The names of the companies listed in Dow 30 groups are among the biggest companies in the world and make it well in their industry. Considering the case of the Coca-Cola Company, which is one among the 30 companies in Dow 30, it is notable that it falls in the monopoly industry.Some people mistake a monopoly firm as a firm, which is the sole producer in the economy. However, a monopoly type of an industry is one in which there is a single firm that dominates the industry. The dominating firm sets the prices and makes it very difficult for other firms to enter the economy. By taking the greatest part of the market share, other firms in the industry are left with only a small part of the market share, which they have to share (McKenzie, & Lee, 2008).
