Social Impact bonds (SIBs) have attracted much attention in the aftermath of the financial crisis. They have been
implemented in a number of countries as they seem to be an attractive proposition for financing the delivery of social
services.
However, SIBs remain a fairly new financial instrument aiming at social impact with limited evidence regarding
their results. Therefore, further analysis is needed in order to develop a robust evidence base.
SIBs are complex instruments. They involve multiple stakeholders coming from different sectors. Time, technical
expertise and commitment to collaborate are indispensable in order to establish a SIB.
SIBs have been costly instruments so far. They have entailed significant transaction costs that stakeholders
should consider before embarking on them. Policy makers should evaluate carefully what is the value added for
implementing a SIB for a policy intervention compared to a more traditional approach. However, transaction costs are
expected to drop as more SIBs develop and there is a streamlined process for establishing them.
Rigorous methodological design for identifying measurable social outcomes and appropriate target groups is of
utmost importance in order to avoid perverse effects, such as “creaming”, “parking” or “cherry picking”.
SIBs may be an opportunity to nurture a culture of monitoring and evaluation in social service delivery.
Independent and robust evaluation could benefit all stakeholders as it may identify what works well in SIBs and what
does not as well as unintended consequences- positive or negative.
SIBs intend to roll over the risk from the government and the service providers to investors. Yet, capital protection
and guarantee mechanisms as well as early termination clauses of the SIB contract may be in place mitigating the risk
assumed by investors.
Ensuring continuity of social service delivery by the public sector is indispensable for vulnerable groups and
citizens. Therefore, SIBs could be more appropriate as a complementary and not core mechanism for social services
delivery.
