We study quantum corrections to an inflationary model, which has the
attractive feature of being classically scale-invariant. In this model,
quadratic gravity plays along a scalar field in such a way that inflation
begins near the unstable point of the effective potential and it ends at a
stable fixed point, where the scale symmetry is broken and a fundamental mass
scale naturally emerges. We compute the one loop corrections to the classical
action on the curved background of the model and we report their effects on the
classical dynamics with both analytical and numerical methods.
