“If consumers buy less of a commodity when their incomes rise, they will surely buy less when the price of the commodity rises.” Explain this statement with the help of income and substitution effect?

Expert Solution

The income effect states that if the income of consumers will increase then he will start buying more of a good if it is a superior good. But in case of inferior goods, the consumer will search for a better product. Suppose a person buy normal clothes earlier but when his income increase then he will start buying better clothes than before. This is because income is linked with status. Thus he will buy less of those commodity which was purchased earlier because of low income. Suppose a person is presently using cooler and if income increased then he will prefer Air conditioner.

As far as substitution effect is concerned, if the price of a commodity increase then the buyer will search for a substitute. Thus the demand for the product whose price has been increased will be effected. Just for example, when price of sugar will increase then many people will start buying jaggery. This will negatively impact the demand for sugar.

The law of demand says that when the price of something goes down people buy less of it (and vice versa), all other things being equal. Such a change is referred to as an increase in quantity demanded and is shown by a movement down along a given demand curve. By contrast, an increase in demand is shown by a rightward shift in the entire demand curve. 1. Some people seem to believe that there are goods for which the...

Economists have traditionally assumed that consumers are rational: they use their incomes and time to make themselves as well off as they can. But recent research shows that consumers also want to be treated fairly. Surveys have found that many consumers believe it is unfair for firms to raise the prices of some goods after a sharp increase in demand (for example, following a tropical storm) while the same increase in price following a decrease in supply is deemed to...
