LRAC CURVE: The common abbreviation for the long-run average cost curve, which is a curve depicting the per unit cost of producing a good or service in the long run when all inputs are variable. The long-run average cost curve can be derived in two ways. On is to plot long-run average cost, which is, long-run total cost divided by the quantity of output produced. at different output levels. The more common method, however, is as an envelope of an infinite number of short-run average total cost curves. Such an envelope is base on identifying the point on each short-run average total cost curve that provides the lowest possible average cost for each quantity of output. The long-run average cost curve is U-shaped, reflecting economies of scale (or increasing returns to scale) when negatively-sloped and diseconomies of scale (or decreasing returns to scale) when positively sloped. The minimum point (or range) on the LRAC curve is the minimum efficient scale.

Evaluation: Don't Agree

The data and hypothesis don't agree.- While we can never absolutely prove a universal positive, we can disprove it, we can reject it as false.
- Rejecting an hypothesis can be as useful and as informative than accepting it. We know something that is NOT true.
- If an hypothesis is wrong, then maybe the theory is wrong. Maybe the previously verified principles, unverifiable world axioms are wrong. Maybe the specific test was bad.
- Whether an hypothesis is accepted or rejected, the recommendation is to do another test and another
Remember science is a process, not a subject.

LEAKAGES Non-consumption uses of aggregate income. The three uses of income grouped under the heading of leakages are saving, taxes, and imports. Leakages subtract from the core circular flow containing consumption, production, and income. The injections-leakages model is a Keynesian economics analysis that combines leakages with injections (investment expenditures, government purchases and exports) to identify the equilibrium level of aggregate production and income.
