Introduction
Start with a concise introduction to the mental model, what it is, and why it matters. Aim to hook the reader’s interest by highlighting the value of understanding this model.
Importance: Briefly mention the benefits or impact of applying this mental model in decision-making, problem-solving, or other relevant areas.
What is Marginal Utility?
Definition: Marginal utility is a concept in economics that refers to the additional satisfaction or benefit a consumer gains from consuming one more unit of a good or service.
Origin and Context: The principle of marginal utility was developed in the 19th century by economists such as William Stanley Jevons, Carl Menger, and Léon Walras, marking the beginning of the marginal revolution in economic thought.
How Marginal Utility Works
Explanation: Marginal utility shows how the satisfaction derived from each additional unit of consumption decreases. As you consume more of a good, the less utility or satisfaction you will get from each additional unit.
Example 1: Purchasing a Coffee
Description: Consider the action of buying coffee. The first coffee of the morning might provide substantial utility due to its refreshing effect. However, if a person drinks a second or third coffee, the utility received from each subsequent cup decreases.
Analysis: This demonstrates the principle of diminishing marginal utility, indicating the decrease in satisfaction with each additional coffee consumed.
Example 2: Streaming Services Subscription
Description: When deciding whether to subscribe to another streaming service, a consumer weighs the marginal utility of the additional content against the cost. Initially, adding a service may offer significant new entertainment value. Over time, as more services are added, the utility of the next subscription decreases.
Analysis: This example illustrates how understanding marginal utility can aid in making more informed, rational decisions about purchases and investments.
How to Apply Marginal Utility in Your Decision-Making
Practical Tips: To apply this concept, always consider the additional benefit of any further consumption or investment. Question whether the benefit outweighs the cost or if it declines with each additional unit.
Challenges and Considerations: Note that quantifying satisfaction or utility can be subjective and varies between individuals. It’s crucial to closely examine personal values and priorities when applying this model.
