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.

SAVING-INVESTMENT MODEL A variation of the Keynesian injections-leakages model that includes the two private sectors, the household sector and the business sector. This variation, more formally termed the two-sector injections-leakages model, captures the interaction between induced saving (and indirectly induced consumption expenditures) and autonomous investment expenditures. This model provides an alternative to the two-sector aggregate expenditures (Keynesian cross) analysis of the macroeconomy, including equilibrium, disequilibrium, and the multiplier. Equilibrium is identified as the intersection between the saving line and the investment line. Two related variations are the three-sector injections-leakages model and the four-sector injections-leakages model.
