Macroeconomics, even with all of our computers and with all of our information - is not an exact science and is incapable of being an exact science.
Paul SamuelsonThe sad truth is that it is precisely those who disagree most with the hypothesis of efficient market pricing of stocks, those who pooh-pooh beta analysis and all that, who are least able to understand the analysis needed to test that hypothesis.

Paul SamuelsonOur ideal society finds it essential to put a rent on land as a way of maximizing the total consumption available to the society. ...Pure land rent is in the nature of a 'surplus' which can be taxed heavily without distorting production incentives or efficiency.

Paul SamuelsonEconomists are said to disagree too much but in ways that are too much alike: If eight sleep in the same bed, you can be sure that, like Eskimos, when they turn over, they'll all turn over together.
Paul SamuelsonEven fans of actively managed funds often concede that most other investors would be better off in index funds. But buoyed by abundant self-confidence, these folks aren't about to give up on actively managed funds themselves. A tad delusional? I think so.

The public can't do it.'
