4. Countries may choose to participate in free trade agreements or groups like the World Trade Organization (WTO) to promote economic growth, increase market access, reduce trade barriers, and enhance international cooperation. By joining these agreements, countries can benefit from increased trade opportunities, attract foreign investments, and gain access to a larger market for their goods and services. Additionally, participation in these agreements can help countries to establish common rules and standards for trade, which can promote fair competition and reduce the risk of trade disputes.<br /><br />5. Implementing tariffs can impact a state's trade balance in several ways. On the one hand, tariffs can make imported goods more expensive, which can reduce the demand for imports and potentially improve the trade balance. On the other hand, tariffs can also lead to retaliatory measures from trading partners, which can reduce the demand for exports and worsen the trade balance. Furthermore, tariffs can lead to higher prices for consumers, which can reduce their purchasing power and potentially reduce overall demand in the economy.<br /><br />6. The theory of comparative advantage supports the idea of free trade agreements by suggesting that countries can benefit from specializing in the production of goods and services in which they have a comparative advantage, and then trading with other countries to obtain goods and services in which they have a comparative disadvantage. This theory suggests that even if one country is more efficient in the production of all goods compared to another country, there can still be gains from trade. By engaging in free trade, countries can specialize in the production of goods and services in which they have a comparative advantage, leading to increased efficiency, lower prices, and higher overall welfare.
