Question

If you have the following National Income model,

y = C + I + G + (X - M)

C = 7.4 + 0.25 (Y - T)

T = 1.6 + 0.02Y

Where I = 1.9 trillion dollars, G = 3 trillion dollars, X = 2.1 trillion dollars, M = 2.6 trillion dollars.

[1             0        0.33]    [Y]         [15.73]

0.25        -1       -0.25  .  C     =    -7.4 

0.02         0          -1       T            -1.6

1. What is the determinant of A?

2. = ?

3. What is the $A_{c}$ matrix?

4. What is ?

5. Find C* using $\frac{|A_{c}|}{|A|}$
