Former U.S. Federal Reserve chair Ben Bernanke among 3 winners of Nobel in economics

This year's Nobel Prize in economic sciences has been awarded to the former chair of the U.S. Federal Reserve, Ben S. Bernanke, and two U.S.-based economists, Douglas W. Diamond and Philip H. Dybvig, "for research on banks and financial crises."

The prize was announced Monday by the Nobel panel at the Royal Swedish Academy of Sciences in Stockholm.

The committee said their work had shown in their research "why avoiding bank collapses is vital."

With their research in the early 1980s, the laureates laid the foundations for regulating financial markets and dealing with financial crises, the panel said.

Bernanke, 68, who is now with The Brookings Institution in Washington, D.C., examined the Great Depression of the 1930s, showing how dangerous bank runs when panicked savers withdraw their deposits can be.

Diamond, 68, based at the University of Chicago, and Dybvig, 67, who is at Washington University in St. Louis, showed how government guarantees on deposits can prevent a spiralling of financial crises. In 1983, they co-authored Bank Runs, Deposit Insurance, and Liquidity,which in part addressed damage from runs on banks.

Diamond said the Nobel came as a surprise. On Monday morning, he said, "I was sleeping very soundly and then all of a sudden, off went my cellphone" with good news from the Nobel committee.

'Much less vulnerable'

When it comes to the global economic turmoil created by the COVID-19 pandemic and Russia's war in Ukraine, Diamond said the financial system is "much, much less vulnerable" to crises because of memories of the 2000s collapse and improved regulation.

"The problem is that these vulnerabilities of the fear of runs and dislocations and crises can show up anywhere in the financial sector. It doesn't have to be commercial banks," he said.

The trio's research took on great real-world significance when investors sent the financial system into a panic during fall 2008.

Bernanke, then head of the Fed, teamed up with the U.S. Treasury Department to prop up major banks and ease a shortage of credit, the lifeblood of the economy.

Actions calmed investors

He slashed short-term interest rates to zero, directed the Fed's purchases of Treasury and mortgage investments and set up unprecedented lending programs. Collectively, those steps calmed investors and fortified big banks.

They also pushed long-term interest rates to historic lows and led to fierce criticism of Bernanke, particularly from some 2012 Republican presidential candidates, that the Fed was hurting the value of the dollar and running the risk of igniting inflation later.

The Fed's actions under Bernanke extended the authority of the central bank into unprecedented territory. They weren't able to prevent the longest and most painful recession since the 1930s. But in hindsight, the Fed's moves were credited with rescuing the banking system and avoiding another depression.

Nobel prizes carry a cash award of 10 million Swedish kronor (about $1.2 million Cdn) and will be handed out on Dec. 10.

Unlike the other prizes, the economics award wasn't established in Alfred Nobel's will of 1895 but by the Swedish central bank in his memory. The first winner was selected in 1969.

Last year, half of the award went to David Card for his research on how the minimum wage, immigration and education affect the labour market. The other half was shared by Joshua Angrist and Guido Imbens for proposing how to study issues that don't easily fit traditional scientific methods.

This year's winners

A week of Nobel Prize announcements kicked off Oct. 3 with Swedish scientist Svante Paabo receiving the award in medicine for unlocking secrets of Neanderthal DNA that provided key insights into our immune system.

Three scientists jointly won the prize in physics Tuesday. Frenchman Alain Aspect, American John F. Clauser and Austrian Anton Zeilinger had shown that tiny particles can retain a connection with each other even when separated, a phenomenon known as quantum entanglement, whichcan be used for specialized computing and to encrypt information.

The Nobel Prize in chemistry was awarded Wednesday to Americans Carolyn R. Bertozzi and K. Barry Sharpless, and Danish scientist Morten Meldal for developing a way of "snapping molecules together" that can be used to explore cells, map DNA and design drugs that can target diseases such as cancer more precisely.

French author Annie Ernaux won this year's Nobel Prize in literature Thursday. The panel commended her for blending fiction and autobiography in books that fearlessly mine her experiences as a working-class woman to explore life in France since the 1940s.

The Nobel Peace Prize went to jailed Belarus human rights activist Ales Bialiatski, the Russian group Memorial and the Ukrainian organization Center for Civil Liberties on Friday.
