How are equilibrium price and quantity affected when income of the consumers increases?

Chapter 3 Outline
II. THE EFFECTS OF CHANGES IN DEMAND AND SUPPLY ON EQUILIBRIUM PRICE AND QUANTITY
A. Change in Demand
1. A change in demand will cause equilibrium price and output to change in thesame direction.
a. A decrease in demand will cause a reduction in the equilibrium price and quantity of a good.
1. The decrease in demand causes excess supply to develop at the initial price.
a. Excess supply will cause price to fall, and as price falls producers are willing to supply less of the good, thereby decreasing output.
b. An increase in demand will cause an increase in the equilibrium price and quantity of a good.
1. The increase in demand causes excess demand to develop at the initial price.
a. Excess demand will cause the price to rise, and as price rises producers are willing to sell more, thereby increasing output.
B. Change in Supply
1. A change in supply will cause equilibrium price and output to change inopposite directions.
a. An increase in supply will cause a reduction in the equilibrium price and an inase in the equilibrium quantity of a good.
1. The increase in supply creates an excess supply at the initial price.
a. Excess supply causes the price to fall and quantity demanded to increase.
b. An dcrease in supply will cause an increase in the equilibrium price and a decrease in the equilibrium quantity of a good.
1. The decrease in supply creates an excess demand at the initial price.
a. Excess demand causes the price to rise and quantity demanded to decrease.
C. Changes in Demand and Supply
1. If demand and supply change in opposite directions, then the change in theequilibrium price can be determined, but the change in the equilibrium. output cannot.
a. A decrease in demand and an increase in supply will cause a fall in equilibrium price, but the effect on equilibrium quantity cannot be determined.
1. For any quantity, consumers now place a lower value on the good, and producers are willing to accept a lower price; therefore, price will fall. The effect on output will depend on the relative size of the two changes.
b. An increase in demand and a decrease in supply will cause an increase in equilibrium price, but the effect on equilibrium quantity cannot be detennined.
1. For any quantity, consumers now place a higher value on the good,and producers must have a higher price in order to supply the good; therefore, price will increase. The effect on output will depend on the relative size of the two changes.
2. If demand and supply change in the same direction, the change in the equilibrium output can be determined, but the change in the equilibrium price cannot.
a. If both demand and supply increase, there will be an increase in the equilibrium output, but the effect on price cannot be determined.
1. If both demand and supply increase, consumers wish to buy more and firms wish to supply more so output will increase. However, since consumers place a higher value on each unit, but producers are willing to supply each unit at a lower price, the effect on price will depend on the relative size of the two changes.
b. If both demand and supply decrease, there will be a decrease in the equilibrium output, but the effect on price cannot be determined.
1. If both demand and supply decrease, consumers wish to buy less andfirms wish to supply less, so output will fall. However, since consumers place a lower value on each unit, but producers are willing to supply each unit only at higher prices, the effect on price will depend on the relative size of the two changes.

How are equilibrium price and quantity affected when income of the consumers decrease.

Solution

Decrease in the income of consumers

How are equilibrium price and quantity affected when income of the consumers increases?

The decrease in consumers’ income is depicted by leftward parallel shift of demand curve from D1D1 to D2 D2. Consequently, at the price Pe, there will be an execs supply (qe − q1), resulting the price to fall. At the new equilibrium (E2), where D2D2 intersect the supply curve, the equilibrium price falls from Pe to P2 and the equilibrium quantity falls from qe to q2.

What happens to equilibrium price and quantity when consumer income increases?

Solution: An increase in consumers' incomes increases the demand for computers. This increases the equilibrium price and equilibrium quantity. An advance in technology increases the supply. This decreases the equilibrium price and increases the equilibrium quantity.

How are equilibrium price and quantity affected a when income of consumers decrease?

In case of normal goods income effect is positive which means with increase in income demand tends to rise whereas with decrease in income demand tends to fall. But, in case of inferior goods the income effect is negative with an increase in income the demand for inferior goods will reduce and vice versa.

How does consumer income affect equilibrium price?

It is correct because consumer income is related to production cost, and a decline in production cost will decrease the equilibrium price level of the good. A declining price of a substitute good directly affects the demand of the given good and decreases the quantity demanded by the consumers due to its high price.

What will be the effect on equilibrium price and equilibrium quantity when income increases in case of normal goods?

Explanation: Normal goods are those whose demand rises as income rises and declines as income decreases. In the case of ordinary products, as income rises, demand rises, and the demand curve shifts to the right. As a result, both the equilibrium price and the equilibrium quantity.
