This is a little misleading. Due to ageing, output per person is becoming worse for comparisons of economic performances of countries, esp. for Japan. Better: output per working-age adult. See the recent article by Fernández-Villaverde et al. nber.org/papers/w31914

I think this is an important insight for the labor market literature, one IO economists have been (w/o success) pushing for some time. The key insight from IO is that that concentration is an outcome rather than an input. Some thoughts below... 1/

Recently some prominent people have argued that 19thcentury tariffs were beneficial for American manufacturing. In our new NBER working paper, Alex Klein (Sussex) and I argue: there is no evidence for this assertion. 1/N nber.org/papers/w33100

But I have the (possibly naive) view that people are better off if they're thinking hard about what the truth is and then they can maximize accordingly. They can possibly craft better messages. They can identify real problems. They can evaluate policies better.

Germany had the steepest "vibecession" according to the What Worries the World survey. Not a good situation to be in with elections approaching. ipsos.com/en/what-worrie…

If you look beyond tech giants. US economy isn't that special: - Banking? Worse than EU - Insurance? Worse - Manufacturing? EU growing faster But superstars change everything. 5 tech firms spend 2x more on R&D than entire EU public sector. 3/10

*Trade war: my theory of the case* 1. What is the goal/ideal outcome/trump admin hopes: 10% tariff across the board with no retaliation + direct non-tariff favors from other countries to settle this at 10% + a possible full-scale bilateral trade war with China. (1/n)

Another day, another thread in which Michael Pettis espouses his made-up "beggar-thy-neighbor" theory of trade to justify protectionism. Let's dig in once again to see why this theory is wrong. [1/x]

I don't have more interesting things to do today, so why the hell not... 1) Advocating for protectionism as a response to other countries' market interventions is still protectionism.
