The Meaning of “Avoiding Another Depression”
Saturday, April 10th, 2010In a speech he gave earlier this week, Federal Reserve Chairman Ben Bernanke said the following:
“In the current episode, in contrast to the 1930s, policymakers around the world worked assiduously to stabilize the financial system. … As a result, although the economic consequences of the financial crisis have been painfully severe, the world was spared an even worse cataclysm that could have rivaled or surpassed the Great Depression.”
For today I want to set aside whether Ben’s claim is right and simply ask what it means. In particular, I want to discuss whether the events that might have occurred without Fed and Treasury intervention - widespread failure of financial institutions – should be thought of as generating economic costs or merely as redistributing wealth.
To that end, here is a description of what occurred during the housing bubble and burst. Market participants came to believe that housing prices were going to keep going up and up. Actors throughout the economy made decisions based on these beliefs, and the asset values on their balances sheets incorporated these beliefs.
Then one day everybody realized that fundamentals (land availability, construction costs, demographics) did not justify ever-increasing housing prices. And everyone recognized that assets backed by housing were about to be worth much less than everyone had previously believed.
At that point it was inevitable that all those assets backed by housing were going to decline in value. So the financial institutions that bet heavily on housing would suffer, and some would fail. Shareholders and creditors would lose a lot of money.
The crucial thing to note, however, is that so far in this story the declines in asset values have not caused any harm or loss of wealth other than that implied by the decline in housing prices. These losses are obviously bad for people who owned claims on housing, but the failures are not new or additional costs; they are just the reflections of a negative shock (the decline in housing values).
Further, if the surge in housing prices was a bubble, perhaps aided by ill-advised monetary and housing policies, then the decline toward fundamental values is good for economic efficiency. Specifically, the decline in housing prices suggests the economy should invest less in housing and more in factories and R&D.
So if this is the entire story, the failure of financial institutions is bad for their stakeholders, but not for anyone else. In wonko-speak, the failures per se are not an externality or inefficiency; they are the unavoidable undoing of a bubble.
So why does Ben argue that we had to prevent the financial failures? His claim is that when financial institutions fail, it harms the non-financial part of the economy. The reasoning is that when a financial firm fails, no one else can easiliy step in and make the productive loans this firm might have made. Thus productive opportunities are lost throughout the economy.
Is this story interesting? Yes. Has it been verified beyond reasonable doubt? I do not think so, but reasonable people can disagree.
What should be indisputable, however, is that the mere fact that we would have witnessed widespread failure, bankruptcy, and lower wealth for those invested in housing does not by itself justify intervention to prevent failures. An economically correct case for such intervention must argue that failures have negative externalities. I am far from convinced that would have been the case.
