Determine whether the following production functions have Constant, Decreasing or Increasing Returns… Show more Determine whether the following production functions have Constant, Decreasing or Increasing Returns to Scale (a formal proof is required). (a) F (K,L)= K^3+L^3 (b) F (K,L)= K^2/L^3 (c) F(K,L)= 2K^2+3L^2/ K+L (d)F(K,L)=K^aL^1-a (where “a” is a parameter) • Show less
