A demand curve is a graphical representation of the relationship between the price of a good or service and the quantity of that good or service that consumers are willing and able to purchase. In other words, it shows how much of a particular product or service consumers are willing to buy at different price points.

The demand curve is often derived from the price consumption curve, which shows the relationship between the price of a good or service and the quantity of that good or service consumed by consumers. This curve is also known as the Engel curve, named after the economist Ernst Engel, who first proposed the concept in the 19th century.

To derive the demand curve from the price consumption curve, we need to consider several factors that can affect the quantity of a good or service that consumers are willing and able to purchase at a given price. These factors include income, prices of substitute goods or services, and consumer preferences.

For example, if the price of a good or service increases, consumers may be less willing to purchase it, as they may consider it too expensive. On the other hand, if the price of a good or service decreases, consumers may be more willing to purchase it, as it becomes more affordable. This relationship between price and quantity demanded is known as the law of demand, which states that, all other things being equal, the quantity demanded of a good or service will decrease as the price increases, and vice versa.

In addition to the price of the good or service, the quantity demanded can also be affected by the income of consumers. If the income of consumers increases, they may be more willing and able to purchase more of a particular good or service, even if its price remains the same. On the other hand, if the income of consumers decreases, they may be less willing and able to purchase as much of a particular good or service, even if its price remains the same.

The prices of substitute goods or services can also affect the quantity demanded of a particular good or service. If the price of a substitute good or service increases, consumers may be more likely to purchase the original good or service, as it becomes a more attractive option in comparison. On the other hand, if the price of a substitute good or service decreases, consumers may be more likely to purchase the substitute good or service, as it becomes a more attractive option in comparison.

Finally, consumer preferences can also affect the quantity demanded of a particular good or service. If consumers have a strong preference for a particular good or service, they may be more likely to purchase it, even if its price is higher than that of a substitute good or service. On the other hand, if consumers do not have a strong preference for a particular good or service, they may be less likely to purchase it, even if its price is lower than that of a substitute good or service.

By considering these factors, we can derive the demand curve from the price consumption curve. The demand curve will generally have a negative slope, indicating the inverse relationship between price and quantity demanded. It is important to note that the demand curve is a hypothetical construct, and actual consumer behavior may differ from what is predicted by the demand curve due to a variety of factors, such as changes in consumer preferences or income.

Price Effect and Price Consumption Curve

And the demand for good X has decreased at every new equilibrium point as it is a Giffen good. The optimal consumption combination is e 1 on indifference curve U 1. In fig b , It is shown by point P. It has become familiar to millions through a diverse publishing program that includes scholarly works in all academic disciplines, bibles, music, school and college textbooks, business books, dictionaries and reference books, and academic journals. At the new equilibrium point E 2, the buyer purchases more units of good X and reduces the demand for good-Y because these goods are substitute goods. They are joined by a line to form the demand curve D. What refers to the slope of the consumption curve? This is shown by point R on the I 1 curve.

This is shown by point S on the curve I 2. Such an inelastic demand is reflected in a steeper demand curve. Here the consumer is increasing the demand for both good at every new equilibrium point than before. With the above information, we draw up the following demand schedule of the consumers. It is because of the complementary relationship between good X and Y.

Now suppose that income of the consumer increases. We can easily join these points with a continuous curve. Therefore the new demand curve will have a negative slope in case of a normal good. It is easier to understand the derivation of demand curve if it is drawn rightly below the indiff­erence curve diagram.

It can also be said as the slope of the budget line in a. In addition it regularly publishes special issues covering topics such as financial markets, public economics, and quantitative economic history. Further, the indifference curve drawn here shows combinations of the two goods X and money income or a composite good that give the same level of satisfaction. What is the meaning of demand curve? The demand curve is a vertical straight line showing that the consumption of good X is fixed as good X is a neutral good. But the latter method has an edge over the former.

INDIFFERENCE CURVES ANALYSIS: DERIVATION OF THE DEMAND CURVE

Here, The points P, Q and R in b corresponds to E, F and G points in a. Introduction This section is the ultimate exposition of the theory of indifference curves analysis wherein we are now going to discuss the derivation of the individual demand curve. With this information we can draw the demand curve, as is done in the lower portion of Fig. With the above information we draw up the demand schedule in Table 8. This is shown by point b. In the upper panel, the horizontal axis measures quantities of X while the vertical axis measures money income instead of the usual practice of measuring another good, say Y. Such income effect is different for different goods.

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. This is shown by point b. At this point, the consumer is spending Rs560 on 8 units of Maggi and Rs. Normal goods are also categorized into substitute one and a complementary one. This means that if p 1 falls, the demand for x 1 will increase. Assume that a consumer purchases good X from his limited money income. In the case of the complementary relationship between two goods, a good cannot be consumed in isolation form.

We can easily join these points with a continuous curve. Such goods for which income effect is negative are called Inferior Goods. This is shown by point b. It will not, however, slope to the left even if the good happens to be inferior for some individuals. These quantities Q A, Q B and Q c are added sideways in The slope of the demand curves of all the individuals and hence for the market is the same.

Price Consumption Curve (PCC)

Only when the negative income effect is powerful enough to outweigh the substitution effect can the demand curve slope upward to the right instead of sloping downward to the left. We have also assumed that good X and Y are normal substitutable goods to each other. At the initial equilibrium point, X 1 units of good X and Y 1 units of good Y is consumed. This is shown by point b. Here the consumer is increasing the demand for good Y only at every new equilibrium point than before.

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. At the initial equilibrium point, X 1 units of good X and Y 1 units of good Y is consumed. We have also assumed that good X and Y are normal substitutable goods to each other.
