Marion Ledwig's thesis appears to be an overview of Newcomb's Problem from 2000. That's from before the disposition-based decision theory I referenced was worked out - and there's minimal coverage.

Are you suggesting that there are some proposed solutions to the problem of building a decision theory that "does the right thing" somewhere in there, that pre-date disposition-based decision theory?

The main thesis there (in the section "Newcomb's Problem as a Game against Nature") seems to go against what many people think here - and is more along the lines of CDT.

Anyway, since it's a 300 page thesis, perhaps you would like to be more specific.

Or maybe you are just waving in the general direction of the existing literature. In which case, I fail to see how that addresses my point.

"Paradoxes of Rationality and Cooperation" dates from 1985. That seems rather unlikely to have relevant coverage either. Again, it came too early - before the first attempts at a solution that I'm aware of.
