A government could engage in five forms of protectionism to discourage imports: 1) Import tariffs, which increase the cost of foreign goods to protect domestic competitors; 2) Regulations, such as health or safety standards, that make it difficult for foreign companies to comply; 3) Import quotas, which restrict the quantity of certain goods that can be imported; 4) Subsidies for domestic industries to help them compete against imports; 5) Direct controls on foreign exchange to limit the amount of currency available to import goods.
