The ordinal approach to utility is based on the idea that individuals can rank their preferences for different goods and services, but they cannot assign specific numerical values to these preferences. In other words, individuals can say that they prefer one good over another, but they cannot say by how much. This approach focuses on the relative ranking of preferences rather than the absolute magnitude of those preferences.
On the other hand, the cardinal approach to utility allows individuals to assign specific numerical values to their preferences for different goods and services. This approach assumes that individuals can quantify their preferences and make decisions based on these quantified values. In other words, individuals can say not only that they prefer one good over another, but also by how much they prefer it.
In summary, the ordinal approach to utility focuses on the ranking of preferences without assigning specific numerical values, while the cardinal approach allows individuals to assign specific numerical values to their preferences.

Ordinal Approach to Utility
- Focuses on ranking preferences: Assumes that individuals can rank alternatives in order of preference, but it does not quantify the differences between these preferences.
- Uses ordinal numbers: Assigns numerical values (usually 1, 2, 3, etc.) to represent the rankings, with higher numbers indicating higher preferences.
- Preserves preference orderings: The assigned numbers only reflect the relative ordering of preferences, not the actual intensity of preferences.
- Example: You prefer ice cream over chocolate and chocolate over vanilla. Using the ordinal approach, ice cream gets a higher numerical value (e.g., 3) than chocolate (2) and chocolate gets a higher value than vanilla (1).
Cardinal Approach to Utility
- Quantifies utility differences: Assumes that individuals can not only rank preferences but also measure the intensity of their preferences.
- Uses cardinal numbers: Assigns numerical values to represent the actual strength of preferences, with higher numbers indicating greater utility.
- Preserves both ordering and intensity: Not only does it preserve the preference orderings, but it also accurately reflects the magnitude of the differences in preferences.
- Example: Using the cardinal approach, you might assign an absolute value of 100 to your preference for ice cream, 70 to your preference for chocolate, and 40 to your preference for vanilla.
Key Differences:
| Feature | Ordinal Approach | Cardinal Approach |
|---|---|---|
| Ranking | Yes | Yes |
| Quantification of preferences | No | Yes |
| Preservation of preference order | Yes | Yes |
| Preservation of intensity differences | No | Yes |
| Numerical values | Ordinal numbers | Cardinal numbers |
Applications:
- Ordinal approach: Used in situations where only preference rankings are required, such as voting or consumer surveys.
- Cardinal approach: Used when the intensity of preferences is important, such as in economic modeling, cost-benefit analysis, or assessing the value of public goods.
