Q = f(K,L) K²L²
a) What is the expression for the marginal product of K (capital) at the point (K, L)?
=
b) For small increases in K, holding L constant, does the marginal product of K
increase, decrease or stay constant?
c) What is the marginal product of L (labour)?
d) Using your own words, briefly explain the definition of marginal rate of technical
substitution. Calculate the marginal rate of technical substitution between K and L.
e) Does the production function exhibit increasing, decreasing or constant returns to
scale? Explain your answer.
