Assume that two clothing manufacturers, Tosin and Bimbo, market their goods strictly by mail order. Each produces an essentially identical field coat. The cost of producing such a coat is exactly $100. Because the field coats are perfect substitutes, customers will flock to the seller that offers the lowest price. If both firms offer identical prices, each receives half the customers. Assume that the two firms have the choice of pricing at whole-dollar prices of $103, $102, or $101. Market demand at $103 is 100 coats; at $102, 110 coats; and at $101, 120 coats
