The dismal science. It has lots of different ways of explaining how the economic and therefore real world works, but most of them are very wrong a lot of the time.However Krugman has a way of putting across his points in a reasonable clear and concise way. And most of what he says in this book makes sense.The fact that with low inflation and austerity measures in place, the only thing that an economy can do is contract further. That a government spending $1 will generate $1.50 of economic benefit, that light touch regulation will only be ridden rough shod over by the global elite.Lots of sense written in here, cannot see any politician reading it though.
