Abstract
This research aims at analyzing the impact that the variables of sustainable value generation (ESG) have on the efficiency of firms listed on the Mexican Stock Exchange Sustainable Index during the period 2014-2017. The non-parametric method of Data Envelopment Analysis (DEA) was used to determine their efficiency. Results indicate that, given the level of profitability, the variable that most affects the generation of sustainable value is corporate governance (G), followed by environmental (E) and social (S) practices. The main limitation of the study is the sample size. The originality of this paper lies in the fact that it determines corporate efficiency using financial performance as an input of a DEA model and sustainable value ratings as outputs. Conclusions show that corporate social responsibility activities may enhance firms’ sustainable efficiency. Therefore, it is proposed that corporate efficiency might be complemented by sustainable value measurements.
