See ‘How Africa Works’ Review: Policies and Prosperity; Four African countries—Botswana, Ethiopia, Mauritius and Rwanda—experienced rapid per capita growth. How did they manage it? William Easterly reviewed the book How Africa Works: Success and Failure on the World's Last Developmental Frontier by Joe Studwell. Excerpts:
"the successful countries were, surprisingly, not very good at following his preferred policies. Botswana’s government promoted neither small-holder agriculture nor manufacturing. Mauritius and Rwanda ended capital controls long ago. Mauritius also successfully promoted manufacturing until it did not, and the share of manufacturing in the economy fell to 11% in 2020 from 20% in the 1980s. The author gives Rwanda a tepid grade on the three policy approaches."
"Ethiopia’s government promoted manufacturing with some successes in cement and floriculture, but its leading state enterprise asked North Korea for help to build 10 sugar mills as part of a vast sugar-development project. (It did not end well.)"
"As for the nonsuccesses, Mr. Studwell notes that some of the three policies were followed there, too. Promoting manufacturing has been a popular idea throughout Africa for decades. Ghana’s enthusiasm for manufacturing contributed to the long decline of its economy, from independence in 1957 to the 1980s. As the author notes, the country encouraged the assembly of automobiles, from kits of car parts, when the value of a finished car was sometimes less than the cost of the parts kit. The author worries that Ghana is repeating this automobile nonsuccess today."
"Nigeria’s Ajaokuta steel plant, which cost billions of dollars but never got around to producing any steel."
"Capital controls were also popular among the nonsuccesses. The author notes how the International Monetary Fund insisted on removing capital controls in the majority of African countries in the 1990s, an indication that the restrictions were widespread at the time. He does not note that these capital controls often went to extremes. When inflation is high, controlled interest rates are far lower than inflation, and capital controls are fierce: Savers can’t preserve their wealth by moving it to dollar-denominated assets outside of the country. Some called such a package financial repression and suggested that savers move their wealth out of banks and into real estate or other real assets (or do not save at all). If savers don’t deposit any money in domestic banks, then the banks will have no money to lend, and borrowers will not get the subsidized bank loans Mr. Studwell favors. Destroying both savings and credit does not seem like a win."
