In this study, we merge results of two recent directions in efficiency analysis research—the Aggregation and the Bootstrap—applied, as an example, to one of the most popular point-estimators of individual efficiency: the Data Envelopment Analysis (DEA) estimator. A natural context of the methodology developed here is a study of efficiency of a particular economic system (e.g., an industry) as a whole, or a comparison of efficiencies of distinct groups within such a system (e.g., private vs. public or regulated vs. non-regulated firms, etc). Our methodology is justified by the (neo-classical) economic theory and is supported by carefully a dapted statistical methods.
