  A new scalar-tensor theory of gravity induced by dynamically broken scale
invariance is proposed, and its cosmological implications are discussed. It is
found that the model admits an inflation via the Hawking-Moss bubbling, but the
inflation rate remains undetermined due to the strong gravity limit. In light
of this, scale-invariant metric perturbations having a dominant tensor
component can be generated without slow-rollover. In addition, the deviation
from the standard hot big-bang is vanishingly small after inflation.
