AN INPUT-OUTPUT MODEL FOR A FOUR-SECTOR ECONOMY
The relationship governing the intraindustrial and interindustrial sales and purchases of four basic industries-agriculture(A), manufacturing(M), transportation(T), and energy(E)-of a certain economy is given by the following input-output matrix.
a. How many units of transportation are required to produce
b. How many units of transportation are required to produce
c. Which sector of the economy is least dependent on the cost of energy?
d. Which sector of the economy has the smallest intraindustry purchases (sales)?

- Stock Sales and Purchases Eight hundred fifty stockholders invest in one of three stocks. During any month, 25 of stock A holders move their investment to stock B and 10 to stock C. Of stock B holders, 10 move their investment to stock A. Of stock C holders, 15 move their investment to Stock A and 5 to stock B. Find and interpret the steady state matrix for this situation.arrow_forwardSolving for the Output Matrix A small community includes a farmer, a baker, and a grocer and has the input-output matrix D and external demand matrix E below. FarmerBakerGrocerD=[0.40.50.50.30.00.30.20.20.0]FarmerBakerGrocer and E=[100010001000] Solve for the output matrix X in the equation X=DX+E.arrow_forwardIndustrial System An industrial system has two industries with the input requirements below. (a) To produce 1.00 worth of output, Industry A requires 0.20 of its own product and 0.30 of Industry Bs product. (b) To produce 1.00 worth of output, Industry B requires 0.10 of its own product and 0.50 of Industry As product. Find D, the input-output matrix for this system. Then solve for the output matrix X in the equation X=DX+E, where E is the external demand matrix E=[40,00080,000].arrow_forward
