Answer:

d. It is best measured using the statistic variance inflation factor (VIF).

Explanation:

Multicollinearity is an important issue in multiple regression model, having many independent/ explanatory variables. Multicollinearity is the situation in which two or more independent variables are highly correlated. It is problematic because it increases the standard error of independent variable coefficient & undermines its statistical significance

Variance Inflation Factor [VIF] is a check & corrective measure of multicollinearity.

VIF as a multicollinearity check : It quantifies the correlation between one explanatory variable with other explanatory variables.VIF = 1 implies there is no multicollinearity (correlation between independent variables); VIF upto 5 implies there is moderate multicollinearity (correlation between independent variables). VIF > 5 implies high multicollinearity (correlation between independent variables)
VIF as a multicollinearity correction : Calculating $Var (\beta j )$ = σ^2 / $[TSS j (1 - R^2j)]$ ; where TSS = total sum of square of variable j , σ^2 = j variance, R^2 j = R^2 from regressing all other independent variable on variable j

An economy is operating with output $300 billion below its natural rate, and fiscal policymakers want to close this recessionary

saw5 [17]

Answer and Explanation:

a. The computation is shown below;

As we know that

Y/G = 1 ÷ (1-MPC)

Here

Y = $300 billion,

MPC = 0.75

So,

300 ÷ G = 1 ÷ 0.25

G = $75

So the government should rise the spending by $75 in order to close out the recessionary gap

So, the government should increase the spending by $30 to close the recessionary gap.
