Detailed explanation-1: -A monopoly is a firm who is the sole seller of its product, and where there are no close substitutes. An unregulated monopoly has market power and can influence prices. Examples: Microsoft and Windows, DeBeers and diamonds, your local natural gas company.
Detailed explanation-2: -These spillover costs and benefits are called externalities. A negative externality occurs when a cost spills over. A positive externality occurs when a benefit spills over. So, externalities occur when some of the costs or benefits of a transaction fall on someone other than the producer or the consumer.
Detailed explanation-3: -Pure Monopoly This firm is the sole producer of a product, and there are no close substitutes. Because there are no alternatives, the firm has the highest level of market power. Hence, monopolists often reduce output, increase prices and earn more profit. Entry or exit is blocked in a pure monopoly.
