Answer 2

The most common barrier to trade is a tariff—a tax on imports. Tariffs raise the price of imported goods relative to domestic goods (goods produced at home). Another common barrier to trade is a government subsidy to a particular domestic industry. Subsidiesmake those goods cheaper to produce than in foreign markets.
