Wait, did economists think at one point that the distribution of movements in a stock market followed a Gaussian pattern? I mean, amateur statisticians approximate things to Gaussian distributions all the time to make the math easier, but that's hardly a problem unique to economics.
As to the Omori distribution, have they actually succeeded in making forward looking predictions with it, or were they just fitting a model to past data? Even if it is a real phenomenon, I can think of a way to extract money from the market by making it go away off the top of my head, so I don't imagine it will last long now that it's been reported in public.
The parts about equilibrium models being taken too seriously are well taken, though.
