A feature of participatory planning which differs from other modes of democratic planning is that all deliberation on proposals occurs within councils, but does not take place between councils. That is, under parecon, a feasible economic plan is constructed due to an iterative adjustment of prices (participatory planning) based on councils' self-activity proposals, rather than owing to a procedure of deliberation among delegates across workplaces/industries. This is potentially desirable by cutting down on the meeting time and bureaucratic burdens needed to converge on an annual plan.
