Elasticity of Demand

Perfect Competition
A market structure characterized by many firms, identical products, and free entry and exit.
What is the primary objective of firms in a competitive market?

Production Possibility Frontier (PPF)

What is the role of price in a market economy?

Price Elasticity of Supply
The responsiveness of the quantity supplied of a good to a change in its price.
Complementary Goods
Goods that are often used together, where an increase in the price of one decreases the demand for the other.
Substitute Goods
Goods that can replace each other, where an increase in the price of one increases the demand for the other.
What is the impact of a binding price floor?
It can lead to a surplus, as the price is set above the equilibrium, causing quantity supplied to exceed quantity demanded.
Income Elasticity of Demand
A measure of how much the quantity demanded of a good changes in response to a change in consumer income.
What is a public good?
A good that is non-excludable and non-rivalrous, meaning one person's consumption does not reduce its availability to others.
Economic Profit
The difference between total revenue and total costs, including both explicit and implicit costs.
