In a Ginzburg-Landau model of induced gravity based on the Lagrangian density L=-^2R/2-^_/2 - (^2-v^2) ^2/8, we investigate the semiclassical evolution of from to the spontaneous-symmetry-breaking minimum =v v^-1/2 (8) ^-1/2. We show that for, 1 the transition is inflationary, both in the case that the initial value of =0 (``ordinary new inflation'') and in the case that the initial value of (Linde's ``chaotic'' inflation). The value of required to ensure density inhomogeneities of the proper size is dependent and typically 10^-12.
