Guest blog: Robert Picciotto on randomised control trials
My recent blog on randomised control trials led to enthustiastic comments about Robert Picciotto's recent paper: Experimentalism and development evaluation: Will the bubble burst?.
I am delighted that Robert agreed to explain the main ideas in this guest blog. Robert ("Bob") was previously Director General, Evaluation, at the World Bank and is now a Visiting Professor at King's College, London.
Robert Piccioto on the RCT craze provides an excellent sense of history and measure to what they can and cannot do.
One thing though; not all those promoting them are micro economists. Most, in fact have little or no experience in quantitative research. A dangerous combination: hype and ignorance.
