Question 33 XYZ Corp. produces 1,000 units of output (along the same isoquant) using various combinations of capital (K) and labor (L). At point A (along the same isoquant), the firm uses 30 units of capital and 3 units of labor. When it moves to point B (along the same isoquant), it uses 12 units of cap labor. Based on this information, the firm's elasticity of input substition ( o) is? Hint: You may want to draw a graph of the firm's isoquant and identify points A and B (and their corresponding K/L combinations). O a. 1 O b. co (positive infinity) O c. O d. 5
