2 Americans Win Nobel Economics Prize for Boom-Bust Work

Two American economists were awarded the 2026 Nobel Prize in economic sciences on Monday for research that reshaped how governments and central banks fight recessions and inflation. Robert E. Hall of Stanford University and Michael Woodford of Columbia University received the award “for microeconomic foundations of macroeconomic stabilisation,” according to the Royal Swedish Academy of Sciences.

The prize, formally the Sveriges Riksbank Prize in Economic Sciences in Memory of Alfred Nobel, comes with 12 million Swedish kronor — roughly $1.1 million — shared equally between the two laureates. It is the 58th award in economic sciences, bringing the total number of laureates since 1969 to 101.

The Nobel Committee said the laureates “have helped us smooth out the economy’s peaks and troughs,” recognizing work that created the “New Keynesian” framework now embedded in the policy toolkit of central banks and finance ministries worldwide.

A Recipe That Stopped Working

Modern stabilization policy traces back to John Maynard Keynes, who argued during the Great Depression that governments should stimulate demand during downturns and cool it during booms. For decades, that approach appeared to work.

Then the 1970s delivered a shock the old models could not explain. Oil crises produced “stagflation” — high unemployment and high inflation at the same time — a combination Keynesian theory had treated as essentially impossible.

“This is the Keynesian recipe, and it worked well — until it didn’t,” Timo Boppart, a member of the prize committee, told NPR. “The Keynesian recipe was shattered.”

The problem, the committee explained, was that traditional models rested on assumed statistical relationships between aggregate variables such as inflation, output and consumption. When those relationships broke down, policymakers were left steering with a broken compass — and many economists concluded that active stabilization policy had done more harm than good.

Building Models From the Ground Up

Hall and Woodford took a different approach. Rather than model the economy as a set of statistical correlations, they built macroeconomic models “from the bottom up,” starting with how individual households and businesses actually make decisions.

Hall focused on the demand side, showing in a landmark 1978 paper that changes in household consumption cannot be predicted. The reason: consumers are forward-looking, basing spending on expectations of future income that shift only when genuinely new — and therefore unpredictable — information arrives. As Boppart put it, “If consumers see dark clouds on the horizon, they cut back on consumption already today.”

Woodford, in his 2003 book, assembled these insights into a complete New Keynesian model. It added staggered, forward-looking price-setting by firms — which anticipate costs over an extended period because changing prices carries friction — and introduced the “output gap” as a measure of demand pressure. The result is a three-equation prototype that functions as a laboratory for policymakers, letting them ask how GDP and inflation respond to a change in interest rates.

Because both households and businesses look ahead, expectations become a powerful policy lever. That insight gave rise to “forward guidance,” the practice of central banks signaling their likely future path for interest rates.

From Theory to Crisis Response

The practical stakes became clear in 2008. As The Guardian reported, New Keynesian models were used by policymakers to steer the global economy away from the risk of a second Great Depression. The models have since been deployed during the COVID-19 pandemic and the energy shocks that followed.

“The laureates’ work has provided us with a stable theoretical foundation for the models that are now used by central banks and governments around the world,” said John Hassler, chair of the Committee for the Prize in Economic Sciences. “With them, we are better equipped to deal with shocks in the economy, such as energy crises or sudden changes in how much households consume.”

Reaction from the laureates was immediate. Woodford told reporters he was “elated,” calling it “a tremendous honour… It’s a surprise but I’m feeling very good about it.” Columbia University President Jennifer L. Mnookin praised his “groundbreaking work alongside Robert E Hall that has fundamentally reshaped the theoretical foundations of stabilisation policy.”

A Live Policy Debate

Woodford used the moment to press an argument at the center of his research: that policymakers should explain themselves to the public. “Government authorities shouldn’t view stabilization of the economy as an exercise that is simply conducted by people pulling levers to control the economy, independent of what people in the economy understand,” he said, urging officials to communicate “why the things that are being done are being done.”

That view is under active debate at the Federal Reserve. NPR’s Scott Horsley noted that the Fed’s new chairman, Kevin Warsh, is skeptical of forward guidance, wanting to avoid getting locked into decisions, while some colleagues on the Federal Reserve Board argue the public needs to know what the Fed intends to do.

Forward guidance has drawn criticism before. In 2014, then-Bank of England governor Mark Carney was dubbed an “unreliable boyfriend” for hinting at interest rate rises that never materialized. Warsh has argued the tool should play only a “limited and circumscribed” role in normal times, to avoid “creating ambiguity in the name of clarity.”

What to Watch

Hall is also known for coining the “freshwater vs. saltwater” divide in economics — a nod to the inland universities (notably the University of Chicago) that champion free markets and rational expectations, versus the coastal institutions like MIT, Harvard and Columbia that embrace Keynesian thinking. Both laureates, notably, earned their doctorates at MIT.

The economics prize is not one of the five original awards established in Alfred Nobel’s will; it was created by Sweden’s central bank in 1968. The formal award ceremony will be held in Stockholm on the traditional date of 10 December.

As inflation tied to the war with Iran tests policymakers once again, the laureates’ core message — that clear communication shapes expectations, and expectations shape the economy — may prove as relevant as ever.
