6.2.3—Arguments for/against protectionism

Arguments for protection include infant-industry support, prevention of dumping, strategic supply security, employment and government revenue. Arguments against include higher prices, less choice, deadweight loss, retaliation and weaker competitive pressure.

Whether a protection measure works depends on time horizon, market power, elasticity, enforcement and whether the protected industry actually becomes productive. A temporary, targeted measure is not equivalent to permanent shelter.

A new industry may learn behind a time-limited tariff, but if firms lobby to keep it after productivity fails to improve, consumers continue paying more and resources remain misallocated.

“Protecting jobs” does not count only jobs saved: include jobs lost elsewhere, consumer costs, retaliation and the opportunity cost of public support.
