There is nothing that plays worse in our culture than seeming to be the stodgy defender of old ideas, no matter how true those ideas may be. Luckily,… - Paul Krugman

Now I’m not saying that Keynes was right about everything, that we should treat The General Theory as a sort of secular bible - the way that Marxists treat Das Kapital. But the essential truth of Keynes’s big idea - that even the most productive economy can fail if consumers and investors spend too little, that the pursuit of sound money and s is sometimes (not always!) folly rather than wisdom - is as evident in today’s world as it was in the 1930s. And in these dangerous days, we ignore or reject that idea at the world economy’s peril.

It’s a great honour to be asked to give this talk, especially because I’m arguably not qualified to do so. I am, after all, not a Keynes , nor any kind of serious intellectual historian. Nor have I spent most of my career doing macroeconomics. Until the late 1990s my contributions to that field were limited to international issues; although I kept up with macro research, I avoided getting into the frontline theoretical and empirical disputes.

By 1980, the work of Feldstein, Boskin, Summers, and others had convinced many economists that U.S. taxes were in fact a significant obstacle to investment. Nor was this all: another major U.S. policy, the Social Security system, was also discouraging saving and investment.
