1) Labor Input = 100 million worker hours / year
Capital Input = $ 20 billion
Exponent α = 0.65
Total Factor Productivity, A = 7.5

a) Cobb Douglas production function is of the form
y=kα
Y=AKαL1-α
=7.5*200.65*1000.35
=$263.47 billion
$ share of capital in output = 0.65*$263.47 = $171.26 billion
$ share of Labour in output = 0.35*$263.47 = $92.21 billion
b) Labour = 120 million worker hours per million
Y=AKαL1-α
=7.5*200.65*1200.35
=$280.83 million
$ share of capital in output = 0.65*$280.83 = $182.54 billion (increases)
$ share of Labour in output = 0.35*$280.83 = $98.29 billion (increases)
