On the other hand, if the technique used to provide the funds limits the willingness at the sub-national level to raise its own revenues, and increases its dependence on transfers, laws and legislation can serve to widen the funding gap. With respect to the capacity gap, legislation can be used to help establish frameworks or parameters that build sub-national capacity by allocating competences and resources. If it helps to define roles and responsibilities clearly, legislation can overcome problems of duplication and overlap. Assigning tasks, rather than allocating funding, can be a better way of managing problems of resource allocation.
