what about them?
profits are 0
price=marginal cost
all costs are variable
optimal allocation of inputs is where marginal rate of technical substitution is equal to the price ratio of the inputs.
In the long run, the equilibrium price and quantity for a perfectly competitive firm are determined by factors such as production costs, market demand, and competition from other firms. The firm will adjust its output level until it reaches a point where marginal cost equals marginal revenue, resulting in an equilibrium price and quantity.

Total Cost
A perfectly competitive firm ensures its profitability in the long run by maximizing efficiency, minimizing costs, and continuously adapting to market conditions to maintain a competitive edge. This includes optimizing production processes, pricing strategies, and staying responsive to changes in demand and competition.
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.

Monopolistically competitive firms are not considered to be perfectly efficient in the long run. This is because they have some degree of market power due to product differentiation, which can lead to higher prices and lower output compared to perfectly competitive markets.
In long-run equilibrium, a competitive firm produces at the level of output where marginal cost (MC) equals marginal revenue (MR), which is also equal to the market price (P). This occurs at the minimum point of the average total cost (ATC) curve, ensuring that the firm earns zero economic profit. At this point, the firm's resources are allocated efficiently, and there is no incentive for firms to enter or exit the market. Thus, the firm operates at an optimal scale in the long run.
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!
Perfectly competitive firms earn profit in the long run by producing goods and services at the lowest possible cost and selling them at a price determined by market forces. In the long run, firms can adjust their production levels and costs to achieve equilibrium where price equals marginal cost, allowing them to earn normal profits.
When perfectly competitive firms in an industry are earning positive economic profits, it attracts new firms to enter the market, increasing competition. This leads to a decrease in prices and profits until they reach a long-term equilibrium where firms earn normal profits. This process ensures the long-term sustainability of the industry by preventing excessive profits and encouraging efficiency.
The long run perfect competition graph shows that in a perfectly competitive market, firms earn zero economic profit in the long run. This indicates that the market is efficient and in equilibrium, with prices equal to costs and resources allocated optimally.
In a perfectly competitive market, the process of entry and exit ends when firms earn zero economic profits in the long run. This occurs when the price equals the minimum average total cost, allowing firms to cover all their costs, including opportunity costs. At this point, there is no incentive for new firms to enter the market, and existing firms will not exit, stabilizing the market equilibrium. Thus, the market reaches a state of long-run equilibrium.
