This paper tests the fair‐game efficient‐markets hypothesis for the natural gas futures prices over the period 1990 through 2003. We find evidence consistent with the Keynesian notion of normal backwardation. Regressing the future spot prices on the lagged futures prices and using the Stock‐Watson (1993) procedure to correct for the correlation between the error terms and the futures prices, we find that natural gas futures are biased predictors of the corresponding future spot prices for contracts ranging from 3 to 12 months. These results cast a serious doubt on the commonly held view that natural gas futures sell at a premium over the expected future spot prices, and that this bias is due to the systematic risk of the futures price movements represented by a negative “beta.” We also find evidence for the Samuelson effect. © 2005 Wiley Periodicals, Inc.

The reduction of grain shipments and the export ban for computers imposed by the US Administration in response to the Soviet occupation of Afghanistan was supplemented, late in February 1980, by prohibition of deliveries of phosphates to the Soviet Union. President Carter has not yet urged the western industrialized states to participate in economic sanctions against the USSR, but a comprehensive embargo is still under discussion. In this connection it is not only the expediency of an embargo against the Soviet Union which is at issue, but the question how the East-West trade is to be conducted and what is, in the long run, to be regarded as normal in this field. 相似文献

This essay discusses the implications of the idea that the Keynesian premise implies deviations between the normal and the average degrees of utilization. A system of equations called the ``average system'' is proposed for the study of average values, as distinct from normal values, by way of a hypothetical steady- state growth path for each sector. A long-period implication of the short-period under-utilization of productive capacity is presented in terms of a two-sector model. 相似文献

This paper applies theory and research examining errors in complex organizational systems to the problem of individual and collective morality in organizations. It is proposed that because of the nature of complex organizations, unjust outcomes can (and will) result from organizational actions even when all organization members have acted responsibly. The argument that complex organizations are therefore immoral is considered and rejected. Instead, the paper argues that morality in complex organizations begins with "heedful interrelating" among individual organization members. The paper concludes with a discussion of organizational processes and structures that promote heedful interrelating. 相似文献

This paper deals with the normal utilization rate in the Sraffa framework. It further presents two arguments about the utilization controversy surrounding the neo-Kaleckian theory of growth and distribution: First, it shows that the normal utilization rate is generally not independent of demand and the growth rate, and this result does not rely on the neo-classical production function and other restrictive assumptions. Second, it argues that endogenizing the normal utilization rate is not a general solution for the utilization controversy. 相似文献
