The world’s energy supplies are dependent not only on the producer countries’ production capacities and policies but also on adequate transport facilities. In fact, a shortage of vessels able to carry coal is widely expected to be a major bottleneck for the substitution of oil by coal on a large scale. Shipowner Peter M. Nomikos holds a different view. 相似文献

For the ten crop seasons 1979-80 to 1988-89, returns to producers in the Australian wheat industry were underwritten by a government-guaranteed price floor. Similar schemes operate in other rural industries (dairy, apples and pears, dried fruits). Although the underwriting provisions have only been triggered once (in the 1986-87 season), the provision of this scheme has acted to reduce the risk normally associated with returns to producers of wheat in all years of its operation. This reduction in risk has been granted free-of-charge by the Commonwealth Government. The guaranteed price can be viewed as a put option taken out by the Government on behalf of growers — it gives growers the option to sell to the Australian Wheat Board at this floor price. The aim of this paper is to apply to this underwriting arrangement the Black-Scholes formula for valuing options, in order to estimate the cost that growers would otherwise have had to pay to obtain cover (through put options) equivalent to the guaranteed price. We also estimate the magnitude of this form of assistance to the industry, which (until now) has not been taken into account unless the returns to growers fell below the guaranteed price. 相似文献

The World Bank's commodity price projections are widely used for various planning purposes. Two aspects of the Bank's projections of relative prices are studied in this paper. The first is whether the forecasts make efficient use of the information available at the time the forecast is made. The second is whether the forecasts predict future prices with greater accuracy than alternative forecasting methods. These matters are studied by comparing the World Bank's past price projections with the actual prices that were subsequently observed. The results show that, overall, the World Bank forecasts do not pass either test. First, the World Bank forecasts are informationally inefficient. Prediction error (projection minus actual price) tends to be positively correlated with the projections themselves. Although the direction of future price movements tends to be correctly predicted, the magnitude of these movements tends to be overpredicted. Second, the World Bank forecasts do not perform well even compared with the simplest of alternative forecasting methods - the prediction of no change. 相似文献

Despite the rapid growth of Internet banking (IB), customers in developing countries still hesitate to adopt this technology and its use in the Middle East remains low. This study aims to identify and examine the factors that predict behavioural intention and adoption of IB in Jordan. Four factors – hedonic motivation, habit, self-efficacy and trust – are proposed in a conceptual model. Data was collected by means of a survey with bank customers in Jordan. Structural equation modelling (SEM) was used to analyse the data. The results strongly supported the conceptual model. Further, hedonic motivation, habit, self-efficacy and trust were all confirmed to have a significant influence on behavioural intention. Trust was found to be strongly predicted by both hedonic motivation and self-efficacy. This study provides both academics and practitioners with an insight into the factors that can be used to encourage customer adoption of IB specifically in a Middle East context. 相似文献

This paper applies Plato’s cave allegory to Enron’s success and downfall. Plato’s famous tale of cave dwellers illustrates
the different levels of truth and understanding. These levels include images, the sources of images, and the ultimate reality
behind both. The paper first describes these levels of perception as they apply to Plato’s cave dwellers and then provides
a brief history of the rise of Enron. Then we apply Plato’s levels of understanding to Enron, showing how the company created
its image and presented information to support that image, and how the public eventually emerged from the cave to realize
the truth about Enron’s actual accounting practices and financial state, which led to the corporation’s downfall. We find
Plato’s allegory both useful in analyzing the relationship between Enron and the public and instructive about the power and
moral responsibility of Enron’s executives. 相似文献

Zusammenfassung Der weltweite Nachfrageeinbruch im Gefolge der Finanzkrise l?sst befürchten, dass die Preise auf breiter Front sinken. Dem
scheint die Geldpolitik jedoch mit verschiedenen Instrumenten begegnen zu k?nnen. Welche M?glichkeiten haben die Zentralbanken
über die traditionelle Geldpolitik hinaus? Was lehrt uns das japanische Beispiel? Welche makro?konomische Strategie ist jetzt
angebracht?

The contextual nature of the predictive power of statistically-based quarterly earnings models 总被引:2,自引:2,他引:0
We present new empirical evidence on the contextual nature of the predictive power of five statistically-based quarterly earnings
expectation models evaluated on a holdout period spanning the twelve quarters from 2000–2002. In marked contrast to extant
time-series work, the random walk with drift (RWD) model provides significantly more accurate pooled, one-step-ahead quarterly
earnings predictions for a sample of high-technology firms (n = 202). In similar predictive comparisons, the Griffin-Watts (GW) ARIMA model provides significantly more accurate quarterly
earnings predictions for a sample of regulated firms (n = 218). Finally, the RWD and GW ARIMA models jointly dominate the other expectation models (i.e., seasonal random walk with
drift, the Brown-Rozeff (BR) and Foster (F) ARIMA models) for a default sample of firms (n = 796). We provide supplementary analyses that document the: (1) increased frequency of the number of loss quarters experienced
by our sample firms in the holdout period (2000–2002) vis-à-vis the identification period (1990–1999); (2) reduced levels
of earnings persistence for our sample firms relative to earnings persistence factors computed by Baginski et al. (2003) during earlier time periods (1970s–1980s); (3) relative impact on the predictive ability of the five expectation models
conditioned upon the extent of analyst coverage of sample firms (i.e., no coverage, moderate coverage, and extensive coverage);
and (4) sensitivity of predictive performance across subsets of regulated firms with the BR ARIMA model providing the most
accurate predictions for utilities (n = 87) while the RWD model is superior for financial institutions (n = 131).
