I am slowly reaching the conclusion that the current debate over fiscal stimulus — like prior debates over monetary stimulus, and the causes of the financial crisis — has exposed the cluelessness of (many? most?) professional economists and ought to be considered an embarrassment to the profession.
There is a reason extremely smart economists are out there playing reputation games instead of trying to settle the matter by doing better science. The reason is that, on the questions that are provoking intramural trashtalk, there is no science.
