  In this paper I develop and characterize a random attention model with
unobserved reference alternatives. The decision maker pays attention to
different subsets of the available set of alternatives randomly. The reference
alternatives are exactly those alternatives that are always paid attention to,
i.e. they are attention-privileged and these alternatives are supposed to be
unknown to the outside observer. The characterization allows for a complete
identification of the reference alternatives and a coarse identification of the
underlying preferences. I then restrict the model by considering the
independent random attention function and provide a complete identification of
the underlying preferences as well.
