Measuring technical efficiency and total factor productivity change with undesirable outputs in Stata

In this article, we introduce two community-contributed data envelopment analysis commands for measuring technical efficiency and productivity change in Stata. Over the last decades, an important theoretical progression of analysis, a nonparametric method widely used to assess performance decision-making units, is incorporation undesirable outputs. Models able deal with outputs have been developed applied empirical studies assessing sustainability units. These models are getting more attention from researchers managers. The teddf command discussed present article allows users measure efficiency, both radial nonradial, when some undesirable. Technical measures obtained by solving linear programming problems. gtfpch also describe here provides tools change, example, Malmquist–Luenberger index Luenberger indicator. We provide brief overview measurement accounting outputs, syntax options new commands. illustrate examples how perform newly introduced
