"Economics is not an exact science. It's a combination of an art and elements of science. And that's almost the first and last lesson to be learned about economics: that in my judgment, we are not converging toward exactitude, but we're improving our data bases and our ways of reasoning about them."
Paul Samuelson"Good questions outrank easy answers."
Paul Samuelson"Economics has never been a science - and it is even less now than a few years ago."
Paul Samuelson"Economics is a choice between alternatives all the time. Those are the trade-offs."
Paul Samuelson
