Did mass hysteria cause the housing bubble?

A new report by the Federal Reserve Bank of Boston suggests that the mortgage crisis was caused not by bad policy or a failure of regulation but a shared delusion about home prices.

It wasn't caused by bad mortgage products, homeowners who were misled by mortgage pros or the easy availability of credit, argues a new report by the Federal Reserve Bank of Boston.


Instead, the bubble was caused by a collective euphoria on the part of homebuyers and mortgage investors over rising prices and the mistaken contention that home values would continue to rise.

Many of the factors that were blamed for the mortgage crisis — complicated adjustable-rate mortgages, complex securitization, lack of government regulation — are no more to blame for the housing bubble than they were for the Dutch tulip bubble of the 1630s, economistsChristopher Foote, Kristopher Gerardi and Paul Willen argue in their report.

The Wall Street Journal summarizes the 12 "facts" laid out in the report, starting with reporting that resets of adjustable-rate mortgages were not responsible for defaults.


The Boston Fed economists aren't the first to argue that "irrational exuberance" played a major role in the housing crisis. As early as 2005, Yale economist Robert Shiller wrote in a book of the same title that the housing bubble was going to burst.

The "bubble fever" infected both borrows and lenders, the Boston Fed report says.


"If both groups believe that house prices would continue to rise rapidly for the foreseeable future, then it is not surprising to find borrowers stretching to buy the biggest houses they could and investors lining up to give them the money," the economists wrote.


"… In short, higher house-price expectations rationalize the decisions of borrowers, investors and intermediaries — their embrace of high leverage when purchasing homes or funding mortgage investments, their failure to require rigorous documentation of income or assets before making loans, and their extension of credit to borrowers with histories of not repaying debt. … The bubble theory therefore explains the foreclosure crisis as a consequence of distorted beliefs rather than distorted incentives."

The last part of the report, where the authors discuss government policy in response to the crisis, is particularly interesting. The government response to the crisis has presumed that it was a failure of regulation and the structure of the mortgage market. But the authors contend that no amount of regulation would likely have tamped down the "mass delusion" that led to the bubble.


What do you think? Would more regulation have tempered the crisis? Or will we see another bubble, spurred by new delusions, sometime in the future?

Mass hysteria alone would not have caused the bubble.  It was definitely aided and abetted by toxic mortgage providers.  I've been out of luck trying to buy a home for about a decade now.  When I started looking in 2002 the prices kept going up and I was outbid on everything.  Stuff sold overnight, unless it had an inflated price.  It left you thinking that you'd never be able to get into a house if you didn't buy right then and there.  I think that fear was widespread and contributed to the mass hysteria phenomenon.  All sense flew out the window for the traditional homebuying process, mostly because the market was insane.  I figured the prices would drop again at some point in the future, and they have, but I'm still in the same boat, except now I can't get a loan for a decent amount.  Most of the houses in my price range seem to move quickly, get snapped up by investors with cash, or linger in short sale limbo forever.  For those of us here at the bottom rung of the property ladder the competition is still pretty fierce.  It's really really hard to buy your first home here in Los Angeles and I hope things get better soon 'cause I'm sick of renting!

The market here in Ann Arbor Michigan seems to be heading back in that direction.  Homes are selling for over-list price with multiple offers and in hours, not days!  I have clients who are losing house after house by higher bids.  This, of course, is pushing the prices of houses up in this area.  Hopefully it is not going too high too fast.
