Question 5
Suppose we have the PRF represented as the equation
In Y₁ = b + b₂ ln X₁, + b₂ ln X₂, + b² ln X3, +u, u, -iid N(0,0¹)
The corresponding SRF is represented as the equation
In Y, =B₁ + B, In X₁, + B₂ In X₂, + B₂ In X3, + e,
We use sample data and OLS method to get the estimation output
In Y, = 2.03 +0.48 In X₁,-0.35 In X₂ -0.06 In X3
se = (0.10)(0.12) (0.13)
(0.13)
R² = 0.98
In which
Y: is consumption of chicken
X₁,: is real income
X₂, is real price of chicken
X: is real price of beef
se indicates the standard error of the estimated coefficients.
In indicates the logarithm of the variables, for example, In Y,=log(Y).
Questions:
(1) How much is the income elasticity of chicken consumption, and how much is
the own-price elasticity?
(2) Explain the procedure of how to conduct the significant test for b₁.
