Comparative Advantage
Definition: Comparative advantage is the ability of an individual, firm, or country to produce a good or service at a lower opportunity cost than others. It explains how trade can be beneficial even when one party is more efficient at producing all goods.
Example:
Country A can produce 10 units of wine or 5 units of cloth with the same resources; Country B can produce 6 units of wine or 3 units of cloth. Country A’s opportunity cost of 1 unit of cloth is 2 units of wine, while Country B’s opportunity cost is also 2 units of wine. If instead Country B could produce 6 units of wine or 4 units of cloth, B’s opportunity cost of cloth would be 1.5 units of wine, so B has comparative advantage in cloth and A in wine. They can trade to benefit both.
Demand for any good
Definition: Demand is the relationship between the price of a good and the quantity that consumers are willing and able to buy at each price, holding other factors constant. The law of demand states that, ceteris paribus, quantity demanded falls as price rises.
Example:
At a price of $2 per unit, consumers demand 100 units of coffee; at $3, they demand 80 units. A decrease in income (for an inferior good) or a rise in price of a complement will shift the demand curve.
Supply of any good
Definition: Supply is the relationship between the price of a good and the quantity that producers are willing and able to sell at each price, holding other factors constant. The law of supply states that quantity supplied tends to rise as price rises.
Example:
A farmer supplies 50 units of apples at $1 per unit and 90 units at $2 per unit. An improvement in production technology or a fall in input costs shifts the supply curve to the right, increasing quantity supplied at each price.
Opportunity Cost
Definition: Opportunity cost is the value of the next best alternative that is forgone when a choice is made. It includes explicit and implicit costs and measures trade-offs.
Example:
If you attend college instead of working a job that would pay $20,000 per year, the opportunity cost of a year in college includes the $20,000 forgone income plus tuition and other expenses.
Equilibrium price and quantity
Definition: The equilibrium price and quantity are the market-clearing price and quantity where quantity demanded equals quantity supplied. At this point there is no tendency for the price to change, absent external shocks.
Example (simple algebra):
Suppose Qd = 120 − 10P and Qs = 20 + 10P. Setting Qd = Qs gives 120 − 10P = 20 + 10P, so 100 = 20P, P = 5. Substituting back gives Q = 70. The equilibrium price is $5 and the equilibrium quantity is 70 units.
