For a Monopoly the Demand Curve?

Monopolies have downward sloping demand curves and downward sloping marginal revenue curves that have the same y-intercept as demand but which are twice as steep. The shape of the curves shows that marginal revenue will always be below demand.

Is the demand curve for a monopoly horizontal?

Pure Monopoly: Demand, Revenue And Costs, Price Determination, Profit Maximization And Loss Minimization. For a seller in a purely competitive market, the demand curve is completely elastic, and, therefore, horizontal in a price-quantity graph.

Is the demand curve for a monopoly elastic?

The monopolist will want to be on the elastic portion of the demand curve, to the left of the midpoint, where marginal revenues are positive. The monopolist will avoid the inelastic portion of the demand curve by decreasing output until MR is positive.
