INCREASING-COST INDUSTRY: A perfectly competitive industry with a positively-sloped long-run industry supply curve that results because expansion of the industry causes higher production cost and resource prices. For an increasing-cost industry the entry of new firms, prompted by an increase in demand, causes the long-run average supply curve of each firm to shift upward, which increases the minimum efficient scale of production.

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.
