Two cheers for Paul Krugman

Paul Krugman says that this (from this Branco Milanovic paper) gives you recent history in one chart, and it's hard to disagree: 010115krugman1-tmagArticle

Everyone got richer in real terms, although some a lot more than others – and this doesn't fully include technological developments that make pocket supercomputers cheap enough that even people on quite low incomes (for rich countries) can afford them. Like Scott I am more interested in the bottom 80 percent than the top 20 percent, so this is broadly good news. The bottom 10 percent do seem to be left behind to some extent, but African poverty has still fallen by 38% during this period, and most health-related metrics have improved. Maybe issuing more unskilled work visas to poor Africans and Indians would help to boost the incomes of the bottom 10 percent even more.

In another post, Krugman points out that the left's "econoheroes" tend to be of a pretty good academic calibre (he cites himself and Joe Stiglitz, both Nobel Prize winners), whereas the most popular economists on the right tend to be slightly less impressive supply-siders. I think that's fair, and it's a pity. When's the last time you heard a right-wing pundit citing Nobel Prize winner (and not-so-secret free marketeer) Eugene Fama's work on the efficiency of financial markets? Or, indeed, Milton Friedman's monetary prescription for stagnant economies like Japan or, now, the Eurozone?

Well, we try to here at the Adam Smith Institute, and a very honourable mention goes to the excellent James Pethokoukis at the American Enterprise Institute. There are others, but in general I think Krugman's point is pretty fair. For example, I often meet right-wingers who think using monetary policy to generate extra inflation during demand-side recessions is somehow a left-wing idea. This would come as a surprise to Milton Friedman!

I have a theory about why: the post-Cold War consensus has been so good for us – that is, the "Overton Window" of debate has shifted so far rightwards — that the best ideas have been absorbed by the 'centre' and the less compelling ones are all that's left over. That seems unsatisfactory to me, but it does leave me wondering what it means to be a free marketeer, if not a strong preoccupation with the supply side. Maybe Hayek has an answer.
