title: Econometrically accounting for identities and restrictions in models of interregional migration.
abstract: "Interregional demographic identities and other restrictions are explicitly taken into account in a simple time-series model of interregional migration.  This goal is accomplished through the imposition of adding-up constraints on the estimated coefficients of a multi-equation linear system and by testing for homogeneity and symmetry.  The pitfalls of utilizing the described procedures for migration analysis and forecasting are discussed.  Full implementation of the technique is shown to require far more time-series observations on interregional migration than are commonly available."
