What causes firms to act in a way to reduce competition in a market?

Firms may reduce competition in a market to increase their market power and profitability. They might engage in strategies such as forming cartels, engaging in predatory pricing, or acquiring competitors to limit consumer choices and maintain higher prices. Additionally, firms may seek to create barriers to entry, such as through patents or exclusive contracts, to prevent new entrants from challenging their dominance. Ultimately, these actions aim to secure a more favorable market position and enhance long-term financial stability.
