Step 1: Understanding Utility Theory:
In economics, 'utility' is a concept that represents the satisfaction or benefit a consumer derives from consuming a good or service. There are two main approaches to analyzing utility.
Step 2: Differentiating Cardinal and Ordinal Utility:
Cardinal Utility Analysis: This approach assumes that utility is measurable and quantifiable. It suggests that a consumer can express their satisfaction in absolute, numerical units, often called 'utils'. For example, a consumer can say that they get 10 utils of satisfaction from an apple and 20 utils from a banana, implying the banana provides twice the satisfaction of the apple. Thus, utility is expressed in cardinal numbers (1, 2, 3, etc.).
Ordinal Utility Analysis: This is a more modern approach which posits that utility cannot be measured numerically but can be ranked in order of preference. A consumer can say they prefer a banana to an apple, but they cannot say by how much. Utility is expressed in terms of ranks (1st, 2nd, 3rd, etc.).
Step 3: Final Answer:
Cardinal Utility Analysis is based on the idea that the level of utility can be expressed in numbers.
