Why 3 versions?
As I've learned there is some confusion in the "blogosphere" about
why I "decided to write 3 reviews." The short answer is "I
didn't" and "I didn't intend to."
For what (possibly little) it's worth, the reality is that I was
asked to write one review and fully intended to have just
one review. When I submitted it to the JEL (the "original
version") below, I was asked to remove 2/3 of the original "parts"
of the review, which I did; I then submitted 1 of those 2/3s to
the ALER and consigned the remaining 1/3 to exist only on this
page as part of "the original version."
