  The fate of shift-symmetries in effective string models is considered beyond
tree-level. Such symmetries have been proposed in the past as a way to maintain
a hierarchically small Higgs mass and also play a role in schemes of
cosmological relaxation. It is argued that on general grounds one expects
shift-symmetries to be restored in the limit of certain asymmetric
compactifications, to all orders in perturbation theory. This behaviour is
verified by explicit computation of the Kaehler potential to one-loop order.
