Dear President Obama (a fantasy)


Please read Nate Silver’s new book.  Invite him to the white House.  So much of this budget business involves making predictions.  Silver knows predictions.  I’m sure you enjoyed his predictions last October and November (I sure did).  However he does more than predict election results.  His new book (as you probably already know) is called The Signal and the Noise: Why so Many Predictions Fail—but Some Don’t.  We often mistake the noise for the signal he says—that is we confuse the information that can help us make predictions—the signal—with the irrelevant information that surrounds it—the noise that is often mistaken for the signal. 

Much of his book is about distinguishing signal from noise.  It reminded me that many of our legislators know little about economics and, it seems to me, often mistake noise for meaningful signals.  Before they plan a budget, they need information about how to think about the results of their actions—predicting.

On page 22 Silver gives a short list of economists who predicted the end of the housing bubble:  Robert Shiller, Dean Baker, and Paul Krugman.  I think a seminar for legislatures would be good start to the coming budget talks, a seminar given by people who have a record for making good economic predictions.  Let Nate Silver help.

Silver can also help policy makers identify the phenomena that can be predicted.
