In this paper, we link Joseph de la Vega’s work Confusion de Confusiones, written in 1688, with current behavioral finance and propose that Vega be considered the first precursor of modern behavioral finance. In addition to describing excessive trading, overreaction and underreaction, and the disposition effect, Vega vividly portrays how investors behaved three hundred years ago and includes interesting documentation on investor biases, such as herding, overconfidence and regret aversion.
