PERFECT COMPETITION, SHORT-RUN PRODUCTION ANALYSIS: A perfectly competitive firm produces the profit-maximizing quantity of output that equates marginal revenue and marginal cost. This production level can be identified using total revenue and cost, marginal revenue and cost, or profit. Because a perfectly competitive firm faces a perfectly elastic demand curve, it efficiently allocates resources by equating price and marginal cost. In addition, the marginal cost curve above the average variable cost curve is the perfectly competitive firm's short-run supply curve.

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.
