Description
Summary:•The ‘profit-Luenberger’ productivity indicator introduced by Juo et al. [6] appears to be identically equal to an empirical, profit-based Bennet quantity indicator.•Their ‘price effect’ is a residual without independent interpretation. This paper is a comment on [6]. It is shown that: (1) their ‘profit-Luenberger’ productivity indicator (πL) appears to be identically equal to an empirical, profit-based Bennet quantity indicator, and (2) their ‘price effect’ (PE) is a residual without independent interpretation.
