Uncertainty and probability in Keynes. A Bayesian-type review

Este articulo analiza el concepto de probabilidad en la obra de Keynes y propone un metodo para formalizar la nocion de la incertidumbre en la Teoría general utilizando el teorema de Bayes y el principio de maxima entropia. Una de las principales conclusiones es que, a pesar de compartir su rechazo del enfoque frecuentista de la estadistica, es poco razonable pensar que no se pueden determinar probabilidades numericas, aunque se cumpla algun criterio de objetividad.This paper analyzes the concept of probability in Keynes’ work and proposes a method for formalizing the notion of uncertainty in the General Theory using Bayes’ theorem and the principle of maximum entropy. One of the main conclusions is that, despite sharing his rejection of the frequentist approach to statistics, it is unreasonable to think that numerical probabilities cannot be determined, even if some criterion of objectivity is met
