Tyler Cowen interviews Joe Studwell, a distinguished journalist and author best known for How Asia Works, which gained major recognition for analyzing successful Asian development strategies. Studwell has just released How Africa Works Success and Failure on the World's Last Developmental Frontier, examining development challenges across Africa through the lens of population density, agricultural transformation, and private sector growth.

The conversation explores Africa's development prospects, with Studwell arguing that low population density—not governance failures—has been the continent's primary obstacle. They discuss specific countries like Nigeria, Botswana, and Tanzania, examining why some succeed while others struggle despite natural resources or good governance.

The discussion expands to broader development questions, covering manufacturing futures, human capital development, disease burden reduction, and the effectiveness of industrial policy. Studwell draws comparisons between African and Asian development paths, while addressing concerns about automation, energy costs, and political stability across the continent.

Population Density as Africa's Core Development Challenge

How Africa Works argues that very low population density, not governance issues, has been Africa's biggest development problem since independence.

"In 1960, Africa had population density which was one-fifth that of Asia as a whole and one-seventh what it was in East Asia" - Joe, attributing this to the continent's unique disease burden.

Nigeria's underperformance despite higher density stems from "terrible civil war" and "ethnic divisions that are particularly acute even by African standards" with three roughly equal groups fighting for power.

Botswana succeeds as an outlier because "the economy is a giant diamond mine" requiring only 10,000 workers, making population density irrelevant for mineral-based development.

Africa's Agricultural Revolution and Private Sector Growth

"We've had the fastest average rate of agricultural GDP growth since 2000, about 4.5% in Africa compared with anywhere else in the world" - Joe, marking a dramatic shift from previous decades.

Farmer-led irrigation has added 3-4 million hectares of irrigated land through individual farmers buying pumps and digging boreholes, replacing failed state-led projects.

Large agribusiness firms like Tanzania's Bachraza now operate across 8-10 countries in east and southern Africa, owning football clubs, TV stations, and petroleum businesses as diversified conglomerates.

African farmers near cities are "getting up towards Asian yields" due to this farmer-led irrigation and improved agricultural practices.

Manufacturing Potential Despite Automation Concerns

Factory labor costs in Ethiopia and Madagascar are "$60 or $65 a month" compared to China's $600, creating a ten-fold cost advantage for labor-intensive manufacturing.

"Even a basic robot will cost you in excess of $100,000 and you pay the cost upfront" - Joe, arguing robots lack flexibility compared to hiring workers for $60 monthly when demand increases.

Ethiopia has achieved electricity costs "at a fraction of other African countries" through aggressive industrial policy combining hydro, wind, solar, and geothermal power.

Chinese Belt and Road Initiative invested $150 billion in Africa since 2013, with "80% going to roads and power and water and other utility stuff" rather than just mining infrastructure.

Education Progress and Human Capital Development

Africa achieved "the fastest developed formal education system that the world has ever seen" according to World Bank reports, raising literacy from 16% in 1960.

"In some measures, education performance in Africa now exceeds South Asia, which is pretty remarkable given that South Asia was very far ahead in 1960" - Joe.

Tanzania's Nyerere government "increased literacy from just over 10% to 80% in one generation" through massive resource mobilization for education.

Countries like Rwanda and Ethiopia have made "significant investment in vocational education" while Ghana and Nigeria continue producing high proportions of Africa's university graduates.

Industrial Policy Effectiveness and Asian Development Lessons

Industrial policy "has worked extremely well" through "targeting cheap money at manufacturing, putting some protection in place, rewarding exporters of manufactured goods" - Joe.

How Asia Works demonstrates that developmental states achieved "stable growth rates of five, six, seven, eight percent" which "signaled very effectively to the private sector" and encouraged investment.

Industrial policy failed in India because "people like Mahalanobis were just absolutely clueless" and "didn't understand that competition is fundamental to effective industrial policy."

The challenge is "getting away from industrial policy" and "the trade surpluses that it tends to produce" as seen in Japan, Germany, and China becoming "a problem for the whole of the rest of the world."

East Asian Demographic Crisis and Future Challenges

South Korea's birth rate crisis creates an impossible choice: "They don't want those Africans coming in to do the jobs" and subsidies have "a very poor record" globally.

"Depopulation is way more serious than population growth ever was" - Joe, noting the irony after 250 years of Malthusian fears about overpopulation.

Japan's debt-to-GDP ratio of "something between 200 to 230%" may require inflation to solve, similar to how "Britain got out of the same level of debt after the Napoleonic Wars."

China is "much more cosmopolitan" than Korea or Japan, making demographic challenges "more difficult for Korea and Japan because the populations don't want foreigners coming in."
