Abstract

Se presentan los pasos a seguir para la evaluación de nuevos proyectos cuando no existen activos financieros gemelos y la información es ambigua, complementando el modelo binomial probabilístico con su versión binomial borrosa. El trabajo se estructura de la siguiente manera: (a) se reseñan los modelos de valuación de opciones reales y se clasifican en probabilísticos y borrosos; (b) se desarrolla el enfoque borroso binomial de valoración con: el método MAD (Marketed Asset Disclaimer), rejillas binomiales borrosas y la aversión al riesgo del agente con el índice pesimismo-optimismo; (c) el modelo se ilustra con la valuación de un contrato de concesión de explotación petrolera con opciones de expansión-abandono-continuar, donde se comparan los resultados obtenidos entre la valoración borrosa y el modelo binomial probabilístico. Se demuestra la importancia de conjugar la valuación probabilística y borrosa en situaciones de falta de información (ambigüedad) para nuevos proyectos o empresas cerradas en mercados emergentes. / This paper presents the steps for evaluating new projects, when twin financial assets do not exist and the information is ambiguous, by complementing the binomial probabilistic model with the fuzzy binomial valuation approach. This paper is structured as follows: (a) The real option valuation models are reviewed and classified in probabilistic and fuzzy; (b) The fuzzy binomial valuation approach is developed considering the MAD (Marketed Asset Disclaimer) method, fuzzy binomial lattices and the agent´s risk aversion with the optimistic-pessimistic index; (c) The behavior of the model is illustrated using an oil extraction concession contract valuation, which has the option to expand, abandon or continue the project. The results obtained with the fuzzy valuation and the probabilistic binomial models are compared. The importance of combining the probabilistic and fuzzy valuation where there is a lack of information (ambiguity) for new project o closed firms in emerging markets is demonstrated.
