I will discuss the possibility of obtaining vacua with spontaneously broken supersymmetry and non-negative cosmological constant in the moduli sector of string models, as well as the possibility of realising slow-roll inflation. I will show that there exist some simple conditions for this to happen which depend only on the Kahler potential. I will then analyse the implications of these conditions through some examples.
