What is hit and run competition
When a firm is earning supernormal profit in a highly contestable market another firm enters and undercuts the incumbent firm. This is the 'hit' While still making supernormal profit the firms continue price competition until normal profit is reached and the firm which enters the market then leaves. This is the run. This is only possible because a contestable market has low barriers to entry and exit.
