During WWII, Chinese officers who 1) advanced more slowly in their careers, 2) were underpromoted compared to peers, and 3) had ties to people who had better career prospects after their defection to Japan were more likely to defect (X. Fan, G. Richardson, Z. Xu, S. Zhao, April 2026)
nber.orgFrom Mercantilism to Multi-Stellarism: Adapting Historical Economic Models for a Galactic Future.
Hi everyone, I’m a developer and author working on a project called Libernova Space Tycoon which simulates a large-scale galactic economy.
In building this universe, I’ve been fascinated by how historical models—like 17th-century Mercantilism and the 19th-century Gold Standard—could be adapted to a space-faring civilization. For example, if FTL communication is impossible, each star system becomes a 'de-facto' island colony, much like the spice-trade routes of old, but governed by energy-output instead of gold.
I’m currently testing a 'Joules-per-Second' standard for galactic trade. I’d love to hear from this community: Based on historical precedents of colonial trade and hyperinflation, what’s the biggest economic mistake a developing galactic hegemony might make?
Let’s discuss the history of the future.

youtu.beThe Great Divergence and a neglected variable: grain yield volatility as the missing dimension
The Great Divergence debate has generated two decades of productive argument, but I think both sides have been talking past a variable that might resolve the core puzzle. I've written a working paper that makes this case, and I'd welcome pushback from people who know this literature better than I do.
The puzzle that won't go away:
Pomeranz (2000) demonstrated that the Yangtze Delta and England were broadly comparable on many economic indicators as late as the eighteenth century. Allen (2009) argued that England's specific factor prices — high wages relative to cheap energy — created the incentive for mechanization. Huang (1985, 1990) documented "growth without development" in the Yangtze Delta: rising output through labor intensification, yet no transition to the factory system.
Each captures something real. But none answers the underlying question: why did the Yangtze Delta, with fertile soil, an extensive inland waterway network rivaling major European systems, a low disease burden, and the world's largest population, never develop the institutional and organizational preconditions for factory production? Pomeranz points to coal and colonies as England's lucky breaks. Allen points to factor prices. But what determined those factor prices in the first place? And why did the Yangtze Delta's abundant capital — well documented by Li Bozhong and others — never flow into fixed-cost industrial production?
The proposed answer: interannual grain yield volatility.
The continental East Asian monsoon imposed a level of harvest-to-harvest variability on Chinese agriculture that maritime northwestern Europe simply did not face. England's rainfall, moderated by Atlantic westerlies and the North Atlantic Drift, was remarkably stable year to year. The Yangtze Delta's output, driven by monsoon timing and intensity, fluctuated far more severely.
This volatility, I argue, is the variable that explains the institutional divergences both sides of the debate have documented but not fully accounted for:
Land tenure. England's rigid fixed-rent tenancy has long been celebrated as institutionally superior. But fixed rent appeared independently in China — the iron-rent of the Yangtze Delta, perpetual tenancy in certain localities. The legal form was the same. What differed was enforceability. Under recurrent monsoon shocks, rigid fixed rent was effectively unenforceable: harvest failure made tenants insolvent, and landlords had to grant abatements or face violent resistance. Fixed rent collapsed in practice into flexible risk-sharing — de facto sharecropping. In England, extreme harvest failures were rare enough that contracts could be enforced as written. The rigidity was not a superior invention but a dividend of climatic stability.
The Dujiangyan natural experiment sharpens this point. The irrigation system on the Chengdu Plain, built in the third century BC and still operational, virtually eliminated output volatility within its coverage zone. Inside that zone — same culture, same legal tradition, same political system — fixed rent became genuinely rigid, famine abatement clauses were absent or rarely invoked, and a wealthy class of managerial farmers emerged. Outside it, the standard monsoon-driven risk-sharing arrangements persisted. What changed across this boundary was not belief, not culture, not institutions — it was volatility.
Factor prices. Allen's high-wage economy in England was itself downstream of stability. Low volatility supported nuclear family structures and moderated population growth, keeping the labor force relatively scarce. In the Yangtze Delta, high volatility tied labor to the land (leaving meant risking starvation in lean years) and incentivized large families as self-insurance, producing chronic labor surplus that pushed wages to the subsistence floor. The factor-price incentive for mechanization was thus a consequence of volatility conditions, not an independent variable.
Huang's involution. The intensification of household labor that Huang documented was not a cultural preference but a rational adaptation. In a volatile environment, household production carried no rigid overhead and could retreat to self-sufficiency during downturns. The factory system, burdened by fixed costs (wages, rent, equipment, debt service), could not survive the recurrent demand collapses triggered by grain price spikes. Capital rationally avoided industrial investment — not because Chinese merchants were risk-averse or culturally conservative, but because the risk-adjusted returns were genuinely too low. Accumulated wealth flowed instead into land, short-term lending, or hoarding.
The California School's evidence problem. Skinner's influential model of Chinese market structure (1964–65) was built on fieldwork conducted on the Chengdu Plain — within the Dujiangyan stability zone. Pomeranz's and Wong's broader claims of market development comparable to England's drew primarily from the Yangtze Delta, where massive labor input had partially buffered volatility. Neither tradition engaged primarily with the North China Plain, where monsoon volatility was least buffered. When Huang examined the North China Plain directly, he found a qualitatively different economy: commercialization driven by fiscal pressure rather than voluntary specialization, combined with high self-sufficiency and acute household fragility. The scholarship that built the image of a highly commercialized traditional China drew its evidence disproportionately from regions where volatility had been most effectively suppressed.
The testable prediction:
The coefficient of variation of grain yields — calculable from modern climate data fed into low-input agronomic models — should predict land tenure form across pre-modern Eurasia. Regions below a threshold (preliminary indication: CV of roughly 12–20%) should exhibit rigid fixed-rent contracts; regions above it should exhibit sharecropping or flexible rent-abatement; regions near it should exhibit mixed arrangements. The table in the paper maps 21 regions across Eurasia against this prediction, and the correspondence is strong — but systematic empirical testing remains to be done.

