## How the demand curve is derived under the cardinal theory approach?

To derive the demand curve based on the law of diminishing marginal utility, we measure the marginal utility of a commodity in terms of money as Marshall did. According to the cardinal utility approach, a consumer reaches his equilibrium where MUX=PX in case of one commodity.

### How do you derive the demand curve?

To derive a demand curve, you must know what each consumer is willing to pay for the product you are offering. Price and demand are directly related to each other. For example, if you charge 50 cents per cup of juice, maybe 100 people in your town would be willing to buy your juice.

How do you derive the demand curve through indifference curve?

8.47 money is measured on the Y-axis, while the quantity of the good X whose demand curve is to be derived is measured on the X-axis. An indifference map of a consumer is drawn along with the various budget lines showing different prices of the good X. Budget line PL1 shows that price of the good X is Rs. 15 per unit.

What are the main assumptions of Cardinal approach?

The basic assumption of the cardinal utility approach is that utilities of commodities can be quantified. According to Marshall, money is used to measure the utilities of commodities. This implies that the amount of money that a customer is willing to pay for a particular commodity is a measure of its utility.

## What is difference between cardinal and ordinal utility?

Cardinal utility is a function that determines the satisfaction of a commodity used by an individual and can be supported with a numeric value. On the other hand, ordinal utility defines that satisfaction of user goods can be ranked in order of preference but cannot be evaluated numerically.

### How do you derive the supply and demand curve?

Using the equation for a straight line, y = mx + b, we can determine the equations for the supply and demand curve to be the following: Demand: P = 15 – Q. Supply: P = 3 + Q.

What is total utility curve?

Total utility is usually defined as a quantifiable summation of satisfaction or happiness obtained from consuming multiple units of a particular good or service. Utility and total utility are used in the economic analysis of consumer behaviors within a marketplace.

What is the relationship between demand and utility?

Demand is an economic principle referring to a consumer’s desire for a particular product or service. Utility function describes the amount of satisfaction a consumer receives from a particular product or service.

## Is the indifference curve the demand curve?

Indifference curves can be used to derive a demand curve. If we assume a basket of only two types of good, and hold income constant, we can derive a demand curve which shows the quantity demanded for a good at different prices.

### What is in difference curve?

An indifference curve shows a combination of two goods that give a consumer equal satisfaction and utility thereby making the consumer indifferent. Along the curve, the consumer has an equal preference for the combinations of goods shown—i.e. is indifferent about any combination of goods on the curve.

What do you mean by Cardinal approach?

Definition: The Cardinal Utility approach is propounded by neo-classical economists, who believe that utility is measurable, and the customer can express his satisfaction in cardinal or quantitative numbers, such as 1,2,3, and so on.

How is the demand curve derived under cardinal utility analysis?

Here we will discuss the derivation of the demand curve under cardinal utility analysis in the case of one commodity and case of two commodities. To derive the demand curve based on the law of diminishing marginal utility, we measure the marginal utility of a commodity in terms of money as Marshall did.

## How are cardinal and ordinal approaches to the demand function?

Cardinal and ordinal approaches to the derivation of the demand function for Managerial Economics Mcom Delhi University We have already seen how the price consumption curve traces the effect of a change in price of a good on its quantity demanded.

### How did Alfred Marshall derive the demand curve?

Dr. Alfred Marshall derived the demand curve with the aid of law of diminishing marginal utility. The law of diminishing marginal utility states that as the consumer purchases more and more units of a commodity, he gets less and less utility from the successive units of the expenditure.

How is the demand curve obtained in DD 1?

DD 1 is the demand curve obtained by joining points a and b. The demand curve is downward sloping showing inverse relationship between price and quantity demanded as good X is a normal good. In this section we are going to derive the consumer’s demand curve from the price consumption curve in the case of inferior goods.
