On the Theory of Effective Demand Under Stochastic-Rationing
Abstract The concept of effective demand under stochastic manipulable quantity rationing is shown to be compatible with the existence of nontrivial equilibrium. It is argued that stochastic rationing is unavoidable for any satisfactory definition of effective demand. Moreover, manipulability of the rationing mechanism is necessary for reasons of logical consistency, at least if the distribution over realisations for each agent depends on his own action and on the aggregate values of demand and supply only. In that case, anonymous stochastic rationing schemes reduce to those random functions, the mean value function of which is the uniform proportional rationing mechanism.
