State Space Models

All state space models are written and estimated in the R programming language. The models are available here with instructions and R procedures for manipulating the models here here.

Alternate Geopolitical Alignments for Israel

 



What is the "best" Geopolitial Alignment for Israel? In this post, I look at some options: (1) None (Business-as-Usual, BAU, or Muddling Along, Random Walk, RW), (2) Alignment with the Region (Middle East North Africa, MEA), (3) Alignment with the World System (W) or (4) Alignment with the US. Google AI reports the Conventional Wisdom:


However, the first question is "what do we mean by best?"

In terms of Systems Theory, the question is whether a Steady State Economy in Israel (and the Middle East) would be best or whether the Neoclassical Economic Dream of unstable, endless exponential growth is best. I cannot answer the question for policy makers even though endless economic growth is not possible on a finite planet. We just have to keep the question in the back of our minds as we are evaluating Geopolitical futures for Israel.

Another more specific question is whether we are interested in the short- or long-term? In the short-term, Israel is at War with Iran and currently aligned with the United States. So, the Long-term Attractor Path is of more interest since the path is unknown.

Using various IL_L20 Models, I ran five alternatives plotted in the graphic at the start of this post.  The best long-term model, which provides short-term exponential growth and long-term stability, is the IL_L20 MEA Input model (see the Notes below).

The second-best option is the IL_L20 BAU Model, but it is unstable. As a policy counterfactual, consider stabilizing the BAU model (see the Notes--stability involves reducing growth rates). Under a stable BAU regime, the IL_L20 Model reaches a Steady State around 2150 and provides over a century of continued growth for Israel.

Interestingly enough, alignment with US input is not best because the model is quite cyclical (see the Phase Diagram of the IL_L20 US-Input Model here). The prediction from US-Input model is that, after the War with Iran, the US will direct strategic attention elsewhere (back to Asia?) as happened after past Peace Agreements.






Notes

More readings:
You can run the IL_L20 model, written in R-codehere. Instructions in the code show how to stabilize the system. Other models for the Middle East and North Africa are available here.

IL_L20 Measurement Model


Three Component State Variables explain over 98% of the variation in the indicators: IL1 = (Overall Growth), IL2 = (LU - KOF - EF) Unemployment Controller and IL3 = (EF + L  - KOF - HDI) Environmental-Labor Controller.



IL1 AIC Statistics


The AIC Statistics are all closely grouped meaning that there is not one, dominant Geopolitical model.

IL_L20 BAU Model


The IL_L20 BAU Model is unstable and cyclical.

IL_L20 BAU Model Controlled


The IL20 BAU Controlled Model is stable and cyclical.




The historical time plot for the IL_L20 BAU Model is presented above.


The historical time plot for the stabilized IL_L20 BAU model is presented above.


IL_L20 MEA-Input Model


The IL_L20 MEA-Input Model provides the best attractor path. However, it seems quite unlikely that a stable Middle East will happen anytime in the foreseeable future.

Future Scenarios for Iran




In an Opinion piece for the NY Times How Does This End? Four Scenarios for What Comes Next With Iran, Bret Stephens argues that there are four likely future scenarios for the War in Iran: (1) Regime Change, (2) Regime Modification, (3) Both sides declare 
victory and (4) the Realistic Path, US seizes Kharg Island (see the video above which argues that the "Realistic Path" is a trap). These scenarios are all relatively short-term.

My interests are in more long-term Geopolitical Alignments that might benefit Iran. It seems that most of the World-System has abandoned Iran. Russia, China, and the EU are all sitting on the sidelines while the US and Israel continue an Air War. And, my simulations with the IR_LM model show that leaving Iran to "go it alone" (the Business-as-Usual or BAU model) produces the best future prospects (see the simulations here). The US and Israel seem intent on not letting the BAU Scenario go forward.

I asked ChatGPT about the Geopolitical Consequences of the current US-Israel-Iran War:


I can investigate the effects of a Global Oil Shock by using the WL203 Model.



The third component state variable (see Notes below) is dominated by Oil Prices. A large one standard deviation shock to the W3 component (an Oil Price Shock and associated effects: Wheat Prices, Oil Production and Ecological Footprint) produces the shock decomposition above. Overall growth in the World System (W1)  takes a negative shock that is never fully recovered. The same is true for the W2 state variable (an Environmental Controller); the negative shock is never recovered. Eventually, however, Oil Price Controller (W3) returns to the attractor path.
