I think that one goal is to convince people of the merits of the participatory economy model, and I think that practical applications of the model — to SHOW in tangible terms how it would work — would help greatly in that effort. However, in the thirty years since the introduction of the model, there has been precious little in the way of practical applications of the model.
The closest I can think of is the relative handful of enterprises, mostly in North America, that have explicitly tried to implement the participatory economy model in one degree or another. Unfortunately, nearly all of these enterprises are defunct.
I wonder: How can a participatory economy help people here and now? But as I write this, I wonder further: CAN the model help people in the here and now, in one or another small-scale ways? That’s been difficult to answer. It’s a model of a proposed future economy, not a recipe for a better soup. A participatory economy might not the sort of thing that can be applied to other spheres. Maybe it doesn’t have any practical applications?
Or maybe there are practical applications and we just haven’t found them yet. It reminds me of the (apocryphal) quote about electricity attributed (with no evidence) to Michael Faraday. When supposedly asked what practical use electricity has, Faraday said “someday you can tax it”. The great irony of this quote is that one-sixth of all economic activity on Earth is connected to Faraday’s work; arguably nothing is more practical in our age.
Perhaps the participatory economy model will follow the same path. But in order to advance on that path, we need to advance the conceptual work. MAYBE someone can come up with an idea where there’s a tangible problem in the world, and that’s the question I would like to pose here (if anyone has an answer or an idea): What specific tangible problems in the world here and now can the participatory economy model solve?
