Is the following statement true or false? Briefly explain your answer. "Two consumers with utility functions of U(x,y)=x.y and V(x,y)=1/2ln(x)+1/2ln(y), respectively, have different preferences and therefore would rank baskets of goods x and y differently from each other.

Solutions

Expert Solution

Two different utility functions show same preferences if their respective MRS are same.

U = xy

MRS of U = MUx/MUy = (y/x) ----equation 1

V = 0.5lnx + 0.5lny

MRS of V = MUx/MUy = (0.5/x) / (0.5/y)

MRS of V = (y/x) ------equation 2

Using equation 1 and 2

MRS of U = MRS of V

Hence, the preferences are same and not different.

So, Statement is FALSE
