Which Option Represents Equilibrium As It Appears On This Graph?

In economics, equilibrium is a state of balance where the forces of supply and demand are equal. This means that the quantity of a good or service that producers are willing to sell is equal to the quantity that consumers are willing to buy.

In a graph of supply and demand, equilibrium is represented by the point where the supply curve and the demand curve intersect. This point shows the price and quantity at which the market will clear, meaning that there will be no excess supply or demand.

In the graph above, the equilibrium point is at the intersection of the supply curve (S) and the demand curve (D). This point shows that the equilibrium price is $10 and the equilibrium quantity is 100 units.

Factors That Affect Equilibrium

The equilibrium point can be affected by a number of factors, including:

  • Changes in supply: If the supply of a good or service increases, the supply curve will shift to the right. This will cause the equilibrium price to fall and the equilibrium quantity to increase.
  • Changes in demand: If the demand for a good or service increases, the demand curve will shift to the right. This will cause the equilibrium price to rise and the equilibrium quantity to increase.
  • Government intervention: The government can also affect equilibrium by setting price ceilings or price floors. A price ceiling is a maximum price that can be charged for a good or service. A price floor is a minimum price that can be charged for a good or service.

Importance of Equilibrium

Equilibrium is important because it helps to ensure that markets are efficient. In an efficient market, the prices of goods and services are set at a level that reflects their true value. This helps to ensure that resources are allocated efficiently and that consumers are getting the best possible value for their money.

Common Mistakes to Avoid

When analyzing a supply and demand graph, it is important to avoid the following common mistakes:

  • Assuming that equilibrium is always a good thing. Equilibrium is not always desirable. In some cases, it may be better to have a market that is not in equilibrium, such as when there is a shortage of a good or service.
  • Confusing equilibrium with a fixed price. The equilibrium price is not a fixed price. It can change in response to changes in supply and demand.
  • Ignoring the role of government. The government can play a significant role in affecting equilibrium by setting price ceilings or price floors.

FAQs

1. What is the difference between equilibrium and a fixed price?

Equilibrium is a state of balance where the forces of supply and demand are equal. A fixed price is a price that is set by the government or another authority.
