Here is the memo that Larry Summers sent to President Obama when the 2009 stimulus package was being debated. It was originally confidential, but somehow it has recently been made public and is now going viral.
I make a brief cameo appearance on page 11: "Greg Mankiw is the only economist we have consulted with who refused to name a number and was generally skeptical about stimulus." I explained my skepticism here. Of course, the fact that I was "the only economist" expressing skepticism reflects the range of economists that Team Obama chose to consult.
