There is an error in my 2004 paper "Wealth, Information Acquisition and Portfolio Choice". This note shows how to correct it by adjusting the hypotheses of the model. Specifically, it assumes that agents learn about the stock's mean payoff rather than about its realization. All the conclusions of the paper remain valid.
