IBonomicsFree Trade – Exporting Country
This diagram shows how a country exports goods under free trade when the world price is higher than the domestic equilibrium price.
dd
Dd: Domestic demand for the good (e.g., chips).
sd
Sd: Domestic supply of the good.
wp
Wp: World price, higher than the domestic equilibrium price.
qd
Qd: Quantity demanded at the world price.
qs
Qs: Quantity supplied at the world price.
exports
Exports: The surplus of production (Qs − Qd) that is sold to foreign buyers.
In the absence of trade, the domestic equilibrium occurs where domestic supply (Sd) intersects domestic demand (Dd).
When the world price (Wp) is above the domestic equilibrium price, domestic producers are willing to supply more (Qs), while domestic consumers demand less (Qd).
The surplus of goods, represented by the difference between Qs and Qd, is exported to the rest of the world.
This benefits domestic producers who receive higher prices and increase production, but may harm domestic consumers who face higher prices and buy less.
Overall, the country specializes in the good it has a comparative advantage in, increasing global efficiency and welfare under free trade.

This diagram illustrates how a country imports goods under free trade when the world price is lower than the domestic equilibrium price.
This diagram shows the effects of a tariff imposed on imported goods. A tariff raises the price of imports, protecting domestic producers but creating welfare losses.
This diagram illustrates the effects of an import quota, a trade protection measure that limits the quantity of a good that can be imported. Quotas raise domestic prices, benefit local producers, and reduce consumer surplus.
This diagram illustrates the effects of a production subsidy, where the government supports domestic producers to lower their costs and increase output. It is a form of protectionism without raising consumer prices directly.
This diagram shows how an export subsidy raises the domestic price above the world price, encouraging producers to export more while reducing consumer welfare and creating deadweight losses.
This diagram uses production possibility curves (PPCs) for two countries—Grania and Chipia—to illustrate absolute and comparative advantage and the potential gains from trade.
