World trade benefits from free and fair trade among nations. Nevertheless, governments of many countries continue to practice protectionism. While protectionism earns profits for domestic producers and tariff revenues for governments, consumers pay higher prices because of protective restrictions. Imposing tariffs increases the price of goods to consumers. Removing tariffs decreases the price of goods to consumers. Imposing quotas limits supply and therefore increases the price of goods to consumers. Removing quotas makes products more available and therefore decreases the price of goods to consumers.
