Old-person observation: the establishment of six years as a normal length of an economics Ph.D. is bad, because behaviorally it makes it a lot easier to waste years 2 and 3 not trying to write a job market paper. Individually, people are better off taking 5 years as the goal.

@ben_golub Have JMPs gotten better as a result of students coming in with pre-doc experience and staying 1-2 years longer? My sense is that the top 5% of JMPs have gotten better but the median is essentially unchanged…?

I know a person who runs lots of field experiments. Literally prize winning stuff. Their estimate of how likely it is for a field experiment to happen successfully once a partner firm or organization agrees: 10% (Success here means actually carried out, correctly)

“The main reason why you give a seminar is to advertise the work. Originally, I thought the point was to get comments, but I now believe it’s the networking; people get to see the work, they get to understand it, and you get to clarify what they don’t understand.” Daron Acemoğlu
