Given a general squared matrix M (λ) with a parameter dependence, we can find its eigenvalues and eigenvectors at second order in λ taking the following steps: • Expand the matrix M (λ) in λ up to the second power; M (λ) = M0 + λM1 + λ2M2 + O(λ3) . (A.9) •...

(and time series) models cannot explain a number of important features common to much financial data - leptokurtosis - volatility clustering or volatility pooling - leverage effects • Our “traditional” structural model could be something like: y t = 1 + 2 x 2t + ... + k x kt + u...
