9-1 Horrible Harry's Horrible Harry's is a chain of 47 self service gas stations served by a small refinery and mixing plant. Each day's product requirements are met by blending feedstocks on hand at midnight. The volumes vary daily, depending on the previous day's refinery output and on bulk receipts. The entire operation is run by the owner, Harry Oldaker. Although dozens of chemicals and byproducts are generated by the refinery, Harry's major concern is the retail distribution of gasoline products. On a particular Tuesday there are sufficient volumes of leaded and unleaded regular gasoline's at the stations. Only the two hybrid petroleum products- gasohol and petrolmeth- will b... click for more

Linear Algebra- Leontief Input-Output Model

1. Why did Leontief use linear algebra techniques to create his model? Can you think of alternative methods? 2. What are the main strengths of his model? 3. Does it have any limitations (that you can think of)? 4. How might the Input-Output model be useful in the real world? (In other words, would anyone except an Economist be interested in the results?)
