Sometimes the best way to solve a problem is to stop trying to solve it the way everyone else does. That, in one sentence, is the story of Robert E. Hall, who shares the 2026 Sveriges Riksbank Prize in Economic Sciences in Memory of Alfred Nobel with [Michael Woodford](https://thequantumoflight.com/article/michael-woodford-still-gave-his-exam-the-morning-he-won-the-nobel-prize), 'for microeconomic foundations of macroeconomic stabilisation'.

Hall was born in Palo Alto, California, in 1943. He earned his doctorate at the Massachusetts Institute of Technology in 1967, and he is a professor at Stanford University, a few miles from where he was born.

## When the Old Models Broke

For decades after John Maynard Keynes, governments steadied the economy with a simple toolkit. In a downturn, cut interest rates and spend more. In a boom, do the opposite. The models behind those decisions relied on stable links between big numbers such as inflation, unemployment and household income.

Then came the oil crises of the 1970s. Inflation rose even as unemployment rose. The link between income and spending wobbled. Policies designed to help made things worse, and the West endured years of low growth and high inflation. Many economists concluded that stabilisation policy had done more harm than good.

One key puzzle was spending. Theory said households decide how much to spend based on what they expect to earn in the future, not just what they earn today. But nobody can see expectations. Researchers searched for clues that would predict changes in spending, and none of them worked.

## The Upside-Down Question

Hall started thinking in an entirely new way. If households spend according to their expectations, he reasoned, then their spending is itself the best measure of those expectations. Optimistic households spend more, and pessimistic households spend less. They change their spending only when new information changes their view of the future. And new information, by definition, cannot be predicted, or it would not be new.

So instead of searching for a way to predict changes in spending, Hall proposed testing whether they could be predicted at all. In an article in 1978, he showed that they could not. The Nobel Committee describes it as something of a eureka moment. Even his most sceptical colleagues were convinced.

In 1982, working with Frederic Mishkin, Hall used data on individual households to show that around 80 per cent of them made their spending decisions in line with the theory. The rest lived hand to mouth. That insight, that some households look ahead and others cannot afford to, is built into the models central banks and finance ministries use today.

## What His Story Teaches You

[**When a question will not yield, turn it over**](https://thequantumoflight.com/article/henri-kagan-questioned-what-every-chemist-assumed-and-won-the-nobel-prize-at-95)**.** Hall did not find a better predictor. He asked whether prediction was possible at all. If you have been stuck on the same problem all year, try asking its opposite.

**Your spending shows what you expect.** Hall's insight works at your kitchen table too. Look at last month's bank statement. Does it reflect fear, hope or habit? Changing what you expect about the future is often the first step to changing how you spend.

**Not everyone can plan ahead, and that matters.** One household in five, in Hall's early work, lived hand to mouth. The economy is kinder when its policies remember them. So are we.

**Let your work become someone else's foundation.** Michael Woodford studied Hall's work in his first year as a graduate student. Decades later they share a Nobel Prize. Good work feeds the people who come after you.

## The Power of a Better Question

Hall's prize celebrates a model, but it also celebrates a habit of mind. When everyone around you is searching for the answer, the most valuable thing you can do may be to change the question.
