My excellent Conversation with Joe Studwell
Here is the audio, video, and transcript. The conversation is based around Joe’s new and very good book How Africa Works: Success and Failure in the World’s Last Developmental Frontier. Here is part of the episode summary:
Tyler and Joe explore whether population density actually solves development, which African countries are likely to achieve stable growth, whether Africa has a manufacturing future, why state infrastructure projects decay while farmer-led irrigation thrives, what progress looks like in education and public health, whether charter cities or special economic zones can work, and how permanent Africa’s colonial borders really are. After testing Joe’s optimism about Africa, Tyler shifts back to Asia: what Japan and South Korea will do about depopulation, why industrial policy worked in East Asia but failed in India and Brazil, what went wrong in Thailand, and what Joe will tackle next.
Excerpt:
COWEN: Does Africa have a manufacturing future? Is robotics coming, AI, possibly some reshoring?
STUDWELL: Yes. I believe that Africa does have a manufacturing future.
COWEN: But making what? And at what cost of energy?
STUDWELL: They will start, as everybody does, producing garments, producing textiles, which in certain enclaves is already going on in Madagascar, in Lasutu, in Morocco, and they’ll move on to other things. They’ll start with those things because they are the most labor cost-sensitive products.
Africa is now in a position where — depending on which state you’re looking at, and taking China as a reference point — the cost of labor is now between a half and one-tenth of what it is in China. Factory labor is now around $600 a month at its cheapest. In a country like Ethiopia or Madagascar, it’s $60 or $65 a month. So, it’s a 10th of the cost, and that’s already beginning to have a bit of effect, often with Chinese firms moving production to Africa.
So, I think there is a future for manufacturing. It will depend on the extent to which African governments understand that you don’t really move forward fast for very long without manufacturing, that every developed country — apart from a few petro states and financial centers — has gone through a manufacturing phase of development. It depends on the extent to which African governments engage with that, but some, without doubt, will.
The Ethiopians, for instance, have already attempted to do that. What they’re trying to do has been somewhat derailed by the two-year civil war that took place from 2020, but they’re back on it now, and they’re trying to move forward.
The idea that robotics and AI are going to change the story I personally do not buy, principally for two reasons. One is the cost reason, because whenever people talk about what’s happening with robotics, no one ever talks about the cost of robots. In garmenting, for instance, even a basic robot will cost you in excess of $100,000, and you pay the cost upfront, and you’ve then paid that, whether there’s demand for your products or not. Also, in garmenting and in textiles, robots don’t work very well because they can’t work with material very well. They’re much better at working with solid things.
So, you’ve spent $100,000 for a robot when you can go out in somewhere like Tana in Madagascar and get another skilled — because they’ve been doing it now for 20 years — garmenting employee for $60 or $65 to make the new order that you just got. And if the order doesn’t come through, you can sack them. You see what I’m saying? There’s a point about the cost of robotics.
COWEN: But think of automation more generally — it’s not that expensive. Most countries are de-industrializing. Even South Africa has been de-industrializing for a while, and China maybe has peaked out at industrialization, measured in terms of employment. It’s hard to trust their numbers. But maybe just everywhere is going to deindustrialize, and that will be very bad for Africa.
STUDWELL: I don’t think so. I think South Africa is deindustrializing because the ANC has followed a hyper-liberal approach to economic policy. I don’t think the ANC has ever really understood economic policy, frankly, so South Africa is an outlier in that respect. There are many other states in Africa, whether Nigeria or Ethiopia, which understand they’ve got to have a manufacturing future and intend to pursue one.
Then, as I was saying, the other point is, what people miss is the flexibility with robotics and AI. There’s very limited flexibility with robotic and automated production. When demand goes up, you can’t just stick in more robots, but when demand goes up in a people-operated factory, where the cost of labor is low, you can stick in more people and produce more.
Just one example: during COVID, when everybody was having home deliveries of supermarket goods, the price of a UK firm called Ocado, which runs a supermarket, but was also developing the software and consulting around building blind warehouses went up through the roof, but now it’s down through the floor.
And only last week, Kroger supermarket in the US said, “We’re closing five of these super-modern blind warehouses.” And the reason, fundamentally, is because they lack the flexibility that human labor brings to the job. So, I’m not saying that robots, automation, and AI are not important. They are important. What I am saying is that they are not going to derail a manufacturing future for a number of African countries that aggressively pursue it.
COWEN: But there’re a lot of developing nations around the world — you could look at India, you could look at Pakistan, even Thailand — where manufacturing has not taken off the way one might have wanted. There’re just major forces operating against it. And in the US, manufacturing employment was once 37 percent of the workforce; now it’s 7 percent to 8 percent.
It just seems like it’s swimming upstream for Africa — which again, has quite expensive energy — to think it will do that well. And again, South Africa had very good technology, pretty high state capacity. I don’t see the alternate world state where a wiser ANC would have made that work.
STUDWELL: Well, oddly enough, before the end of Apartheid, the manufacturing performance of South Africa was really not bad at all, with classic industrial policy, quite high levels of protection, and so forth. I think that demand for manufactured goods will continue to be high around the world, and the labor cost will continue to be a prime determinant of where producers go for low value-added goods. So, I think that the opportunity is there for African countries.
COWEN: But say there’re transportation costs internally, energy costs, political order uncertainty. Where’s the place where people really want to put all these manufacturing firms?
Interesting throughout, recommended.
Germany projection of the day
Germany’s population is projected to shrink by nearly 5 per cent within 25 years — a significantly steeper decline than previously forecast, according to an Ifo study.
The German economic think-tank on Tuesday revised its forecast for a 1 per cent population decline by 2050 to nearly 5 per cent — a drop that would leave Germany with its smallest population since 1990. The revision is based on updated figures from the country’s statistical office.
“Demographic change will have significant effects on all areas of the economy and society,” Ifo economist Joachim Ragnitz warned in the study.

