Step-by-Step Analysis
To tackle the problem, we first identify the two utility functions and compute their marginal products.
Option set for MPL (i): 'Increasing' vs 'Constant' vs 'Decreasing' corresponds to how ∂U/∂L changes as L changes holding K fixed.
- If U(i) = L^2 K^2, then MPL(i) = ∂U/∂L = 2L K^2. Holding K fixed, MPL(i) is proportional to L, so as L increases, MPL(i) increases. Therefore, 'Incre......Login to view full explanationLog in for full answers
