1. Introduction
The Marginal Utility Theory has been around since the late 19th century as a way to describe consumer purchasing decisions. This theory states that when a consumer purchases a product, their decision is based on the incremental amount of satisfaction or utility that is provided. Therefore, the consumer is willing to pay the maximum amount for which they will receive a marginal unit of utility. This is why consumers will buy more of a product when the price is lower and not purchase when the price is set too high.
2. Assumptions
In order to understand the Marginal Utility Theory, one must first understand the assumptions associated with it. The first assumption is that all goods are substitutable. This means that the consumer can purchase one good over the other because they are seen as comparable in terms of price and satisfaction. Second, the consumer is assumed to be rational and is capable of making informed decisions that are advantageous to them. Lastly, that the consumer does not make purchases based on emotion or loyalty.
3. Explanation
When a consumer purchases a product, their decision is based on the amount of marginal utility that good will provide. This marginal utility is the incremental amount of satisfaction provided by a good after the first unit. For example, the first unit of chocolate may provide the consumer with the most amount of satisfaction. Each additional piece purchased will have less and less incremental utility. This is why the consumer will eventually stop purchasing at a certain point when they are unwilling to pay any more for a good that will provide them with no additional satisfaction.
4. Applications
The marginal utility theory can also be used to explain the concept of price elasticity. This is the ability of a good’s demand to change with changes in price. If a good has a high price elasticity, then a small change in the price of the good will result in a large change in quantity demanded. On the other hand, a good with low price elasticity will not be affected much by a change in price.
The marginal utility theory can also help explain the concept of price discrimination. This is the ability for a firm to charge different prices for the same good to different consumers. Companies use price discrimination to maximize profits. For example, a company may offer discounts to certain demographics of consumers in order to appeal to more price-sensitive customers.
5. Conclusion
The Marginal Utility Theory is a useful concept for understanding the purchasing decisions of consumers. This theory states that when a consumer purchases a product, their decision is based on the incremental amount of satisfaction or utility that is provided. Therefore, the consumer is willing to pay the maximum amount for which they will receive a marginal unit of utility. This theory is also useful in explaining the concept of price elasticity and price discrimination.
