This Second Edition of AN INTRODUCTION TO EFFICIENCY AND PRODUCTIVITY ANALYSIS provides a significant revision of the popular First Edition that was published in 1998. The principle elements of the First Edition have been retained. It remains the only book that provides a comprehensive and unified introduction to the main techniques used in this field. Namely, index number methods, data envelopment analysis (DEA) and econometric techniques, including stochastic frontier analysis (SFA). For each technique the basic methods are carefully described with the aid of numerous diagrams, simple empirical examples and computer output listings. Following this the more advanced aspects of each technique are then discussed.

From the reviews of the second edition:

"The authors introduce the four major methods economists use to analyze efficiency and productivity: econometric estimation of average response, index numbers, data envelopment analysis (DEA), and stochastic frontier analysis. They intend the book primarily as a text for students in economics and also for students in other disciplines, such as business administration. ? On the whole, I rate the book as excellent ? ."
