There's nothing better than financial crisis hindsight and earlier this month we got a big dose of it in the form of a 218-page paper by Laurence Ball, Department of Economics Chair at Johns Hopkins. In the paper, Ball makes the case that — contrary to statements by some policymakers — Lehman Brothers could have been rescued back in 2008 and the U.S. made a massive mistake in choosing not to do so. We talk to Ball about the genesis of the paper and what it means for markets today.
