INCOME EFFECT - WikiEducator
The relationship among wealth, consumption, and happiness is an ancient things such as their income, what they buy, and what their most important life goals are. . I am refereeing to these common measures of life satisfaction and affect. The main goal of this work is, therefore, to measure wealth effects for the euro . The trend relationship among consumption, asset wealth and labor income is. We find that consumption has a positive effect on happiness. for focusing on consumption is that examining the relationship between income and .. The pursuit of external goals, such as material goods and image, is.
Thus, a rise in income of the consumer may lead his demand for a good to rise, fall or not change at all. It is important to note here that, the knowledge of preferences of the consumer is essential to predict whether a particular good is inferior or normal.
Normal goods[ edit ] Figure 2: Income-consumption curve for Normal goods In the figure 2 to the left, B1, B2 and B3 are the different budget lines and I1, I2 and I3 are the indifference curves that are available to the consumer.
As shown earlier, as the income of the consumer rises, the budget line moves outwards parallel to itself. The greater the shifts of the demand curve to the right, the greater the income-elasticity of demand. In such a case, the goods will be normal goods. The figure on the right figure 3shows the consumption patterns of the consumer of two goods X1 and X2, the prices of which are p1 and p2 respectively, where B1 and B2 are the budget lines and I1 and I2 are the indifference curves.
This is shown by budget constraint P2L2 in Figure. When consumer's income decreases, the budget constraint moves inwards. This is shown by budget constraint P1L1 in Figure. The optimal consumption is located at point e1 at which the consumer buys OX1 units of good X and OY1 units of good Y. Similarly, when consumer's income increases, the budget constraint moves outwards. This is shown by budget constraint P2L2.
The optimal consumption is now located at point e2, at which the consumer buys OX2 units of good X and OY2 units of good Y. Sum Up The curve obtained by joining optimal consumption combinations such as e1, e and e2 is called the income consumption curve ICC. The ICC in Figure. Here income effect is positive for goods X and Y. Negative Income Effect We now study negative income effect. Good X is an inferior good and good Y is a normal good. Negative Income Effect When income of the consumer increases, then entire budget constraint shifts outwards and it is a parallel shift.
This is shown by budget constraint P1L1. The optimal consumption is now located at point e1, at which the consumer now buys OX1 units of good X and OY1 units of good Y. This movement along the indifference curve from Q to Q1 is known as the substitution effect.

In substitution effect, prices of both the commodities change price of commodity Y increases and price of commodity X decreases. However, in price effect, price of any one of the commodities changes. Thus, price effect is the change in the quantity of commodities or services purchased due to a change in the price of any one of the commodities.
How Do Income Effect, Substitution Effect and Price Effect Influence Consumer's Equilibrium?
Let us consider two commodities, namely commodity X and commodity Y. Price of commodity X changes. Suppose price of commodity X decreases. The points C1, C2, C3 and C4 denote respective equilibrium combinations.

In the above figure, the PCC has a positive slope. Suppose the price of commodity A continuously decreases. At this equilibrium point, the consumer buys OM1 quantity of commodity A. If you connect all equilibrium points P1, P2 and P3you will be able to get the price consumption curve.
