What is the price at which equilibrium is achieved?

Answer: Equilibrium price is a key concept in economics, reflecting the point at which the quantity of a good or service supplied equals the quantity demanded. At this price, the interests of buyers and sellers align perfectly.

Understanding Equilibrium Price

1. Definition:

  • The equilibrium price is the price at which the quantity of a good or service demanded by consumers is equal to the quantity supplied by producers. This equilibrium eliminates any excess supply (surplus) or demand (shortage).

2. Determination:

  • Supply Curve: Represents the relationship between the price of the good and the quantity supplied. Generally, an upward sloping curve because higher prices incentivize producers to supply more.
  • Demand Curve: Represents the relationship between the price of the good and the quantity demanded. Typically, a downward sloping curve because higher prices deter consumers from buying.

Finding the Equilibrium Price:

To find the equilibrium price mathematically, set the supply and demand equations equal to each other and solve for the price.

Example:

Suppose we have the following supply and demand equations:

  • Supply Function: Q_s = 2P - 10
  • Demand Function: Q_d = 60 - P

Where:

  • ( Q_s ) = Quantity supplied
  • ( Q_d ) = Quantity demanded
  • ( P ) = Price

Step-by-Step Calculation:

  1. Set Quantity Supplied (Qs) equal to Quantity Demanded (Qd):
2P - 10 = 60 - P
  1. Solve for Price (P):
2P + P = 60 + 10
3P = 70
P = \frac{70}{3}
P = 23.33

Thus, in this simplified model, the equilibrium price is approximately ($23.33).

Graphical Representation:

Besides the mathematical approach, equilibrium price can also be determined graphically by plotting the supply and demand curves on a graph. The point where the curves intersect represents the equilibrium price and quantity. For instance:

  • X-axis: Represents quantity.
  • Y-axis: Represents price.
  • Intersection Point: Represents the equilibrium price (P) and equilibrium quantity (Q).

Market Adjustments at Equilibrium:

  1. Surplus: If the market price is above the equilibrium price, a surplus occurs. Producers are willing to sell more than consumers are willing to buy, leading to downward pressure on price.

  2. Shortage: If the market price is below the equilibrium price, a shortage arises. Consumers want to buy more than producers are willing to sell, pushing the price upwards.

By understanding and calculating the equilibrium price, markets can effectively balance supply and demand, ensuring efficient resource allocation.
