     Hi Pieter,

     I ran your model. Congratulations from an old guy who builds models.

     Certainly your work allows you to reason about the effects of 
choices at the micro level.
Two remarks, without having given it too much thought: (i) at the micro 
level, you could add the circuit of wages producing taxes and 
consumption and savings and arising from private sector labor but also 
from government employment; (ii) at the macro level, excess imports 
correspond to negative savings, but also produce a flow of capital that 
buys government debt.

     Greetings, Pietro from Italy
