MEDIATION: Intervention by an impartial third party to settle disputes between two others. The actions of this third party--the mediator--are not legally binding. Mediators are frequently used in collective bargaining negotiations when unions and their employers have reached an impasse. Mediators help both sides work out a satisfactory agreement. But neither side is legally compelled to follow the mediator's advice.

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.
