Let`s look at another example. In the next photo we see a person enjoying a horse ride along the beach. Your first hour brings a high degree of utility. However, over time, sun exposure and exhaustion slowly reduce the marginal utility he receives from each additional hour of his trip. The law of the decrease in marginal utility is directly related to the concept of lower prices. If the usefulness of a product decreases with increased consumption, consumers are willing to pay lower amounts for more of the product. Suppose a person pays $100 for a vacuum cleaner. Since it has little value for a second vacuum cleaner, the same person is willing to pay only $20 for a second vacuum cleaner. Now that we understand that benefit measures the satisfaction a person receives from consuming a good or service, we can think about how the benefit changes when a person consumes more than one good. In our example, the benefit is highest for the first piece of chocolate cake that the person eats.
Let`s say that the person has saved space for dessert and the first piece of cake perfectly satisfies his sweet tooth. The above example implicitly uses the continuity hypothesis. For example, you can see on the graph that 3.5 plates of food give the consumer 27.5 units of use. If we assume a continuous utility function, then the marginal utility of the umpteenth unit of consumption is simply the slope (or derivation) of the entire utility function at x units. The decrease in marginal utility is the decrease in enjoyment through the consumption or purchase of an additional good. For example, a consumer buys a bag of chocolate and after one or two pieces, its usefulness increases, but after a few pieces, its usefulness will decrease with each additional piece consumed – and finally, after enough pieces, this will probably lead to negative equity. Buffets are a great example of restaurants that depend on decreasing marginal utility. For a price, you can eat all the food you want. The reason buffets work economically is that people reach a point where the benefit (pleasure) from an extra plate of food is not worth the cost of eating that extra plate. In this example, the owner got the benefit or satisfaction of the first additional employee, and he got good marginal returns because he could produce more with the new employee.
However, hiring a second employee did not allow the owner to obtain benefits, and marginal returns did not increase with the additional employee. In this case, the marginal utility and marginal returns with the second employee are zero, because the demand and everything else have remained the same. You may be wondering how economists measure what is in someone`s best interest? This is where the concept of utility comes into play. Think of benefit as the benefit a person receives from consuming a good or service. In our example, the benefit is the satisfaction a person gains by eating a piece of chocolate cake. It is important to understand that the concept of utility is a relative concept. Different people get different levels of satisfaction from eating a chocolate cake, depending on their preferences. The law of diminishing marginal utility is best understood by analogy. Let`s take the following example: The law of diminishing marginal utility holds that in the real world, each additional soda consumed provides fewer marginal benefits to the consumer than the previous one. For example, if you drink a soda and earn 20 units of total value, the second soda you drink will offer a little less value (say, 15 points) with a total value of 35. A third offers even less value (e.g.
10 points). In other words, each additional drink offers less marginal utility than the previous one. The law of diminishing marginal utility can have broader applications, such as helping economists and governments assess changes in a country`s economy. For example, if a government wants to help the economy as a whole, it may choose to give more money to the poor because they will be more valuable for every dollar. Someone with only $5,000 will attach more value to every extra dollar than someone on $100,000. Claim that cookies are the good you consume. With the first cookie, the marginal utility is the highest – 20 utils. The second cookie provides a slightly lower marginal utility of 16 utilities. The third brings 8 and the fourth brings zero. In this example, if each additional cookie is consumed, the marginal utility gained is less than that of the previous cookie. Think about it logically – if you eat more cookies, you don`t want so many cookies; You may even start to feel sick when you eat more. This illustrates the decrease in marginal utility.
What if your partner had also bought you a balloon? A third ball probably doesn`t have much value for you. And a fourth bullet would usually mean even less. The reduced value of each sphere is an example of the law of the decrease of marginal utility. The law of diminishing marginal utility makes many assumptions about consumer behavior. Here are some examples: Remember that “profit” is a rather arbitrary measure. There is no universal benefit that comes from eating a slice of pizza, for example. Everyone will rate a good or service differently. Instead, think of utility as a theoretical tool that economists use to study the value and benefits that different products and services offer consumers. To calculate the decreasing marginal utility, you must first assign a value to the consumption of the first unit of a product. The value you assign is arbitrary. For example, you can assign a value of 10 to drinking a can of soda, while another can assign a value of 1.
Now that we know what the concept of diminishing marginal utility is, let`s take a look at a concrete example. For example, necessities such as food and water offer a very high value or benefit to a consumer. That is, until the consumer receives enough food and water to meet his physical needs. Once they satisfy this need, the marginal utility of these goods would diminish. At this stage, the consumer may prefer to buy other goods that offer a more marginal utility. The example above also helps explain why demand curves fall downward in microeconomic models, as each additional unit of a good or service has a less valuable benefit.
