Answer:
This is an example of price leadership.
Step-by-step explanation:
Price leadership is a type of practice where a firm, most likely a dominant one, sets the price and other firms follow it. It is commonly seen in an oligopoly market.
In an oligopoly market, there are a few firms, these firms are interdependent. A price change by one firm affects its rivals.
Price leadership is of different types.
- Barometric
- Collusive
- Dominant
So when a dominant firm changes its price, the followers have to follow it if we they want to retain their market share.
