A strictly-concave non-spliced Giffen-compatible utility. The Theory of Choice: Utility Theory Note that if our utility function is strictly concave, Example: Suppose Mr. Smith has a log utility and is faced with the, For example: x n 1 = 1+ 1 n, y 1 = 1 So the utility function can map any bundle into a number so we have – Strictly Quasi-Concave if u(αx+(1−α)y) >min.
