Gold-silver ratio over 20 years in phase space

Today's chart is the rate of change of the gold-silver ratio plotted against the ratio itself over the last 21 years (beginning of 1994 to the end of 2014).


The major features are three regions of stability--one in the low 50s, one in the low 60s, and one in the mid 70s.

For stackers of both gold and silver, the lesson here is to buy silver when the ratio is in the 70s and trade it for gold when it is in the 50s (or on rare opportunities when it is lower, as in 2011). I traded about 200 oz of silver for gold at about a ratio of 45 back then, and in hindsight wish I had traded a lot more.

Concentrate more on gold when the ratio is in the 50s. Sometimes this is difficult because of all the voices clamouring for silver to "go to the moon", but that never quite seems to happen, unless the moon is $50.

Multistability in the political world

In this blog I have tried to show that economic systems behave very like complex natural systems, which are often characterized by multistability. These demonstrations have been easy because of the data available from economic systems.

Political systems may similarly exhibit multistability. But this is not so easy to demonstrate in phase space.

Rosie Dimanno has a recent opinion in the Toronto Star about the ongoing horror in Afghanistan. Unfortunately, she draws the wrong conclusions, stating that the internecine warfare amongst groups of Muslims is occurring because "we" are withdrawing our troops. According to Rosie, all would be well if only the West would continue its benevolent humanitarian interventions in Afghanistan and other places around the world.

She doesn't pause to consider--why all this violence? Were all these countries this violent before the foreign interventions? How was Afghanistan before all the western intervention--which goes all the way back to the Russian invasion (if not earlier)? The pictures in the above links suggest it was a pretty nice place.

The current state of Afghanistan is completely different from the above earlier version of the country. What changes a peaceful place into one wracked by war, kidnappings, and all forms of extremism?

I believe we are looking at a state change much like we observe in complex natural and economic systems. Most systems find themselves in some stable state (which one is a function of the entire past history of the system). External forcing mechanisms (often in conjunction with internal mechanisms) may drive the system from its zone of stability.



Once the system leaves an area of stability, it tends to behave chaotically until it settles in another region of stability (or perhaps the same one).

What may have happened in Afghanistan is that western intervention drove the social system from its former stability and into a chaotic regime. Ordinarily, we would expect the system to evolve to some other stable state, but perhaps the ongoing interventions have kept this from happening.

It isn't clear if the social state in Afghanistan has switched to a new and very undesirable stable state, or whether it is winging through the realm of chaos. Trying to drive the system to a particular realm of stability is difficult--we have no theoretical framework for success. For this reason, it is typically better not to intervene in the first place.

Year of the Sheep

Happy New Year. 恭禧发财.



As it is the Year of the Sheep, sheep are a common motif in displays around Zhengzhou.






And superheroes.




I don't know what everything represents.




And the last two a blast from my former home.

Harper looks serious

. . . in the photo on his Facebook page.

Very serious, very leader-like, as he condemns ISIS for beheading 21 Coptic Christians.

Does he consider his own role in the debacle? Perhaps if he hadn't been so gung-ho to murder in favour of progressivist "R2P" bullshit, he wouldn't have broken Libya, and there'd be a whole lot less killing going on.

But of course, in his mind, there is no connection between his past actions and the present consequences, which shall go on and on.
