So this is public now, so: I’m officially starting a Works in Progress-style magazine focusing on the developing world! It is called In Development, and first call for pitches will be coming at the end of the year.

Jeune Afrique a infiltré une chaîne Telegram privée du groupe Wagner. Il en ressort un quotidien de torture, d’exécutions et de profanations de cadavres, en particulier au Mali. Des crimes de guerre racistes, documentés par leurs auteurs pour un public à tendance néonazie.

Tremendo paper.

And it's a wrap. The last chapter of my dissertation is out today. It's hard to explain to those outside the profession how much work goes into a paper — and how personal they become. I hope you enjoy reading it. [continues]

We do this through the NHANES, among the most valuable surveys we have to monitor metabolic health, diet, weight, etc, etc. Core people needed to run this survey were fired and now...maybe it will not exist. How, exactly, is this helping us make America healthy again?

Do incumbents buy startups to scale innovation or to stifle it? New research covering 60 countries finds that acquired startups were highly innovative before their acquisition, but their patenting drops sharply afterward, while acquirers' innovation doesn't rise.

Mokyr never published in a «top 5» journal until very late in his career, when he finally did together with David de la Croix & @mdoepke. Later he did so again, w/ Morgan Kelly and Cormac Ó Gráda. Whatever you think of the Nobel Memorial Prize in Economic Sciences, consider that.
