From the preface:
Development Impact Bonds are being explored at a time when tightening public budgets and the shortcomings of traditional funding models have fueled a movement towards results-based approaches. The last decade has seen donor money shift towards newer, more adaptive and more flexible results-based mechanisms such as Advance Market Commitments and GAVI Immunisation Support Services. However, operational, financial and political constraints have limited their widespread adoption. Development Impact Bonds are an innovative instrument that could help overcome some of those obstacles.
We hope that this report will stimulate a dialogue among donors, partner governments, investors and service providers to consider and test the opportunities that these rich collaborations might bring.
