The market that characterizes the industry in which Forey competes is a market where competition is at its greatest possible level and it is a perfectly competitive market and the reason is because its returns decrease with the entering of new firms, also four-firm concentration ratio and Herfindahl Hirschman index are both quite small, so no one has significant market power to set or even influence the market price. In the short-run Forey Inc’s profit will decrease as more and more new firms enter the market and in the long-run Forey Inc will receive only normal (zero) economic profit.
