Answer:
oligopoly, pure competition, and monopolistic competition
Explanation:
Answer:
We’ll start with Perfect Competition, also known as Pure Competition. In a perfectly competitive market, you have a whole lot of firms. They all produce exactly the same product. It's very easy to enter and exit the market, and because of these things, the firms take whatever price exists in the market. They have no real control over the price because they're so small and because their goods are the same as all the others. One common example of perfect competition tends to be agricultural markets.
Another type of market structure is Monopolistic Competition. Monopolistic Competition is very similar to Perfect Competition with one important exception, and that is that all the products are a little bit different. This means that there is a good amount of competition between firms in the market. And while you may not tend to make a great amount of economic profit, because your product is a little bit different, you do have a little bit of market power. In this example, think about restaurants or maybe clothing stores. They offer many similar choices, though they DO offer some product differentiation.
A third market structure is Oligopoly. Oligopoly is where you only have a few firms and there is some barrier keeping other firms from entering. In an Oligopoly, it's very important for the firms to pay attention to what the other firms are doing. Theres a lot of strategy that comes into play with these firms, usually in the form of advertising, price differentiation, and product development. For Oligopolies, think about soft drink companies or perhaps computer manufacturers; industries where there's only a few firms competing with each other and they all make products that are pretty similar.
And finally, the least competitive is a Monopoly. A Monopoly is where you only have one firm in that market and there exists some barriers to entry that prevent other firms from competing. Monopolies tend to earn profits without having to worry about competing with other firms. This means- historically- they have not had to worry about keeping prices low or even having to produce goods or services of a high quality. And we say “historically” because laws have been created to prevent monopolies from existing or forming in the U.S. Some prime historic examples that are often taught include Andrew Carnegie’s “Carnegie Steel Company” and John D. Rockefeller’s “Standard Oil Company,” both of which existed in the late 1800s and early 1900s.
