A monopoly generally is described as a market structure where there is only one seller in the market. Attributes of this market structure usually include: 1) one seller; 2) perfect information; and 3) high barriers to entry. Provide an original example of a company that you believe to be a monopoly. Provide an explane of a product that you believe this company has a monopoly in producing, and why there are no substitutes for this product (no other company's product competes with this one).
