It depends on the person, obviously, but here's my opinion as far as Gamma is concerned...
...
INTps are probably better at micromanaging their personal finances, and one reason that comes to mind is their negativism. Where an ENTj will think, "I want to go out to eat. It's probably not the wisest way to spend that money... that's okay, I'll make it up with extra profits/earnings," and INTp would assume the worst and use better judgment. Plus INTps don't have a Si PoLR. Also, INTps have ESFps for a dual... so they have to be the one in the relationship who is strict about impulse spending and avoiding excess.
So yeah, there are a few functions that come into play where money is concerned.
Se: Money = Power
Ti: sees and understands complex economic structures and models
Si: Careful/Caregiver types... able to see what is needed and what is excessive (may choose to live in excess anyways, but they're quite aware of it nonetheless), and they're probably less likely to take financial risks than Ni types as they are more concerned with the present and immediate future than they are the long term (I'm not sure how Si dominance plus a Te PoLR works in ISFps as I have not known any well)
Se PoLR types: Money = Power booooooooooooooo
Te: understand business structures and finances
Ni: more interested in the future than the present... more of a focus on the long term than the short term or immediate future
