Term factor market equilibrium Definition: Equilibrium in the factor market, which for a perfectly competitive market is achieved at the factor price and factor quantity give by the intersection of the factor demand curve and the factor supply curve. For factor markets that are not perfectly competitive, such as those controlled by monopoly or monopsony, factor market equilibrium is achieved when the controlling firm maximizes profit. For monopoly, this is the factor quantity that equates marginal revenue and marginal cost. For monopsony, this is the factor quantity that equates marginal revenue product with marginal factor cost. But regardless of marginal structure, as an equilibrium it is maintained until shocked by an external force.
