This paper was published in 1963, a decade before Black-Scholes. Taleb was just 3 years old. I quote:?? the stable Paretian model may be considered as predicting the occurance of phenomena likely to force the market to close. In a Gaussian model such large changes are so extremely unlikely that the occasional closure of markets must be explained by non-stochastic considerations.?
