$800 bn of gains have been made on subprime-related liabilities since August 2007!
The sky must surely be falling on the financial sector. Reported or estimated subprime related losses have, since last summer, gone from $50bn, to $100bn, $200bn, $400bn, even $800bn. Let’s call it $1 trillion, or even $2 trillion, just to be sure we catch most of the likely eventual losses. What has not been reported is the matching subprime-related gains, which without a shadow of a doubt also follow the sequence $50bn, $100bn, $200bn, $400bn, $800bn, $1 trillion and $2 trillion. Why this failure to report the subprime-related gains?
One reason, no doubt, is that there is a lot of ignorance and stupidity around - the distinction between inside and outside assets appears to be a difficult one for economists, especially financial specialists, brought up in a partial equilibrium tradition. I am lucky in having had Jim Tobin as my PhD adviser and mentor. Balance sheet constraints, budget constraints, Walras’ Law, adding up constraints - it was the bread and butter of what he taught. A little general equilibrium does go a long way.
The second reason is that the losses are highly concentrated among a few hundred commercial banks, investment banks, hedge funds and similar shadow banking sector institutions, while the matching gains are widely dispersed among the many millions of homeowners who owed the mortgages that have been written down or written off. Mancur Olson’s Logic of Collective Action strikes again. In addition, many of the winners may not wish to advertise the fact, given the amount by which the value of their property fell, they are better off now because they were able to force the bank that held their mortgage to eat their negative equity.
