So the best government/economic book I have read is Taleb's Antifragile. It will go against most of what you have been taught in business school (and probably economics if your teachers were anything like mine) and I believe extremely valuable in pointing out the other side of the coin that is often minimized due to its implications. It does go a bit beyond just government and business but it is extremely original and interesting.

Another suggestion for pure economic history would be Keynes Hayek the clash that defined modern economics. It is very well done.
