Aid fragmentation is widely recognized as being detrimental to development outcomes. We re-investigate the impact of fragmentation on aid effectiveness in the context of growth, bureaucratic policy, and education, focusing on a number of conceptually different indicators of fragmentation, and paying attention to potentially heterogeneous effects across countries. Our results demonstrate the lack of robustness and any systematic pattern. This stresses the importance of questioning the sweeping conclusions drawn by much of the previous literature.
JEL codes: F35, O11Keywords: aid effectiveness, fragmentation Acknowledgements We are grateful to three members of the DAC secretariat, Fredrik Ericsson, Hubert de Milly, and Suzanne Steensen, who constantly supported us in the context of a prior study for GIZ (Dreher and Michaelowa 2010) that served as a basis for this broader research. The initial study also enabled us to carry out a number of interviews in two very different recipient countries that significantly influenced our ideas on how to approach the questions addressed here. We thank Marina Mdaihli (GIZ Ouagadougou) and Birgit Erbel (KfW Hanoi) for arranging interviews in Burkina Faso and Vietnam respectively, and we are indebted to all those who were willing to spend their scarce time with us to the benefit of this study. We finally thank the participants of the GDI-conference on "Fragmentation or Pluralism? The organisation of development cooperation revisited," Bonn 2013, for helpful comments and Bastiaan Visser for proof-reading.
