Price, income, and substitution effect are all important concepts in economics that help to explain how consumers and producers make decisions about what to buy, how much to produce, and how prices are determined in the market. These concepts are closely related and can have a significant impact on the overall functioning of an economy.
The price effect refers to the way in which changes in the price of a good or service can affect the quantity of that good or service that is demanded by consumers. When the price of a good or service increases, the quantity demanded may decrease as consumers are less willing to pay the higher price. This is known as the law of demand. On the other hand, if the price of a good or service decreases, the quantity demanded may increase as more consumers are willing to pay the lower price.
The income effect refers to the way in which changes in a person's income can affect the quantity of a good or service that they demand. If a person's income increases, they may be able to afford to buy more of a good or service, leading to an increase in the quantity demanded. Conversely, if a person's income decreases, they may have to cut back on their spending and reduce the quantity of a good or service that they demand.
The substitution effect refers to the way in which changes in the price of a good or service can affect the choice of goods or services that consumers make. For example, if the price of a good or service increases, consumers may choose to substitute a different, lower-priced good or service in its place. This can lead to a decrease in the quantity demanded of the more expensive good or service and an increase in the quantity demanded of the substitute good or service.
All three of these effects – the price effect, the income effect, and the substitution effect – can have a significant impact on the overall functioning of an economy. By understanding how these effects work, economists can better predict how changes in prices and incomes will affect the demand for goods and services, which can help to inform economic policy decisions.
Consumer Equilibrium: Effects On Income, Substitution, Price
When companies outsource part of their operations, they are demonstrating the substitution effect. It means that the increase in real income or purchasing power of the consumer as a result of the fall in price of X is equal to PA in terms of Y or L 1B in terms of X Movement of the consumer from Q on indifference curve IC 1 to S on the higher indifference curve IC 2 along the income consumption curve is the result of income effect of the price change. Price effect: Thus, in the case of normal goods, the positive income effect and negative substitution effect vary in the same direction, leads to an increase in the quantity demanded of apple juice. This makes one commodity cheaper and the other commodity costlier. Graphical Representation- Inferior Goods: Price Effect for inferior goods In fig, The X-axis shows the quantity of inferior Commodity-1 and the Y-axis shows the quantity of Commodity-2. This graph shows the substitution effect and income effect of a price increase for a normal good.
In short, the price effect comprises of income effect and substitution effect and the direction in which quantity demanded change due to change in the direction of income and substitution effect. As a result, the consumer is able to purchase more units of both commodities X and Y. Suppose X is a Giffen good and the initial equilibrium point is R where the budget line PQ is tangent to the indifference curve l 1. Decomposition of Price Effect into Substitution and Income Effects Graphically the decomposition of price effect into substitution and income effects is done using the indifference curve with the budget line of the consumer. The change in relative price results in the consumer to rearrange the purchase of good X and Y and as a result, the consumer will attend equilibrium at higher indifference curve IC 2 at point E 2.

Income Effect vs. Substitution Effect: What's the Difference?
In other words, the relation between price and quantity demanded being inverse, the substitution effect is negative. Thus, The overall price effect is negative with respect to price. In the case of a normal good, the substitution effect is negative as to maintain the same level of satisfaction on the same indifference curve, a consumer increases the quantity demand of goods X whose price has fallen and decreased the quantity demand for good Y as the price of X becomes relatively cheaper than the price of Y. This shift from E 3 to E 2 is known as the income effect. At point E, the consumer consumes quantities OQx of X and OQy of Y to yield maximum satisfaction.
In Figure 1, when the consumer is at point J and moves to point M, there is no difference in the satisfaction level at both points that lie on the same curve IC1. This adjustment in income is called compensating variations and is shown graphically by a parallel shift of the new budget line until it become tangent to the initial indifference curve. The substitution effect is a possible reaction towards the price change. Now, a line AB is drawn parallel to PL 1 so that it touches the indifference curve IC 2 at S. When there is a change in the price of a commodity then there is a change in demand.
Decomposition of Price Effect into Substitution and Income Effects
The movement of equilibrium point from D to F represents the increase in quantity demanded of apple juice from OX to OZ units. Thus, the amount of money how much to reduce is known in this case. Let us understand this with the help of Figure 3 Line AB represents the original budget line. Here we discuss the top 4 differences between substitution effect vs. This is identified as the substitution effect. This movement from Q to S on the same indifference curve IC 1 represents the substitution effect since it occurs due to the change in relative prices alone, real income remaining constant. Here we will discuss the Hicksian approach of decomposition of price effect into substitution and income effects.
Breaking up Price Effect into Income and Substitution Effect (with diagram)
If a majority of the population is vegan or vegetarian, however, then a fall in the price of chicken will not lead to a rise in its demand. AB is the budget line that intersects IC2 at point E. It will be seen from Fig. Suppose the price of commodity A continuously decreases. Suppose initially the consumer is in equilibrium at point R on the budget line PQ where the indifference curve I 1 is tangent to it at point R in Figure 12. Now, X being relatively cheaper than before, the consumer in order to maximise his satisfaction in the new price income situation substitutes X for Y.
Now, if his money income is reduced by the compensating variation in income so that he is forced to come back to the original indifference curve IC 1 he would buy more of X since X has now become relatively cheaper than before. Let us consider two commodities, namely commodity X and commodity Y. The usage of bus services instead of trains or airplanes is regarded as an inferior good. It is very difficult to teach more students in a personal touch. We saw that a fall in the price of good X, given the price of Y, increases its demand.
In such a case, one commodity becomes more affordable than the other. Supply is the availability of something that is needed. Price Effect as a combination explains the nature of the response in quantity purchased due to change in price. The author writes that the explanation starts from the understating of the relation between human wants and available resources. The movement from point H on the lower indifference curve I 1 to point T on the high indifference curve I 2 is the income effect of the fall in the price of good X. The second type of ICC curve may have a positive slope in the beginning but become and stay horizontal beyond a certain point when the income of the consumer continues to increase.
