Questions and Answers

What role do buyers play in a market?

Buyers determine the demand for a particular good or service.

In a perfectly competitive market, how do buyers and sellers interact with the market price?

What distinguishes a monopoly from other market structures?

A monopoly is characterized by a single seller who sets the price for the good or service.

In an oligopoly, what is a common strategy used by firms to compete?

Study Notes

Law of Supply

Quantity supplied increases with the good's price rise; movement occurs along the supply curve—no shift in the curve.
Factors that can shift the supply curve include:
- Input prices: Higher costs reduce supply.
- Technology: Advances can enhance efficiency, increasing supply.
- Expectations: Anticipations about future prices can affect current supply.
- Number of sellers: More sellers typically increase market supply.

Equilibrium

Achieved when market price aligns quantity supplied with quantity demanded.
Surplus occurs when quantity supplied exceeds quantity demanded.
Shortage arises when quantity demanded exceeds quantity supplied.

Law of Supply and Demand

States that price adjustments are made to balance quantity supplied and quantity demanded.
Steps for analyzing changes in equilibrium:
- Identify if event impacts supply or demand, or both.
- Determine the direction of curve shifts.
- Use supply-and-demand diagrams to assess changes in equilibrium price and quantity.

Shifts in Supply

Increase in supply with constant demand: Price falls, quantity increases.
Decrease in supply with constant demand: Price rises, quantity decreases.

Shifts in Demand

Increase in demand with constant supply: Both price and quantity increase.
Decrease in demand with constant supply: Both price and quantity decrease.
Both increase in demand and supply: Quantity increases, price uncertainty remains.
Both decrease in demand and supply: Quantity decreases, price uncertainty remains.

Utility

Utility measures satisfaction, expressed in "utils."
Differentiation is key in attracting diverse customer groups despite similar core services (e.g., hotels, fast food).

Demand

Represents the quantity of a good buyers are willing and able to purchase at various prices.
Law of Demand states quantity demanded falls as price rises, causing movement along the curve.
Factors that can shift the demand curve include:
- Consumer income: Normal goods have positive relationship; inferior goods have negative relationship.
- Price of related goods:
  - Substitutes: Higher price of one increases demand for the other (e.g., Coke and Pepsi).
  - Complements: Higher price of one decreases demand for the other (e.g., computers and software).

Supply

Reflects the quantity sellers are willing and able to sell at various prices.
Markets consist of buyers (determining demand) and sellers (determining supply).

Types of Markets

Perfectly Competitive Market: Identical goods, many buyers and sellers, no single entity influences prices; examples include the corn market.
Monopoly Market: Single seller controls pricing; examples include cable TV providers.
Oligopoly Market: Few sellers with less aggressive competition; the airline industry exemplifies this structure.
Monopolistic Competition Market: Many sellers with slightly differentiated products, allowing individual price setting; examples include hotels and hospitality services.
