Marginal Utility Theory
Marginal Utility Theory is a fundamental economic theory that is used to explain the price determination in a free market. The theory states that the value of an item to someone is not based on its cost, but on the utility or satisfaction it provides to the person possessing it. It suggests that the value of an item is always changing as more units are purchased. With each additional item purchased, the marginal utility or satisfaction declines as the consumer’s needs are satisfied.
The concept of marginal utility was first introduced by the Austrian economist Carl Menger in the late 19th century. He theorized that the value of a good is derived from the satisfaction (utility) that it provides to the consumer. In other words, the value of a good is determined by the amount of satisfaction a consumer receives from it. This means that the value of a good is always changing as more units are purchased and the consumer’s needs are satiated.
The theory explains that, as more units of a good are purchased and consumed, the additional utility (satisfaction) gained from each successive purchase diminishes. The marginal utility, or utility of the last unit, is the determining factor in how much a consumer is willing to pay for that good. As the price of a good increases, the consumer buys less of it since the total amount of satisfaction received is lower. The consumer continues buying the good until the marginal utility is equal to the market price of the good.
Marginal utility theory is used to explain changes in demand for a good or service. When the marginal utility of a good is greater than the price, the demand for the good increases. On the other hand, when the price is greater than the marginal utility, demand for the good decreases. This can be seen when a consumer uses their scarce resources, such as money, to purchase more of something they want. As they purchase more of the good, the marginal utility of that good decreases, while the price remains the same. The consumer will stop purchasing the good when the marginal utility of the good is equal to the price.
The concept of marginal utility is also used to explain why consumers prefer certain goods more than others. For example, a consumer may prefer to buy organic food, even though it costs more, because they are willing to pay more for the health benefits they perceive. The consumer’s willingness to pay more for organic food implies that the marginal utility of organic food is greater than the price.
Marginal utility theory is a foundational economic principle used to explain the price mechanism in a free market. It states that the value of a good is determined by the amount of satisfaction or utility it provides to the consumer, and not the cost of production. The marginal utility of the last unit purchased determines the willingness of a consumer to pay for that good. As the price of a good increases, the consumer buys less of it since the total amount of satisfaction received is lower. The consumer continues buying the good until the marginal utility is equal to the market price. This theory is also used to explain why consumers may value certain goods more than others.
