It feels weird to me for the World Bank to focus on psychological training to make Togolese people better entrepreneurs but... it does seem to work.

I'm constantly confused by people who see a higher poverty line as a progressive goal, as opposed to shifting focus away from the 40% of the world living on <1/10th of that amount.

$100k (PPP) for a family of 4
= 99.99th percentile in India
= 99th percentile in China
= 93rd percentile in the world

Why aren't there more big, labor-intensive firms in poor countries?

Answer here: bigger firms use more white-color workers who are in shorter supply in poorer countries.

this is a whopper - 600+ pages - but the intro by Besley and Velasco is short easy reading. Is this really the mainstream consensus? A lot of big names are in here, and other big names give positive blubs. If so, it differs from the "mainstream" econ of the popular imagination.

Book launch day -- congrats to @arvind2011.bsky.social & Devesh Kapur!

The book is full of data and historical vignettes, but more importantly, really challenges a lot of received wisdom about India's development trajectory.

Must read.

Every time I talk with @mclem.org about the economics of immigration, I come away a whole lot smarter.

You can enjoy the same experience: He's written a fantastic primer on what the data reveals about the effect of slashing H-1B visas.

It's a banger. Read it.

Botswana credit rating downgraded from BBB+ to BBB, still one notch above the lowest investment grade rating of BBB-.

Botswana started with a A rating in 2001 from S&P, cut to A- after the global financial crisis and to BBB+ during COVID

The external shock hitting Botswana now is very specific

A metaphor perhaps for the international community’s response to Tanzania’s democratic backsliding.

β€œFor all intents and purposes, Nkrumah paralleled Mahatma Gandhi and Martin Luther King Jr. in his reach and influence. That little is known about him outside of Africa and African diasporic communities is a reflection of the continued marginalization of the continent in the Western imagination.”

My experience is if you send Mauricio a half-baked idea, he might just code it up for you and send back a TeX file. Dunno if it’ll work with him as an editor, but worth trying at least…

Lesotho was one of the biggest successes of AGOA -- which meant 'liberation day' hit particularly hard.

Little early to see this in the trade data, but doesn't look great.
