Jim's utility function is u(x, x) = x2. Jerry's utility function is u(x, x) = 1000xx2 +2000. Tammy's utility function is u(x, x) = xx2(1-xx2). Oral's utility function is u(x, x2) = 1/(10+2xx2). Marjoe's utility function is u(x, x2) = x(x2+1000). Pat's utility function is u(x, x) = 0.5x1x2 - 10000. Billy's utility function is u(x, x2) = 1/2. Francis's utility function is u(x, x) = x1x2. = (1) Who has the same preferences as Jim? (2) Who has indifference curves whose general shape is similar to Jim's indifference curves? (3) Explain why the above answers differ.
