Vicente Liern, Professor of Finance and Accounting at the University of Valencia, proposes a new model based on fuzzy logic for defining and implementing the concept of social responsibility linked to the company. Liern developed this proposal in his inaugural speech as Full Academician at Real Academia de Ciencias Económicas y Financieras of Spain (RACEF), who read yerterday in Barcelona.

To Liern, the definition of corporate social responsibility is ambiguous and debtor of the historical, social and cultural situation, hence the new Academic propose in "El impacto positivo como criterio para avanzar en la inversión socialmente responsable" (The positive impact as a criterion to advance in socially responsible investing) a model to evaluate that with scientific criteria. "Try a formalization of the idea of ​​social responsibility, or actions that cause positive impact on society, using only own a deterministic mathematical models, it is inappropriate -considers Liern-. Only properly analyzing causes and effects, when we can concentrate our efforts to develop activities for the benefit of the community, we will achieve the goal". The new Academic proposes calculate degrees of impact of efficiency and social responsibility, once defined its parameters, to establish policy and business strategies.
