<P>While much foreign aid achieves commendable goals, some is ineffective. In this volume, Clifford Zinnes argues that a donor's intrinsic informational limitations on the local context as well as inability to control the progress of interventions mean that lack of success is not rooting in insufficient funding but in maladapted institution designs of interventions that don't foster local ownership. He indentifies and assesses a newly emerging class of foreign aid delivery that promises to overcome these obstacles. The approach is based on "prospective inter-jurisdictional competition" (PIJC). Beneficiary groups ?often local-level governments, supported by their private sector and civil society ?act as teams and compete against each other under explicit predefined rules and objectives to design and implement interventions under their own aegis to achieve the highest quantitatively measured performance, either relative to others ("tournaments") or against a preset benchmark ("certification"). Teams that cooperate internally are the likeliest to win the rewards, which, aside from the longer run benefits of the intervention itself, might include more substantive financial or technical assitance from the sponsor.</P><P>Since only groups serious about reforming choose to play, Zinnes says the incentives generated by the ensuing "race-to-the-top" competitiion create local ownership, encouraging recipients to draw on their own knowledge. Moreover, since all teams that compete ?and not just those who "win" donor rewards ?benefit from their own reform efforts, he argues that this approach can leverage aid resources more than a conventional bilateral aid agreement. Zinnes presents a dozen recent applications of the approach, including those sponsored by the World Bank, USAID, the United Nations, the Ford Foundation, and others. He also recommends improvements and ways to scale up PIJC-based projects in applications ranging from protecting the environment and reducing red tape through to raising literacy and co-opting warlords.</P>
