Growth and Efficiency in Computer Industry,ice decline for personal computes has accelerated in recent years reaching nearly 28 percent per year from 1995 to 1998. Significant economies of scale and learning curve effects have often been the key to this rapid price decline.

Input Sharing and Efficiency, in the communications industry. In modem growth theory in macroeconomics Lucas (1993) and others have emphasized the scale economies at the industry level e.g., R&D investment and how it spreads through transmission of new knowledge across firms, which then enjoy productivity gains as external economies.

Modeling and Data Problems,less compelling. The need for exploring some transformations of the input Output data e.g., log transformation is likely to be useful. For example in modern high-tech industries the effects of inputs such as R&D investment and new innovation are strongly nonlinear. Hence we need to extend the DEA modeis accordingly.

New Approaches to Economic Efficiency,put vector is said to be technically efficient, if and only if increasing any output or decreasing any input is possible only by decreasing some other output or increasing some other input. Fare, Grosskopf and Lovell (1994) have surveyed this field of production frontiers and discussed the contributions of Koopmans, Debreu, Farrell and others.

Cost Oriented Efficiency, ignored or very infrequently analyzed. As a result the influence of the overall market on the cost efficiency of firms and the dynamics of entry and exit behavior of firms under varying efficiency and demand fluctuations have rarely been looked into.
