RT Monograph SR 00 A1 Auriol, Emmanuelle A1 Miquel-Florensa, Josepa T1 Taxing Fragmented Aid to Improve Aid efficiency YR 2015 FD 2015-08-31 VO 15-600 SP 36 K1 Aid fragmentation K1 incentives K1 multi-principal K1 Development AB We present a model with two donors-principals that provide funds to a unique recipient-agent. Each donor decides how to allocate his aid funds between a pooled and a donor specific unilateral project. Both principals and the agent value the output produced with the principals' pooled and two unilateral funded projects. However the donors have a bias in favor of their own unilateral project, which leads them to over-invest in these projects. The agent establishes a tax on the unilateral projects, which acts as a protection measure against biased allocation by the principals. The optimal tax imposed by the recipient on unilateral projects varies depending on the total amount of aid provided by the donor and on the productivity of his unilateral project. We present empirical support on the donors' preferences for unilateral projects, and how allocations and fragmentation are affected by recipient's characteristics.
