Study Notes
David Ricardo's Comparative Advantage and Trade Models
- David Ricardo's comparative advantage theory is based on a 2x2x1 model with 2 countries and 2 goods, assuming fixed opportunity cost, no transportation costs, and technology determining labor productivity.
- The production possibilities frontier for the home country shows that it can produce 2 units of cloth and 4 units of wheat per worker.
- In autarky, the home country's consumption of goods and wage levels are determined by perfect competition, with the relative price of wheat being the slope of the PPF.
- Opening up to trade leads to each country exporting the good in which it has a comparative advantage, changing relative prices and consumption patterns.
- The specific factors model, a 2x2x3 model, assumes 2 countries, 2 goods, and 3 factors of production, with diminishing returns to labor and technology determining labor productivity.
- Opening up to trade in the specific factors model results in overall gains from trade, but not all factors of production benefit, and the effect on labor is unclear.
- The H-O model is based on a 2x2x2 model with 2 factors of production and 2 goods, assuming constant returns to scale and relative factor endowments determining comparative advantage.
- Both the specific factors model and the H-O model show that the gains from trade are positive, but not everyone is better off, and the impact on factors of production can vary.
- The H-O model highlights that relative factor endowments determine comparative advantage, and factors of production cannot move across countries but can move between industries.
- The history of trade models suggests that each country should specialize in producing and exporting the good in which it has a comparative advantage, leading to overall gains from trade.
- The Stolper-Samuelson theorem dictates that changes in relative prices affect the returns to specific factors of production, and the effect on labor depends on consumption mix.
- In the H-O model, technology, relative factor endowments, and constant returns to scale play a key role in determining comparative advantage and the gains from trade.
International Trade: Models, Comparative Advantage, and Intra-Industry Trade
- The Heckser-Ohlin (H-O) model explains that countries specialize in goods based on the abundance of factors of production.
- Opening up to trade under the H-O model leads to a "trade triangle," benefiting both countries.
- Comparative advantage in the H-O model is determined by lower opportunity cost, not just lower absolute cost.
- The revealed comparative advantage (RCA) index measures a country's relative advantage in specific industries based on trade flows.
- Economies of scale lead to large-scale production, reducing average costs and increasing trade efficiency.
- The gravity model explains that nations trade because it is mutually beneficial and allows for efficient resource utilization.
- Intra-industry trade involves the exchange of similar products across borders, challenging traditional trade theories.
- The Grubel – Lloyd index measures intra-industry trade, with higher values indicating greater trade importance.
- The weight of intra-industrial trade is higher in developed countries and those with regional agreements.
- Intra-industrial trade has macro effects, including a greater relationship between exports and imports, and increased sensitivity to economic cycles.
- Intra-industrial trade also causes economic shocks to be transmitted more quickly across countries.
- Intra-industrial trade is important in sophisticated sectors like chemicals, electronics, and transportation equipment, and is influenced by FDI and multinational companies.
Protectionism and Trade Policy Instruments
- Protectionism exists due to the redistributive effects of free trade, creating opposition and the need for protectionist measures.
- Openness to trade generates positive net benefits, including efficiency gains, competition, and access to capital and technology.
- The adjustment process must be facilitated in areas with negative cost/benefit ratios through a flexible economy and appropriate safety nets.
- Traditional trade policy instruments include tariffs, quotas, and voluntary export restraints (VERs).
- Tariffs can be specific (fixed charge per unit) or ad valorem (fraction of value), with compound duties combining both.
- The welfare effects of tariffs result in domestic producers benefitting, consumers suffering, and the government gaining revenue.
- Import quotas restrict the quantity of imported goods and do not generate revenue for the government.
- Voluntary export restraints (VERs) are limits imposed by exporting countries, usually at the request of importing countries.
- Other protectionist instruments include domestic content requirements, red tape, and public procurement requirements.
- The World Trade Organization (WTO) was established in 1995 and builds on the rules developed since 1948 in the GATT.
- The WTO serves as a negotiating forum, a body of rules, and a dispute resolution system for international trade.
- The principles of the multilateral system include non-discriminatory treatment, promotion of free trade, and encouragement of fair competition and development.
