Market Equilibrium Concepts

Market Equilibrium

• Definition: Market equilibrium occurs when the quantity of a good or service supplied equals the quantity demanded at a particular price.

• Equilibrium Price (P_e): The price at which the quantity supplied equals the quantity demanded. It balances the market.

• Equilibrium Quantity (Q_e): The amount of the good or service that is both supplied and demanded at the equilibrium price.

• Graphical Representation:

  • Demand Curve: Downward sloping, reflecting that as price decreases, quantity demanded increases.
  • Supply Curve: Upward sloping, indicating that as price increases, quantity supplied also increases.
  • Equilibrium Point: The intersection of the demand and supply curves.

• Shifts in Curves:

  • Demand Shift:
    • Increase in demand shifts the demand curve right, leading to a higher equilibrium price and quantity.
    • Decrease in demand shifts the demand curve left, resulting in a lower equilibrium price and quantity.
  • Supply Shift:
    • Increase in supply shifts the supply curve right, leading to a lower equilibrium price and a higher quantity.
    • Decrease in supply shifts the supply curve left, resulting in a higher equilibrium price and lower quantity.

• Market Dynamics:

  • Surplus: Occurs when quantity supplied exceeds quantity demanded at a given price, causing pressure on prices to decrease.
  • Shortage: Occurs when quantity demanded exceeds quantity supplied at a given price, prompting prices to rise.

• Factors Influencing Equilibrium:

  • Changes in consumer preferences or income.
  • Costs of production or technology changes affecting suppliers.
  • External factors like government policies, taxes, or subsidies.

• Importance:

  • Indicates efficiency in resource allocation.
  • Helps businesses and consumers make informed decisions.
  • Essential for understanding market behaviors and trends.

Market Equilibrium

• Occurs when the quantity of a good or service supplied is equal to the quantity demanded at a specific price
• Equilibrium price (P_e) is the price at which supply and demand balance
• Equilibrium quantity (Q_e) is the amount of the good or service both supplied and demanded at the equilibrium price
• Represented graphically by the intersection of the demand and supply curves. The demand curve is downward sloping, reflecting an increase in quantity demanded as price decreases, while the supply curve is upward sloping, indicating an increase in quantity supplied as price increases.
• Changes in demand or supply shift the respective curves.
  • An increase in demand shifts the demand curve to the right, leading to a higher equilibrium price and quantity.
  • A decrease in demand shifts the demand curve to the left, leading to a lower equilibrium price and quantity.
  • An increase in supply shifts the supply curve to the right, leading to a lower equilibrium price and a higher quantity.
  • A decrease in supply shifts the supply curve to the left, leading to a higher equilibrium price and a lower quantity.
• Market Dynamics
  • Surplus occurs when quantity supplied exceeds quantity demanded at a given price leading to price reductions
  • Shortage occurs when quantity demanded exceeds quantity supplied at a given price leading to price increases.
• Factors Influencing Equilibrium:
  • Changes in consumer preferences or income.
  • Costs of production or technology changes affecting suppliers.
  • External factors like government policies, taxes, or subsidies.
• Importance
  • Indicates efficient allocation of available resources.
  • Helps businesses and consumers make informed decisions.
  • Important for understanding market behaviors and trends.
