Abstract: (Elsevier)

We study quantum-string propagation in cosmological backgrounds pointing out the possible emergence of Jeans-like instabilities. We also determine under which conditions the universe expands, when distances are measured by stringy rods. Examples include Friedmann-Robertson-Walker (FRW) and de Sitter metrics, as well as a linear-in-time dilaton (constant background charge). A time-dependent dilaton does not give an expanding universe in the above sense, while FRW or de Sitter metrics usually do. For the latter case (inflation), instabilities occur for large enough Hubble constant.
