The objective of this paper is to examine the effects of marking‐to‐market of futures contracts on the price differential between futures and forward contracts based on the predictions of the Cox, Ingersoll and Ross (1981) (CIR) model. Cox et al ., (1981) derive a series of propositions with respect to the relationship between futures and forward prices and a set of testable implications. These are tested empirically in this paper using Australian data from November 1991 to June 1997. The results provide evidence of the presence of significant futures and forward price differences, where the futures price is consistently below the forward price. Only partial support is found for the Cox et al ., (1981) propositions, implying that the effect of marking‐to‐market is not able to fully account for the price differential. Therefore, it is not possible to rule out the influence of other institutional factors on the futures‐forward price difference. 相似文献

A priority for the post‐apartheid government was the extension of basic infrastructure services to the vast majority of citizens that were not serviced under apartheid. The Reconstruction and Development Programme set objectives for each of these utilities that would be achieved in the first decade of democracy, while departmental policy aimed to find means of achieving these targets. The strategy of choice in most sectors was one of ambitious roll‐out targets being set for utility operators. Targets were set for individual residential service (‘universal service’) and for community service outside of individual homes (‘universal access’). While most utilities remained under public ownership, in telecommunications there was partial privatisation of the incumbent Telkom and the entry of privately owned mobile cellular operators. This article examines how roll‐out targets and licence conditions for universal service have performed in this sector where private operators exist. It examines the failure of the Telkom licence and draws out some lessons for policy. 相似文献

This paper provides some new evidence on the behaviour of cross-country growth rates. We reject the linear model commonly used to study cross-country growth behaviour in favour of a multiple regime alternative in which different economies obey different linear models when grouped according to initial conditions. Further, the marginal product of capital is shown to vary with the level of economic development. These results are consistent with growth models which exhibit multiple steady states. Our results call into question inferences that have been made in favour of the convergence hypothesis and further suggest that the explanatory power of the Solow growth model may be enhanced with a theory of aggregate production function differences. 相似文献

The importance of evaluating a discipline system from an ethical perspective is considered. Disciplinary practices in contemporary organizations are frequently characterized by managers having to choose from among alternative courses of corrective action. Since the selected alternative may have serious consequences for the individuals involved, its rightness or wrongness is of concern. The pattern of these choices reflects the overall disciplinary practice of the organization, and is an issue that warrants attention from an ethical perspective. Basic schools of thought that influence contemporary discipline practices are discussed and suggestions are made for conducting an evaluation of the ethical nature of a discipline system. 相似文献
