Income Effect: Income Consumption Curve (with curve diagram)
Price Demand Relationship: Normal, Inferior and Giffen Goods a combination of income effect and substitution effect explains relationship between price and A distinct advantage of viewing the price effect as a sum of income effect and . its consumption when its price falls and increases its consumption when its price . The economic concepts of income effect and substitution effect express changes in the market and how these changes impact consumption. Let's begin with a concrete example illustrating how changes in income level affect For analyzing the possible effect of a change in price on consumption, let's show a connection between prices and quantity demanded—are based on the.
Consequently, his satisfaction further increases. Income consumption curve traces out the income effect on the quantity consumed of the goods. Income effect can either be positive or negative.
Price Demand Relationship: Normal, Inferior and Giffen Goods
Income effect for a good is said to be positive when with the increase in income of the consumer, his consumption of the good also increases. This is the normal good case.
When the income effect of both the goods represented on the two axes of the figure is positive, the income consumption curve ICQ will slope upward to the right as in Fig. Only the upward- sloping income consumption curve can show rising consumption of the two goods as income increases. However, for some goods, income effect is negative.
Income effect for a good is said to be negative when with the increases in his income, the consumer reduces his consumption of the good. Such goods for which income effect is negative are called Inferior Goods.

When with the increase in his income, the consumer begins to consume superior goods, the consumption or quantity purchased by him of the inferior goods falls. When the people are poor, they cannot afford to buy the superior goods which are often more expensive. Hence as they become richer and can afford to buy more expensive goods they switch to the consumption of superior and better quality goods.
This is a major purchase that takes decades to pay off. A buyer must feel good about the economy, as well as feeling secure about his personal financial situation to take on such a major purchase.

Supply and demand have a strong effect on whether buyers feel there is a need to purchase now. Going back to the house purchasing example, if there are not a lot of homes for sale but interest rates are low, supply is down but demand may increase.
This could lead to higher buying desires among consumers trying to get in while they can for the best deal possible. A business should consider its own inventory levels when seeing consumption schedules and consumer confidence ratings. When inventory increases for any item, it's less urgent to buy it. When inventory builds up in a sector, such as in the automotive industry, it suggests reduced consumer confidence where conditions drive savings more than spending.
A business in this sector would want to take heed and keep inventory levels manageable to prevent sitting on inventory stock for extended periods of time. While no business can control consumer confidence, it can take proactive measures to protect itself as buyer trends change. In order to understand the way in which price-demand relationship is established in indifference curve analysis, consider Fig 8. Given the price of two goods and his income represented by the budget line PL1, the consumer will be in equilibrium at Q on indifference curve IC1.
Let us suppose that price of X falls, price of Y and his money income remaining unchanged so that budget line now shifts to PL2. The consumer will now be in equilibrium at a point on the new budget line PL2.
Now, it can be proved that in case of normal goods the new equilibrium point on budget line PL2 thereby that the quantity demanded of the good X will increase as its price falls. The direction and magnitude of the change in quantity demanded as a result of fall in price of a good depend upon the direction and strength of income effect on the one hand and substitution effect on the other.
As for normal goods, the income effect is positive, it will work towards increasing the quantity demanded of good X when its price falls.
The substitution effect which is always negative and operates so as to raise the quantity demanded of the good if its price falls and reduces the quantity demanded of the good if its price rises. Thus, in case of normal goods both the income effect when positive and negative substitution effect work in the same direction and cause increase in the quantity purchased of good X whose price has fallen with the result that the new equilibrium point will lie to the right of the original equilibrium point Q such as point R in Fig.
Substitution effect causes MK increase in quantity demanded.

- What is the relationship between income effect and consumption?
Income effect which is positive here also leads to the increase in quantity demand by KN. Each effect therefore reinforces the other. To sum up, the income effect and substitution effect in case of normal goods work in the same direction and will lead to the increase in quantity demanded of the good whose price has fallen. In other words, quantity purchased of a normal good will vary inversely with its price as in its case income effect is positive.
In case of inferior goods the income effect will work in opposite direction to the substitution effect. When price of an inferior good falls, its negative income effect will tend to reduce the quantity purchased, while the substitution effect will tend to increase the quantity purchased. But normally it happens that negative income effect of change in price is not large enough to outweigh the substitution effect.
This is so because a consumer spends a very small proportion of his income on a single commodity and when price of a commodity falls, a very little income is released. In other words, income effect even when negative is generally too weak to outweigh the substitution effect.
The Relationship Between Income & Expenditure
It follows therefore that as a result of fall in price of a good the. Thus even in most cases of inferior goods the net result of the fall in price will be increase in its quantity demanded. It is thus clear that in a majority of inferior goods quantities demanded of the good will vary inversely with price and the Marshallian law of demand will hold good. The price-demand relationship in case of inferior goods having weaker income effect is illustrated in Figure 8.
It will be seen from Fig. But the income effect is negative and is equal to HT.
If income effect alone was working, it would have caused the consumer to buy HT less of good X. But substitution effect is universally present and always induces the consumer to buy more of the relatively cheaper good. Therefore, the net effect of the fall in price of good X is the increase in quantity demanded by MT. Hence we conclude that in case of inferior goods, quantity demanded varies inversely with price when negative income effect is weaker than the substitution effect.
