  We study the cosmological evolution of a N = 1 supergravity model, dual to a
higher derivative supergravity model coupled to scalar fields so that in the
Einstein frame the model is ghost free. We find that this model admit slow roll
inflationary solutions showing essentially two-field inflation. The
cosmological parameters calculated for this model lie in acceptable range with
corrections of the order lnN/N, N being the number of e-foldings, compared to
the Starobinsky inflation model.
