This book presents a novel technique for comparative analysis of multi-output firms. In particular it provides a statistical foundation for output-specific efficiency estimation. This is necessary to find out whether firms of an economic sector systematically produce some good A more efficiently than some good B and to quantify eventual differences. In the presence of such differences the application of existing estimation techniques is either inappropriate or does not lead to statistically meaningful results. In this sense the book fills a remaining gap in the relevant literature. The key idea behind the approach is to use posterior distributions of target output-ratios of firms to determine reference points for performance comparison purposes. Monte Carlo simulations and an application to a real world data set indicate expectable small sample performance and the practical usefulness of the presented approach. §Audience: Economists, MS/ OR researchers, and their libraries.
