World-System (1970-2100) Latin American Futures
- BAU The Business as Usual model (which you can run here) is cyclical but has the best growth out to 2100.
- TECHE The Technical Efficiency model is stable and a strong contender (AIC = -160.3, smaller is better).
- TECHP The Technical Productivity Model is also stable and has one of the best statistics (AIC = -264.3). This model is the Systems Theory analog of the Neoclassical Economic Growth Model with erogenous technological change.
- US The model drive by the US is also stable, cyclical and an obvious contender given the history of Latin America (AIC = -85.96).
- RW In the short run, the Random Walk is a strong contender (AIC = -108.1)
- W The World System input model is stable, cyclical and also a strong contender (AIC = -71.53). Unfortunately, it leads to collapse starting in the very near future.

World-System (1980-2100) Six Forecasts for the United Kingdom
The US and the United Kingdom (UK) recently signed a Technological Prosperity Deal (I posted about the Deal here). After Brexit (the withdrawal of the UK from the European Union, EU), it seems that the purpose of the deal is obvious: the UK needs friends and Geopolitical Alliances after having essentially snubbed the EU. The US is the obvious next choice. But, the question remains: what would be the best Geopolitical Alliance for the UK? This post explores that question using the UKL20 Model (for more information about how the model was created, see the Boiler Plate).
The best Geopolitical Alliance for the UK is none, that is, to remain independent in the World-System and conduct Business as Usual (BAU) muddling through as necessary (RW).
In the graphic above are six growth forecasts for the UK1 state space component. From the Political Perspective, the UK-BAU Business As Usual models are the best, better than staying linked to the EU (a rationale for Brexit). The BAU models are unstable (largest eigenvalue greater than 1.0). The weaker models (EU, US, and W) are all stable and lead eventually to a Steady State Economy (a better result for reducing Environmental Degradation). The best short-term, year-to-year model is the Random Walk (RW), just muddling through.
You can experiment with the UKL20 Model and investigate the Technology models (TECHE and TECHP) here.
Notes
- RW Random Walk [11.69 < AIC = 20.71 < 30.63]
- BAU Business As Usual [81.86 < AIC = 87.22 < 91.8 ]
- W World WL20 Input [34.58 < AIC = 60.83 < 82.67]
- US USL20 Input [29 < AIC = 63.25 < 90.17]
- UK UK2_UK3 BAU Input [83.88 < AIC = 89.88 < 94.15]
- EU European Union [60.47 < AIC = 79.99 < 97.75]
- TECHP Technical Productivity [27.43 < AIC = 48.29 < 66.77]
- TECHE Technical Efficiency [61.16 < AIC = 73.08 < 82.33 ]

World-System (1960-2100) Technological Change in the United Kingdom
On September 18, 2025 Donald Trump and Keir Starmer signed a Technological Prosperity Deal between the US and the UK covering joint technological advancement. Aside from giving the US President a chance to ride in the Golden State Carriage with King Charles, what was the motivation for the visit and the Technological Prosperity Deal?
The Economy of the UK is driven by Technological Productivity (TECHP) change; without accelerated Technological Productivity growth, the UK is facing a Steady State Economy or even Limits to Growth.
In this post, I present results from the UKL20_TECHP model to explain the forecast. The TECHP Indicators and index construction are explained in the Notes.
The Technological Prosperity Deal is an attempt to put off the steady state and approach the 98% upper confidence interval where TECHP reaches a much higher level, but still a steady state.

World-System (1960-2100) A New "Axis of Evil"?
On September 1, 2025, in the Chinese port city of Tianjin, Chinese President Xi Jinping held a summit in response to the Trump II Administration tariff policies that included leaders of Russia and India and other representatives from the Global South (here). Xi declared that "Global governance has reached a new crossroads," in the fight against US Hegemonic Power. Did Xi just announce the birth of the New Axis of Evil? And, what might this mean for the future?
The conclusion from my World-System models is that the future forecasts for the New Axis of Evil all lead to collapse of the system (except for one worrisome scenario).
In prior posts (see the Notes below), I have looked at the issue of US Hegemonic Dominance and the economic performance of Russia, India and China. In this post, I will look specifically at how the three countries (RU, IN and CN) could interact with the current World-System.
