Paul Krugman has the definitive word on econ blogging
the journals ceased being a means of communication a long time ago – more than 20 years ago for sure. New research would be unveiled in seminars, circulated as NBER Working Papers, long before anything showed up in a journal. Whole literatures could flourish, mature, and grow decadent before the first article got properly published – this happened to me with target zones back in the late 1980s, where my original 1988 working paper had spawned a large derivative literature by the time it actually got published. The journals have long served as tombstones, certifications for tenure committees, rather than a forum in which ideas get argued.
Since there’s some kind of conservation principle here, the fact that it’s easier for people with less formal credentials to get heard means that people who have those credentials are less guaranteed of respectful treatment. So yes, we’ve seen some famous names run into firestorms of criticism — *justified* criticism – even as some “nobodies” become players. That’s a good thing! Famous economists have been saying foolish things forever; now they get called on it.
Rest here. Interesting all through.
