IB Microeconomics: Monopolistic Competition Assumptions and Short-Run Profit Maximization
Monopolistic competition is a market structure defined by conditions including a large number of firms, free entry and exit, and product differentiation that grants each firm downward-sloping average revenue curves. Profit maximization occurs where marginal revenue equals marginal cost ($MR=MC$), resulting in short-run equilibria characterized by abnormal profit, loss, or normal profit. In the long run, zero economic profits (normal profit) are enforced as a boundary condition due to barriers-free entry and exit, while productive and allocative inefficiencies persist relative to perfect competition models.
