Agent based modeling (ABM) is an attempt at this. I've wanted to forecast the economy on a per-person basis since playing Sim City as a kid (although Sim City is not an ABM to be clear). From doing a bit of research a while back it seemed like the research and real world forecasting have been done on a pretty small scale and nothing as grand as I'd hoped. It's been a while since I've looked into so I would be happy to be corrected.
