Summary and Exam Tips for Benefits and Costs of International Trade
Benefits and costs of international trade is a subtopic of The Global Economy, which falls under the subject Economics in the IB DP curriculum. International trade involves the exchange of goods and services across borders, leading to globalization and economic integration. Free trade occurs without government intervention, allowing prices to be set by global demand and supply. This results in benefits such as increased competition, lower prices, greater choice, access to resources, and economies of scale. Countries engaging in free trade often see improved productivity and efficiency, along with access to technology and innovation. However, some countries may adopt protectionism to restrict trade flow. In a free trade scenario, a country may export goods if the world price is higher than the domestic price, leading to increased production and export revenue. Conversely, if the world price is lower, the country may import goods, resulting in increased domestic demand and import expenditure. Calculating exports and imports involves understanding the shifts in domestic supply and demand, and the resulting changes in consumer and producer surplus.
