www.bauer.uh.edu- When βi = 0, we have the constant mean return model. - The MM improves over the constant mean return model: we remove from ξi,t changes related to the return on the market portfolio. - The benefit of using the MM depends on the R2 of the regression. (The higher the R2, the greater the power to detect abnormal performance.)

www.stata.comUsing a bit of algebra, we can rewrite (3) and (4) as y t = z t 1 + 1t (5) x t = z t 1 + 2t (6) where = (1 ˆ)=( ), z t = y t+ x t, and 1t and 2t are distinct, stationary, linear combinations of ˘ t and t. This representation is known as the vector error-correction model (VECM). One can think of z t = 0 as being the point at which y t and x t ...
