  In [1] we presented a model for transactions when goods are given away in the
expectation of a later settlement. In settings where people keep track of their
social accounts we were able to redefine concepts like account balance, yield
curve and the law of diminishing returns. In this paper we establish a general
equilibrium theorem, conjectured in [1], by developing sufficient conditions
for any instance of the standard model (or Gift Economy Model) to have a unique
equilibrium. The convergence to that equilibrium is exponential and for each
pair of entities P and Q the total sum of yields from all mutual transactions
is equal to zero.
