Eco – consider a ces production function given by q = (k0.5 + l0.5)2

Q2. Text – B & B, 5th ed. Problem #6.24
Consider a CES production function given by Q = (K0.5 + L0.5)2.
a) Does this production function exhibit increasing, decreasing, or constant returns to scale?
b) Suppose that the production function took the form Q = (100 + K0.5 + L0.5)2. Does this production
function exhibit increasing, decreasing, or constant returns to scale?
