What we know of clan society also points to the fact that all the industrial engineering (that I,ve mostly seen qualified by the broader term "buisness managment" in english) concepts following the realization in the 1970s that overproduction (mind you, some of those concepts were already being developped in the 1920s) was a thing were pretty influencial in the way the clans inner workings were tought out.
Now my introductory courses on the subject get further away each year and my memory isn't the best, but 2 or 3 examples just to give a general idea...
WoR describes that most Clans don't even prodcue enough to last them a month.
This part underlines how much "Just in time production" is ingrained in the clans conception of economy. Realistically, this doctrine often produces huge bottlenecks and other distruption, but such things can be ignored for the purpose of the BTU.
"The clans abhore waste" is a well known fact. In the workings of this we see the strong influence of "lean manufacturing/management". Of course, the whole trialing aspect adds another layer, but consider all that must be put in place when a factory or a mine changes hands. Suddenly, you have the whole supply chain to be completely reworked for the 2 belligerents.
And not necessarily purely ECONOMICAL but having an influence on it, the parallels one can make between clan society and big companies (some of them having become "states within the state") like samsung is quite troubling. Now, as I said, I only got the introductory courses and my memory is faulty so I can't elaborate that much anymore, but the whole "manage it like a sect, notably by encouraging a breaking of the family for a greater integration whithin the company" (mind you that's my interpretation of it, but the teacher looked horribly uncomfortable when I underlined this and didn't reply) thing, notably, allows to see how you can make links.
*add-on*
Now I fear this isn't a good day for me as far as clarity of thought is concerned and I'm writing this through chores, but I've always found this a very interesting subject, so a few more things while trying not to skirt too close to rule number 4.
As has also been pointed out, the clans have a centralised economy (with "dark zones", of course). So take the sea foxes, whom seem to bring clan economics to its logical conclusion. There current method can be linked to a current "mostly centralized economy" that holds much sway in the run of things internationally and which doesn't shy away from overproduction for a variety of reasons.
Through their overproduction and subsequent liquidating of assets once the stocks become too great, they can heavily influence the international market when they do liquidate. Then look at what's happening with the sea foxes growing hold on many types of markets.
Of course, the sea foxes are distinct in their running of things, but they still use the same basis. And this must have been true since the clans caught their "air d'aller". After all, each clan is but a "state within the state" of the greater clan organization. On top is the "warrior democracy" reminiscent of many dark age "barbarian" hordes, underneath is the whole corporate entity, for each clan is but an armament company...heck, trueborns are basically a product to be consumed by said corporate entity...so then, whom is truely in charge? And that osmosis inevitably affects the conception of the economy.
Wish I could be more concise here...but I guess this is enough to draft a drift.
Ah yes, last thing to support my extapolated drivel...consider Jordan Weisman, consider the other flagship FASA product that is shadowrun and its (from what I know, haven't been in contact with it much) focus on corporate structures and their stranglehold on sociey.
