Markets and Monopolies
1) Whenever people who are willing to sell a commodity contact people willing to buy it, a market for that commodity is created. 2) Buyers and sellers meet in person, or they may communicate by letter, by phone or through their agents. 3) In a perfect market, communications are easy, buyers and sellers are numerous and competition is completely free. 4) In a perfect market there can be only one price for a given commodity: the lowest price which sellers will accept and the highest which consumers will pay.
