Factor endownments, heterogeneous labor and North-South migration
1985
Dunlevy, J.A.
Extract: The purpose of the present paper is to make explicity a sufficient set of conditions that will support a factor endownment based migration model and to evaluate the advantages and weaknesses of that model. The resultant model is consistent both with the standard human capital model of migration and with the more mechanical gravity model; it is also consistent with the Heckscher-Ohlin model of interregional trade. The sufficient assumptions impose stringent, but not unreasonable, restrictions on the form of the underlying production function. The model's predictions are tested using a data set similar to those used in the above-noted studies. The model, however, is capable of yielding only qualitative, rather than quantitative, predictions. Therefore, there is some concern regarding the empirical identifiability of the model.
