INJECTION LINE: A line used in the injection-leakage model representing the relation between non-consumption expenditures (that is, injections) and national income. The three injections are investment expenditures, government purchases, and exports. The foundation of the injection line is the investment line, which is then enhanced by adding government purchases and exports. The other part of the injection-leakage model is a line representing leakages. The intersection of the injection and leakage lines identifies equilibrium aggregate output, or Keynesian equilibrium.

ARC ELASTICITY The average elasticity for discrete changes in two variables. The distinguishing characteristic of arc elasticity is that percentage changes are calculated based on the average of initial and ending values of each variable, rather than initial values. Arc elasticity is generally calculated using the midpoint elasticity formula. The contrast to arc elasticity is point elasticity. For infinitesimally small changes in two variables, arc elasticity is the same as point elasticity.