Full disclosure: I'm the author. I'd especially welcome challenges from people who work on Chinese agrarian history, European land tenure, or historical climatology. If this variable has already been systematically tested and I've missed the literature, I'd genuinely like to know.

In the early 1900s, computing (performance of calculations) joined teaching and nursing as one of the few careers open to college-educated women in the United States, and it opened doors that few other professions could. (Smithsonian, April 2026)
smithsonianmag.comSince the 1980s, high-achieving professionals in the US – doctors and bankers – displayed growing signs of burnout. This came as a result of businesses seeking more profit per worker just as a more diverse workforce came to these professions in pursuit of upward mobility (Aeon, April 2026)

doi.org"The Economic Logic of China's Rise" — How Geography Endogenizes Distributive Institutions
I'd like to share a working paper that attempts to extend Jeffrey Sachs's geography-and-development framework by identifying a complementary dimension: geographic volatility—the permanent, recurring instability of grain output imposed by climate under pre-modern conditions.
The core argument:
Geography determines not only endowments (soil quality, transport access, disease burden) but also volatility. While endowments shape the *level* of output and hence the extent of the market, volatility shapes the *reliability* of price signals on which the market mechanism depends. This distinction explains what the endowments framework cannot: why high-output regions like the Yangtze Delta nevertheless failed to industrialize spontaneously.
Three contributions:
1. A micro-mechanism linking geography to institutions. Volatility shapes agents' effective time orientation—high volatility forces a high discount rate, making short-term survival the only rational default and blocking full specialization. This provides micro-foundations for "geography precedes institutions."
2. Distributive institutions as endogenous adaptations. Sharecropping vs. fixed-rent tenancy, centralized vs. limited government—these are not independent causes of divergence but rational adaptations to different levels of volatility. The Dujiangyan irrigation case is dispositive: within the same culture and legal tradition, agents inside the engineered stability zone adopted rigid fixed-rent contracts while those outside remained in sharecropping arrangements. What changed was not belief but volatility.
3. A criterion for Big Push success: systemic agricultural de-risking. China's Big Push succeeded because it suppressed grain output volatility to the point where an effective market could take root. The Soviet Big Push failed because it never crossed this threshold. This transforms the Big Push from a general policy prescription into a framework with a clear operational target.
The broader implication:
The low-volatility conditions that enabled spontaneous industrialization are not the norm but a narrow geographic exception—the North Atlantic maritime zone and maritime Japan. For most of humanity, the material foundation had to be built before the market could function. The "engineered invisible hand" is not a deviation from the normal path; for most of the world, it is the only path available.
