Implicit functional relationships between systematic effects in a general model of movement

In this paper some further remarks are formulated on a general systems model of movement developed by Alonso. In particular, implicit relations between systemic variables are derived, which results in the proportionality of all systems push and pull effects and the choice of a reference unit as numeraire. This results in a simplified reduced form equation. The approach is illustrated empirically using data on interprovincial migration in Canada.
