ECON 10A Lecture Notes - Lecture 3: Quasi, Ordinal Utility, Utility
Document Summary
This is the slope of the indi erence curve. Hypothesis of diminishing mrs: the rate at which you are willing to substitute good 1 for good 2 declines as there is more of good 1 and less of good 2. Ordinal utility: numbers are not important and don"t tell rankings, how it orders bundles of goods is the most important. Ex: in written notes (ordinal utility makes most pre ered) U(x , x )= (x , x ) x =k/x . If u(x , x ) is a utility function representing a particular set of preferences, however there are other functions that can represent the same preferences. U(x , x )= 3*min(x , x ) also represent s those same preferences with the same ordering of bundles. Any transformation of one set of numbers into another set of numbers that preserves the order of those numbers.
