Answer:
The output growth rate is 3%.
Explanation:
Use the growth accounting equation as follow
ΔA% = ΔY% - αΔK% - βΔL%
Where
∆A = change in productivity = 2%
∆K = growth in capital =
∆L = growth in labor =
α = elasticity of capital = 0.2
β = elasticity of labor = 0.8
∆Y = change in output = ?
Placing values in the formula
2% = ΔY% - ( 0.2 x 1% ) – ( 0.8 x 1% )
2% = ΔY% - 1%
ΔY% = 2% + 1%
ΔY% = 3%
Hence, the output growth rate is 3%.
