, inwieweit diese Schwächen einem wirksamen Verbraucherschutz entgegenstehen können, und hebt hervor, da\ wirksamer Verbraucherschutz nur durch Stärkung der allgemeinen Sicherheitsbestimmungen erreicht werden kann. Dafür sind erforderlich ein angemessenes Unfallüberwachungssystem, Regelungen für die Untersuchung von Risiken, eindeutige Kriterien für die Bewertung von Risiken, die Entwicklung umfassender Kriterien zur Gewährleistung eines hohen Schutzniveaus, die wirksame Kontrolle der Produktsicherheit durch die Behörden, sowie für die Verbraucherorganisationen die faktische Mitwirkungsmöglichkeit an der gesamten Entwicklung.

In 1986 The O.M. Scott & Sons Company, the largest producer of lawn care products in the U.S., was sold by the ITT Corporation in a divisional leveraged buyout. The company was founded in Marysville, Ohio in 1870 by Orlando McLean Scott to sell farm crop seed. In 1900, the company began to sell weedfree lawn seed through the mail. In the 1920s, the company introduced the first home lawn fertilizer, the first lawn spreader, and the first patented bluegrass seed. Today, Scott is the acknowledged leader in the “do-it-yourself” lawn care market, with sales of over $300 million and over 1500 employees. Scott remained closely held until 1971, when it was purchased by ITT. The company then became a part of the consumer products division of the huge conglomerate, and operated as a wholly-owned subsidiary for 14 years. In 1984, prompted by a decline in financial performance and rumors of takeover and liquidation, ITT began a series of divestitures. Over the next two years, total divestitures exceeded $2 billion and, after years of substandard performance, ITT's stock price significantly outperformed the market. On November 26, 1986, in the midst of this divestiture activity, ITT announced that the managers of Scott, along with Clayton & Dubilier (C & D), a private firm specializing in leveraged buyouts, had agreed to purchase the stock of Scott and another ITT subsidiary, the W. Atlee Burpee Company. The deal closed on December 30. Clayton & Dubilier raised roughly $211 million to finance the purchase of the two companies. Of that $211 million, almost $191 milion, or 91% of the total, was debt: bank loans, subordinated notes, and subordinated debentures. The $20 million of new equity was distributed as follows: roughly 62% of the shares were held by a C & D partnership, 21% by Scott's new subordinated debtholders, and 17.5% by Scott management and employees. After this radical change in financial structure and concentration of equity ownership, Scott's operating performance improved dramatically. Between the end of December 1986 and the end of September 1988, sales were up 25% and earnings before interest and taxes (EBIT) increased by 56%. As shown in Table 1, this increase in operating earnings was not achieved by cutting back on marketing and distribution or R & D. In fact, spending on marketing and distribution increased by 21% and R & D spending went up by 7%. Capital spending also increased by 23%. 相似文献

Philosophers have constituted business ethics as a field by providing a systematic overview that interrelates its problems and concepts and that supplies the basis for building on attained results. Is there a properly theological task in business ethics? The religious/theological literature on business ethics falls into four classes: (1) the application of religious morality to business practices; (2) the use of encyclical teachings about capitalism; (3) the interpretation of business relations in agapa-istic terms; and (4) the critique of business from a liberation theological point of view. Theologians have not adequately addressed the questions of whether there are particular theological tasks in the field as they define it, and whether, if they define it, the theological definition is different from the philosophical. 相似文献

This article uses a nonparametric test based on the arc‐sine law (see, e.g., Feller, 1965 ), which involves comparing the theoretical distribution implied by an intraday random walk with the empirical frequency distribution of the daily high/low times, in order to address the question of whether the abandonment of pit trading has been associated with greater market efficiency. If market inefficiencies result from flaws in the market microstructure of pit trading, they ought to have been eliminated by the introduction of screen trading. If, on the other hand, the inefficiencies are a reflection of investor psychology, they are likely to have survived, unaffected by the changeover. We focus here on four cases. Both the FTSE‐100 and CAC‐40 index futures contracts were originally traded by open outcry and have moved over to electronic trading in recent years, so that we are able to compare pricing behavior before and after the changeover. The equivalent contracts in Germany and Korea, on the other hand, have been traded electronically ever since their inception. Our results overwhelmingly reject the random‐walk hypothesis both for open‐outcry and electronic‐trading data sets, suggesting there has been no increase in efficiency as a result of the introduction of screen trading. One possible explanation consistent with our results would be that the index futures market is characterized by intraday overreaction. © 2004 Wiley Periodicals, Inc. Jrl Fut Mark 24:337–357, 2004 相似文献
