LONG-RUN PRODUCTION: An analysis of the production decision made by a firm in the long run. The central feature of this long-run analysis is returns to scale, which results in the long run even though all inputs are variable. Returns to scale are reflected in the long-run average cost curve as either economies to scale or diseconomies to scale.

INJECTION: A non-consumption expenditure on gross domestic product, including investment expenditures, government purchases, and exports. Injections are combined with leakages in the injection-leakage model used to identify equilibrium aggregate output in Keynesian economics. The notion of injection is best viewed through the circular flow, in which investment expenditures, government purchases, and exports are "injected" into the main flow between output, factor payments, national income, and consumption.
