Asian‐Basket‐type moving‐window contracts are an increasingly used risk‐management tool in the North American hog sector. The moving‐window contract is decomposed into a portfolio of a long Asian‐Basket put and a short Asian‐Basket call option. A projected break‐even price is used to determine the floor price, and then Monte Carlo simulation methods are used to price both a moving‐ and a fixed‐window contract. These methods provide unbiased pricing of fixed‐ and moving‐window hog‐finishing contracts of 1‐year duration. © 2003 Wiley Periodicals, Inc. Jrl Fut Mark 23:1047–1073, 2003 相似文献

Environmental uncertainty is a fact of life in today's supply chains. In this paper we develop a model of environmental uncertainty, supply chain (SC) relationship quality and SC performance. We use data from the electronics sector in Ireland to test our model. Our results provide mixed support for the model, with the moderating role of both demand and supply uncertainty being supported, but technological uncertainty not supported. We reflect on these findings and suggest a research agenda based on our results. 相似文献

In the General Theory, Keynes argued that expectations about future bond prices tend to be “sticky”. A rise in bond prices causes more investors to “join the bear brigade” and so increases the aggregate demand for money. Since Tobin's classic article on liquidity preference, this explanation of the downward sloping demand for money curve has largely disappeared from the literature. This note introduces sticky expectations into the Tobin framework. It shows that the existence of such stickiness does not necessarily cause the demand for money to be more elastic because investors have expectations about the variance of future bond prices as well as about their mean. A sufficient condition for a more elastic demand for money under sticky expectations is that the Pratt-Arrow coefficient of relative risk aversion be either constant or decreasing in wealth. 相似文献

This paper integrates the analytic hierarchy process (AHP) with scenario analysis techniques to explore the commercialization of future hydrogen fuel processor technologies. AHP is a multi-attribute decision analysis tool useful for evaluating decisions with multiple criteria and alternatives. In this paper, AHP is extended using a technique called perspective-based scenario analysis (PBSA). In PBSA, scenario analysis is conducted based on potential future decision-maker perspectives that are integrated into the AHP framework. This paper discusses this method and applies it to the evaluation of hydrogen fuel processor technologies 15–20 years hence. The results provide an added layer of insight into the opportunities and barriers for the commercialization of these technologies as well as the methodological opportunities for using AHP and PBSA as a futures tool. 相似文献

This paper examines the role of patent licensing in the age of outsourcing. When firms rely on outsourced inputs, a patent
holder’s decision to license has both competitive and supplier pricing effects. By issuing a license, the firm increases competition
in the product market. At the same time, the need to make royalty payments “weakens” the firm’s rival, making it more sensitive
to supplier pricing. The supplier responds by softening pricing terms, and the firm benefits by siphoning some of these gains
via the license fee. Not only can the licensor gain, but all other parties (the licensee, supplier, and consumers) can also
benefit. This role of licensing presents additional considerations for regulators shaping patent laws.

The way in which cyclical fluctuations in activity in the U.K. economy affect factor income shares and the channels through which these effects work through to the size distribution of income are traced. Using National Accounts data, the impact of an upturn in activity in increasing the shares of profits and self-employment income in factor incomes, and of self-employment and rent, interest and dividends in personal incomes, is quantified. Using Family Expenditure Survey micro-data, the resulting shift in decile shares in personal income, which is towards the top of the size distribution, is estimated. 相似文献

Summary. We consider an environment where individuals sequentially choose among several actions. The payoff to an individual depends on her action choice, the state of the world, and an idiosyncratic, privately observed preference shock. Under weak conditions, as the number of individuals increases, the sequence of choices always reveals the state of the world. This contrasts with the familiar result for pure common-value environments where the state is never learned, resulting in herds or informational cascades. The medium run dynamics to convergence can be very complex and non-monotone: posterior beliefs may be concentrated on a wrong state for a long time, shifting suddenly to the correct state.Received: 6 January 2005, Revised: 5 May 2005, JEL Classification Numbers:

The conjunctures in question are the approach of a new millennium and the likely sag of the economy into a long-wave (Kondratiev) trough as that millennium arrives. Will there be yet another wave of apocalyptic expectation? An answer is sought in the nature and extent of American prophecy belief and in historic associations between millennial surges and long-wave troughs. 相似文献
