Import the products, or the producers

by Robert Higgs

"A country’s people can foster their prosperity by participating in the extended, or international, system of specialization and exchange according to comparative advantage. If the people of country A want what the workers of country B can produce at comparatively low opportunity cost, they can get those products in two distinct ways. The first is to import freely (that is, without tariffs, quotas, or other costly obstructions) the products made by workers in country B. The second is, for some types of production, to import the workers from country B (that is, to permit unobstructed immigration) and set the migrant workers to work in domestic, country A firms. The two ways are broadly substitutes." (10/11/17)
