Of the arguments for limiting trade which one is the most appealing to economists

Question

Quizplus · Accepted Answer

Protecting an industry important to a nation's defense is the most appealing argument for limiting trade from an economist's perspective as it relates to national security, which is a legitimate concern for a nation. It can also be argued that national security is a public good and therefore justifies government intervention in trade policy. Other arguments such as protecting jobs or helping troubled industries may be politically popular, but they often come at a cost to the overall economy in terms of higher prices for consumers and reduced global economic integration. Protecting profits of companies is generally not a valid argument for limiting trade as it primarily benefits a specific industry or company rather than the greater economy.
