There is no long run. This short note from the Fed suggests that the failure of output to return to its earlier trend following the Great Recession is not an anomaly; historically, recessions normally involve permanent output losses. This working paper by Lawrence Summers and Lant Pritchett argues that it is very hard to find persistent growth differences between countries. From opposite directions, these results suggest that there is no reason to think that supposedly “slow” variables are more stable than “fast” ones; in other words, there is no economically meaningful long run.
Krugman on the archaeology of “price stability.” Here is Paul Krugman’s talk from the same Roosevelt Institute/AFR/EPI even I spoke at last month. The whole thing is quite good but the most interesting part to me was on the (quite recent) origins of the idea that price stability means 2 percent inflation. From Adam Smith until the 1990s, price stability meant just that, zero inflation; but in the postwar decades it was more or less accepted that that was one objective to trade off against others, rather than the sine qua non of policy success.
Capital is back — or is it? Here’s an interesting figure from Piketty and Zucman’s 2013 paper, showing the long-term evolution of capital and labor shares in the UK and France:
What we see is not a stable or rising capital share, but rather a secular shift in favor of labor income, presumably reflecting the long term growth of political power of working people from the early 19th century, when unions were illegal, labor legislation was unknown and only property owners could vote. What’s funny is that this long-term decline in the power of capital is so clearly visible in Piketty’s data, but so invisible in the discussion of his book.
Orange is the big lie. Like lots of people, I watched the Netflix show Orange Is the New Black and initially enjoyed it, enough to read the memoir on which it’s based. It’s not often you see ideology operation so visibly: The show systematically omits the book’s depictions of abuse and racism among the guards and solidarity among the prisoners, and introduces violence from the prisoners and compassion from the authorities that is not present in the book. For example, both book and show feature an affair between a female prisoner and a male guard, but in the show nothing happens to the prisoner while the guard is fired and prosecuted, while in reality the prisoner was thrown into solitary confinement and there were no consequences for the guard.
