We explore the types of slow-roll inflationary potentials that result in
scalar perturbations with a constant spectral index, i.e., perturbations that
may be described by a single power-law spectrum over all observable scales. We
devote particular attention to the type of potentials that result in the
Harrison--Zel'dovich spectrum.
