Final answer:
The intersection of import demand curve and export supply curve represents international equilibrium.
Step-by-step explanation:
The intersection of one nation's import demand curve and another nation's export supply curve represents international equilibrium.
In economics, equilibrium refers to a state where the quantity demanded by consumers is equal to the quantity supplied by producers at a specific price level. When the import demand curve of one nation intersects with the export supply curve of another nation, it indicates a balance in trade between the two countries. This represents international equilibrium where the quantity of goods and services imported by one nation matches the quantity of goods and services exported by the other nation.
For example, if Country A's import demand for cars intersects with Country B's export supply of cars, it signifies that the amount of cars Country A wants to buy from Country B matches the amount of cars Country B wants to sell to Country A. This represents an equilibrium in international trade for cars between the two countries.
