This is one area I can’t get my head around, given the current level of technology. Is there now any need in parecon for individuals (or households or neighbourhoods that are also very small units) to list their future personal consumption needs at all, even if only coarse categories or changes in quantities?
Amazon, for example, is already good at forecasting future demand based on product histories. And it will only get better with AI. The problem in a market economy isn’t the way Amazon does it, but that there are competing retailers or producers. Amazon can forecast some level of aggregate demand for coffee or kettles, but knows little about coffee or kettles bought from other places. So need ‘national data’ or ‘one big Amazon’.
Wouldn’t this be sufficient in a future society? Leaving consumer input only for things such as new products and occasional big ticket products.
Lastly, and on the other hand, it does feel awkward to take humans out of the needs discovery process.
(I’m only thinking about personal consumption, not public consumption or the allocation of ‘capital’ and labour in production.)
