Paul Krugman has been awarded the Nobel Prize in Economic Sciences for 2008. No matter what you think about his political views--he can be overly shrill at times and sometimes wrong (e.g. his assessment of Milton Friedman's legacy)--he is a first-rate economist with a remarkable academic record as noted by Tyler Cowen and Alex Tabarrok. Krugman also does a great job explaining complex economic issues to laypeople in his popular writings. For example, Slate magazine today, in recognition of his Nobel prize, reposted his Slate article titled "Baby-Sitting the Economy." Another great column, in my opinion, is his 2005 "Running Out of Bubbles" piece in the NY Times. When Krugman sticks to economics, as he does in these articles, he is at his best.
