World-System (1960-2010) Controlling the Argentine Economy I.

 


Economists* should probably admit that they don't know how to control the Economy. When an economist and politician such as Javier Milei gets elected as president of Argentina in 2023 and starts waving a chainsaw around as a symbol of cutting government, critics start to get nervous.

In a prior post (here) I found that Latin American Integration could stabilize the economy of Argentina. Unfortunately, Latin American Integration has been tried before and mostly failed, probably because Latin American has it's own problems with instability. The problem leaves me searching for other Geopolitical Alignments. In this post, I'll look more carefully at the ARL20 BAU model, that is, turning inward and concentrating on Business as Usual.

Why all the hand-wringing over Argentina? Millie has become the poster boy for the US Right Wing after giving a speech (with Elon Musk) at CPAC in 2025. The current Trump Administration and it's Department of Government Efficiency (DOGE), originally chaired by Elon Musk, seems intent on copying Milei's shock therapy. Unfortunately, or predictably, it seems that Milei's shock therapy has failed and will require a Bailout from the IMF and the US. So, it seems important to ask the general question about how (if at all) an unstable economy such as Argentina can be controlled?

The argument of Shock Therapy is that if we get the Government out of the economy, the Free-Market will take over and ensure prosperity. In other words, the free market will control the economy. If you have problems, it is because the market is not free of government interference. The "free market" assertion can be proven causally wrong (here).

From the standpoint of Systems Theory (where we have the best understanding of how to control systems), the first step is to establish an attractor path** among the competing Geopolitical models.


The attractor path (AP) for the ARL20 LAC Input model is presented above (dashed line) with the actual historical data (solid line). There are few serious deviations from the attractor pathexcept for AR3 (the definitions for the state variables are given in the Measurement Matrix below in the Notes) around 1975 and after 2000. However, AR2 and AR3 are Environmental-Unemployment-Globalization*** controllers and should be relatively stable over time (they aren't--why?).



The attractor path (AP for AR2 and AR3) for the ARL20 BAU model is presented above. Notice that it differs from the ARL20 LAC Input model AP. The period from 1980 onwards shows departures for both historical feedback controllers. For AR2=(LU+EF+KOF-CO2), unemployment, Ecological Footprint (EF) and Globalization (KOF) departures were very large relative to Emissions (CO2). For AR3=(EF+HDI+CO2-KOF-LU), departures for Globalization (KOF) and Unemployment (LU) dominated. 

The difference between the two time plots above shows that Latin American Regional World-System forces caused the departures and that the two historical feedback controllers (AR2 and AR3) were unable to correct the system within a period of decades (see the Eigenmodes for each model in the Notes below).

Also, in the DCM model (see the Notes below), these two historical feedback controllers interact: shocking AR2 increases AR3=(EF+HDI+CO2-KOF-LU);  shocking AR3 decreases AR2=(LU+EF+KOF-CO2). In other words, Globalization, Unemployment and Environmental degradation are used as historical feedback mechanisms to control the Economy. 

The effects take decades to work out. The historical feedback controller coefficients are weak (the off-diagonal elements in the System matrix below). The feedback effects in the full ARL20 BAU model (including growth components) are also weak.

Exercise 1: Strengthen the feedback coefficients in the ARL20 BAU model and see if you can better control the system.

Controlling how the system responds to Unemployment, Globalization, Environmental degradation will be a great deal more challenging than cutting Government spending, but better system control is needed in Argentina and a free market will not accomplish everything that is needed (here) while Latin American Integration is a long way off in the future.

In a future post (Controlling the Argentine Economy II) I will develop a formal control program for the ARL20 Model. For the time being, you can experiment with the  ARL20 BAU model yourself.


Notes

* Part of my Interdisciplinary degree at the University of Wisconsin--Madison (1981) was in Economics, so I should probably include myself in this criticism! It is one thing to control a System Model and another thing entirely to control an historical Macroeconomy. 

** The attractor path of a Dynamics Components State Space Model (DCM) can be computed with a free simulation starting from historical initial conditions (see Pasdirtz 2007). The free simulation that minimizes the AIC among competing Geopolitical models is considered the "best" attractor path, using some historical judgment when competing attractor paths are not well separated.

*** John Maynard Keynes pointed out, during the Great Depression, that Unemployment is not predicted with the Neoclassical Economic Model.
