Chapter 9International Trade
The Determinants of Trade
• Without international trade, domestic supply & domestic demand meet at an equil. price.
• World price = price of a good that prevails in world market
• If world price < domestic price, you import;if world price > domestic price, you export
- Both based on comparative advantage
Winners and Losers from Trade
• Assumption: the country is small compared to world (price takers)
• Example of an Exporting Country
Gains & Losses from Trade
• Exporting country:1. Domestic producers are better off and
domestic consumers are worse off2. Trade raises economic well-being of a nation;
rise in total surplus
Gains & Losses of an Importing Country
• World price below domestic price leads to imports
Winners & Losers
• Importing Country:1. When importing, domestic consumers are
better off, and domestic producers are worse off
2. Trade raises economic well-being of a nation with increased total surplus
• Trade policies expands size of economic pie, but also creates winners & losers
The Effects of a Tariff
• Tariff - tax on imports• Tariff raises price of imports above the world
price (by size of tariff) and pushes it closer to price that would prevail without trade
Effects of a Tariff
• By raising price, it reduces the quantity of imports and moves the market closer to equilibrium without trade
• Domestic sellers are better off, domestic buyers are worse off
• Total surplus has fallen, creating DWL (because a tariff is a tax)
Effects of an Import Quota
• Limit on the quantity of a good that can be produced abroad and sold domestically
• Shifts supply curve to right by size of quota
