Prize is awarded for research into how poor institutions affect countries’ success

The Nobel memorial prize in economics was awarded yesterday to Daron Acemoglu, Simon Johnson and James A. Robinson for research that explains why societies with poor rule of law and exploitative institutions do not generate sustainable growth.

The three economists “have demonstrated the importance of societal institutions for a country’s prosperity,” the Nobel committee of the Royal Swedish Academy of Sciences said at the announcement in Stockholm.

Acemoglu and Johnson work at the Massachusetts Institute of Technology and Robinson conducts his research at the University of Chicago.

“Reducing the vast differences in income between countries is one of our time’s greatest challenges. The laureates have demonstrated the importance of societal institutions for achieving this,” Jakob Svensson, Chair of the Committee for the Prize in Economic Sciences, said.

He said their research has provided “a much deeper understanding of the root causes of why countries fail or succeed.”

Reached by the academy in Athens, Greece, where he is due to speak at a conference, the Turkish-born Acemoglu, 57, said he was surprised and shocked by the award.

“You never expect something like this,” he said.

Acemoglu said the research honored by the prize underscores the value of democratic institutions.

“I think broadly speaking the work that we have done favors democracy,” he said in a telephone call with the Nobel committee and reporters in Stockholm.

But he added that “democracy is not a panacea. Introducing democracy is very hard. When you introduce elections, that sometimes creates conflict.”

Asked about how economic growth in countries like China fits into the theories, Acemoglu said that “my perspective is generally that these authoritarian regimes, for a variety of reasons, are going to have a harder time … in achieving … long-term sustainable innovation outcomes.”

Acemoglu and Robinson wrote the 2012 bestseller “Why Nations Fail: The Origins of Power, Prosperity, and Poverty,’’ which argued that manmade problems were responsible for keeping countries poor.

In their work, the winners looked, for instance, at the city of Nogales, which straddles the U.S.-Mexico border.

Despite sharing the same geography, climate, many of the same ancestors and a common culture, life is very different on either side of the border. In Nogales, Arizona, to the north, residents are relatively well-off and live long lives; most children graduate from high school. To the south, in Mexico’s Nogales, Sonora, “residents here are in general considerably poorer. … Organized crime makes starting and running companies risky. Corrupt politicians are difficult to remove,” the Nobel committee wrote.

The difference, the economists found, is a U.S. system that protects property rights and gives citizens a say in their government.

Acemoglu expressed worry yesterday that democratic institutions in the United States and Europe were losing support from the population. “Democracies particularly underperform when the population thinks they underdeliver,” he said. “This is a time when democracies are going through a rough patch. … It is, in some sense, quite crucial that they reclaim the high ground of better governance.”

The economists also studied the institutional changes that European powers such as Britain and Spain put in place when they colonized much of the world starting in the 1600s. They brought different policies to different places, giving later researchers a “natural experiment” to analyze.

Colonies that were sparsely populated offered less resistance to foreign rule and therefore attracted more settlers. In those places, colonial governments tended to establish more inclusive economic institutions that “incentivized settlers to work hard and invest in their new homeland. In turn, this led to demands for political rights that gave them a share of profits,” according to the Nobel committee.

In more densely populated places that attracted fewer settlers, the colonial regimes limited political rights and set up institutions that focused on “benefiting a local elite at the expense of the wider population … Paradoxically, this means that the parts of the colonized world that were relatively the most prosperous around 500 years ago are now those that are relatively poor.” India’s industrial production, for example, exceeded the American colonies’ in the 18th century.

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.

Though Nobel purists stress that the economics prize is technically not a Nobel Prize, 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.
