This note considers the effect of a class of linear inter-equation constraints in the specification of the lag structure in econometric models. In particular, attention is focused on the linear summing, or "adding up�, constraints which arise between equations in factor shares analysis. The...

The Rational Distributed Lag Structural Form (RSF) representation of an econometric model is introduced and its relationship to several standard forms of representation is discussed. The FIML estimation problem for the RSF is then considered and formulated as a nonlinear, unconstrained...

The Rational Distributed Lag Structural Form of an econometric model is introduced, and its relationship to several traditional forms of representation is discussed. The traditional forms are viewed as special cases of the Rational Structural Form. Thus, the latter provides a unified framework...
