Nobel economics prize goes to 3 researchers for explaining innovation-driven economic growth

STOCKHOLM (AP) — Three researchers who probed the process of business innovation won the Nobel memorial prize in economics Monday for explaining how new products and inventions promote economic growth and human welfare, even as they leave older companies in the dust.

Their work was credited with helping economists better understand how ideas and technology succeed by disrupting established ways — a process as old as steam locomotives replacing horse-drawn wagons and as contemporary as e-commerce shuttering shopping malls.

The award was shared by Dutch-born Joel Mokyr, 79, who is at Northwestern University; Philippe Aghion, 69, who works at the Collège de France and the London School of Economics; and Canadian-born Peter Howitt, 79, who is at Brown University.

The winners were credited with better explaining and quantifying “creative destruction,” a key concept in economics that refers to the process in which beneficial new innovations replace — and thus destroy — older technologies and businesses.

The concept is usually associated with economist Joseph Schumpeter, who outlined it in his 1942 book “Capitalism, Socialism and Democracy.” Schumpeter called the concept “the essential fact about capitalism.”

The Nobel committee said Mokyr “demonstrated that if innovations are to succeed one another in a self-generating process, we not only need to know that something works, but we also need to have scientific explanations for why.”

Aghion and Howitt studied the mechanisms behind sustained growth, including in a 1992 article that offered a complex mathematical model for creative destruction that added new aspects not included in earlier models.

Examples of creative destruction include e-commerce disrupting retail, streaming services replacing videocassette and DVD rentals and internet advertising undermining newspaper advertising. A classic illustration is horse-cart whip makers put out of business by the automobile.

“The laureates’ work shows that economic growth cannot be taken for granted. We must uphold the mechanisms that underlie creative destruction, so that we do not fall back into stagnation,” said John Hassler, chair of the committee for the prize in economic sciences.

Howitt and Aghion’s model showed that markets with too few dominant companies can hinder innovation and growth — a concern that has been raised about industries such as telecommunications, social media platforms and airlines.

They found it was important to support people who are affected by changes while making it easy to move to more productive workplaces — to protect workers more than specific jobs. They also stressed the importance of social mobility, where a person's profession or trade is not defined by their parents' identity.

Mokyr has long been known as an optimist about technological innovation. About a decade ago, many economists took a more pessimistic view, arguing that inventions such as smartphones or even the internet had less of an economic impact than previous developments such as the airplane or the car.

Mokyr responded that because many new services were either cheap or free, their impact wasn’t evident in economic data, but they still provided enormous benefits.

In an interview with The Associated Press in 2015, he cited the music streaming service Spotify as an example of an “absolutely astonishing” innovation that economists had difficulty measuring. Mokyr noted he once owned more than 1,000 CDs and, before that, “I spent a large amount of my graduate student budget on vinyl records.” But now he could access a huge music library for a small monthly fee.

Mokyr, whose work stresses the need to be open to innovation and change, acknowledged that the disruption from new inventions often caused at least short-term job loss or reduced earnings for workers. Like many economists, he argued that the innovations also created new, unexpected jobs that offered fresh opportunities.

The Nobel committee noted that for much of human history, economic stagnation, rather than growth, was the norm. Starting with the Industrial Revolution in the 18th century, however, European and later other economies began to grow steadily.

Innovation — and how to foster it — is an urgent question in Europe, where a report by former European Central Bank head Mario Draghi argued that Europe faces a rising productivity gap with the U.S. in digital technology. Aghion said the challenge was for Europe to keep pace with the U.S. and China in innovation by promoting promote research and the venture capital financing to turn ideas into businesses.

The new tariffs, or import taxes, from U.S. President Donald Trump are “not good news for growth” but can be “a wake-up call for Europe,” he told AP. “We have to wake up. Because you know who will win in this competition? Those who innovate.”

Mokyr was still trying to get his morning coffee when he was reached by an AP reporter. He said he was shocked to win the prize.

“People always say this, but in this case I am being truthful — I had no clue that anything like this was going to happen,” he said.

His students had asked him about the possibility he would win the Nobel, he said. “I told them that I was more likely to be elected pope than to win the Nobel prize in economics — and I am Jewish, by the way.”

Mokyr will turn 80 next summer but said he has no plans to retire. “This is the type of job that I dreamed about my entire life,” he said.

He then hung up to go walk his dog.

One half of the 11 million Swedish kronor (nearly $1.2 million) prize goes to Mokyr, and the other half is shared by Aghion and Howitt. Winners also receive an 18-carat gold medal and a diploma.

The economics prize is formally known as the Bank of Sweden Prize in Economic Sciences in Memory of Alfred Nobel. The central bank established it in 1968 as a memorial to Nobel, the 19th-century Swedish businessman and chemist who invented dynamite and established the five Nobel Prizes.

Since then, it has been awarded 57 times to a total of 99 laureates. Only three of the winners have been women.

Nobel purists stress that the economics prize is technically not a Nobel Prize, but it is always presented together with the others on Dec. 10, the anniversary of Nobel’s death in 1896.

Nobel honors were announced last week in medicine, physics, chemistry, literature and peace.
