The RCT Bubble

Is it really a bubble? Whilst there has been rapid growth of impact evaluations of aid projects across agencies, and plenty of internet chatter, the vast majority of aid spending still does not get properly evaluated.  
For example, while there has been a substantial growth in impact evaluations of the World Bank development projects, only 8.8% of World Bank investment loans in 2009/10 had an impact evaluation. In 1999/00 the proportion was 2.4%.  ----- Martin Ravallion, World Bank Research Director
