問題: Consider the utiltiy function U = x^2 + 3y which has MUx = 2x and MUy = 3. The indifference curves for this utility function (A)will have a diminishing marginal rate of substitution of x for y. (B)will have a constant marginal rate of substitution of x for y. (C)will have an increasing marginal rate of substitution of x for y. (D)will be straight lines. 我的想法: 答案為C 這題不了解意思要問的是什麼 所以不會 謝謝 -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 59.127.194.112
