It seems there might be a typo in your question, as "eligopoly" does not appear to be a recognized term in economics or other fields. If you meant "oligopoly," it refers to a market structure characterized by a small number of firms that dominate the market. These firms have significant market power and may engage in strategic decision-making regarding pricing, output, and other competitive factors. If you meant something else, please clarify, and I would be happy to help!
