  We consider no-scale supergravity inspired scenarios, emphasizing the
possible dynamical determination of the soft supersymmetry-breaking parameters
as triggered by the radiative corrections that lift an essentially flat
tree-level potential in the hidden sector. We (re)emphasize the important role
played by the scale-dependent vacuum energy contribution to the effective
potential for the occurrence of consistent no-scale minima. The most relevant
input parameters are introduced as $B_0$ (the soft breaking mixing Higgs
parameter) and $\eta_0$ (the cosmological constant value at high energy)
instead of $\mhalf$ and $\tan \beta$, the latter being determined through a
(generalized) potential minimization at electroweak scales. We examine the
theoretical and phenomenological viability of such a mechanism when confronted
with up-to-date calculations of the low energy sparticle spectrum and with
present constraints from the LHC and other observables. The tight dark matter
relic density constraint for a neutralino LSP scenario can be considerably
relaxed for a gravitino LSP scenario possible in this framework.
