Because for a perfectly competetive firm since the demand curve is perfectly elastic even a slightest price change doesnt add any further demand..so there is no change in marinal revenue also.Since revenue is demand multiplied with cost of unit..the two curves are same.
When Demand is perfectly elastic, Marginal Revenue is identical with price.
Demand = Price = Marginal Cost.
No it does not. Only Perfectly Competitive firms have a horizontal Marginal Cost curve, which is also there demand curve.
Because monopolistically competitive firms have an optimal production allocation at monopoly values: marginal revenue = marginal cost, marking-up to the demand function. When competition is not perfect, marginal revenue does not equal demand but is always below it on a Cartesian plane, so the optimal production value of a monopolistically competitive firm is both less and at a higher price than a perfectly competitive one.
A monopoly produces at a point where marginal revenue equals marginal cost, they don't charge this price, but charge a higher price that corresponds with the demand they face. Therefore they produce less and charge more than a competitive firm that equates the price to marginal cost.

Because in Pure Competition, Demand equals Price, and Price equals Marginal Revenue;hence, Demand equals Marginal revenue.
The pure monopolist's market situation differs from that of a competitive firm in that the monopolist's demand curve is downsloping, causing the marginal-revenue curve to lie below the demand curve. Like the competitive seller, the pure monopolist will maximize profit by equating marginal revenue and marginal cost. Barriers to entry may permit a monopolist to acquire economic profit even in the long run.
AnswerFor a perfectly competitive firm with no market control, the marginal revenue curve is a horizontal line. Because a perfectly competitive firm is a price taker and faces a horizontal demand curve, its marginal revenue curve is also horizontal and coincides with its average revenue (and demand) curve. Yes - what you must remember is that a firm's demand curve in perfect competition is its average revenue curve. Average revenue = price x quantity / quantity = price. The demand curve shows the quantity demanded at varying prices and this is exactly what the average revenue curve will do.Because there are so many sellers in the market, no one firm has enough market power to influence price (if a firm tried to raise price consumers would move to different suppliers; nobody would buy the good), therefore price is determined by industry supply and demand, and a firm can produce any quantity at this price . This means that the firm faces a horizontal average revenue (demand curve) and if average revenue is constant, this means total revenue is increasing at a constant rate, and therefore marginal revenue is constant as well.
An increase in demand in a perfectly competitive market will lead to an increase in revenue for the business. The more they sell the more they will make.
marginal revenue always lies behind the demand curve,and when demand increases marginal revenue also increases.demand curve is used to determine price of a commodity.
Price elasticity of demand is a way to determine marginal revenue. Optimal revenue and, more importantly, optimal profit will occur to the point when marginal revenue = marginal cost, or the price elasticity of demand < 1.
marginal revenue is negative where demand is inelastic
