MARSHALLIAN CROSS: The standard market diagram, so beloved by undergraduate economics students, with price measured on the vertical axis and quantity measured on the horizontal axis, that presents the law of demand as a downward-sloping demand curve and the law of supply as an upward-sloping supply curve.

MARGINAL REVENUE CURVE, PERFECT COMPETITION

A curve that graphically represents the relation between the marginal revenue received by a perfectly competitive firm for selling its output and the quantity of output sold. 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. A perfectly competitive firm maximizes profit by producing the quantity of output found at the intersection of the marginal revenue curve and marginal cost curve.
