Taming the Beast By
PAUL KRUGMANWe’re now in the midst of an epic financial crisis, which ought to be at the center of the election debate. But it isn’t.
Now, I don’t expect presidential campaigns to have all the answers to our current crisis — even financial experts are scrambling to keep up with events. But I do think we’re entitled to more answers, and in particular a clearer commitment to financial reform, than we’re getting so far.
In truth, I don’t expect much from John McCain, who has both admitted not knowing much about economics and denied having ever said that. Anyway, lately he’s been busy demonstrating that he doesn’t know much about the Middle East, either.
Yet the McCain campaign’s silence on the financial crisis has disappointed even my low expectations.
And when Mr. McCain’s economic advisers do speak up about the economy’s problems, they don’t inspire confidence. For example, last week one McCain economic adviser — Kevin Hassett, the co-author of “Dow 36,000” — insisted that everything would have been fine if state and local governments hadn’t tried to limit urban sprawl. Honest.
On the Democratic side, it’s somewhat disappointing that Barack Obama, whose campaign has understandably made a point of contrasting his early opposition to the Iraq war with Hillary Clinton’s initial support, has tried to score a twofer by suggesting that the war, in addition to all its other costs, is responsible for our economic troubles.
The war is indeed a grotesque waste of resources, which will place huge long-run burdens on the American public. But it’s just wrong to blame the war for our current economic mess: in the short run, wartime spending actually stimulates the economy. Remember, the lowest unemployment rate America has experienced over the last half-century came at the height of the Vietnam War.
Hillary Clinton has not, as far as I can tell, made any comparably problematic economic claims. But she, like Mr. Obama, has been disappointingly quiet about the key issue: the need to reform our out-of-control financial system.
Let me explain.
America came out of the Great Depression with a pretty effective financial safety net, based on a fundamental quid pro quo: the government stood ready to rescue banks if they got in trouble, but only on the condition that those banks accept regulation of the risks they were allowed to take.
Over time, however, many of the roles traditionally filled by regulated banks were taken over by unregulated institutions — the “shadow banking system,” which relied on complex financial arrangements to bypass those safety regulations.
Now, the shadow banking system is facing the 21st-century equivalent of the wave of bank runs that swept America in the early 1930s. And the government is rushing in to help, with hundreds of billions from the Federal Reserve, and hundreds of billions more from government-sponsored institutions like Fannie Mae, Freddie Mac and the Federal Home Loan Banks.
Given the risks to the economy if the financial system melts down, this rescue mission is justified. But you don’t have to be an economic radical, or even a vocal reformer like Representative Barney Frank, the chairman of the House Financial Services Committee, to see that what’s happening now is the quid without the quo.
Last week Robert Rubin, the former Treasury secretary, declared that Mr. Frank is right about the need for expanded regulation. Mr. Rubin put it clearly: If Wall Street companies can count on being rescued like banks, then they need to be regulated like banks.
But will that logic prevail politically?
Not if Mr. McCain makes it to the White House. His chief economic adviser is former Senator Phil Gramm, a fervent advocate of financial deregulation. In fact, I’d argue that aside from Alan Greenspan, nobody did as much as Mr. Gramm to make this crisis possible.
Both Democrats, by contrast, are running more or less populist campaigns. But at least so far, neither Democrat has made a clear commitment to financial reform.
Is that simply an omission? Or is it an ominous omen? Recent history offers reason to worry.
In retrospect, it’s clear that the Clinton administration went along too easily with moves to deregulate the financial industry. And it’s hard to avoid the suspicion that big contributions from Wall Street helped grease the rails.
Last year, there was no question at all about the way Wall Street’s financial contributions to the new Democratic majority in Congress helped preserve, at least for now, the tax loophole that lets hedge fund managers pay a lower tax rate than their secretaries.
Now, the securities and investment industry is pouring money into both Mr. Obama’s and Mrs. Clinton’s coffers. And these donors surely believe that they’re buying something in return.
