A bstract . The geostationary arc is an orbit in space in which a satellite , 22,300 miles up, moving at the speed at which the earth revolves, can continue to hover over a continent on earth, monitoring weather and military activities, rebroadcasting entertainment and information programs, newspaper and magazine printing plates and particularly communications. In the latter use it replaces surface microwave relay transmitters every 30 miles (which replaced the much more expensive long landlines ), at an estimated savings of more than half a billion dollars annually for this use alone. Because the orbit cannot accommodate all the applicants for slots within it, the Federal Government should grant, for an adequate fee, three year licenses, raising the fee on renewal to absorb the annual economic rent. 相似文献

This article argues that conservatism as a personal value among senior managers significantly affects corporate performance. A scale to measure conservatism was developed and its measurement properties were tested on several hundred executives. Empirical results were consistent with the hypotheses that conservatism among senior management teams is negatively associated with the firm's social responsiveness as well as certain aspects of financial performance. 相似文献

The purpose of this paper is to provide a theoretical analysis of the implications of increased competition among depository financial institutions for the optimal conduct of monetary policy with respect to the ultimate goals of price and output stability. In the context of a general equilibrium model which includes rational expectations and a market for bank deposits, it is shown that a rise in bank rivalry for deposits produces a more steeply sloped LM schedule. Under a system of lagged required reserve accounting, this fact has no effect on the optimal conduct of monetary policy, which requires an operating procesure designed to target a market interest rate. However, under a system of contemporaneous reserve accounting, this fact implies that less emphasis should be placed on a market interest rate as a variable upon which the Fed's setting of reserves should be conditioned. 相似文献

This paper explores two ideas: that the competitive inteligence-gathering efforts of industrial marketers differ in purpose from those of consumer marketers, and that the scope of those efforts can be explained by a model incorporating purpose, size, competitive environment, and strategy. Based on data provided by employees of 151 firms, support is found for both of the basic ideas explored. 相似文献

An analysis of control policies for a two-stage supply chain with subcontractors at each stage is presented when decisions at each stage concerning safety stocks, backorders, and subcontracting are made jointly or in a decentralized manner. The inventory/admission control policies considered are base stock, echelon base stock and partial backordering, and the objective is to maximize the mean profit rate of the system. The optimal control parameters are found by exhaustive search using Markov chains. From numerical examples it appears that the policies which manage jointly sales and production levels in each stage provide much higher overall (system) profits than decentralized policies, although the latter are individually more profitable for the second stage. In addition, partial backordering provides the system with an extra profit above those that result from the lost sales (no backordering) and complete backordering policies. Finally, a number of numerical results show the impact of variations in certain system parameters on the optimal control parameters and the corresponding profit. 相似文献
