shell-script scripting variable posix assignment

                          Are

    x=$y

and

    x="$y"

always equivalent? Didn't know how to search for this. So far, I've always been using x="$y" to be "on the safe side". But I used x=$1 at one point and noticed that, apparently, I don't even need the extra double quotation marks.

Where is the behavior defined in The Open Group POSIX document?
