Life in the Echo Chamber
| Peter Klein |
You’ve all heard the story of the Manhattan socialite who expressed shock at Nixon’s landslide 1972 victory because “nobody I know voted for him.” (Attributed variously to Pauline Kael, Katharine Graham, Susan Sontag, and others, and probably apocryphal, but who cares; it’s a great quote.) I was reminded of this by a line in Larry Summers’s confidential 2008 economic policy memo now making the rounds, courtesy of the New Yorker: “Greg Mankiw is the only economist we have consulted with [about the optimal stimulus package] who refused to name a number and was generally skeptical about stimulus.” How can a huge stimulus package be wrong — everybody I know favors it!
(For the record, the economists consulted — supposedly representing the full spectrum of legitimate opinion — were Robert Reich (recommended stimulus: $1.2 trillion over 2 years), Joe Siglitz ($1 trillion over two years), Paul Krugman ($600 billion in one year), Jamie Galbraith ($900 billion in one year), Dean Baker and colleagues ($900 billion), Marty Feldstein ($400 billion in one year), Larry Lindsey ($800 billion to $1 trillion), Ken Rogoff ($1 trillion over two years), Mark Zandi ($600 billion in one year), an unnamed group of Fed officials (over $600 billion), Adam Posen ($500-700 billion in one year), and an unnamed group at Goldman Sachs(!) ($600 billion). So, we’ve got left-wing Keynesians, right-wing Keynesians, moderate Keynesians, Robert Reich who wouldn’t know a Keynesian from a Kenyan, and Goldman Sachs. How’s that for diversity of opinion?)
Update: Mankiw agrees: “Of course, the fact that I was ‘the only economist’ expressing skepticism reflects the range of economists that Team Obama chose to consult.”
