LONG-RUN EQUILIBRIUM, MONOPOLISTIC COMPETITION: Relative freedom of entry and exit ensures that, in the long run, every firm in a monopolistically competitive industry earns exactly a normal profit, receiving neither an economic profit, nor incurring an economic loss. This result is achieved because entry and exit affects the market supply curve, which affects the overall market price, each firm's demand curve, and the range or prices it can charge. Each firm's demand curve adjusts until the profit-maximizing price is exactly equal to average total cost (both short run and long run).

INJECTIONS-LEAKAGES MODEL A macroeconomic model that balances non-consumption expenditures on production (injections) and non-consumption uses of income (leakages) that is used to identify the equilibrium level of, and analyze disruptions to, aggregate production and income. The injections-leakages model is based on the principles of Keynesian economics and provides an alternative to the standard aggregate expenditures (Keynesian cross) analysis. The three injections included in the model are investment expenditures, government purchases, and exports. The three leakages included in the model are saving, taxes, and imports. Three variations are the two-sector injections-leakages model (or saving-investment model), three-sector injections-leakages model, and four-sector injections-leakages model.
