PERFECT COMPETITION AND SHORT-RUN SUPPLY CURVE: A perfectly competitive firm's supply curve is that portion of its' marginal cost curve that lies above the minimum of the average variable cost curve. A perfectly competitive firm maximizes profit by producing the quantity of output that equates price and marginal cost. As such, the firm moves along it's marginal cost curve in response to alternative prices. Because the marginal cost curve is positively sloped due to the law of diminishing marginal returns, the firm's supply curve is also positively sloped.

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.
