GENERAL KNOWLEDGE

Detailed explanation-1: -free trade, also called laissez-faire, a policy by which a government does not discriminate against imports or interfere with exports by applying tariffs (to imports) or subsidies (to exports).

Detailed explanation-2: -The most direct barrier to trade is an embargo– a blockade or political agreement that limits a foreign country’s ability to export or import. Embargoes still exist, but they are difficult to enforce and are not common except in situations of war.

Detailed explanation-3: -These include specific tariffs, ad valorem tariffs, compound tariffs, tariff-rate quotas, and retaliatory tariffs. A specific tariff is a tax imposed directly onto one imported good and does not depend on the value of that imported good.
