Question:

A firm produces two products, X and Y. The production technology displays the following costs, where C (i, j) represents the cost of producing i units of X and j units of Y: C(0, 50) = 100 C(5, 0) = 150 C(0, 100) = 210 C(10, 0) = 320 C(5, 50) = 240 C(10, 100) = 500. Does this production technology display economies of scale? Of scope?
