World-System (0-2000) What Caused the Industrial Revolution?
The graphic above is a time plot of World Aggregate Production (W_Q) taken from Maddison (see the Boiler Pate). The growth of Capitalism is typically data from 1500-Present with a clear visible take-off starting in the 19th Century. The burning question is "Why"!
ChatGPT (an AI Systems) produces the graphic above as an answer to the question "What Caused the Industrial Revolution".*** One can quibble with some of the links in the graph ("Why aren't Profits plowed back into the production process?", "What about Environmental Impacts?", etc.), but the graph is a good place to start.
Notes
- a combination of the Agricultural Revolution, which freed up labor and increased foodproduction;
- technological innovations like the steam engine and new machinery that mechanized production;
- access to natural resources such as coal and iron;
- economic and political factors like capitalism, available capital, and supportive government policies;
- and an increase in population growth and made, which created both a work force and demand for goods.
Agricultural advancements
Technological innovation
New inventions:
Key inventions like the spinning jenny, water frame, and steam engine revolutionized production in the textile and other industries.

World-System (1960-2500) Unstable System Cycles in Latin America
In an earlier post (here and here), I found that the best forecasting model for Argentina was the LA20 Model (Latin America Regional Economy). Out until 2100 (the furthest out the IPCC is willing to go on Global Emission Scenarios), it looks as if Latin American Integration would provide a desirable future, at least for Argentina (here). This post explores what happens after 2100, out to 2500. Of course, no one knows the future (especially out to 2500), but the LA20 Model is a computer program that can be run out to any date. Sometimes it is insightful just to see what happens!
The LA20 Model is unstable and cyclical (the eigenvalues and AIC statistics are presented in the graphic above for the Business as Usual BAU model). In the Phase Plot, above, time moves from left to right and cycles increase in magnitude and severity.** Although the short-term future might look endurable, the long-term future is not. Luckily, a lot (maybe everything) can change after 2100, especially in the face of Environmental Crisis.
Another reason to look at long-run cycles in Latin America is that cycles (particularly Kondratiev Waves or K-Waves) are discussed extensively and qualitatively in World-Systems Theory. It is refreshingly concrete to see actual historical cycles tested with a statistically estimated model. However, a future of unstable cycles is probably one reason why Latin American Integration has been so problematic.
Notes
** And will require that bailouts increase in magnitude and severity.
LA20 BAU Measurement Matrix:
You can experiment with the LA20 BAU model here. Suggestions are given in the code for how to stabilize the model.
Ex. 1.0 Can you find a way to eliminate cycles once the model has been stabilized?
The solution to this Exercise can be found in the LA_TECHP model which I will describe in a future post.
Descriptions of the how the Dynamic Component State Space models are constructed are given in the Boiler Plate.

World-System (1950-2100) How to Balance the World System
In an earlier post (here), I found that the US-MX-CA World Trading System could reach a Steady State in a number of ways.
Creating a Steady State in the World System, keeping Industrialization and Environmental Degradation in balance, involves mitigating the cascading effects of Collapsing Oil Markets and collapsing Agricultural markets.
- Oil and food production (through the oil-driven Green Revolution) are essential for Industrial society. We typically don't think of oil markets and agricultural markets as historical feedback controllers, but they will become controllers when Peak Oil is reached (oil is a non-renewable resources). Electric vehicles, wind and solar energy serve to reduce feedback effects from Oil Markets.
- Current uses of oil (burning in combustion engines, making plastic bottles, medical devices, industrial fertilizers, etc.) will be restricted after Peak Oil. It would be prudent to reduce industrial growth rates and conserve existing supplies of all scare, non-renewable resources.
Notes

- WL20 In the graphic above, the dark black line is the basic model forecast: slowing growth in the present and collapse shortly after that.
- F[1,2] = 0 The coefficient -0.02519461 is the negative feedback effect of food production, W2. Without this feedback effect, collapse happens more rapidly.
- F[2,3] = 0 The coefficient -0.05250691 is the negative effect of the Oil-Market-Footprint W3, on food production, W2. Eliminating this feedback effect reduces the amount of collapse after 2050.
- F[2,3] = F[3,2] = 0 Eliminating the interaction between W2 and W3, leads to gradual growth and then a steady state after 2100.
- F[1,1] = 1 Finally, setting growth to a Random Walk, results in an immediate steady state.
