Abstract
We discuss the main cosmological implications of considering string-loop effects and a potential for the dilaton in the lowest order string effective action.Our framework is based on the effective model arising from regarding homogeneous and isotropic dilaton, metric and Yang-Mills field configurations.The issues of inflation, entropy crisis and the Polonyi problem as well as the problem of the cosmological constant are discussed.
