Abstract
I consider a power-law inflationary model taking into account back-reaction effects. The interesting result is that the spectrum for the scalar field fluctuations does not depends on the expansion rate of the universe and that it result to be scale invariant for cosmological scales. However, the amplitude for these fluctuations depends on .
