The April 2009 issue of The Freeman is chock-full of excellent articles. I'll mention here three, because each is especially relevant to the current economic downturn and the question of how best to analyze it — and how best to deal with it.
– Roger Garrison on "The Trouble with Keynes"
– Peter Lewin on "Recycling Discredited Ideas"
– Mario Rizzo on "A Microeconomist's Protest"
(Mario articulates far better than I have been able to do a point that I've tried to make for several months now — as I put it (unhelpfully), "fiscal stimulus is an attempt to re-create the bubble conditions." Mario says it much better.)
