We propose a mechanism by which density perturbations δρ/ρ∼ and a baryon asymmetry /s∼ can naturally be generated in any realistic supersymmetric theory. By ‘‘naturally’’ we mean that the coefficient λ in the usual toy-model inflationary potential V=λ is related to the superpotential Yukawa coupling which generates the electron mass. We identify a nine-parameter ‘‘quasiflat’’ direction which generates δρ/ρ through chaotic inflation and which leads to an Affleck-Dine valley (flat direction) where primordial baryogenesis occurs.
