💵Principles of Macroeconomics Unit 20 – International Trade

Key Concepts and Definitions

• International trade involves the exchange of goods and services across national borders
• Exports are goods and services produced domestically and sold to other countries
• Imports are goods and services bought from other countries and consumed domestically
• Balance of trade measures the difference between a country's exports and imports
  • A trade surplus occurs when exports exceed imports
  • A trade deficit occurs when imports exceed exports
• Tariffs are taxes imposed on imported goods to protect domestic industries or generate revenue
• Quotas limit the quantity of a specific good that can be imported into a country
• Embargo completely prohibits trade with a particular country

Historical Context of International Trade

• Trade routes (Silk Roads) facilitated early international trade connecting Asia, Europe, and Africa
• Mercantilism, a 16th-18th century economic theory, emphasized maximizing exports and minimizing imports to accumulate wealth
• The Industrial Revolution in the late 18th and 19th centuries led to increased production and expanded international trade
• Colonialism and imperialism in the 19th and early 20th centuries shaped global trade patterns and power dynamics
  • European powers established colonies to secure raw materials and markets for their manufactured goods
• World Wars I and II disrupted international trade, leading to increased protectionism and economic nationalism
• The post-World War II era saw the establishment of international institutions (World Bank, IMF) to promote free trade and economic cooperation
• Globalization in the late 20th and early 21st centuries has increased economic interconnectedness through advances in transportation and communication technologies

Theories of International Trade

• Mercantilism advocated maximizing exports and minimizing imports to accumulate gold and silver
• Adam Smith's theory of absolute advantage suggests countries should specialize in producing goods they can make most efficiently
• David Ricardo's theory of comparative advantage proposes countries should specialize in goods they can produce at a lower opportunity cost
  • Even if a country has an absolute advantage in producing all goods, it can still benefit from specialization and trade
• Heckscher-Ohlin model emphasizes differences in factor endowments (land, labor, capital) as the basis for trade
• New trade theory accounts for the role of economies of scale, product differentiation, and imperfect competition in international trade
• Gravity model suggests trade between countries is proportional to their economic size and inversely proportional to the distance between them
• Intra-industry trade involves the exchange of similar products within the same industry between countries

Comparative and Absolute Advantage

• Absolute advantage refers to a country's ability to produce a good using fewer resources than another country
  • If Country A can produce 10 units of a good with the same resources that Country B uses to produce 5 units, Country A has an absolute advantage
• Comparative advantage considers the opportunity cost of producing a good relative to other goods
  • Opportunity cost is the value of the next best alternative forgone when making a choice
• A country has a comparative advantage in producing a good if it has a lower opportunity cost than another country
• Specialization based on comparative advantage leads to more efficient resource allocation and increased overall output
  • If each country specializes in the good it has a comparative advantage in and trades, both countries can consume more than they could without trade
• Comparative advantage is a dynamic concept that can change over time due to factors such as technological advancements or changes in resource availability

Trade Policies and Barriers

• Free trade allows for the unrestricted flow of goods and services between countries without government intervention
• Protectionism involves government policies that restrict international trade to protect domestic industries
• Tariffs are taxes imposed on imported goods, increasing their price and making them less competitive compared to domestic goods
  • Specific tariffs are fixed amounts per unit of imported goods
  • Ad valorem tariffs are percentages of the value of imported goods
• Import quotas limit the quantity of a specific good that can be imported into a country
• Voluntary export restraints (VERs) are agreements where an exporting country voluntarily limits its exports to an importing country
• Non-tariff barriers include regulations, standards, and bureaucratic procedures that can hinder trade
• Subsidies are government payments to domestic producers, allowing them to sell goods at lower prices and compete with imports
• Dumping occurs when a country exports a product at a price lower than its domestic price or production cost

Exchange Rates and Currency Markets

• Exchange rate is the price of one currency in terms of another currency
  • For example, if the exchange rate between the U.S. dollar (USD) and the euro (EUR) is 1.20, it means 1 EUR costs 1.20 USD
• Appreciation occurs when a currency increases in value relative to another currency
• Depreciation occurs when a currency decreases in value relative to another currency
• Floating exchange rates are determined by supply and demand in foreign exchange markets without government intervention
• Fixed exchange rates are set and maintained by the government through central bank intervention
• Managed float or dirty float is a hybrid system where exchange rates are allowed to fluctuate within a certain range, with occasional government intervention
• Currency devaluation is a deliberate downward adjustment of a currency's value by the government
• Currency revaluation is a deliberate upward adjustment of a currency's value by the government
• Purchasing power parity (PPP) theory suggests that exchange rates should adjust to equalize the prices of goods and services across countries

Global Trade Organizations and Agreements

• World Trade Organization (WTO) is an international organization that oversees and enforces global trade rules and resolves trade disputes
  • Promotes trade liberalization through negotiations and agreements
  • Provides a forum for member countries to discuss trade policies and issues
• General Agreement on Tariffs and Trade (GATT) was a multilateral agreement that preceded the WTO, focusing on reducing tariffs and other trade barriers
• Regional trade agreements (RTAs) are treaties between two or more countries to establish a free trade area or customs union
  • Examples include the North American Free Trade Agreement (NAFTA) and the European Union (EU)
• Bilateral trade agreements are treaties between two countries to promote trade and investment
• Preferential trade agreements (PTAs) provide preferential market access to certain countries, often based on historical or political ties
• Trade blocs are groups of countries that have agreed to reduce or eliminate trade barriers among themselves
  • Can take the form of free trade areas, customs unions, common markets, or economic unions
• Multilateral trade negotiations, such as the Doha Round, aim to further liberalize global trade through the WTO framework

Impact on Domestic and Global Economies

• International trade allows countries to specialize based on their comparative advantages, leading to increased efficiency and output
• Trade enables countries to consume a greater variety of goods and services than they could produce domestically
• Increased competition from imports can lead to lower prices and improved quality for consumers
• Trade can create jobs in export-oriented industries and sectors that benefit from foreign investment
  • However, import competition can lead to job losses in industries that are less competitive internationally
• Trade can contribute to economic growth by expanding markets, attracting foreign investment, and facilitating the transfer of technology and knowledge
• Unequal distribution of trade benefits can lead to income inequality within and between countries
  • Low-skilled workers in developed countries may face downward pressure on wages due to competition from low-wage countries
• Dependence on trade can make countries vulnerable to global economic shocks and fluctuations in commodity prices
• Trade can have environmental consequences, such as increased carbon emissions from transportation or the exploitation of natural resources
• Cultural exchange and increased understanding between countries can be facilitated by international trade
• Geopolitical tensions and conflicts can arise from trade disputes or imbalances
