Abstract
We propose a general mechanism for stabilizing the dilaton against run away to weak coupling. The method is based on features of the effectiv e superpotential which arise for supersymmetric gauge theories which a re not asymptotically free. Consideration of the 2PI effective action for bilinear operators of matter and gauge superfields allows one to o vercome the obstacles to constructing a nonvanishing superpotential.
