Like Jessica said, not well-defined. UDT only solves games where all players have the same utility function, it pretty much just extends utility maximization to games with copies. I’m not sure that general game theory with bargaining can ever be reduced to decision theory, or at least it will take some new idea which is most likely orthogonal to UDT. I spent a lot of time trying to find such an idea and failed.
How does bargaining work in UDT? Are there any posts on this?
