Americans Thomas Sargent and Christopher Sims share the 2011 Nobel prize in economics for providing ways to understand the impact of policy changes on the economy. The prize is based on old research that is of great interest in the current global financial crisis.
"The Royal Swedish Academy of Sciences has
decided1 to award the Sveriges Riksbank Prize in Economic Sciences in memory of Alfred Nobel, 2011, to Professor Thomas J. Sargent at New York University, New York, USA and Professor Christopher A. Sims at Princeton University, Princeton, USA," said Professor Staffan Normark.
Sixty-eight year-old Thomas Sargent is a professor of economics at New York University. Christopher Sims, also 68, is a professor of economics and
banking2 at Princeton University.
Thomas Sargent, 68, a professor at New York University who won the Nobel economics prize, teaches a class on October 10, 2011.
Both men have studied how economic policy, such as raising interest rates or cutting taxes, affects such variables as GDP and inflation.
Professor Sargent’s work was based on a study of inflation policies in the post-World War II era, when many countries
initially3 implemented4 a high-inflation policy.
Professor Sims’s so-called "vector auto-regression" analysis has been
applied5 to examine, among other things, how interest rates set by central banks affects the economy.
Central bankers and government officials use the work of the two men to determine how changes in policy affect the economy.
Their work has come under fire since the 2008 global financial crisis, however, as governments and central banks in Europe and the United States struggle to deal with serious economic problems.
Danny
Quay6, professor of economics at the London School of Economics, studied under Sargent. He called the choice "brilliant."
"The work that these two people did is going to be hugely important for
helping7 us properly
analyze8 how we come out of the current desperate financial situation we find ourselves in," said Quay.
But Sims told a news conference in Stockholm by telephone that resolving the current financial
turmoil9 is not going to be an easy task.
"I don't have any simple answer, but I think the methods that I have used, and Tom has developed, are central to finding our way out of this mess. I think they point to a way to try to
unravel10 why our serious problems develop and new research using these methods may help us lead us out of it," said Sims.
Both men carried out their research independently in the 1970s and 1980s. They will share the approximately $1.5 million prize.
