D Question 14 1 pts (*) In the Cobb-Douglas production function y = AK0.4 10.6 , labor's share of GDP is O 4/6 O always equal to 1 O 40% regardless of how much labor there is O 40% but can change as more workers are added O 60%, regardless of how much labor there is D Question 15 1 pts (*) Suppose the production function takes the form Y = AKL1-a, and we measure income differences between two countries by A = In(yrich ) - In(ypoor ), where yrich is per capita GDP of the rich country and ypoor per capita GDP of the poor country. Assuming the two countries have the same productivity, then A is equal to (1 - a) In(krich + kpoor) . a (In(krich ) - In(kpoor )) In(krich -kpoor) . (1 - a) (In(krich ) + In(Kpoor)) O In(krich ) In(kpoor)
