PIRU’s Spring 2018 debate: “Do Social Impact Bonds work?”

Tuesday 17 April - Saturday 30 June 2018
London School of Hygiene and Tropical Medicine, Online

From April 17, in the run-up to the 3rd International Conference on SIBs in September, we are holding a 6-part, weekly blog debate, entitled “Do Social Impact Bonds work?” from cutting edge thinkers and researchers. We’re providing a global, as well as a UK, assessment of what SIB champions believe is a transformational approach to funding social services. Sign up and receive alerts for each blog by emailing

1. Emily Gustafsson-Wright of the Brookings Institution opened the debate on April 17, summing up the history, development and evaluation of impact bonds worldwide.

3. Katy Pillai, Big Issue Invest’s Director of Investment, lays out what matters to organisations focussed on prioritising social impact investment.

4. Then, Eleanor Carter and Clare FitzGerald, from Oxford University’s Government Outcomes Laboratory, set out what Whitehall wants to know.

5. An Asia Pacific perspective comes from Chih Hoong Sin of the UK’s Office of Public Management and Professor Ichiro Tsukamoto from Meiji University, Tokyo. The East, they say, has very different ideas about SIBs than the Western inventors.

6. Nicholas Mays, Alec Fraser, and Stefanie Tan, from PIRU, will wrap up the series, drawing on PIRU's own research. This final piece will set the scene for the 3rd International Conference on SIBs in September, organised by PIRU, RAND Europe, Newcastle University Business School and The Government Outcomes Lab at Oxford University.
