Calculations are performed in four dimensional effective supergravity. Constraints on closed string fields in a type IIA construction are given. The particular case of stabilization by stringy instanton effects in a type IIB model is considered.17 pages, no figures, LaTeXHigh Energy Physics - Theorytext
