Not clear. You are assuming that the agent believes that you will be
able to pay you $1/day, and that it believes the value of $1 remains a
constant. Both are probably false for a reasonably intelligent agent.
And it also needs to believe that it can't invest the money in other
ways for a better return. Etc.
If you are limiting the environments in which is it operating to
extremely simple ones, or the agent is very naive about the external
environment, then it might agree to your terms. And if the agent is
very trusting and significantly less intelligent that you, it might
agree to your terms. But if the agent is living in an environment that
maps reasonably onto the world that we live in, then I doubt that it
would believe that YOU would immortally honor the contract.
There's more things going on in this decision that just it's belief
about it's own immortality. And to even have the concept as more than a
label it's going to need a lot of connections and information about the
external world. So I'm not certain that the limited agent described in
the prior paragraph could actually exist (and have actual beliefs about
immortality...at least rationally based ones).
