What the HIV prevention gel trial failure implies for trials in economics

For the World AIDS Day, there is a sign at the World Bank that states that taking ARVs reduces rate of HIV transmission by 96%.

Guest Post by Ken Leonard: Gender and Biological Differences between the Sexes

Women are less likely to occupy the top paying jobs in developed economies, in part because they are less competitive than men.

So I come back from vacation to find out that I was part of a randomized experiment in my absence.   No, this had nothing to do with the wonders of airline travel in Europe (which don’t add that frisson of excitement through random cancellations like their American brethren), but rather two of our co-bloggers trying to figure out if the blog actually makes people recognize me and Jed more (here are links to parts

In a working paper on the new LSMS-ISA (integrated surveys for agriculture) website, Brian Dillon describes the experience using phones in a research project he was working on with Diego Shirima, Geofrey Mwemezi and Msafiri Msedi.   (You can also find a published version of this paper
