ABSTRACT: In this paper, we consider the redundancy
of an extra set of moment conditions, given an initial set of moment conditions,
for the efficient estimation of an arbitrary linear transformation of an
original parameter vector. The redundancy condition derived in the current
paper unifies the full and partial redundancy of moment conditions of Breusch,
Qian, Schmidt and Wyhowski (Journal of Econometrics, 1999).
