Enumeration algorithms for FDH directional distance functions under different returns to scale assumptions

Linear programming solutions and distance functions under a constant returns to scale technology

A study on directional returns to scale

This study investigates the directional return to scale of biological institutions in the China Science Academy. In the first stage, the input-output indicators provided including staff, budget of studies, SCI articles, high quality articles and graduate education, etc. In the second stage, the method proposed by Yang (2012) was used to analyse directional return to scale and directional conges...

Using Directional Distance Functions to Determine Ranking Ranges in Cross-efficiency Evaluations

An input-oriented radial measure for returns to scale aggregation.

In production theory, it is necessary to be capable of predicting the production func- tion’s long-run behaviors. Hereof, returns to scale is a helpful concept. Returns to scale describes the reaction of a production function to the proportionally scaling all its input variables. In this regard, Data envelopment analysis (DEA) provides a com- prehensive framework for returns to scale evaluation...
