Equity Theory
This theory proposes that individuals measure their out- comes/input ratio. Equity theory distinguish that inspiration is not the outcome of an absolute calculation but is a relative calculation. If they calculate that others are getting more outcomes (salary, success) for the same input (effort) they perceive in equality. When people perceive an imbalance in their out- come/input ratio, tension is build up which gives a basis for motivation as people strive for perceived equity and fairness. Based on equity theory in conditions of perceived inequity employees can be predicted to make one of various choices. They can change their inputs (decrease effort), they can change their output (increase productivity), or reframe the conditions (distorting perceptions by changing referent other). Equity theory is not restricted to finance. It has been shown that job titles as well as office space and selection for project groups may also function as outcomes for some employees in their equity equation.
