Perfect Competition Shutdown Price and Break-Even Price in IB Microeconomics HL

In IB Microeconomics HL, perfectly competitive firms in the short run cease production (shut down) when price falls to average variable cost and break even in the long run when price equals average total cost, ensuring all opportunity costs are covered. Theoretical analysis demonstrates that such markets achieve allocative efficiency whenever marginal cost equals price or average revenue at the profit-maximizing output level. Furthermore, productive efficiency is attained exclusively in the long-run equilibrium where the intersection of marginal and average cost curves minimizes production expenses while simultaneously satisfying allocative conditions.
