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