In particular, attention is focused on the linear summing, or "adding up�, constraints which arise between equations in factor shares analysis. The consequences of such constraints on the specification of lag structures for models with dynamic adjustments and autoregressive or moving-average disturbances are presented in the form of linear restrictions which result in singular coefficient matrices . Thus, the structural (lag) specification of one equation depends on the structure of all other equations in the model UR - https://www.nber.org/papers/w0119 UR - http://dx.doi.org/10.3386/w0119 ER -
