Solution

For a normal commodity, an increase in income of the consumers means an increase in its demand. Accordingly, the demand curve shifts rightward and both equilibrium price and equilibrium quantity tend to increase. In the given diagram, the actual demand curve DD and actual supply curve SS intersect at point E (i.e. equilibrium point). When the income of the buyer increases, the demand for normal goods also rises and the demand curve shifts rightward from DD to D1D1. (adsbygoogle = window.adsbygoogle || []).push({}); As a result, equilibrium price and quantity both are increased from OP to OP1 and OQ to OQ1

How does an equilibrium price of a normal commodity change when the income of its buyers fall explain the chain of effects?

For a normal commodity, decrease in income of the buyers means decrease in its demand. Accordingly, demand curve shifts leftward and both equilibrium price and equilibrium quantity tend to decrease.

How will an increase in the income of a buyer of a normal good affect its equilibrium price and equilibrium quantity explain with the help of a diagram?

In case of inferior goods when there is increase in the income of the buyer the equilibrium quantity will reduce as the consumer will use its excess purchasing power to purchase superior goods in place of inferior goods.

How does change in the income of the buyer of a commodity affect its demand explain?

Understanding the Income Effect For normal economic goods, when real consumer income rises, consumers will demand a greater quantity of goods for purchase. The income effect and substitution effect are related economic concepts in consumer choice theory.
