Recently, Fagiolo et al. (2008) find fat tails in the distribution of economic growth rates after adjusting for outliers, autocorrelation, and heteroskedasticity. This paper employs US quarterly real output growth, showing that this finding of fat tails may reflect the Great Moderation. That is, leptokurtosis disappears after GARCH adjustment once we incorporate the break in the variance equation to account for the Great Moderation.
