"Trade is, in some ways, a form of technology. When a country exports wheat and imports textiles, it is as if it had invented a form of technology for turning wheat into textiles. A country that eliminates trade restrictions will, therefore, experience the same kind of economic growth that would occur after a major technological advance."
