SHORT-RUN SUPPLY CURVE: For a perfectly competitive firm, the marginal cost curve that lies above the average variable cost curve. This segment of the marginal cost guides a perfectly competitive firm's profit maximizing production as it equates price to marginal cost. Because the marginal cost curve is positively sloped (due to the law of diminishing marginal returns), each firm's supply curve and the market supply curve are also positively sloped. The law of diminishing marginal returns thus provides an explanation for the law of supply. However, this only works for firms with NO market control. Monopoly, monopolistic competition, and oligopoly, with market control, do not achieve the same result.

PERFECTLY INELASTIC An elasticity alternative in which changes in one variable (usually price) do NOT cause any changes in another variable (usually quantity). Quantity is totally, completely unresponsive to price. Quantity just does not change, regardless of changes in price. This characterization of elasticity is most important for the price elasticity of demand and the price elasticity of supply. Perfectly inelastic is one of five elasticity alternatives. The other four are perfectly elastic, relatively elastic, relatively inelastic, and unit elastic.
