A globally supersymmetric model of inflation will not work in a generic supergravity theory because the higher order, nonrenormalisable supergravity corrections destroy the flatness of the inflaton's potential. In this talk I derive a form for the Kahler potential which eliminates these corrections if W = ∂ W / ∂ φ= ψ= 0 during inflation (where W is the superpotential, the inflaton is contained in φ, and ∂ W / ∂ ψ≠ 0 ). I then point out that Kahler potentials of the required form often occur in superstrings and that the target space duality symmetries of superstrings often contain R-parities which would make W = ∂ W / ∂ φ= 0 automatic for ψ= 0.
