Suppose you are given the following panel data model Uit ~ Yit = Bo + Bixlit + B2X2it + B3Q; + Wit, i = 1, ..., N, iid (0, 02), t= 1, ..., T. Show that first differencing will introduce negative autocorrelation into the (differenced) error term with correlation coefficient p= -0.5. Find the degree of autocorrelation induced by within-groups estimation of this model.
