International factor migration and the U.S.

Conclusion The model employed is sufficiently realistic to provide conclusions regarding income distribution due to factor migration. While more disaggregation and other models would be revealing, these results correspond to observed positions on migration issues. Owners of a productive factor can be expected to favor migration policy, either the making or enforcing of laws, favorable to themselves. A factor owner's sentiments can be predicted by identifying patterns of friendship. While each productive factor is its own enemy, empirical results for the U.S. identify two pairs of enemies as well: capital/skilled and semiskilled/unskilled labor. Unskilled labor is a friend of capitalists and skilled labor, both of which can be expected to favor their free immigration.
