The hegemony of the neoclassical model as a conceptual and analytical framework to explain the operating logics of capitalism has made the ethics that this model carries implicit – the criteria, behaviours of the actors, etc., which are considered better or more appropriate due to the supposed good functioning of the system – have also occurred hegemonically. One of these “ethical” criteria or behaviors is the so-called stockholder theory, whereby a company’s sole responsibility is to increase profits for shareholders. In this article, we question the compatibility between this theory’s validity – as the empirical analysis indicates – with the social demand for companies to act with other ethics, and also how it is more plausible to move towards this change of values.
