The Long Divergence

by Timur Kuran

(The final calendar entry for the 29 July reading:)

On 29th June, we wrapped up discussing “The long divergence” by Timur Kuran. The book’s strength lies in what it promises: why did the middle eastern countries develop slowly compared to their western counterparts, despite being richer in the 13th century. The book presents a lot of research to answer this, but really struggles with finding a plausible answer. It also struggles with finding it’s identity. Is it a historical narrative? Is it an economic narrative, seeking to establish a causal story? Perhaps an interested reader should just read the last part (Conclusion). It has a summary of the features of Islamic law+the cultural preferences of the people of the Middle East that were in place at the start of the 13th century, and a summary of the three (BIG) features that Kuran is persuaded created the long divergence. But since all this was true for other regions, which didn’t end up in the same place as the Islamic countries, the puzzle is left unresolved. The book has a hopeful end about the Middle East though: that many of the features of the Middle Eastern countries/society that has been attributed to the growth gap are being replaced and adopted integrally with modern institutions. So in the future, these societies will be as vibrant as anywhere in the world. And the long divergence will be a small blip in the sands of history.

Both Pillai’s “Guns, Gods and Missionaries” and Kuran’s “Long Divergence” have been heavy, brain wracking efforts. For the next reading, we plan to read fiction. Science fiction. Two books (because I couldn’t choose, and couldn’t find a coin to flip).

  1. “Flowers for Algernon”, by Daniel Keyes

  2. “A fall of moondust”, by Arthur C. Clarke

Read one or read both. But come and let’s figure what science fiction is all about before we revert to our regular schedule!

When: 5:15-7:15pm, 29th July (Wednesday)

(What was the first entry on the Long divergence:)

We are reading “The long divergence” by Timur Kuran. The puzzle that the book explores is why did the middle eastern countries grow so much more slowly than their western (European) counterparts. They both started at the same level in the 5th and the 6th centuries, but by the 17th/18th century, European societies were far more wealthy and more developed. Why did the industrial revolution happen in Europe rather than in the Middle East (ME). Kuran’s thesis starts from identifying Islam as the force that brought together, and kept together, the nomadic tribes of the ME, and that the source of the long divergence is the religion/the religious texts. So far as Parts I and II goes, he identifies the institutional features of Islamic partnership organisations - the waqf - as a key culprit, although these were how orgs started in Europe as well. So the ME got equal rights for all, including women, in inheritance but no long lived firms, that could readily pool diversified capital. They were in an equilibrium that they couldn’t break out of, unlike the societies in Europe. Banks appeared in European organically, and had to be imported into the ME with courts that worked along the lines of the European courts of dispute resolution. Was it because contract enforcement can not be visibly implemented in a society with “equal rights”? Was the lack of credit markets with differential interest rates a result of this, and in turn, the cause of the lack of long tenor credit contracts? By the end of Part II, Kuran seems to have fleshed out the puzzle of the Long Divergence in great detail but not really identified a credible reason. Which makes me curious about the second half. Let’s meet and discuss how he concludes on the 29th.

(The first long entry for the 29th July reading, which summarised The long divergence below.)

On 29th June, we wrapped up discussing “The long divergence” by Timur Kuran. The book’s strength lies in what it promises: why did the middle eastern countries develop slowly compared to their western counterparts, despite being richer in the 13th century. They were as smart, as interested in being rich, wanted to be more egalitarian (for example, their inheritance laws that gave equal parts of the property to all immediate family members, regardless of gender). What they were not was open to explicit dissociation with the Islamic law. When the law said corporations cannot expand from their original contributions/contributors, or that different ethnic/religious groups should have their own laws and enforcement mechanisms, this stuck as part of their culture. Kuran presents this as an absolute barrier to growth in the region. But he presents many things as equally absolute barriers to this growth. This rapidly confuses the reader because surely not everything can be an absolute barrier to growth. There is a lot of research and documentation in the book that is pitched as critical as an answer to the puzzle, but it is left to the reader to craft her own answer with little guidance of what is more important, or less. What makes this especially difficult is the repeating appearance of the same argument at different places with different references, different contexts. The book really struggles with finding it’s identity. Is it a historical narrative? Is it an economic narrative, seeking to establish a causal story? The book reads as if each of the two identities fought, won and made an appearance at different places in the book.

Perhaps an interested, sympathetic reader, should just read the last part (Conclusion). It has a summary of the features of Islamic law+the cultural preferences of the people of the Middle East that were in place at the start of the 13th century, and a summary of the three (BIG) features that Kuran is persuaded created the long divergence. But even he admits that the same was true for other regions, which didn’t end up in the same place as the Islamic countries. The puzzle is left unresolved. The book has a hopeful end about the Middle East though: that many of the features of the Middle Eastern countries/society that has been attributed to the growth gap are being replaced and adopted integrally with modern institutions. And that in the future, these societies will be as vibrant as anywhere in the world. And the long divergence will be a small blip in the sands of history.

(Notes while reading the book:

8 Curious: for all that inheritance laws gave women equal access to the family wealth, why was there no difference in gender equality in the ME compared with the West? In fact, why did it emerge as worse?? For instance, could a woman start / manage a waqf? Kuran doesn’t seem interested in such questions.)
