The market demand curve of the perfectly competitive industry is downward-sloping while the demand curve facing an individual firm is horizontal.
If all firms in an industry form a cartel, they act as a single producer and collude to charge the profit-maximizing price that would be charged by a monopoly.
True

The principle feature of private goods is that
consumption by one person reduces the quantity available to others.
After participating members of a cartel form an agreement on common prices and output quotas, then an individual firm can increase its own profits by
decreasing prices.
For a monopolistically competitive market, the number of firms in the market implies that
each firm acts independently of other firms

must consider the reaction of rival firms when making a pricing or output decision.
When the social costs exceed the private costs, economists state that there is
