Since no participant in the planning procedure enjoys an advantage in influence over any other, and since each participant impacts the valuation of social costs and benefits like all others, but with each having more impact on what they are involved in and less on what they aren't affected by, the procedure generates equity, efficiency, and self management simultaneously. In other words, individuals make proposals for their own private goods consumption. Neighborhood councils make proposals that include approved requests for private goods as well as shared requests for the neighborhood's collective consumption. Higher-level federations make proposals that include approved requests from member councils as well as the federation's collective consumption request. Similarly, each production unit proposes a production plan.
Workplaces enumerate the inputs they want and outputs they propose to make available.
Regional and industry federations aggregate proposals and keep track of excess supply and demand. The attained plan manifests actors' preferences proportionately as they are impacted. More, each actor benefits only insofar as do all others. That is, my income depends directly on the socially average income and my job comfort depends on the quality of the socially average job complex. Solidarity is therefore enhanced by participatory planning because our interests are entwined and our daily economic calculations occur in light of one another's situations.
