What is marginal utility and how is it calculated?
Marginal utility is the additional utility derived from the consumption of one more unit of a particular good. It is calculated as the change in total utility divided by the change in total quantity.
What are the limitations of the marginal utility theory?
The limitations include consumer behavior not always following the theory, addiction, conspicuous consumption, speculation, the inability to observe utility, and the assumption that consumers cannot perform utility calculations.

Study Notes
Utility and Satisfaction
- Total utility refers to the total satisfaction or pleasure a consumer derives from consuming a particular quantity of a good or service.
- Total satisfaction is the maximum satisfaction a consumer can obtain from consuming a good or service.
Marginal Utility
- Marginal utility is the additional satisfaction or pleasure a consumer derives from consuming one more unit of a good or service.
- It is calculated by subtracting the total utility of the previous unit from the total utility of the current unit.
- Marginal utility is a measure of the change in total utility resulting from a one-unit change in the quantity consumed.
Limitations of Marginal Utility Theory
- The theory assumes that utility can be measured cardinally, which is not always possible.
- It assumes that the consumer's preferences remain constant, which is not always the case.
- The theory does not take into account the differences in the quality of goods and services.
Law of Diminishing Marginal Utility
- The law states that as the consumer consumes more units of a good or service, the marginal utility of each additional unit decreases.
- This means that the additional satisfaction derived from consuming one more unit of a good or service decreases as the consumer consumes more units.
Equi-Marginal Principle
- The Equi-Marginal Principle states that a consumer will allocate their income among different goods and services in a way that equalizes the marginal utility of the last unit of each good or service.
- The principle is based on the assumptions that the consumer's preferences are rational, that the consumer has perfect knowledge of the market, and that the consumer's budget is limited.
Importance of Utility
- Despite its drawbacks, learning about utility is important because it helps consumers make informed decisions about how to allocate their income.
- Understanding utility can help consumers maximize their satisfaction and make the most of their budget.
Conspicuous Consumption
- Conspicuous consumption refers to the practice of acquiring and displaying goods and services to publicly demonstrate one's wealth, status, or power.
- This concept is based on the idea that consumers derive satisfaction not only from the intrinsic value of a good or service but also from the social status and prestige it confers.
