market power & deadweight loss
Controls
Presets
A monopolist maximizes profit where marginal revenue equals marginal cost — then charges the price the demand curve allows. Because MR lies below demand, the monopoly produces less and charges more than a competitive market (where price equals MC). The red triangle is the deadweight loss: mutually beneficial trades that never happen.

Governing equation
Reading this result: At MC = $30, the monopolist makes 35 units and charges $65 — a $35 markup over cost. That output is exactly half the competitive 70, and the shaded triangle (613) is the welfare lost to that restraint.
