I don't have any publications on the matter as I've destroyed all my cult stuff, but having been a jw in a welfare state (Australia) I have a lot of first hand experience with this topic.
In short, yes, jws can receive benefits. There are many benefits in Australia and jws can receive unemployment if they're truly unemployed (not doing cash-in-hand work on the side), disability, single parent, family, medical and study allowances. I myself have been on unemployment, medical and student while a jw, and it was all fine "theocratically".
Where it is considered unacceptable is if one pioneers while on unemployment, because technically they should be supporting themselves as the bible says to. Someone on unemployment technically should not have their pioneer application accepted ie they are not supposed to go on the dole to pioneer because it's a bad witness.
