Unformatted text preview: of x . Whats left over goes to external demand. Thus, we have the Leontief equation x = Ax + d. Since it takes 0.3 units of steel and 0.2 units of coal to produce one unit of steel, we have that . 3 . 2 = a 11 a 12 a 21 a 22 1 = a 11 a 21 . Similarily, since it takes 0.1 units of steel and 0.6 units of coal to produce one unit of coal, we have that . 1 . 6 = a 11 a 12 a 21 a 22 1 = a 12 a 22 . Thus, we have that A = . 3 0 . 1 . 2 0 . 6 ....
