Ah, interesting. That is likely a useful tool for analysis in a lot of ways, since all of these models are abstractions, after all. Some differences that I like about JMG's model, though:
1) the primary economy is not only the extraction of natural resources. For example, San Diego, California has low temperatures around 65 - 70 degrees F (~18-21 C) and high temperatures around 80-85 F (~27-29 C), some fog in the morning, and partial clouds clearing to sunlight by the afternoon all year round. Also, it's on the coast and has beautiful beaches. A huge amount of the wealth to the folks who live there and come to visit there rests on the lovely conditions, which don't need to be "extracted."
2) I think lumping all "services" together is almost equivalent to JMG's Tertiary economy, but there are a few wrinkles. For one, it doesn't account for any financialization happening in the manufacturing industry, necessarily - Ford makes a huge amount of money on the loans it offers directly to folks buying their cars. Basically, there's a bank inside Ford - does that get counted with the service sector, or manufacturing? Another big example is futures markets - resource extraction companies and agriculture engage in a lot of futures trading to hedge price risks for their primary business. Futures are definitely tertiary, but would they be counted as the services sector if being engaged in by ExxonMobil? For another, not all services are as liable to the positive feedback loops of financial markets - do things like barbers and lawn services get counted as part of the service sector? Or even snooty PMC work like management consulting is still subject to fairly-normal negative feedback loop corrections.
3) Hinted at with that last point, I find the heuristic that the secondary economy covers things subject to negative feedback loops, and the secondary economy those things subject to positive feedback loops to be very helpful, and make a lot of sense of tough questions.
As for your translation work, congrats on the progress so far, and good luck wrapping this one up! As Scotlyn said, it is nice to see a work that takes those complexities into account.
