If you see a disproportionate number of geeky looking folks around Portland this week making painfully bad jokes about things like optimality or discount rates or the like (and if you are a restaurant server and find your tips rather skimpy this week), it's because a fairly major economics conference is in town.
The Western Economic Association International's Annual Conference in in Portland at the Downtown Hilton this week, from Wednesday to Saturday. Lots of cool presentations if you are a über-nerd, and even some if you are not. If nothing else, as an anthropological exercise, you can wander near the Hilton and stare in wonder at the culture that is economics.
You have been warned.
