His list regarding economics also raised my suspicion: anti-corruption, union organization, charter cities,... I couldn't really believe that no one was seriously studying these questions, so here are some results from literally 5 minutes of googling: https://www.tandfonline.com/doi/abs/10.1080/09692291003607834 https://www.tandfonline.com/doi/abs/10.1080/0969229100360783... https://www.jstor.org/stable/2522141 https://www.jstor.org/stable/2522141 https://ideas.repec.org/p/ess/wpaper/id2471.html https://ideas.repec.org/p/ess/wpaper/id2471.html and there are even dedicated Master's degrees for some of those questions: http://www.lse.ac.uk/study-at-lse/Graduate/Degree-programmes-2020/MSc-City-Design-and-Social-Science http://www.lse.ac.uk/study-at-lse/Graduate/Degree-programmes... http://www.lse.ac.uk/study-at-lse/Graduate/Degree-programmes-2020/MSc-Criminal-Justice-Policy http://www.lse.ac.uk/study-at-lse/Graduate/Degree-programmes... conclusion: if you're not an expert on the matter yourself, you should be very careful when claiming that something is under-investigated. maybe it's just harder to come up with useable solutions than you think, and that's why you haven't heard of any. at the very least you should spend 5 minutes to google it. PS: be generally cautious of anyone who writes or talks as if hew was an expert on no less than 10 entirely different disciplines.
