How do we know what works? Professor Michael Woolcock

How can we assess the impact and scalability of complex interventions? Why use mixed methods? How can we tackle hubris among economists at the World Bank? The wonderful Professor Michael Woolcock (Lead Social Scientist at the World Bank) makes the case for mixed methods. This discussion draws on his chapter, forthcoming in Michiru Nagatsu and Attilia Ruzzene (eds.) (forthcoming) "Philosophy and Interdisciplinary Social Science: A Dialogue".
