I love the idea of this. Two comments though.
1. You might want to think about how you would include the financial and insurance services. Much of the wealth of the UK is based entirely on this sector which produces few discernable "products", but takes excess financial resource and makes it work more efficiently. Allegedly.
In your terms, this might be an alternative human resource model that takes multiple units of capital with 1 unit of infrastructure to generate additional capital, and that capital is then available for export in return for importing goods and agriculture.
2. Also don't forget Leisure Tourism and Hospitality. On Rich High Techworlds this is likely to be a hugely significant sector, as they use technology to reduce their working day and/or increase their efficiency, creating more time and free cash for non-productive activities.
In terms of your model, there may be an "acceptable wealth" point where efficiency is generating such a return on human resource / production that excess is not used to generate more production but to increase leisure time.

I'm not working at a level of detail that makes financial industries or tourism a concern. In this model, capital is purely the tools of production and not financial backing. The finance industry creates no 'wealth', aka goods that have value. They only transfer paper around.
The paper is worth only as much as the goods it represents. When the amount of paper does not match the value of the goods, you can get inflation ( Zimbabwe ) or other financial $%#% like the US's housing bubble.
Tourism/leisure is abstracted by consumer demand which might be for televisions or beer or souveniers... consumer goods produced by light industry.
Free time is not worried about... I don't care if the worker makes the product over the course of one day, or one hour.
Both of these areas are abstracted as 'other' economic sector. They produce no wealth/goods but the population themselves are goods which other sectors have a demand for. .. and they themselves also have a demand for food/goods/resources/services.
If there is more supply than demand, the prices will plummet and the sector's return should plummet too. If there is more demand than supply, prices will skyrocket and 'happiness' will eventually start to fall....fall too far and riots/revolution might occur ( I haven't got that far with this yet.
I"ll get things worked out in a spreadsheet eventually.
They fun part will be when variable demand is factored in.
" Last year, blue rocks were hot...now I can't give them away "
< okay..that's a bit extreme as supply/demand rarely swings that far that fast. >

All this because I was curious about trade volumes between worlds.
and no, I'm no economist......
