How would a low cost price leader enforce its leadership through implied threats to a rival?

A low-cost price leader can enforce its leadership by maintaining aggressive pricing strategies that create a perception of sustained low prices, making it clear that any attempt by rivals to raise prices would lead to significant market share loss. By consistently undercutting competitors, the leader implicitly threatens to engage in price wars, forcing rivals to either accept lower profit margins or risk being driven out of the market. This strategy not only deters competitors from pursuing aggressive pricing but also reinforces the leader's dominance in the market.
