Short-run Supply Curve
The short run supply curve for a perfectly competitive firm is the marginal cost (MC) curve at and above the shutdown point. Portions of the marginal cost curve below the shut down point are not part of the SR supply curve because the firm is not producing in that range. Technically the SR supply curve is a discontinuous function composed of the segment of the MC curve at and above minimum of the average variable cost curve and a segment that runs with the vertical axis from the origin to but not including a point "parallel" to minimum average variable costs.
