Consider a simple economy consisting of only four firms. Firm A, a miningenterprise, extracts iron ore. Firm B, a steelmaker, produces steel sheets. Firm C,a carmaker, makes automobiles while Firm D produces automobile tires.In 2009, Firm A extracts 50,000 tons of ore, valued at $200 per ton, usingpreviously existing machinery. Firm B produces 10,000 tons of steel sheets,valued at $3,000 per ton, having bought and used all of the ore produced by FirmA. Firm C manufactured 5,000 vehicles and sold them all to households for$20,000 each, having purchased 8,000 tons of steel sheets from Firm B. Inaddition, Firm C imported 5,000 engines from a foreign subsidiary, each valued at$5,000, and purchased 20,000 tires from Firm D for $100 each. Firm D produced100,000 tires valued at $100 each, but only sold 60,000 tires during 2009. Firm D purchased 2,000 tons of steel sheets from Firm B since all of their tires are steelbelted radials
