A perfectly competitive firm would set its prices at a perfectly competitive price.
a perfectly competitive firms supply curve will be the portion of the marginal cost curve which lies above the average variable cost curve (AVC)..this will be due to the firms unwillingness to supply below the price in which they could cover their variable costs
A perfectly competitive firm's supply curve is that portion of its' marginal cost curve that lies above the minimum of the average variable cost curve. A perfectly competitive firm maximizes profit by producing the quantity of output that equates price and marginal cost. As such, the firm moves along it's marginal cost curve in response to alternative prices. Because the marginal cost curve is positively sloped due to the law of diminishing marginal returns, the firm's supply curve is also positively sloped.
Because of the price taking nature of the firm in the perfectly competitive market. The supply curve would be the portin of the (Marginal Cost Curve) that disects the (P=Ar=Mr curves). Som from that point up would be the supply curve, to produce below that point would not be beneficial to the establishment. Up sloping and equal to the portion of the marginal cost curve that lies above the average variable cost. The demand curve is also perfectly elastic, this too contributes to the fact.

The marginal product is the output produced by one more unit of a given input. Found at http://www.econmodel.com/classic/terms/marginal_product.htm

If an individual in a perfectly competitive firm charges a price above the industry equilibrium price this is bad. This company will go out of business quickly because their customers will go find the lower price.

Yes, it is generally inevitable that the monopoly price is higher than the competitive price. In a competitive market, many firms offer similar products, driving prices down to the marginal cost of production. In contrast, a monopolist, being the sole producer, can set prices above marginal cost by restricting output to maximize profit. Graphically, this is illustrated by a downward-sloping demand curve for the monopolist, which shows that as the monopolist raises the price, the quantity demanded decreases, leading to higher prices compared to the horizontal demand curve in perfect competition.
No, monopolists are not price takers like competitive firms. In a competitive market, firms accept the market price as given and cannot influence it due to many competitors. In contrast, a monopolist has market power and can set prices above marginal cost, as they are the sole supplier of a good or service, allowing them to influence the market price.
I'm thinking that marginal revenue product is the marginal revenue on one product, and marginal revenue is the marginal revenue on the whole firm sales... I'm wondering the same thing but the above response is incorrect. both terms imply values on one item as indicated by the "marginal"
Marginal cost curve above the average variable cost curve, is the same as the short run supply curve. In perfect competition, MC=Price. It follows that production will be at that point. Hence the supply curve is the same as that part of the MC curve which is above AVC, where the firm can cover its variable cost....this is better than shutting down.
It is possible for perfectly competitive markets to be inefficient when externalities are present. Externalities arise when an economic activity has an unintended impact on other economic agents and/or the market. This results in there being a socially optimal level of production that does not coincide with the privately determined equilibirum level of production derived from the supply and demand curves (which, respectively, represent the marginal private costs and marginal private benefits to producers and consumers). With respect to the efficiency of markets, positive externalities result in too little of the good in question being produced. In this case, the market equilibrium is lower than desired (the marginal social benefit curve lies above the marginal private benefit [demand] curve). In this case, the efficient market outcome would occur where the marginal social beneift curve interests the marginal private cost (supply) curve. When negative externalities occur, too much of the good in question is being produced. This results in the supply curve, which represents the marginal private costs of production, lying below the marginal social cost curve because the private cost curve fails to take into account the costs of production incurred by all of society. In this case, the efficient market outcome would occur where the marginal social cost curve coincides with the private marginal benefit (demand) curve.
