A recommendation written as a question: Have you seen the Ken Burns Prohibition documentary? Quite good and a wealth of info for you guys.

Actual question from someone dabbling in game design for a sim game: how are you guys handling the economic aspects? Price fluctuations, market oversaturation, etc. I'm curious if there's more logic back there than some prng. No hate if it is just prng, I just never find discussion on it for sim games.
