Equilibrium Price

Equilibrium price: when the amount of supply equals the amount in demand.
  • Essentially this means that supply and demand helps determine the equilibrium price.
  • When supply exceeds demand, sellers have to lower their prices in an attempt to get buyers to purchase.
  • When demand is greater than the supply, the buyers make the price go up because they are competing to buy the same goods.
  • Factors such as the cost of production, consumption habits, and restrictive practices and monopolies help influence the equilibrium price.
    • For example, if the buyer's consumption habit changes and they begin buying more of a certain product, there will be more of a demand for it.
  • To maintain an equilibrium price, the supply would have to rise as well. If the supply did not rise, then sellers would raise the price of their goods, throwing off the equilibrium price.
