In the original publication of the article, in the Tables 1–3 the font sizes are incorrect for few expressions.

In Tables 6 and 7, the expressions that were supposed to be in a single line were incorrectly provided in two lines.

And in Table 7, the signs for few parameter estimates are incorrectly provided.

Finally, the issue information was missed in the reference “Kutlu L, Tran KC, Tsionas MG (2020) A spatial stochastic frontier model with endogenous frontier and environmental variables. Eur J Oper Res (Forthcoming)”. The correct reference is “Kutlu L, Tran KC, Tsionas MG (2020) A spatial stochastic frontier model with endogenous frontier and environmental variables. Eur J Oper Res, Volume 286, Pages, 389–399”.

The original article has been corrected.