Science should be machine-readable
One of the leading tasks of our time:
We develop a machine-automated approach for extracting results from papers, which we assess via a comprehensive review of the entire eLife corpus. Our method facilitates a direct comparison of machine and peer review, and sheds light on key challenges that must be overcome in order to facilitate AI-assisted science. In particular, the results point the way towards a machine-readable framework for disseminating scientific information. We therefore argue that publication systems should optimize separately for the dissemination of data and results versus the conveying of novel ideas, and the former should be machine-readable.

Rebuilding our world, with reference to strong AI
When 2012 passed into 2013, we did not have to rebuild our world, not in most countries at least. It sufficed to make adjustments at the margin.
After the Roman Empire fell, parts of Europe had to rebuild their worlds. It took a long time, but they ended up doing pretty well.
After the American Revolution, the newly independent colonies had to rebuild their own world. They did so brutally, but with considerable success.
After WWII, Western Europe had the chance to rebuild its own world, and did a great job.
We moderns are not used to having to rebuild our world.
It is now the case that strong AI is here/coming, and we will have to rebuild our own world. Many of us are terrified at this prospect, others are just extremely pessimistic. It seems so impossible. How are all the new pieces supposed to fit together? Who amongst us can explain that process in a reassuring way?
Yet we have done it many times before. Not always with success, however. After WWI ended, Europe was supposed to rebuild its own world, but they came up with something far worse than what they had before. Nonetheless, in the broader sweep of history world rebuilding projects have had positive expected value.
And so we will rebuilding our world yet again. Or maybe you think we are simply incapable of that.
As this happens, it can be useful to distinguish “criticisms of AI” from “people who cannot imagine that world rebuilding will go well.” A lot of what parades as the former is actually the latter.
In any case, it all will be quite something to witness.
“You see tech and AI everywhere but in the productivity statistics”
How many times have I heard versions of that claim? Erik Brynjolfsson picks up the telephone in the FT:
While initial reports suggested a year of steady labour expansion in the US, the new figures reveal that total payroll growth was revised downward by approximately 403,000 jobs. Crucially, this downward revision occurred while real GDP remained robust, including a 3.7 per cent growth rate in the fourth quarter. This decoupling — maintaining high output with significantly lower labour input — is the hallmark of productivity growth.
My own updated analysis suggests a US productivity increase of roughly 2.7 per cent for 2025. This is a near doubling from the sluggish 1.4 per cent annual average that characterised the past decade.
It is fine to suggest caution in interpreting such statistics, but they hardly push the other way.

