Thus far, two DIBs have been completed and evaluated worldwide. There are others at various stages of design and implementation. Apart from the education-focused one in India, Peru has had a DIB on sustainable coffee and cocoa production. The final evaluation of the project said that most of the targets were met. A report by Brookings Institution assessed the performance of the first 38 SIBs globally. It found the following trends–more efficient and effective delivery of services; the development of strong monitoring and evaluation services; and higher degrees of collaboration. The report also highlighted a few shortcomings. While impact bonds are said to drive innovation, most of the 38 SIBs evaluated were based on well-established models. Moreover, there isn’t enough evidence to suggest that DIBs encourage private investment in social projects, because the investors’ money is finally paid back by the government or a philanthropist. We are also yet to see if interventions through SIBs have sustained impact on the lives on beneficiaries.
