Abstract

El presente trabajo utiliza el enfoque bayesiano de aprendizaje para medir la cantidad de información que un individuo gana sobre su función de utilidad después de consumir una cantidad inicial de algún bien genérico. Para ello, se desarrolla un modelo de aprendizaje bayesiano sobre los parámetros que determinan las preferencias de un individuo racional. En este marco, la información de Fisher (1950) se utiliza como una medida de la cantidad de información que contienen los parámetros del índice de satisfacción del agente después de que éste ha iniciado su consumo. A partir de la información de Fisher se construye la distribución a priori de los parámetros siguiendo la regla de Jeffreys (1961), lo cual permite tratar a la información como una variable./ This paper uses a Bayesian learning model to measure the amount of information that an individual gains on his/her utility function after consuming an initial amount of a generic good. To do so, a learning model on the parameters determining the preferences of a rational individual is developed. In this framework, Fisher’s information (1950) is used to measure the amount of information contained in the parameters of the agent’s satisfaction index once consumption has started. By using Fisher’s information and Jeffreys’ rule (1961) a priori distribution on the parameters is constructed, which allows to treat information as a variable.
