Consider the following utility function belonging to “Consumer A”. UA(x,y,z,v) = x0.1y0.2z0.3v0.4. Suppose that prices of x, y, z and v are 1$, 2$, 3$ and 4$. The consumer’s income is 10$. a. Find the values of x, y,z and v that maximize the consumer’s utility subject to his/her budget constraint. b. Suppose that “Consumer B” has a utility function which is a logarithmic transformation of the consumer A’s utility function, i.e.  UB =ln UA. Suppose that prices and income are the same. Would the amounts of x, y, z and v consumed by “Consumer B” be the same as the amounts consumed by “Consumer A”?

Question

Consider the following utility function belonging to “Consumer A”.

UA(x,y,z,v) = x0.1y0.2z0.3v0.4.

Suppose that prices of x, y, z and v are 1$, 2$, 3$ and 4$. The consumer’s income is 10$.

a. Find the values of x, y,z and v that maximize the consumer’s utility subject to his/her budget constraint.

b. Suppose that “Consumer B” has a utility function which is a logarithmic transformation of the consumer A’s utility function, i.e.

 UB =ln UA.

Suppose that prices and income are the same. Would the amounts of x, y, z and v consumed by “Consumer B” be the same as the amounts consumed by “Consumer A”?
