Modelling the Determinants of Trans-Tasman Migration after World War II.

This paper identifies the economic and demographic factors responsible for migration flows between Australia and New Zealand by means of a probabilistic model of emigration in both directions. The cost of migration (proxied by t he real cost of air travel), labor market conditions, and the potenti al earnings differential play a role, although the results are modifi ed by the incidence of return migration and age composition.
