They are generated by a particular phenomenon for knowing the behavior of the involved geographic entities. In order to disambiguate...

This paper brings the aid effectiveness debate to the sub-national level. We hypothesize the non-robust results regarding the effects of aid on development in the previous literature to arise due to the effects of aid being insufficiently large to measurably affect aggregate outcomes. Using...
