On the frequency of large stock returns: putting booms and busts into perspective
Numerous articles have investigated the distribution of share prices, and find that the yields are leptokurtic. There is still controversy about the amount of leptokurtosis, and hence about the most appropriate distribution to use in modeling returns. This controversy has proven hard to resole, as the alternatives are non-nested. We propose to employ extreme value theory focusing exclusively on the larger observations, in order to assess the leptokurtosis within a unified framework. This enables one to generate robust probabilities on large changes, which put the recent stock market swings ...

This paper questions the robustness and logical consistency of Marini's result. It demonstrates that Marini's claim is overturned when the length of private agents's horizons does not fall short of the length of the lags in the feedback rule, so that private agents correctly incorporate knowledge of the wealth they will receive from future transfers into their decision ...
