Welcome to class!
In today’s class, we will be talking about demand and supply. Enjoy the class!
DEMAND AND SUPPLY
- Change in Quantity Demanded
- Change in Demand
- Change in Quantity Supplied
- Change in Supply
- Effects of change in demand and supply on equilibrium price and quantity
CHANGE IN QUANTITY DEMANDED
A change in quantity demanded, is otherwise known as movement along a particular demand curve that is only influenced by price. When there is a change in the quantity demanded, the demand curve does not shift. This is because the price of the commodity is the only cause of a change in the quantity demanded while other factors remain unchanged.
CHANGES IN DEMAND
When different quantities of goods and services are demanded at a particular price, it is called a change in demand. It is caused by those factors that generally affect the demand of a commodity other than the price of the commodity; For example changes in taste and fashion, changes in income etc Change in demand shows a shift of the demand curve to an entirely new position. A shift of the demand curve to the right is termed an increase in demand while a shift of the demand curve to the left is a decrease in demand.
CHANGES IN QUANTITY SUPPLIED
Change in quantity supplied is only influenced by price. It involves movement along the same supply curve
EFFECTS OF CHANGES IN DEMAND AND SUPPLY ON EQUILIBRIUM PRICE AND QUANTITY
Changes in demand and supply lead to a change in the equilibrium price. Once there is any change in either demand or supply, the initial equilibrium will be disrupted and a new equilibrium will be created. The market equilibrium price can be affected in the following ways
Effects of Decrease in Supply
- Increase in the equilibrium price from P1 to P2
- A decrease in the equilibrium quantity from Q1to Q2
Decrease in demand and decrease in supply.
- Increase in demand and decrease in supply.
In our next class, we will be talking about the Elasticity of Demand. We hope you enjoyed the class.