Malthus had real influence
From a recent paper by Eric Robertson:
Public officials often fail to implement government policy as directed, yet the role of economic ideas in shaping these implementation choices is poorly understood. This paper provides causal evidence that exposure to economic ideas can durably influence bureaucrat behavior. I study British colonial bureaucrats in India, exploiting a natural experiment created by the abrupt death of Thomas Malthus in 1834, replacing his economics instruction at a bureaucrat training college for that of a contemporary critic, Richard Jones. Whereas Malthus regarded economic distress as a natural mechanism for restoring equilibrium by reducing population growth, Jones disagreed with this view. Linking rainfall shocks to district-level fiscal responses, I show that officials trained by Malthus delivered less relief during droughts, providing 0.10-0.25 SD less aid across all major measures compared with officials taught by Jones. The results reveal that exposure to abstract economic ideas can shape real-world policy implementation for decades.
This may be a case where using rainfall shocks in a paper actually makes sense. Via Krzysztof Tyszka-Drozdowski.
At the Grand Egyptian Museum
Neal Spencer has a good review at the LRB, excerpt:
Over the past few decades, however, Egyptian museums have pivoted away from Europe and America. The National Museum of Egyptian Civilisation, which opened in 2021, rejected the traditional division of artefacts into pharaonic, Coptic, Greco-Roman and Islamic eras (a framework associated with European academic disciplines). The Grand Egyptian Museum, announced at the height of Hosni Mubarak’s rule and styled ‘the largest museum in the world dedicated to the people, history and culture of Ancient Egypt’, opened in November last year with a lavish ceremony broadcast round the world. It is estimated to have cost more than $1 billion ($300 million of which was a loan from Japan) and sprawls over an area the size of seventy football pitches. The financial crash of 2008, the Arab Spring and Covid meant that its construction took almost twenty years. Much has changed in that time. The last decade of construction took place under the military regime of Abdel Fattah el-Sisi, who installed one of his generals as its head – the first non-Egyptologist to direct a major Egyptian museum.
I saw the museum shortly after the opening and found it pretty spectacular, both the building/setting and the collection. It is worth making a trip to Cairo just to see this, and it now can be considered one of the world’s great museums and history sites (yes I had seen the earlier incarnation of the museum, years ago). The very wise Rasheed Griffith also gave the museum an A+.

The cocaine problem seems to be getting worse again
Colombian coca cultivation fell dramatically between 2000 and 2015, a period that saw intense U.S.-backed eradication and interdiction efforts. That progress reversed in 2015, when peace talks and legal rulings in Colombia opened enforcement gaps. Coca plantation has since increased to record levels, which coincided with a sharp rise in cocaine-related overdose deaths in the U.S. We estimate how much of that rise can be causally attributed to Colombia’s new coca boom. Leveraging the unforeseen coca supply shock and cross-county differences in pre-shock cocaine exposure, we find that the surge in supply caused an immediate rise in overdose mortality in the U.S. Our analysis estimates on the order of 1,000–1,500 additional U.S. deaths per year in the late 2010s can be attributed to Colombia’s cocaine boom. Implicit annual loss in American statistical life values about $48,000 per hectare of cultivation in Colombia. If left untamed, the current level of coca cultivation (over 230,000 ha in 2022) may impose on the order of $10 billion per year in costs via overdose fatalities.

Changes in the Gender Wage Gap for Business Professionals
In the United States, much of the gap in earnings between men and women is due to the persistent gap for high wage earners. This paper explores changes in the gender wage gap for MBAs graduating from a large public university over 30 years. We document large gender wage gaps on average, which grow in the course of men’s and women’s careers. Comparing graduates at identical career stages across time periods to address composition concerns, we show that the raw gender wage gap has shrunk by 33 to 50 percent over the last two decades. Additionally, the temporal pattern of the gap has fundamentally shifted: while gaps only emerged over time in earlier decades, significant gaps now emerge immediately. Convergence in labor supply factors, particularly hours worked, explains much of the narrowing gap, alongside shifts in industry composition. However, unexplained wage gaps persist for recent graduates from the very start of their careers, suggesting different underlying mechanisms across cohorts. These findings highlight both progress in gender wage equity among business professionals and concerning patterns that emerge earlier in careers than in previous decades.
