Apologies for the light blogging. I fly to South Africa next week and I have a number of deadlines before then (applications for conferences, grants, etc), as well as several for when I arrive in Cape Town: exam questions due for external moderator, tutorials must go up on the web, must finish and upload lecture notes, presenting a seminar a few days after I arrive... I have several half-written research posts that I hope to complete soon. So, apologies, but more research on economics and experiments will come soon.
