What is the Difference Between Cardinal and Ordinal Utility?

🆚 Go to Comparative Table 🆚

The main difference between cardinal and ordinal utility lies in how they measure and compare the satisfaction or benefit that individuals derive from consuming goods or services. Here are the key differences between the two concepts:

  1. Measurement: Cardinal utility measures the satisfaction level in utils, which are numerical units representing the amount of satisfaction derived from consuming a good or service. On the other hand, ordinal utility ranks the satisfaction level in the order of preference, without assigning numerical values to the utility.
  2. Quantitative vs. Qualitative: Cardinal utility is quantitative, allowing for precise measurement and comparison of utility. Ordinal utility, however, is qualitative and emphasizes the ranking of preferences without numerical quantification.
  3. Interpersonal Comparison: Cardinal utility assumes that interpersonal comparison of utility is possible, meaning that one individual's satisfaction can be compared to another's. Ordinal utility does not make this assumption, focusing instead on individual preferences.
  4. Realism: Ordinal utility is considered more realistic as it is based on qualitative measurement and does not require numerical assignment to utility. Cardinal utility, which relies on numerical values, is considered less realistic.
  5. Analysis: In the context of consumer behavior, cardinal utility is analyzed using marginal utility analysis, while ordinal utility is analyzed using indifference curve analysis.

In summary, cardinal utility focuses on assigning numerical values to utility and allowing for precise measurement and comparison, while ordinal utility emphasizes the ranking of preferences without numerical quantification. Each approach has its advantages and disadvantages, and their relevance depends on the specific context and research objectives.

Comparative Table: Cardinal vs Ordinal Utility

The main difference between cardinal and ordinal utility lies in how they measure the satisfaction a consumer derives from consuming a good or service. Here is a table comparing the two concepts:

Feature Cardinal Utility Ordinal Utility
Meaning Refers to the utility where the satisfaction from consuming goods or services can be scaled in numerical terms (utils). Refers to the utility where the satisfaction from consuming goods or services cannot be scaled in numerical terms, but can be ranked in terms of preference.
Measurement Objective and quantitative. Subjective and qualitative.
Realism Less realistic, as quantitative measurement of utility is not possible. More realistic, as it relies on qualitative measurement.
Approach Based on marginal utility evaluation. Preferred more because it provides more robust results.
History Presented by Alfred Marshall and his admirers. Pioneered by John Hicks and R.J. Allen.

Both cardinal and ordinal utility are essential for assessing and analyzing consumer demand for goods or services. While cardinal utility measures the utility objectively, ordinal utility measures it subjectively based on the ranking of preferences for commodities.
