maximizing the difference between total revenue and total cost
is producing where price exceeds marginal costs
At the output level at which the slopes of the total revenue and total cost curves are equal, provided the firm is covering its variable cost
When variable costs rise in a perfectly competitive industry, profits will decrease and output levels may decrease as well. This is because higher variable costs reduce the profit margins for firms, leading to lower overall profits. In response, firms may reduce their output levels to maintain profitability.
if competative industry z is making substantial economic profit, output will:
A perfectly competitive firm will not earn an economic profit in the long run because in a perfectly competitive market, there are many firms selling identical products, leading to price competition. This competition drives prices down to the point where firms only earn enough revenue to cover their costs, resulting in zero economic profit.
The monopolist's profit maximizing level of output is found by equating its marginal revenue with its marginal cost, which is the same profit maximizing condition that a perfectly competitive firm uses to determine its equilibrium level of output. Indeed, the condition that marginal revenue equal marginal cost is used to determine the profit maximizing level of output of every firm, regardless of the market structure in which the firm is operating.

is earning a profit
To increase profit the firm will decrease output to a point where MC=MR. This is the Profit Maximisation point
In perfectly competitive markets, economic profits are zero in the long run because firms are able to enter and exit the market. If firms in a perfectly competitive market are profitable, there would be an incentive for new firms to enter. Supply would increase, causing an increase in quantity and the price to be driven back down to equilibrium: NO PROFIT! If firms in a perfectly competitive market are suffering a loss, some firms would choose to exit the market. Supply would decrease, causing a decrease in quantity and the price to be driven back up to equilibrium: NO PROFIT!
I agree with the statement. A perfectly competitive firm operates where price equals marginal cost, leading to an efficient allocation of resources and typically resulting in a higher output at a lower price than a monopoly. In contrast, a single-price monopoly maximizes profit by producing less output and charging a higher price, leading to decreased consumer surplus and potential market inefficiencies. Thus, perfect competition generally results in greater output and lower prices compared to monopoly scenarios.
