Mathematical Economics Specialist Response:
"To solve for the production vector X using the input-output model X = (I - A)^(-1) * F:
The identity matrix I is:
[[1, 0], [0, 1]].
Compute (I - A):
I - A = [[1, 0], [0, 1]] - [[0.2, 0.1], [0.3, 0.4]] = [[0.8, -0.1], [-0.3, 0.6]].
Find the inverse of (I - A):
(I - A)^(-1) = 1 / (0.8 * 0.6 - (-0.1) * (-0.3)) * [[0.6, 0.1], [0.3, 0.8]].
Simplify to get: [[1.25, 0.25], [0.625, 1.25]].
Multiply by F to get X:
X = [[1.25, 0.25], [0.625, 1.25]] * [100, 200] = [175, 312.5].
