In light of the genetic evidence about very long-run jati endogamy, what is the best case for the arguments put forth by Bayly and Dirks? I consider Bayly superior, but they both assume, as a matter of course, that caste identities had always been fluid in the pre-modern period without elaboration

Many people are sceptical of Mokyr's idealist take on the Industrial Revolution, but even if you are suspicious, The Enlightened Economy is still a tremendous book. I think this review in JEL gives the correct flavour. It says the comprehensiveness is a curse, but the 'curse' teaches you a lot !!!

I am by nature a hate-poster. When I hate, I post far more extensively, far more volubly, than when I like, let alone when I love (🪢). Last year I disliked. This year I approve highly. So I won't be clogging up your feeds this year as I did last year ;-)

Aghion (et al) have a paper on China, they recognised long ago & before many that the Chinese model departs from the East Asia model in having a Darwinian struggle-to-the-death competition of firms behind a wall of protection. It pairs Schumpeterian growth theory w the economics of industrial policy

The single biggest challenge to previous work on the 'why Europe?' question & which inspired a mountain of new work, came from Pomeranz, The Great Divergence, published by Princeton University Press. One of their bestsellers. That was published in a series of which Mokyr has been editor in chief.

I anticipate some sneers thrown Mokyr's way so my preemptive comment... What ever else he might have done, what ever faults he might have, Mokyr has performed a tremendous service simply by stressing the great importance of the Scientific Revolution to the birth of the modern economy.

Mokyr's work could not have been done today in most economics departments, but the irony is that his work would not fit in history departments today, either. Methodologically he seems more 'history' than 'economics' to economists, but the content and reasoning are too 'economics' for most historians

Four items by Mokyr: the first is a topic already recognised by the Nobel, but the other three are less well known areas of Mokyr: his study of the Irish famine, his explanation of why the Dutch Republic was not the first, and his artisan theory of the Industrial Revolution.

David Wootton, historian of science & author of The Invention of Science, which (in part) argues (contra the HoS orthodoxy) that science played an important part in the history of technology, credits Mokyr for resurrecting that argument. Footnote 11 takes you to 4 major works by Mokyr

I love the Aghion graduate growth theory textbook. There are many reasons, but one small one is that in Acemoglu's (left), developing countries merely import frontier tech & catch up, but in AGH (right) seemingly recognises actual history & suggests indigenous innovation is important à la East Asia

Pseudoerasmus @pseudoerasmus.bsky.social · 13/10/2025

I personally think Robert Allen, another economic historian of the British Industrial Revolution with a theory of innovation as well known as Mokyr's, and are complementary to Mokyr's, should have been included in the Nobel. But I recognise that they don't do fours ;-)

Many misunderstood my meaning so here is a clarification. I was NOT saying the social science lit arguing that war => state formation/capacity is wrong. There is a subtle distinction between that question and the narrower historical question of the little divergence within western Europe.

Wars were mostly bad for European economic development. Might be obvious to ordinary people, but it's not considered obvious in economic history. But I think it's obvious ;-) Below from @sheilaghogilvie.bsky.social

Incredible contribution to our knowledge of global working hours. 1/ Women supply 35% of total hours worked globally 2/ Hours worked do not substantially with income across countries. BUT this stability is produced by reductions in male hours which are offset by rises in female hours

If modest pensions can measurably reduce the practice of old kinship systems (e.g., adult children residing with their parents), perhaps the impact of economic development on cultural change is severely underrated, and the reverse (impact of culture on economic development) highly overrated...

Acemoglu once said (dismissively), "It's all Jack Goody" regarding the (now) popular claim that the Catholic Church created the European Marriage Pattern. When you read Henrich it does seem synthesised from a variety of sources. But in fact their thesis is 95% Goody. He had said it all >40 years ago

Formal manufacturing firms in India have very low exit rates. Yet India’s most dynamic sector, software, has lower exit rates than firms in Morocco or Chile. As far as I can tell, India’s most dynamic states, Gujarat and Tamil Nadu, also have lower exit rates than firms in those countries as well.

Interesting thing about the end of the Atlantic slave trade is, which had the bigger impact, the British suppression of the trade (supply) or the end of demand at the source? Demand is overwhelmingly more important (as the authors also argue). Yet the British naval campaign gets far more attention!

Last year nobody noticed Pickle's lunatic claim that extreme poverty in China rose from 5.6% in 1981 to 68% in 1995! You would think under-5 child mortality would skyrocket under such circumstances. No sign of it (but there was a slowdown in the rate of reduction in the 1980s relative to 1970s).

When Mamdani wins in the NYC mayoral election some of his rich opponents could finance a right-wing remake of his mother's film but this time the Roshan Seth character would be a former grain merchant in Uganda & when he revisits the old country he takes unseemly satisfaction in high maize prices.
