Webcation based on second moments vs. higher-order moments is not a choice between Gaus-sian shocks vs. non-Gaussian shocks. Second-moment SVAR estimators require neither Gaus-sianity, nor mutual shock independence, as dis-cussed in Section I. III.

Thus, the variance is the second moment of X about μ=𝔼(X), or equivalently, the second central moment of X. Second moments have a nice interpretation in physics, if we think of the distribution of X as a mass distribution in ℝ.