Let’s hope they’re wrong.

Partying Like It’s 1929 By
PAUL KRUGMANIf Ben Bernanke manages to save the financial system from collapse, he will — rightly — be praised for his heroic efforts.
But what we should be asking is: How did we get here?
Why does the financial system need salvation?
Why do mild-mannered economists have to become superheroes?
The answer, at a fundamental level, is that we’re paying the price for willful amnesia. We chose to forget what happened in the 1930s — and having refused to learn from history, we’re repeating it.
Contrary to popular belief, the stock market crash of 1929 wasn’t the defining moment of the Great Depression. What turned an ordinary recession into a civilization-threatening slump was the wave of bank runs that swept across America in 1930 and 1931.
This banking crisis of the 1930s showed that unregulated, unsupervised financial markets can all too easily suffer catastrophic failure.
As the decades passed, however, that lesson was forgotten — and now we’re relearning it, the hard way.
To grasp the problem, you need to understand what banks do.
Banks exist because they help reconcile the conflicting desires of savers and borrowers. Savers want freedom — access to their money on short notice. Borrowers want commitment: they don’t want to risk facing sudden demands for repayment.
Normally, banks satisfy both desires: depositors have access to their funds whenever they want, yet most of the money placed in a bank’s care is used to make long-term loans. The reason this works is that withdrawals are usually more or less matched by new deposits, so that a bank only needs a modest cash reserve to make good on its promises.
But sometimes — often based on nothing more than a rumor — banks face runs, in which many people try to withdraw their money at the same time. And a bank that faces a run by depositors, lacking the cash to meet their demands, may go bust even if the rumor was false.
Worse yet, bank runs can be contagious. If depositors at one bank lose their money, depositors at other banks are likely to get nervous, too, setting off a chain reaction. And there can be wider economic effects: as the surviving banks try to raise cash by calling in loans, there can be a vicious circle in which bank runs cause a credit crunch, which leads to more business failures, which leads to more financial troubles at banks, and so on.
That, in brief, is what happened in 1930-1931, making the Great Depression the disaster it was. So Congress tried to make sure it would never happen again by creating a system of regulations and guarantees that provided a safety net for the financial system.
And we all lived happily for a while — but not for ever after.
Wall Street chafed at regulations that limited risk, but also limited potential profits. And little by little it wriggled free — partly by persuading politicians to relax the rules, but mainly by creating a “shadow banking system” that relied on complex financial arrangements to bypass regulations designed to ensure that banking was safe.
For example, in the old system, savers had federally insured deposits in tightly regulated savings banks, and banks used that money to make home loans. Over time, however, this was partly replaced by a system in which savers put their money in funds that bought asset-backed commercial paper from special investment vehicles that bought collateralized debt obligations created from securitized mortgages — with nary a regulator in sight.
As the years went by, the shadow banking system took over more and more of the banking business, because the unregulated players in this system seemed to offer better deals than conventional banks. Meanwhile, those who worried about the fact that this brave new world of finance lacked a safety net were dismissed as hopelessly old-fashioned.
In fact, however, we were partying like it was 1929 — and now it’s 1930.
The financial crisis currently under way is basically an updated version of the wave of bank runs that swept the nation three generations ago. People aren’t pulling cash out of banks to put it in their mattresses — but they’re doing the modern equivalent, pulling their money out of the shadow banking system and putting it into Treasury bills. And the result, now as then, is a vicious circle of financial contraction.
Mr. Bernanke and his colleagues at the Fed are doing all they can to end that vicious circle. We can only hope that they succeed. Otherwise, the next few years will be very unpleasant — not another Great Depression, hopefully, but surely the worst slump we’ve seen in decades.
Even if Mr. Bernanke pulls it off, however, this is no way to run an economy. It’s time to relearn the lessons of the 1930s, and get the financial system back under control.
