Here’s the utility function \hat u (x_1,x_2) = 2\sqrt {x_1x_2} u(x1,x2) = 2 x1x2 plotted, along with its indifference map. We can see that it produces a lot more “utils” from the left-hand graph than the figure above, but the indifference curve through any given point is exacty the same: 0 20 40 60 80 0 20 40 60 80.
It is the marginal utility of the good divided by its price. The utility gained by spending an additional dollar on good X, for example, is. M U x P x M U x P x. This additional utility is the marginal benefit of spending another $1 on the good. Suppose that the marginal utility of good X is 4 and that its price is $2.
Consumers have a preference for diversity in consumption. Consumers value more the first unit of any good they own, compared to the hundredth unit. Everyone gets tired of consuming the same thing eventually. These are all appropriate ways to capture the intuition behind the principle of diminishing marginal utility.

Examples of utility functions. While economists use a wide range of utility functions, we’ll be interested in two main classes of functional forms in this course. Utility functions for analyzing complements and substitutes. One of the key aspects of a utility function is how it describes the relationship between the goods it’s modeling:
