  We introduce the concept of mean field games for agents using Forward
utilities of CARA type to study a family of portfolio management problems under
relative performance concerns. Under asset specialization of the fund managers,
we solve the forward-utility finite player game and the forward-utility
mean-field game. We study best response and equilibrium strategies in the
single common stock asset and the asset specialization with common noise. As an
application, we draw on the core features of the forward utility paradigm and
discuss a problem of time-consistent mean-field dynamic model selection in
sequential time-horizons.
