Abstract:
A new approach to social justice modelling from viewpoint of equilibrium in a model of coordination of social interests is proposed. The model is based on a concept of social tension function, which is given for each agent in addition to his utility function. A social equilibrium is an efficient society state in which any agent has no social tension. An existence theorem is proved and it is shown that different known results on possibility to realise
several social justice principles, considered by many authors, are corollaries of this theorem under appropriate choice of social tension functions.
