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

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. A whole series of laboratory experiments has detailed the gap in competitiveness between the average woman and the average man, even when women are just as good, if not better 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
