TOTAL FACTOR COST CURVE, PERFECT COMPETITION: A curve that graphically represents the relation between total factor cost incurred by a perfectly competitive firm when using a given factor of production to produce a good or service. The total factor cost curve is most important in factor market analysis for the derivation of the marginal factor cost curve.Perfect competition is a market structure with a large number of small participants (buyers and sellers). The good exchanged in the market is identical, regardless of who sells or who buys. Participants have perfect knowledge and perfect mobility into and out of the market. These conditions mean perfectly competitive buyers are price takers, they have no market control and must pay the going market price for all inputs bought. The total factor cost curve reflects the degree of market control held by a firm. For a perfectly competitive firm with no market control hiring inputs under perfect competition, the total factor cost curve is a straight line that emerges from the origin. For firms with market control, including monopsony, oligopsony, or monopsonistic competition, the total factor cost curve increases at an increasing rate. The shape of the total factor cost curve thus indicates the degree of market control possessed by the factor buyer.
The vertical axis measures total factor cost and the horizontal axis measures the quantity of input (workers). Although quantity on this particular graph stops at 10 workers, the nature of perfect competition indicates it could go higher. This curve indicates that if Maggie hires 1 worker, then she pays $10 of total factor cost. Alternatively, if she hires 10 workers, then she pays $100 of total factor cost. Should she hire 100 workers, then she would move well beyond the graph, with $1000 of total factor cost. The "curve" is actually a "straight line" because Maggie is a price taker in the labor market. She pays $10 for each worker whether she hires 1 worker or 10 workers. The constant price is what makes Maggie's total factor cost curve a straight line, and which indicates that Maggie has no market control.
