LONG-RUN MARGINAL COST: The change in the long-run total cost of producing a good or service resulting from a change in the quantity of output produced. Like all marginals, long-run marginal cost is the increment in the corresponding total. What's most notable about long-run marginal cost, however, is that we are operating in the long run. Unlike the short run, in which at least one input is fixed, there are no fixed inputs in the long run. As such, there is only variable cost. This means that long-run marginal cost is the result of changes in the cost of all inputs.

INJECTIONS

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