Statement of Question 1
One of the key concepts in production theory is the production function Q = f(L, K) and the corresponding isoquants. The Marginal Rate of Technical Substitution (MRTS) is the ability of the firm to replace capital for labour while maintaining the same output level. Figure 1 shows the isoquant for Q = 100. There are two tangent lines: one at point A = (3, 6) and another at point B = (5, 4). On the isoquant for Q = 100, the slope falls when we move from the input combination A = (3, 6) to B = (5, 4).
Perform the following tasks:
(a) Calculate the value of the MRTS at points A and B. [10 marks]
(b) What is incorrect in the Statement of Question 1? [10 marks]
