Study Notes

Demand Curve

A rise in price from P1 to P2 reduces quantity demanded from Q1 to Q2, followed by movement along the same demand curve from point A to B.

Factors Influencing Demand

Apart from the price of the goods, other factors that influence the quantity of goods consumers plan to purchase at each price include: • Tastes and preferences • Number and prices of related goods (substitutes and complements) • Income (normal goods and inferior goods) • Distribution of income • Expectations of future prices

Change in Demand

A change in any other factor apart from the price of the goods will lead to a change in demand, shifting the entire demand curve.

Consequences of a Binding Price Ceiling

A permanent shortage becomes inevitable, leading to: • Queuing and waiting • Discrimination by sellers • Rationing • Black or underground market • Worsening scarcity of commodities

Setting a Maximum Price (or Price Floor)

A price floor is the minimum price legally enforced by the government to: • Prevent prices of certain commodities from falling below a certain level • Safeguard the economic interests or incomes of producers • Create a surplus (e.g., grains, corn, or wheat) for possible future shortages

Change in Quantity Supplied

Reflected by a movement along the same supply curve.

Change in Supply

Reflected by a shift in the entire supply curve.

Market Equilibrium

The decisions of buyers and sellers interact to determine the equilibrium price and quantity.
At the equilibrium level, quantity demanded equals quantity supplied.

Market Disequilibrium

Shortages or surpluses appear in a market, and prices function as allocative mechanisms.

A Change in Demand

An increase in demand shifts the demand curve rightward, creating a market shortage, pushing up the price, and increasing quantity supplied.

A Change in Both Demand and Supply

A simultaneous increase in both demand and supply shifts both curves rightward, making the impact on equilibrium price and quantity ambiguous, depending on the relative magnitude of the change in demand and supply.
