Specifically, the steeper the demand curve is, the more a producer must lower his price to increase the amount that consumers are willing and able to buy, and vice versa. Graphically, the marginal revenue curve is always below the demand curve when the demand curve is downward sloping because, when a producer has to lower his price to sell more of an item, marginal revenue is less than price. In the special case of a perfectly competitive market, a producer faces a perfectly elastic demand curve and therefore doesn't have to lower its price to sell more output.
