Are macroeconomical questions allowed here? If not, which SE site would be the best for it?
I would say that Macro-economics questions can easily become very broad and hard to answer without making a lot of wild assumptions. This would then turn to pure speculation without, in my opinion, any clear answer to the member asking nor to the rest of the community. Thanks.
I think that macroeconomics can be as well considered from a quantitative perspective - moreover, pure quant researchers like Doyne Farmer are focusing their efforts into improving standard Dynamic Stochastic General Equilibrium models computationally by using Agent-Based Models; I haven't read anything about them on QFStackExchange, but these are topics definitely worth discussing.
