Ronald Regan said economists can give 3,000 answers to 100 questions.
The social sciences are so tricky because people are so gosh darn peculiar. That’s why I’m so drawn to when economics nears a consensus. That work can improve public policy, and helpfully the work has lessons for those across the political spectrum.
One long-central wellspring of debates: The role of government. As Australian economist Andrew Leigh writes in his short, snappy 2024 book How Economics Explains the World: “Capitalism doesn’t guarantee the well-being of those who lack capital.”
Elsewhere though, his breezy look through the discipline reminds there are times to avoid intervention. Below I share my notes for future reference.
My notes:
- “Economics can be defined as a social science that studies how people maximize their well-being in the face of scarcity”
- Thomas Carlyle called economics “the dismal science” because he wanted slavery back
- Elinor Ostrom: Nobel research on cooperative environments
- Thomas Thwaite’s project to build a toaster from scratch
- Author: “Hobbes was right. Rousseau was wrong.” (Look at Dawn of Everything)
- In ancient Kalibangan (in India), they hit right brick proportions at 1:2:4
- But Indus River valley didn’t have “a monumental problem” because it was relatively equal — pantheon, pyramids, acropolis were built in more unequal societies
- “Consumption smoothing” : farming allowed a food surplus , so consumption is less volatile than income (production)
- Fertile crescent’s 8 founder crops
- Gender dynamics are more equal in places where (stronger male dominant) plough use was less common (Rwanda, Madagascar), than more common (Mauritania , Ethiopia)
- Eurasia had more plant/animal species domestication, and was wide, which allowed more similar harvest patterns: Jared Diamond influentially argued this is why colonizers were European
- Farming technology allowed Indus Valley to become more equal but it also allowed autocrats (look at Harari in his Nexus book noting that technology isn’t deterministic but it creates chances to reset)
- Agricultural Revolution was initially bad for health (heights declined), but innovation rebounded
- Why didn’t Egypt create the wheel? Labor costs were low. Likewise ancient China didn’t export its innovations for economic gains
- Money is a unit of account, a store of value and a medium of exchange

- Spain’s earlier colonial success was a resource curse, collapsing its domestic industries and driving inflation
- Why did Europeans build in Canada, United States, Chile and Australia, but extract in Nigeria, Congo and Angola? The mortality rate of them were lower in the former (malaria) — the Mayflower was considering Guyana as an alternative
- Dutch East India company vs British East India
- As a rule of thumb, economists teach that you should only insure items that cost more than a month’s income.
- Between 1820-1900, living standards in Europe more than doubled, but Asia and Africa did not rise at all

- The Tolpuddle Martyrs were a group of six English farm labourers who, in 1834, were arrested, tried, and sentenced to transportation to Australia for forming a trade union. Their case became a rallying point for the nascent trade union movement and is now seen as a key moment in the fight for workers’ rights.
- Alfred Marshall: Marshallian cross of supply and demand; fixed and variable costs
- Marshall famous for popularizing economics with examples: “burn the mathematics”
- David Galenson on creatives: “conceptualists” bring a breakthrough idea at a young age (Van Gogh, Picasso; ee Cummings, Sylvia Path; James Joyce and Herman Melville; Orson Welles); “experimentalists” master a process (Rembrandt; Michelangelo, Cezanne; Wallace Stevens; Charles Dickens; Virginia Woolf; Clint Eastwood) https://www.wired.com/2006/07/genius/
- Migrants are a source of both demand and supply
- Elinor Ostrom: tragedy of the commons research shows not that management of resources is inevitable but possible
- Irving Fisher’s legendary claim of a “permanently high plateau,” days before Stock Market Crash
- Keynes: depression was like a bee colony in which all the bees decided to live thrifty — spending related, and so government investment made sense
- Hayek more saw recessions as necessary forest fires to clear out underperformed (Keynes saw them as natural disaster that could strike)
- Hayek: invisible hand; Keynes: animal spirits
- Smoot Hawley Acts and depression austerity: migration from Europe was lower in 1830s than the Mid 1800s
