International Trade: Theory and Practice

• Adam Smith's theory of comparative advantage: if a country can obtain a commodity cheaper from another country, it's economically beneficial to import that commodity.

• Division of labor and specialization leads to increased productivity.

• Comparative advantage depends on a country's inherent endowments and those of its trade partners.

• Factors of production: land, labor, and capital.

• Trade is mutually beneficial but is often restricted due to various reasons and actors.

• Trade restrictions include tariffs, quotas, nontariff barriers, and subsidies.

• Protectionism vs. free trade: winners and losers of international trade.

• Foreign trade hurts domestic producers, leading to protectionist policies.

• Factor-based preferences: the Heckscher-Ohlin theorem states that countries export goods made with their abundant factor, and thus prefer free trade.

• Specific factors-based preferences: when factors are tied to industries, trade affects all factors in the same way, and export industries benefit from freer trade.

• Winners and losers of free trade/protectionism: protectionism benefits domestic protected industries, while consumers, foreign producers, and domestic exporters lose.

• Compensation for the losers of free trade: some gains from trade can be used to compensate the losers, weakening their opposition to free trade.

• Export-oriented sectors want freer trade, while import-competing sectors want protectionism.

• Patterns of trade restrictions: some actors have political power over trade policy, creating a collective action problem. Policy change can be seen as a public good for a group.

• Consumers, who are the largest group, exercise less influence than producers.

• Foreign producers have limited political clout.

• Adam Smith advocates for comparative advantage, encouraging countries to specialize and trade for mutual benefit.

• Comparative advantage depends on a country's endowments and those of its trading partners.

• Factors of production include land, labor, and capital.

• Trade restrictions, such as tariffs, quotas, and subsidies, exist despite the potential negative effects on welfare and productivity.

• Wars can be costly for countries, and trade restrictions can be influenced by various actors.

• Protectionist policies can be driven by domestic preferences, particularly for countries with abundant or specific factors.

• Winners and losers of free trade include domestic producers, consumers, and foreign producers.

• Compensation for the losers of free trade can weaken their opposition and promote support for freer trade.

• Patterns of trade restrictions can be influenced by political power and policy change.

• Collective action problems and policy change can impact the implementation of trade policies.

• Consumers, as the largest group, generally have less influence on trade policies compared to producers.

• Foreign producers can have limited political clout.

• Export-oriented sectors generally favor freer trade, while import-competing sectors favor protectionism.

• The losers of free trade include consumers of imported goods, foreign producers, and domestic exporters.

• Politicians promoting protectionist policies can face backlash from citizens opposed to such policies.

• Compensation for the losers of free trade can take various forms, such as worker retraining programs and unemployment benefits.

• Some countries, particularly those with abundant land for agriculture, can be more open to trade due to their comparative advantage.
