New Efficiency Theory

This monograph develops and generalizes the new efficiency theory by highlighting the interface between economic theory and operations research. Some of the outstanding features of this monograph are: (1) integrating the theory of firm efficiency and industry equilibrium, (2) emphasizing growth efficiency in a dynamic setting, (3) incorporating uncertainty of market demand and prices, and (4) the implications of group efficiency by sharing investments. Applications discuss in some detail the growth and decline of US computer industry, and the relative performance of mutual fund portfolios.

Analyses economic efficiency and methods of improving it by using and generalizing the new management science technique called data envelopment analysis Discusses real life applications in the US computer industry
