Last week I linked to my friend Bob Gelfond’s complaint [2] – quite justified, in my view – of the unscientific nature of much of the work on the Keynesian multiplier. Here’s a link to a website for a project that Bob launched for the purpose of assessing [3] (as the site says)
how well economists have demonstrated that the spending multiplier is greater than one. Specifically, we are seeking an “out-of-sample” (“OS”) test performed successfully. More on the importance of this form of testing can be found here [4].
At this site, you can also propose wagers, on this matter, with Bob.
