· Essential reading this week: The Boston Review has an excellent feature on early interventions to promote social mobility, with the lead article by Jim Heckman . I never realized quite how small the samples of the famous early childhood studies are – treatment group of 58 kids in the Perry Preschool program and 65 in the control group.
· How foreigners affect survey responses on the CSAE blog  – “We found that participants acted more generously – an average increase in giving of 20% – in villages where the white researcher was present.”
· Tim Harford  discusses the results from “ one of the world’s largest ever randomized trials” involving almost 2 million people in a Community Driven Development program in the Democratic Republic of Congo – money made it where it was meant to go, but little in the way of development results to show for it seems to be the bottom line.
· Call for papers  for Oxford’s CSAE annual Africa conference

· The Guardian’s development network summarizes a Kenyan cash transfer  study that finds a cash transfer program for orphans and vulnerable children reduces sexual activity among teens – I’m looking for Berk to give his take on the study in due course…
· Sample size jealousy: researchers ran an experiment on Facebook  with 61 million people, every single adult in the U.S. who logged onto Facebook on election day 2010 took part in the experiment – which looked at whether seeing your Facebook Friends have voted causes you to be more likely to vote (yes).
