Disequilibrium Condition

  • If price is below Rs.16 per kg, Quantity Demanded > Quantity Supplied. This condition is called Excess Demand. The price of tomatoes will rise till it reaches equilibrium price.

  • If price is above Rs.16 per kg, Quantity Demanded < Quantity Supplied. This condition is called Excess Supply. The price of tomatoes will fall till it reaches equilibrium price.

  • If Demand decreases (D1), equilibrium price and equilibrium quantity will decrease.

  • If Demand Increases (D2), equilibrium price and equilibrium quantity will increase.

  • If Supply decreases (S1), equilibrium price will increase and equilibrium quantity will decrease.
