A parameter-free approach for estimating the quality and quantity of the right and left returns to scale in Data Envelopment Analysis

作者：

Highlights：

• This paper studies the estimation of the right and left returns to scale.

• The new method detects both the type and the value of returns to scale.

• The advantage of the new method is that it uses no parameter in model formulation.

• A case study in banking system validates the new method.
