The work necessary to properly answer this question is a team of 100+ domain experts working for at least 5 years. There's no way you're getting a good answer to this question in a comment thread on a website for programmers. Why even ask that question - what value do you expect out of the responses?

I don't think we live in a video game where you can just spend "research points" to develop new economic systems that somehow magically improve economic productivity and solve complex socio-economical problems?
