ABSTRACT
An important advance in theories of social justice is the development of models of distributive justice. The first model of distributive justice is equity theory. It originally develops in the context of work organizations to explain workers' reactions to the wages. The basic justice principle underlying equity theory is a balance between contributions and rewards. The findings, support the basic equity theory prediction. Equity research also demonstrates that other measures besides equity are relates to feelings of satisfaction, suggesting that people are not completely equity orients. The application of equity theory to policymaking highlights the important role of societal and/or cultural rules in specifying appropriate or in–appropriate inputs. The nature of the interdependence underlying the relationship between people influences the choice of justice criteria. The resource theory typology is important to equity theory and distributive justice research for several reasons. Reciprocal Causation analysis has presents the structure of relationships as shaping the choice of justice principles uses.
