The cardinal utility approach is a method of analyzing and measuring consumer utility, or satisfaction, in economics. It is based on the assumption that utility, or the satisfaction a consumer derives from a good or service, can be quantified and measured on a numerical scale. This approach contrasts with the ordinal utility approach, which assumes that utility can only be ranked or ordered, but not quantified.

The concept of utility was first introduced by the economist Jeremy Bentham in the 18th century as a way to measure the happiness or pleasure that an individual derives from a particular action or consumption choice. Bentham believed that utility could be quantified and that the utility of different actions or choices could be compared and ranked based on their ability to produce happiness or pleasure.

The cardinal utility approach was developed in the late 19th and early 20th centuries by economists such as Alfred Marshall and Francis Edgeworth. They argued that utility could be measured and quantified using a numerical scale, rather than simply ranked or ordered. This approach was based on the assumption that there is a consistent and stable relationship between the amount of a good or service consumed and the resulting utility or satisfaction.

Under the cardinal utility approach, the utility derived from a particular good or service is considered to be a function of the amount consumed. For example, the utility of a slice of pizza may increase as the number of slices consumed increases, but at some point, the marginal utility of each additional slice will begin to decrease. This is known as the law of diminishing marginal utility, which states that the additional utility derived from consuming an additional unit of a good or service will eventually decrease as the quantity consumed increases.

The cardinal utility approach has been widely used in economics to analyze consumer behavior and to understand how individuals make consumption decisions. It has also been used to analyze the effects of changes in the price of goods and services on consumer demand, as well as to evaluate the efficiency of different market structures and policies.

However, the cardinal utility approach has been criticized by some economists for its assumption that utility can be accurately measured and quantified. Some have argued that utility is subjective and may vary significantly from person to person, making it difficult to accurately measure and compare. Despite these criticisms, the cardinal utility approach remains an important and widely used tool in economics for understanding and analyzing consumer behavior.

Cardinal Utility Approach

cardinal utility approach definition

Hicks and Allen, following the footsteps of Pareto, introduced the technique of indifference curves. TOTAL UTILITY AND MARGINAL UTILITY: Difference between Total Utility and Marginal Utility: People buy goods because they get satisfaction from them. Many theories describe the level of satisfaction. PRACTICAL IMPORTANCE OF LAW OF DIMINISHING MARGINAL UTILITY: The law of diminishing utility has great practical importance in economics. In given span of time, the more of a specific product a consumer obtains, the less anxious he is to get more units of that product or we can say that as more units of a good are consumed, additional units will provide less additional satisfaction than previous units. The attempt by Walras to use subjective units utils for the measurement of utility does not provide any satisfactory solution.

What is the main difference between cardinal and ordinal utility approaches?

cardinal utility approach definition

New York: John Wiley and Sons. The satisfaction derived from various commodities cannot be measured objectively. Ordinal Utility is the utility where the satisfaction derived by consuming a product cannot be expressed numerically. Thus in response to decrease in the price from Px to Px 1, the quantity demanded of a good X increases from OQ 1 to OQ 2. The law of equilibrium utility is known, by various names. Concepts of Utility: Following are important concepts of utility: Utility: The characteristics of a commodity or service is to satisfy a human want.

For example, a person who earns Tk 90, 000 per month attaches less importance to Tk 10. What is the concept of ordinal utility? What is Cardinalist and Ordinalist approach? In other words, we can say that as a person gets more and more of a particular commodity, the marginal utility of the successive units begins to diminish. The total utility increases, but at a decreasing rate, up to quantity x, and then starts declining figure 2. It is also assumed that the marginal utility obtained from the consumption of a good diminishes continuously as its consumption is increased. Suppose a man is very thirsty. In fact they law of diminishing marginal utility, the more we have of a thing, and the less we want additional increment of it.

If the units are too small, then the marginal utility instead of falling may increase up to a few units. As a man gets more and more units of a commodity, the desire of his that good goes on falling. After this point, marginal utility becomes negative. Here it may be noted that the utility of then successive units consumed diminishes not because they are not of inferior in quality than that of others. The neo-classical economist developed the theory of consumption based on the assumption that utility is measurable and can be expressed cardinally. Ordinal numbers tell the order of how things are set, they show the position or the rank of something.

If he pushes the purchase further from his point of equilibrium, then the marginal utility of the commodity will be less than that of price and the household will be loser. Universita Dell'Insubria Facolta di Economia. The utility can be measured in cardinal numbers such as 1, 3, 10, 15, etc. It is in fact difference between the total utility and the actually money spent. What is ordinal approach to consumer behavior? If the marginal utility of the commodity is higher than that of price, he purchases that commodity.

It means, it is possible to express utility that an individual derives from consuming a commodity in quantitative terms. The utility is subjective in nature. Marginal utility is the change in the total utility that results from unit one unit change in consumption of the commodity within a given period of time". Therefore, cardinal utility theory is also known as neo-classical utility theory. The law of equilibrium utility is known, by various names. Ordinal numbers indicate the order or rank of things in a set e. The utility is expressed in imaginary cardinal numbers tells us a great deal about the preference of the consumer for a good.

Then we say the individual seeks to maximize some function of those numbers. The utility of the successive units falls simply because they happen to be consumed afterwards. The consumer buys a commodity because it gives him satisfaction. The system of modern taxation is therefore, based on the law of diminishing marginal utility. This law is known as the Law of maximum Satisfaction because a consumer tries to get the maximum satisfaction from his limited resources by so planning his expenditure that the marginal utility of a rupee spent in one use is the same as the marginal utility of a rupee spent on another use. } In this example from Majumdar x 1 is 0, and by choosing the scale so that the utility of x 2 equals 1, gives 0. For example, if a consumer develops a taste for wine, the additional units of wine may increase the marginal utility to a drunkard.

The assump­tion of constant utility of money is also unrealistic. As a result of scarcity of recourse, the consumer cannot satisfy all his wants. This is the axiom of diminishing marginal utility. From this, we conclude that the law of demand the law of diminishing are very closely inter-related. ADVERTISEMENTS: The utility of each commodity is measurable.

But what about the utility of money to him? Consequently at diminishing price, the quantity demanded of the good x increases as is shown in fig. But a man who gets Tk 1000 per month, the value of Tk 10 to him is very high. The utility of the successive units falls simply because they happen to be consumed afterwards. A special point occurs when the consumer consumes fifth apple. If he drinks third glass of water, the utility of the third glass will be less than that of second and so on. The law of demand, the theory of consumers surplus, and the equilibrium in the distribution of expenditure are derived from the law of diminishing marginal utility.
