Expert Solution
Step 1
Consumer preferences for a collection of products and services are measured using the utility function.
The benefit or satisfaction that consumers obtain is calculated in units called utils, which are abstract and difficult to pinpoint.
If a preference relation is monotonic and convex, it is said to be "well-behaved."
Monotonicity: It is always preferable to have more of any product (i.e. every product is a good, no satiation).
