what is the relationship between income effect and consumption

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 . Let's start with a thought experiment: if you were to receive a 10% The substitution effect is the change in consumption patterns due to a. Because you're referring to the income effect specifically the answer would be "b" . As incomes rise consumers are better able to afford premium.

When income grows, disposable income rises and thus consumers buy more goods. The result is an increase in the consumption of major purchases and non-essential goods. The increase in consumer expenditures is not a direct relationship to income. For every extra dollar earned, there may be a fraction spent on disposable income.

Low-income areas may actually see more in expenditures than in actual income at different times. The difference between income and consumption is how much is spent and left over as savings at the end of the month.

Price Demand Relationship: Normal, Inferior and Giffen Goods

There are many factors that determine why consumers choose to spend more on goods not required for day-to-day living expenses. These include stock market trends, tax laws, and even consumer optimism.

Example Income and Subsitution Effects For Normal and Inferior Goods

Economic experts look at historical data to predict future trends based on new market conditions. The Effect of Consumer Confidence Consumers won't spend money unless they are confident in their personal economic situation and strength. This means consumers feel good about having and keeping a job with the potential of promotion. Pay increases, stock portfolio rises and tax cuts can put more money in each person's pocket. As these conditions merge, consumer confidence increases.

Consumer confidence is the trust a buyer has that he can afford a purchase either today or in the near future. For example, consumer confidence is shown by homebuyer trends. This is a major purchase that takes decades to pay off.

Price Demand Relationship: Normal, Inferior and Giffen Goods

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. 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.

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.

In other words, even in case of inferior goods having weaker income effect, the demand curve will be downward sloping. Giffen Goods or Giffen Paradox: There is a third possibility. This is that there may be some inferior goods for which the negative income effect is strong or large enough to outweigh the substitution effect. In this case, quantity purchased of the good will fall as its price falls and quantity purchased of the good will rise as its price rises.

In other words, in this case quantity purchased or demanded will vary directly with price. Now, the income effect can be substantial only when the consumer is spending a very large proportion of his income on the good in question so that when price of the good falls, a good amount of income is released. If that good happens to be inferior good, the income effect will be negative as well as strong and may outweigh the substitution effect so that with the fall in price, the consumer will buy less of the good.

Such an inferior good in which case the consumer reduces its consumption when its price falls and increases its consumption when its price rises is called a Giffen good named after the British statistician, Sir Robert Giffen, who in the mid- nineteenth century is said to have claimed that when price of cheap common foodstuff like bread went up the people bought and consumed more bread.

A rise in the price of bread caused such a large decline in the purchasing power of the poor people that they were forced to cut down the consumption of meat and other more expensive food. Since bread even when its price was higher than before was still the cheapest food article, people consumed more of it and not less when its price went up. Similarly, when price of an inferior good, on which people spend a large proportion of their income, falls people will purchase less than before.

This is because the fall in price of an inferior good on which they spend a very large portion of their income causes such a large increase in their purchasing power that creates a large negative income effect.

They will therefore reduce the consumption of that good when its price falls since large negative income effect outweighs the substitution effect. The price-demand relationship in case of a Giffen good is illustrated in Fig.

With a certain given price-income situation depicted by the budget line PL1, the consumer is initially in equilibrium at Q on indifference curve IC1. With a fall in price of the good, the consumer shifts to point R on indifference curve IC2. It will be seen From Fig.

This is the net effect of the negative income effect which is here equal to HN which induces the consumer to buy less of good X and the substitution effect which is equal MH which induces the consumer to buy more of the good. Since the negative income effect HN is greater than the substitution effect MH, the net effect is the fall in quantity purchased of good X by MN with the fall in its price. Thus, the quantity demanded of a Giffen good varies directly with price.

Therefore, if a demand curve showing price-demand relationship of a Giffen good is drawn, it will slope upward.

For a good to be a Giffen good, the following three conditions are necessary: It follows from above that, indifference curve analysis enables us to derive a more general law of demand in the following composite form, consisting of three demand theorems to which the Marshallian law of demand constitutes a special case: In the case, a and b the Marshallian law of demand holds good and we get a downward sloping demand curve.
