iHEA's conference is kind of big deal in health economics: it's usually very big, with lots of sessions and lots of people participating. I have been to a few, both sides of the Atlantic and they are usually very good. This year it's in Milan (I think building on the Expo) and tomorrow I'm off to go. I'll be talking about the Structural Zero Costs model (not super-new $-$ I've mentioned this already here, here, here and here) in an interesting session on Tuesday.
It's always a bit weird, I think, going to conferences in Italy (or in London, for that matter) $-$ I think the spirit of being "away" at the conference kind of goes away. Still... I'm looking forward to some of the sessions!
