Calibrating Alonso's General Theory of Movement: the Case of Inter-Provincial Migration Flows in Canada

First, it is shown that Alonso's general theory of movement relies on a standard doubly-constrained spatial interaction model which subsumes the usual gravity and entropy-derived formulations. Such a finding then suggests the use of a biproportional adjustment method (RAS method) to adequately estimate the systemic variables specified in the underlying model. This eventually leads to the development of a complete and precise methodology for calibrating the Alonso model. This methodology is illustrated with the help of an application to data on interprovincial migration in Canada.
