Determiner raising and scope shift

Whether quantifier scope is regulated by movement or not has been debated for more than two decades, and this issue has become especially important in the minimalist framework. This article provides a novel argument for the existence of a scope-marking movement operation on the basis of what can be called the split-QP construction in Japanese. It is shown that the construction involves overt movement of quantificational determiners, whereby their scope is visibly marked, and that the movement operation is subject to economy so that it may apply only if it yields scope shift.
