New efficiency theory refers to the various parametric and semi-parametric methods of estimating production and cost frontiers, which include data envelopment analysis (DEA) with its diverse applications in management science and operations research. 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 the US computer industry, and the relative performance of mutual fund portfolios.

From the reviews:

"The book summarizes the author’s research on efficiency theory. It emphasizes new approaches to efficiency theory emerging since the proposition of data development analysis. The text focuses on extensions of nonparametric efficiency measurement models in the following areas: cost oriented DEA models; consideration of interdependence of firms; informational basis of input-output and cost data; role of uncertainty and risk. ... The book is concisely written and of interest for readers with a background in economic theory and DEA." (Matthias Ehrgott, Zentralblatt MATH, Vol. 1048, 2004)
