  We study the dynamics and predictions of a new emergent-universe model
recently derived within Quantum Reduced Loop Gravity and based on the so-called
statistical regularization scheme. These effective geometries show a dynamical
transition from a stationary spacetime, with nearly constant scale factor at
very early times, to a late-time semiclassical phase well approximated by a
classical Friedmann-Robertson-Walker spacetime. We show that this is always the
case when the matter content is a minimally coupled scalar field subject to a
quadratic potential, including the massless case. Besides, a finite period of
(nearly) exponential expansion in the semiclassical region can take place.
Hence, we incorporate cosmological scalar and tensor perturbations, with a
well-defined dynamics, and compute their power spectra at the end of inflation.
We show that they are nearly scale invariant up to some scale where scale
invariance is broken. Besides, they show qualitative differences with respect
to the bouncing scenario of Loop Quantum Cosmology at scales where the scale
invariance is broken. Nevertheless, the tensor-to-scalar ratio remains
approximately constant even for modes well affected by the background
evolution.
