(Consistency of clustered standard errors.) Consider the panel data model 
where all variables are scalars. Assume that Assumption #1, #2, and #4 in Key Concept 10.3 hold and strengthen Assumption #3 so that X it and u it have eight nonzero finite moments. Let M = I T T 1 , where is a T × 1 vector ones, Also let Y i = ( Y i 1 · Y i 2 … Y iT ) , X i = ( X i 1 X i 2 … X iT ) , u i = ( u i 1 u i 2 … u iT ) , 
, and 
. For the asymptotic calculations in this problem, suppose that T is fixed and n
