## ⓘ Utility functions on divisible goods

This page compares the properties of several typical utility functions of divisible goods. These functions are commonly used as examples in consumer theory.

The functions are ordinal utility functions, which means that their properties are invariant under positive monotone transformation. For example, the Cobb–Douglas function could also be written as: w x log ⁡ x + w y log ⁡ y {\displaystyle w_{x}\log {x}+w_{y}\log {y}}. Such functions only become interesting when there are two or more goods with a single good, all monotonically increasing functions are ordinally equivalent.

The utility functions are exemplified for two goods, x {\displaystyle x} and y {\displaystyle y}. p x {\displaystyle p_{x}} and p y {\displaystyle p_{y}} are their prices. w x {\displaystyle w_{x}} and w y {\displaystyle w_{y}} are constant positive parameters and r {\displaystyle r} is another constant parameter. u y {\displaystyle u_{y}} is a utility function of a single commodity y {\displaystyle y}. I {\displaystyle I} is the total income wealth of the consumer.
