Issues relating to the emergence, persistence and stability of co-operation among social agents of every type are widely regarded as important. They are also analytically difficult and intellectually challenging. This work presents the contribution of game theory to the subject. The problem is examined from differing perspectives, such as: axiomatic bargaining theory; the Nash programme of non-cooperative foundations; game with complete information; repeated and sequential games; bounded rationality methods; evolutionary theory; experimental approaches; and others.
