Price Rigidity:
The other significant feature of oligopoly is price rigidity. Price is rigid or sticky at the prevailing level due to the fear of reaction from the rival firms. When an oligopolistic firm lowers its price, the price reduction will be followed by rival firms. As an outcome, the firm loses its profit. Expecting similar kind of reaction, when the oligopolistic firm increases the price, the rival firms will not pursue. This would outcome in losing customers. In both manners the firm would face difficulties. Thus the price is rigid.
