3.4 Price Ceilings and Price Floors

Price controls are government-imposed restrictions on the prices that can be charged for goods and services. They are typically implemented to influence the availability and affordability of essential commodities or to address market failures.

Market Equilibrium: The point where the quantity supplied and the quantity demanded are equal, resulting in a stable market price.

Supply and demand is a fundamental economic concept that describes the relationship between the quantity of a good or service supplied by producers and the quantity demanded by consumers. It is a critical principle that underpins the functioning of markets and the determination of prices across various industries and sectors.

Equilibrium Price: The price at which the quantity supplied and the quantity demanded are equal, representing a stable market condition.

Elasticity: The responsiveness of supply or demand to changes in price or other factors, which can influence the impact of supply and demand on market outcomes.

Market Clearing: The process by which the quantity supplied and the quantity demanded are equal, resulting in the market reaching an equilibrium state.
