(a) Explain the intuition for convex isoquant curves. (b) Suppose the firm is currently at point A. Making referer to the figure, show that, with respect to A, the firm can produce more output with the same cost or spend less i order to produce the same output level. (c) What is value of marginal rate of technical substitution (MRTS) when the firm chooses an optimal input mix?
