The economy, that science that attempts to decipher the complex world of financial decisions, brings us today a fascinating concept: the theory of diminishing marginal utility. Don't be scared by the name, which although it sounds like expert jargon, is something that you experience daily without realizing it.
Imagine you're at your favorite ice cream shop. You're craving chocolate ice cream, so you order one. That first ice cream tastes like heaven.It's so good that you decide to order another. The second one is also delicious, but you notice that you're not enjoying it as much as you did with the first. If you venture out for a third, you'll probably start to feel a little stuffed. And if you kept eating ice cream, you'd reach a point where you wouldn't even want to look at it.
What you have just experienced is precisely the diminishing marginal utility theory in actionThis theory, fundamental in microeconomics, It explains how the pleasure or satisfaction we get from consuming something decreases as we increase its consumption..
In more technical terms, marginal utility is the additional benefit we obtain by consuming one more unit of a good or serviceAnd when we talk about it being “decreasing,” we mean that this additional benefit decreases with each additional unit we consume.
But don't think this only applies to desserts. The theory of diminishing marginal utility It has implications for virtually every aspect of the economy and our lives.Let's look at some examples:
- Salaries and work motivation: A €100 raise can be very motivating for someone who earns €1000 a month. But that same €100 raise probably won't have the same effect on someone who already earns €10000 a month. The marginal utility of money also decreases.
- Advertising and marketing: The first few times we see an ad, it can catch our attention and influence our purchasing decision. However, If we are constantly bombarded with the same advertisement, we are likely to start ignoring it or even find it repulsive.
- Public policies: Governments use this concept to design progressive tax systems, where those who earn more pay a higher percentage of taxes, based on the idea that the marginal value of money is lower for them.
The paradox of water and diamonds
One of the most interesting applications of this theory is the resolution of the famous diamond-water paradox. Why is water, essential for life, so cheap, while diamonds, which are not necessary for survival, are so expensive?
The answer lies in marginal utility. Water is so abundant that its marginal utility is low. Diamonds, on the other hand, are scarce, so each additional unit still has a high marginal value. It is not the total value that determines the price, but the value of the last unit consumed..
Criticisms and limitations
Like any economic theory, that of diminishing marginal utility is not exempt from criticismSome argue that:
- It is not always fulfilled: There are goods, such as addictive drugs, where marginal utility may initially increase.
- It's difficult to measure: The utility is a subjective concept and personal, which complicates its precise quantification.
- Oversimplifies: It does not take into account factors such as the social context or emotions in consumer decisions.
Knowing the theory of diminishing marginal utility can help you make better financial decisions. For example: uterine
1. Smart budget: Distribute your money among different spending categories to maximize your overall satisfaction, instead of spending it all on one thing.
2. Conscious consumption: Be aware of when you have reached the saturation point in the consumption of something and avoid excess.
3. Valuation of time: Apply the concept to your use of time. The first hours of work are usually more productive than the last ones.
In short, the theory of diminishing marginal utility teaches us that more is not always better. It invites us to reflect on our consumption patterns and to seek a balance that maximizes our overall satisfaction. And you, have you noticed how this theory works in your daily life? The next time you are faced with a consumption decision, remember that sometimes, less is more.
