The composition and implications of long term unemployment has been vigorously debated over the last year. The most recent informed commentary (skipping non-evidence based assessments [1]) includes Macroblog and SF Fed (earlier discussion here and here). Two conferences on the subject will be held at the University of Wisconsin-Madison, this Friday, and later at the end of April.
The magnitude of the phenomenon can be illustrated by inspecting mean unemployment duration, and number of unemployed over 27 weeks.
