Given the rise in face time that economists are getting these days in the media, The Daily Beast has unveiled its list of "10 Hot Economists." And if you click through the slideshow, you'll quickly see that "hot" probably refers to their current stature and visibility, rather than some other measure of "hotness" (though their spouses may disagree).
At any rate, I find it interesting that an economist's current "hot" status appears to have a lot to do with being a Keynesian economist. This isn't necessarily true for all ten, but being a Keynesian sure seems to help.
The past couple of summers I have taught a course for Acton University called, "Why Keynesianism Failed." This summer's class will be especially interesting to teach, I think.
