The effects of divestiture,privatization, and competition on productivity in U.S. and U.K. telecommunications 总被引:1,自引:0,他引:1
John E. Kwoka Jr. 《Review of Industrial Organization》1993,8(1):49-61
The telecommunications industries in the United States and the United Kingdom have undergone massive changes during the 1980s. This paper decomposes the total factor productivity growth of AT&T and British Telecom into their various components. It finds that while a great deal of the productivity increases apparently resulted from continuing scale economies, competition for AT&T and privatization of BT have been responsible for 17 percent and 25 percent of their respective gains in recent years. Among other variables, divestiture appears to have initially depressed AT&T's productivity growth, and competition for BT is too insignificant to yet have an impact. 相似文献

Engineering economics courses and textbooks have typically acknowledged the existence of the role of risk in economic decision making, but often in a peripheral way. The approach has been to suggest the existence of risk and uncertainty in engineering decisions, and to quantify that risk. The world of financial decision making includes many more powerful tools and techniques for risk management, rather than just risk measurement. The techniques of risk management include diversification, hedging, insuring, the capital asset pricing model (CAPM), futures contracts, options, and other investments. These portfolio tools are useful to engineering decision making, and the engineering economics community would be well served to include these topics in engineering economics undergraduate education. 相似文献
