The arguments for restricting trade Suppose there is a policy debate regarding the United States’ imposing trade restrictions on imported ball bearings.
Read the following scenario and answer the question that follows:
A senator from a state with several ball-bearing factories argues that the government should impose a tariff on ball bearings because they are a necessary input into the production of various weapons. Free trade, she contends, would make the United States overly dependent on foreign countries for the supply of ball bearings and thus, in case of war, unable to make enough weapons to defend itself.

Which of the following justifications is the senator using to argue for the trade restriction on ball bearings?

a) Jobs argument
b) National-security argument
c) Using-protection-as-a-bargaining-ch ip argument
d) Infant-industry argument
e) Unfair-competition argument
