The concentration ratio is a measure used in economics to assess the level of market concentration within a specific industry. It is calculated by summing the market shares of the largest firms in the industry. The concentration ratio provides an indication of the degree of competition within the market, with higher ratios suggesting a more concentrated market and lower ratios indicating a more competitive market. This information is often used by antitrust authorities and regulators to evaluate the potential for anti-competitive behaviour and to determine if any intervention is necessary to promote competition and protect consumer welfare.

The concentration ratio is calculated by summing the market shares of the largest firms in the industry. It can be expressed as a percentage or a ratio.
The concentration ratio is important because it provides insights into the competitiveness of a market. Higher concentration ratios indicate a more concentrated market, which may raise concerns about potential anti-competitive behavior.
Yes, a high concentration ratio can raise antitrust concerns. It may indicate the presence of market power, which can lead to anti-competitive practices such as price fixing, collusion, or monopolistic behavior.
A high concentration ratio itself is not illegal. However, if it leads to anti-competitive behavior or abuse of market power, it can be deemed illegal under antitrust laws.
The consequences of illegal concentration ratios can include fines, penalties, and legal action by regulatory authorities. In some cases, divestitures or structural remedies may be required to restore competition in the market.
In certain cases, if a company’s high concentration ratio is found to be anti-competitive, regulatory authorities may require divestitures or structural remedies to restore competition. However, this decision is typically made on a case-by-case basis.
A low concentration ratio generally indicates a more competitive market with a larger number of firms. This can be beneficial for competition as it allows for greater consumer choice, innovation, and lower prices.
Companies can ensure compliance by regularly monitoring their market share and concentration ratios, avoiding anti-competitive practices, and seeking legal advice to ensure their business practices align with antitrust laws.
