Let us consider the following Cobb-Douglas production function P, =Ao LK2e,
Where P = level of output, L= quantity of labor, K = quantity of capital, and Ao is constant. Brand
B2 are two parameters.
Y,= In(P), B.- In(A), X₁, In(L), X2 = In(K₁),
=
y (Y-Y) X₁ (X₁-X)
X21=(X₂1-X)
The following calculations are given from the data of Real GDP, capital, and labor for 20 years.
Tyx = 1.3474 ,ΣΥx = 2.7115, Σχι=0.6759, Ex=2.6745, ExiX2; = 1.3212
Y = 12.2261, X₁ = 9.3024, X₂ 12.6691
Estimate the regression equation.
Interpret the value of B₁ and B₂
What can you say about the output elasticity with respect to labor and output elasticity of the
capital? Which one is more elastic?
Interpret R² = 0.995080.
What can you conclude about the returns to scale of this economy? And why?
