DAVID LEONHARDT ESSAY

In 1929, Meyer Mishkin owned a shop in New York that sold silk shirts to workingmen. When the stock market crashed that October, he turned to his son, then a student at City College, and offered a version of this sentiment: It serves those rich scoundrels right.
A year later, as Wall Street’s problems were starting to affect the broader economy, Mr. Mishkin’s store went out of business. He no longer had enough customers. His son had to go to work to support the family, and Mr. Mishkin never held a steady job again.
Frederic Mishkin - Meyer’s grandson and, until he stepped down in August, an ally of Ben Bernanke’s on the Federal Reserve Board - told me this story the other day, and its moral is obvious enough. Many people in Washington fear that the country is starting to spiral into a terrible downturn. And to their horror, they see the public, and many members of Congress, turning into modern-day Meyer Mishkins, more interested in punishing Wall Street than saving the economy.
All of which may be true. But there is good reason for the public’s skepticism. The experts and policy makers have failed to tell a compelling story about why they’re so afraid.
It’s not enough to say that markets could freeze up, loans could become impossible to get and the economy could slide into its worst downturn since the Great Depression. For now, the crisis has had little effect on most Americans, beyond their retirement account statements. So the specter of a depression can sound alarmist.
Mr. Bernanke and his fellow worriers need to use their bully pulpits to teach a little lesson on the economics of a credit crisis .
Almost no economist thinks that even a terrible downturn would look like the Depression. The government has already responded more aggressively than it did in Herbert Hoover’s day. On October 3, Congress gave final approval to a $700 billion bailout for the financial system and central banks in the United States, England and Europe coordinated a cut in rates on Wednesday in an effort to stanch the financial crisis. So a Depression- like contraction - a 30 percent drop in economic activity - is highly unlikely.
But the Depression is still relevant, because the basic mechanics of how the economy might fall into a severe recession look quite similar to those that caused the Depression. In both cases, a credit crisis is at the center of the story.
At the start of the 1930s, despite everything that had happened on Wall Street, the American economy had not yet collapsed. Consumer spending and business investment were down, but not horribly so.
In late 1930, however, a rolling series of bank panics began. Investments made by the banks were going bad - or, in some cases, were rumored to be going bad - and nervous customers besieged bank branches to demand their money back. Hundreds of banks eventually closed.
Once a bank in a given town shut its doors, all the knowledge accumulated by the bank officers there effectively disappeared. Other banks weren’t nearly as willing to lend money to local businesses and residents because the loan officers at those banks didn’t know which borrowers were less reliable than they looked. Credit dried up.
“If a guy has a good investment opportunity and he can’t get the funding, he won’t do it,” Mr. Mishkin, who’s now an economics professor at Columbia, notes. “And that’s when the economy collapses.” By 1932, consumption and investment had both collapsed, and stocks had fallen more than 80 percent from their peak.
As a young academic economist in the 1980s, Mr. Bernanke largely developed the theory that the loan officers’ lost knowledge was a crucial cause of the Depression. He referred to this lost knowledge as “informational capital.” It means that trust vanished from the banking sector.
The same thing is happening now. Financial markets are global, not local, today, so the problem isn’t that the failure of any single bank locks individuals or businesses out of the credit markets. Instead, the nasty surprises of the last 13 months - the sort of turmoil that once would have been unthinkable - have caused an effective breakdown in informational capital.
The current fears can certainly seem irrational. Most households and businesses are still in fine shape, after all. So why aren’t some banks stepping into the void and taking advantage of the newly high interest rates to earn some profit?
There are two chief reasons. One is fairly basic: bankers are nervous that borrowers who look solid today may not turn out to be so solid. Think back to 1930, when the American economy seemed to be surviving the storm.
The second reason is a bit more complex. Banks own a lot of long-term assets (like mortgages) and hold a lot of shortterm debt (which is cheaper than longterm debt). To pay off this debt, they need to take out short-term loans.
In the current environment, bankers are nervous that other banks might shut them out, out of fear, and stop extending that short-term credit. This, essentially, brought about the collapse of Wachovia and Glitnir Bank in Iceland. To avoid their fate, other banks are hoarding capital, instead of making seemingly profitable loans. And when capital is hoarded, further bank failures become all the more likely.
The crucial point is that a modern economy can’t function when people can’t easily get credit. It takes a while for this to become obvious, since most companies and households don’t take out big new loans every day. But it will eventually become obvious, and painfully so. Already, a lack of car loans has caused vehicle sales to fall further.
In the end, this really isn’t about Wall Street. It’s about reducing the risk that something really bad happens. Unfortunately, there is no way to accomplish that without also extending a helping hand to Wall Street. That is where our credit markets are, and we need them to start working again.
“We are facing a major national crisis,” as Meyer Mishkin’s grandson says. “To do nothing right now is to do what was done during the Great Depression.”
