DEA efficiency analysis: Efficient and anti-efficient frontier

摘要

Data envelopment analysis (DEA) is a methodology for identifying the efficient frontier of production possibility set. Using this efficient frontier, an efficiency score is derived to each decision making units. This study, proposes an alternative efficiency measure by using efficient and anti-efficient frontiers. Numerical experiments show the validity of the proposed efficiency measure and its compatibility with other measures of efficiency. The paper addresses the super-efficiency issue by using this measure.
